Definitions

  • the invention relates to a device for attaching reinforcements to register inserts.
  • a device is known from US Pat. No. 4,588,463 for producing folded storage folders, which is provided on one narrow side with reinforced tabs.
  • the known machine is supplied with the base material for the filing folder from an endless roll, the web width being somewhat greater than the height of the finished filing folder, measured in the direction parallel to its folded back.
  • the continuously funded train is provided with an adhesive along one edge in a strip located on the top, while on the underside, opposite the strip, a plastic adhesive tape is applied, the width of which is more than twice as large as the depth of the tab created later.
  • the edge of the endless web provided with the reinforcement strip is turned upward by the machine, so that where the adhesive layer is provided, a double-layer arrangement is formed which carries along its outside the reinforcement tape which runs in the longitudinal direction of the web.
  • the machine cuts the tape where it is double-ply according to the tabs to be produced, to a depth that is less than the depth of the folded reinforcing bottom.
  • the finished folder therefore not only has the reinforcement in the area of the tab, i.e. at the point that is more exposed to wear, but there is reinforcement everywhere along the edge that carries the tab, which may be cut out.
  • This type of reinforcement for the folder requires a high consumption of film for the reinforcement, which is particularly uneconomical because a large part is cut away again after the reinforcement film has been attached. As a result, there is also a large amount of waste which, even if the base material for the folder consists of easily rotten paper, has a very high proportion of plastic and is accordingly difficult to dispose of.
  • the positioning of the reinforcement on the register insert in connection with pushing the reinforcement as far as possible onto the tabs is improved if the groove in the gripper has a V-shaped shape.
  • evasive movements are largely avoided, which could otherwise lead to play or a gap between the edge of the reinforcement and the edge of the register insert.
  • the reinforcement can be held in the groove of the gripper solely by means of its return force if projections to be pointed towards one another are provided on the two edges of the groove.
  • the longitudinally folded reinforcement is pressed against the walls of the groove due to its return force, while its movement out of the groove is stopped by the projections. As a result, it sits in a form-fitting manner in the groove of the gripper and cannot fall out when the gripper swivels.
  • the introduction of the reinforcement into the gripper is simplified by a slide which is displaceably guided opposite the groove in the area of the loading position.
  • the pre-folded reinforcement need not be pushed into the groove from the side, but is pushed into the groove from the front by means of the slider. This reliably prevents the reinforcement from striking the edges of the gripper.
  • the arrangement of the cutting device is simplified if the reinforcements are cut down from a strip coming from a supply reel.
  • the movement of the slider can be easily synchronized with the movement of the knife in that the slider is attached to the knife itself. This reliably prevents the reinforcement cut from the strip from falling off, in particular if the strip is only finally severed after the reinforcement has already been partially inserted at least into the groove of the gripper.
  • a device is located upstream, based on the transport movement of the strip for the reinforcements, which folds or folds the strip once in the longitudinal direction parallel to its two edges.
  • the cutting device is preferably provided with a die which has a correspondingly triangular shape Includes opening, the tip of which is directed to the groove, while the knife of the cutting device has a similar shape and the tip of the knife has the same orientation.
  • the cutting movement of the knife is a sliding movement directed towards the groove.
  • the gripper is designed as a drum which contains several equidistantly distributed grooves in its circumference, the longitudinal extent of which is parallel to the axis of rotation.
  • a drum rotation corresponding to the azimuth angle between two adjacent grooves is sufficient.
  • a further, previously emptied groove is brought into the loading position and can accommodate a new reinforcement.
  • a stapling device is provided so that the reinforcements after the transfer to the register insert are non-displaceably connected to the register insert until they are finally glued or welded.
  • this stapling device even longer reinforcements can be reliably provisionally fixed, if the stapling device has two sets of aligned tines which can be inserted into correspondingly arranged, circumferential grooves of the drum-like gripper. These grooves cut the V-shaped grooves for the reinforcements and allow the tines to temporarily connect the reinforcement to the stitching insert in several places.
  • the reinforcement to be attached to the register insert can be accommodated completely in the drum and does not have to project on one of the end faces of the drum.
  • an incompletely cut register insert 1 is illustrated, which consists of a rectangular cut sheet of paper or a sheet of thin cardboard.
  • the register insert 1 carries a continuous reinforcement strip 4 in order to protect a perforation 5 located in the vicinity of the rear edge 3.
  • the register insert 1 will have a tab 7 in the area of its front edge 6, which protrudes laterally from the front edge.
  • the register insert is cut out along dashed lines 7 and 8.
  • the tab 7 then protruding from the front edge 6 bears letters, numbers or other symbols in accordance with the desired sorting scheme - in the illustrated example it is the register insert with the letter B from an alphabetically marked sentence.
  • a reinforcement 9 is attached to the front edge 6, which is folded and on both the front and the back of the blank 2 is glued or welded on.
  • the reinforcement 9 envelops the free front edge of the tab 7 in one piece and, as can be seen in FIG. 1, extends upwards and downwards beyond the tab 7 so that it is cut out accordingly along the lines 7 and 8.
  • the position of the tab 7 on the front edge 6 is arranged as a function of the printed symbol, ie the distance of the tab from the upper edge of the register insert 1 is different. Accordingly The reinforcement 9 moves along the front edge 6 in order to minimize the material loss when cutting out along the lines 7 and 8, and on the other hand always to protect the tab 7.

Aus der US-PS 4 588 463 ist eine Vorrichtung bekannt, um gefaltete Ablagemappen herzustellen, die an einer Schmalseite mit verstärkten Tabs versehen ist.A device is known from US Pat. No. 4,588,463 for producing folded storage folders, which is provided on one narrow side with reinforced tabs.

Der bekannten Maschine wird von einer Endlosrolle das Grundmaterial für die Ablagemappe zugeführt, wobei die Bahnbreite etwas größer ist als es der Höhe der fertigen Ablagemappe, gemessen in Richtung parallel zu ihrem Faltrücken, entspricht. Die kontinuierlich geförderte Bahn wird längs der einen Kante in einem auf der Oberseite befindlichen Streifen mit einem Kleber versehen, während auf der Unterseite, dem Streifen gegenüberliegend, ein Kunststoffklebeband aufgebracht wird, dessen Breite mehr als doppelt so groß ist wie die Tiefe des später erzeugten Tabs. In einem späteren Schritt wird von der Maschine der mit dem Verstärkungsstreifen versehene Rand der endlosen Bahn nach oben umgeschlagen, so daß dort, wo die Klebschicht vorgesehen ist, eine doppellagige Anordnung zustandekommt, die längs ihrer Außenseite das in Längsrichtung der Bahn durchlaufende Verstärkungsband trägt.The known machine is supplied with the base material for the filing folder from an endless roll, the web width being somewhat greater than the height of the finished filing folder, measured in the direction parallel to its folded back. The continuously funded train is provided with an adhesive along one edge in a strip located on the top, while on the underside, opposite the strip, a plastic adhesive tape is applied, the width of which is more than twice as large as the depth of the tab created later. In a later step, the edge of the endless web provided with the reinforcement strip is turned upward by the machine, so that where the adhesive layer is provided, a double-layer arrangement is formed which carries along its outside the reinforcement tape which runs in the longitudinal direction of the web.

Schließlich wird von der Maschine das Band, dort wo es doppellagig ist, entsprechend den zu erzeugenden Tabs ausgeschnitten, und zwar mit einer Tiefe, die geringer ist als die Tiefe des umgeschlagenen Verstärkungsbodens.Finally, the machine cuts the tape where it is double-ply according to the tabs to be produced, to a depth that is less than the depth of the folded reinforcing bottom.

Die fertige Faltmappe weist deswegen die Verstärkung nicht nur im Bereich des Tab auf, also an der Stelle, die dem Verschleiß verstärkt ausgesetzt ist, sondern es ist überall längs der Kante, die den Tab trägt, die Verstärkung vorhanden, die gegebenenfalls ausgeschnitten ist.The finished folder therefore not only has the reinforcement in the area of the tab, i.e. at the point that is more exposed to wear, but there is reinforcement everywhere along the edge that carries the tab, which may be cut out.

Diese Art von Verstärkung für die Faltmappe bedingt einen hohen Verbrauch an Folie für die Verstärkung, was deswegen besonders unwirtschaftlich ist, weil im Anschluß an das Anbringen der Verstärkungsfolie ein großer Teil wieder weggeschnitten wird. Es entsteht folglich auch eine große Menge Abfall, der selbst dann, wenn das Grundmaterial für die Faltmappe aus leicht verrottbarem Papier besteht, einen sehr hohen Kunststoffanteil aufweist und dementsprechend schwierig zu entsorgen ist.This type of reinforcement for the folder requires a high consumption of film for the reinforcement, which is particularly uneconomical because a large part is cut away again after the reinforcement film has been attached. As a result, there is also a large amount of waste which, even if the base material for the folder consists of easily rotten paper, has a very high proportion of plastic and is accordingly difficult to dispose of.

Ausgehend hiervon ist es Aufgabe der Erfindung, eine Maschine zu schaffen, mit der es möglich ist, die Verstärkungen im wesentlichen nur im Bereich des Tabs anzubringen, während die später weggeschnittenen Teile im wesentlichen frei von den Verstärkungen sind.Proceeding from this, it is an object of the invention to provide a machine with which it is possible to attach the reinforcements essentially only in the area of the tab, while the parts cut away later are essentially free of the reinforcements.

Diese Aufgabe wird erfindungsgemäß durch die Vorrichtung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved according to the invention by the device with the features of claim 1.

Die Verwendung eines um eine Drehachse drehbaren Greifers , der zur Aufnahme der Verstärkung eine durchgehende Nut aufweist, hat den Vorteil, daß die Bewegung zum Anlegen der Verstärkung an die Registereinlage die natürliche Bewegung der Registereinlage bei ihrem Transport durch die Maschine mit verwenden kann und eine eigene translatorische Bewegung des Greifers zum Überstülpen der Verstärkung entbehrlich ist. Es genügt bei dieser Anordnung, wenn die an dem Greifer vorbeibewegte Registereinlage zum Anbringen der Verstärkung durch die entsprechend ausgerichtete Nut des Greifers hindurchgeführt wird und während des Anheftens kurz stoppt. Nach dem Verlassen des Greifers kann dieser ungehindert in die Beschickungsstellung schwenken, was nur sehr geringe Zeit beansprucht. Es sind geringe Massen zu beschleunigen und zu verzögern, wobei Drehbewegungen den Vorteil des geringen mechanischen Aufwandes mit sich bringen, während andererseits eine hohe Präzision und Leichtgängigkeit erreicht wird.The use of a gripper rotatable about an axis of rotation, which has a continuous groove for receiving the reinforcement, has the advantage that the movement for applying the reinforcement to the register insert can use the natural movement of the register insert during its transport through the machine and its own translatory movement of the gripper to put on the reinforcement is unnecessary. With this arrangement, it suffices if the register insert which is moved past the gripper for attaching the reinforcement is guided through the correspondingly aligned groove of the gripper and stops briefly during the attachment. After leaving the gripper, it can swing freely into the loading position, which takes up very little time. Small masses have to be accelerated and decelerated, whereby rotary movements have the advantage of low mechanical expenditure, while on the other hand high precision and smoothness are achieved.

Das Positionieren der Verstärkung an der Registereinlage in Verbindung mit einem möglichst weiten Aufschieben der Verstärkung auf die Tabs wird verbessert, wenn die Nut in dem Greifer eine V-förmige Gestalt hat. Beim Anheften der Verstärkung an die Registereinlage werden dadurch Ausweichbewegungen weitgehend vermieden, die sonst zu einem Spiel oder einer Lücke zwischen der Kante der Verstärkung und der Kante der Registereinlage führen könnten.The positioning of the reinforcement on the register insert in connection with pushing the reinforcement as far as possible onto the tabs is improved if the groove in the gripper has a V-shaped shape. When attaching the reinforcement to the register insert, evasive movements are largely avoided, which could otherwise lead to play or a gap between the edge of the reinforcement and the edge of the register insert.

Die Verstärkung läßt sich allein mit Hilfe ihrer Rücksprungkraft in der Nut des Greifers halten, wenn an den beiden Rändern der Nut aufeinander zu weisende Vorsprünge vorgesehen sind. Die in Längsrichtung gefaltete Verstärkung wird aufgrund ihrer Rücksprungkraft an die Wände der Nut angepreßt, während ihre Bewegung aus der Nut heraus von den Vorsprüngen aufgehalten wird. Sie sitzt dadurch formschlüssig gehalten in der Nut des Greifers und kann bei der Schwenkbewegung des Greifers in keinem Falle herausfallen.The reinforcement can be held in the groove of the gripper solely by means of its return force if projections to be pointed towards one another are provided on the two edges of the groove. The longitudinally folded reinforcement is pressed against the walls of the groove due to its return force, while its movement out of the groove is stopped by the projections. As a result, it sits in a form-fitting manner in the groove of the gripper and cannot fall out when the gripper swivels.

Das Einführen der Verstärkung in den Greifer wird durch einen Schieber vereinfacht, der im Bereich der Beschickungsstellung der Nut gegenüberliegend verschieblich geführt ist. Die vorgefaltete Verstärkung braucht bei der Verwendung des Schiebers nicht von der Seite her in die Nut eingeschoben zu werden, sondern sie wird von vorne mittels des Schiebers in die Nut hereingedrückt. Das Anstoßen der Verstärkung an den Kanten des Greifers wird dadurch sicher vermieden. Außerdem vereinfacht sich die Anordnung der Schneidvorrichtung, wenn die Verstärkungen von einem von einer Vorratsspule kommenden Streifen heruntergeschnitten werden. Dabei kann die Bewegung des Schiebers mit der Bewegung des Messers auf einfache Weise dadurch synchronisiert werden, daß der Schieber an dem Messer selbst angebracht wird. Ein Herunterfallen der vom Streifen abgeschnittenen Verstärkung ist hierdurch sicher verhindert, insbesondere dann, wenn der Streifen erst endgültig durchgetrennt wird, nachdem bereits die Verstärkung zum Teil zumindest in die Nut des Greifers eingeführt ist.The introduction of the reinforcement into the gripper is simplified by a slide which is displaceably guided opposite the groove in the area of the loading position. When the slider is used, the pre-folded reinforcement need not be pushed into the groove from the side, but is pushed into the groove from the front by means of the slider. This reliably prevents the reinforcement from striking the edges of the gripper. In addition, the arrangement of the cutting device is simplified if the reinforcements are cut down from a strip coming from a supply reel. The movement of the slider can be easily synchronized with the movement of the knife in that the slider is attached to the knife itself. This reliably prevents the reinforcement cut from the strip from falling off, in particular if the strip is only finally severed after the reinforcement has already been partially inserted at least into the groove of the gripper.

Günstige Platzverhältnisse ergeben sich, wenn die Beschickungsstellung gegenüber der Übergabestellung um 180° bezüglich der Drehachse des Greifers versetzt ist.Favorable space conditions result when the loading position is offset by 180 ° with respect to the axis of rotation of the gripper relative to the transfer position.

Um ein zu starkes Aufspringen der Verstärkung zu vermeiden, sitzt, bezogen auf die Transportbewegung des Streifens für die Verstärkungen, stromaufwärts eine Vorrichtung, die den Streifen in Längsrichtung parallel zu seinen beiden Kanten einmal zusammenfaltet oder -falzt.In order to avoid excessive opening of the reinforcement, a device is located upstream, based on the transport movement of the strip for the reinforcements, which folds or folds the strip once in the longitudinal direction parallel to its two edges.

Um bei einem V-förmigen gefalteten Streifen zu vermeiden, daß beim Abschneiden der entstehende Grat die beiden Schichten des Streifens geschlossen hält, was zu einem Unwirksamwerden der Vorsprünge an der Nut führen könnte, ist vorzugsweise die Schneideinrichtung mit einer Matrize versehen, die eine entsprechend dreieckförmige Öffnung enthält, deren Spitze auf die Nut gerichtet ist, während das Messer der Schneidvorrichtung eine ähnliche Gestalt aufweist und die Spitze des Messers die gleiche Ausrichtung hat. Die Schneidbewegung des Messers ist eine auf die Nut gerichtete Verschiebebewegung.In order to avoid, in the case of a V-shaped folded strip, that the resulting burr keeps the two layers of the strip closed when cutting, which could lead to the projections on the groove becoming ineffective, the cutting device is preferably provided with a die which has a correspondingly triangular shape Includes opening, the tip of which is directed to the groove, while the knife of the cutting device has a similar shape and the tip of the knife has the same orientation. The cutting movement of the knife is a sliding movement directed towards the groove.

Die Zeiten, die benötigt werden, um eine neue Verstärkung in den Weg einer ankommenden Registereinlage zu bringen, werden verkürzt, wenn der Greifer als Trommel ausgebildet ist, die in ihrem Umfang mehrere äquidistant verteilte Nuten enthält, deren Längserstreckung zu der Drehachse parallel ist. Zum Überführen einer neuen Verstärkung in die Übergabestellung genügt eine Trommeldrehung entsprechend dem Azimutwinkel zwischen zwei benachbarten Nuten. Gleichzeitig wird eine weitere, zuvor entleerte Nut in die Beschickungsstellung gebracht und kann eine neue Verstärkung aufnehmen.The times required to bring a new reinforcement in the way of an incoming register insert are shortened if the gripper is designed as a drum which contains several equidistantly distributed grooves in its circumference, the longitudinal extent of which is parallel to the axis of rotation. To transfer a new reinforcement into the transfer position, a drum rotation corresponding to the azimuth angle between two adjacent grooves is sufficient. At the same time, a further, previously emptied groove is brought into the loading position and can accommodate a new reinforcement.

Damit die Verstärkungen nach der Überführung auf die Registereinlage bis zum endgültigen Verkleben oder Verschweißen mit der Registereinlage unverschieblich verbunden sind, ist eine Hefteinrichtung vorgesehen. Mit dieser Hefteinrichtung lassen sich auch längere Verstärkungen zuverlässig provisorisch fixieren, wenn die Hefteinrichtung zwei Sätze von aufeinander ausgerichteten Zinken aufweist, die in entsprechende angeordnete, in Umfangsrichtung verlaufende Nuten des trommelartigen Greifers einführbar sind. Diese Nuten schneiden die V-förmigen Nuten für die Verstärkungen und gestatten es den Zinken, die Verstärkung an mehreren Stellen provisorisch mit der Hefteinlage zu verbinden. Infolge der in der Trommel verlaufenden Nuten kann die an der Registereinlage anzubringende Verstärkung vollständig in der Trommel untergebracht werden und braucht nicht etwa an einer der Stirnseiten der Trommel vorzustehen.A stapling device is provided so that the reinforcements after the transfer to the register insert are non-displaceably connected to the register insert until they are finally glued or welded. With this stapling device, even longer reinforcements can be reliably provisionally fixed, if the stapling device has two sets of aligned tines which can be inserted into correspondingly arranged, circumferential grooves of the drum-like gripper. These grooves cut the V-shaped grooves for the reinforcements and allow the tines to temporarily connect the reinforcement to the stitching insert in several places. As a result of the grooves running in the drum, the reinforcement to be attached to the register insert can be accommodated completely in the drum and does not have to project on one of the end faces of the drum.

In Fig. 1 ist eine nicht vollständig zurechtgeschnittene Registereinlage 1 veranschaulicht, die aus einem rechteckig geschnittenen Blatt Papier oder einem Blatt aus dünner Pappe besteht. Längs ihrer Rückkante 3 trägt die Registereinlage 1 einen durchgehenden Verstärkungsstreifen 4, um eine in der Nähe der Rückkante 3 befindliche Lochung 5 zu schützen. Nach dem endgültigen Zuschnitt wird die Registereinlage 1 im Bereich ihrer Vorderkante 6 ein Tab 7 aufweisen, das seitlich aus der Vorderkante vorsteht. Zu diesem Zweck wird die Registereinlage längs gestrichelter Linien 7 und 8 ausgeschnitten. Der sodann aus der Vorderkante 6 vorstehende Tab 7 trägt entsprechend dem gewünschten Sortierschema Buchstaben, Ziffern oder andere Symbole - im veranschaulichten Beispiel handelt es sich um die Registereinlage mit dem Buchstaben B aus einem alphabetisch gekennzeichneten Satz.In Fig. 1, an incompletely cut register insert 1 is illustrated, which consists of a rectangular cut sheet of paper or a sheet of thin cardboard. Along its rear edge 3, the register insert 1 carries a continuous reinforcement strip 4 in order to protect a perforation 5 located in the vicinity of the rear edge 3. After the final cutting, the register insert 1 will have a tab 7 in the area of its front edge 6, which protrudes laterally from the front edge. For this purpose, the register insert is cut out along dashed lines 7 and 8. The tab 7 then protruding from the front edge 6 bears letters, numbers or other symbols in accordance with the desired sorting scheme - in the illustrated example it is the register insert with the letter B from an alphabetically marked sentence.

Um das Tab 7 gegen alsbaldige Beschädigung im Gebrauch zu schützen, ist vor dem endgültigen Zuschneiden längs der gestrichelten Linien 7 und 8 an der Vorderkante 6 eine Verstärkung 9 angebracht, die gefaltet ist und sowohl auf der Vorder- als auch auf der Rückseite des Zuschnittes 2 aufgeklebt bzw. aufgeschweißt ist. Die Verstärkung 9 umhüllt einstückig die freie Vorderkante des Tabs 7 und erstreckt sich, wie Fig. 1 erkennen läßt, nach oben und nach unten über den Tab 7 hinaus, damit er beim Schneiden entlang der Linien 7 und 8 entsprechend mit ausgeschnitten wird.In order to protect the tab 7 against immediate damage in use, before the final cutting along the dashed lines 7 and 8 a reinforcement 9 is attached to the front edge 6, which is folded and on both the front and the back of the blank 2 is glued or welded on. The reinforcement 9 envelops the free front edge of the tab 7 in one piece and, as can be seen in FIG. 1, extends upwards and downwards beyond the tab 7 so that it is cut out accordingly along the lines 7 and 8.

Es versteht sich, daß, wie bei Registereinlagen üblich, die Lage des Tabs 7 an der Vorderkante 6 von dem aufgedruckten Symbol abhängig angeordnet ist, d.h. der Abstand des Tabs von der Oberkante der Registereinlage 1 ist unterschiedlich groß. Dementsprechend wandert die Verstärkung 9 längs der Vorderkante 6, um den Materialverlust beim Ausschneiden längs der Linien 7 und 8 zu minimieren, andererseits immer den Tab 7 zu schützen.It goes without saying that, as is customary in the case of register inserts, the position of the tab 7 on the front edge 6 is arranged as a function of the printed symbol, ie the distance of the tab from the upper edge of the register insert 1 is different. Accordingly The reinforcement 9 moves along the front edge 6 in order to minimize the material loss when cutting out along the lines 7 and 8, and on the other hand always to protect the tab 7.

Um die Verstärkung 9 an dem Zuschnitt 2 anzubringen, ist die in Fig. 2 stark schematisiert dargestellte Vorrichtung 11 vorgesehen. Die selbstverständlichen Teile wie Lager, Rahmen u.dgl. sind der Übersichtlichkeit halber weggelassen, um die Zeichnung nicht mit Einzelheiten zu überladen, die für das Verständnis des Aufbaus und der Wirkungsweise der Vorrichtung 11 nicht notwendig sind.In order to attach the reinforcement 9 to the blank 2, the device 11 shown in a highly schematic manner in FIG. 2 is provided. The natural parts such as bearings, frames and the like. are omitted for the sake of clarity so as not to overload the drawing with details which are not necessary for understanding the structure and mode of operation of the device 11.

Die Vorrichtung 11 setzt sich im wesentlichen zusammen aus einer Transporteinrichtung 12 zum Transportieren der Zuschnitte 2, einer Zuführeinrichtung 13, mit der die Verstärkungen 9 zu der Registereinlage 1 überführt werden, einer Schneideinrichtung 14, die dem Abschneiden der Verstärkungen 9 von einem Vorratsstreifen 15 dient,sowie einer Hefteinrichtung 16, um provisorisch die Verstärkungen 9 an der jeweiligen Registereinlage 2 anzuheften. Die richtige Position der Registereinlage 2 wird mit Hilfe einer Anschlageinrichtung 17 eingestellt, deren Aufbau im einzelnen in den Fig. 5 und 6 zu sehen ist.The device 11 essentially consists of a transport device 12 for transporting the blanks 2, a feed device 13 with which the reinforcements 9 are transferred to the register insert 1, a cutting device 14 which serves to cut the reinforcements 9 off a supply strip 15, and a stitching device 16 to temporarily attach the reinforcements 9 to the respective register insert 2. The correct position of the register insert 2 is set with the aid of a stop device 17, the structure of which can be seen in detail in FIGS. 5 and 6.

Die Transporteinrichtung 12 enthält zwei parallel mit Abstand zueinander drehbar gelagerte walzenförmige Umlenkrollen, von denen aus Darstellungsgründen lediglich die Rolle 18 sichtbar ist, die, bezogen auf den Weg der Registereinlagen 2, stromaufwärts gelegen ist. Die Umlenkrolle 18 ist mit einer Antriebseinrichtung 19 gekuppelt, über die sie wahlweise in Umdrehungen zu versetzen ist. Um die beiden Umlenkrollen 18 führen zwei endlose Förderriemen herum, auf deren oben laufendem Arbeitstrum die Registereinlagen 1 durch reibschlüssige Mitnahme transportiert werden.The transport device 12 contains two parallel roller-shaped deflecting rollers, of which only the roller 18, which is located upstream in relation to the path of the register inserts 2, is visible for reasons of illustration. The deflection roller 18 is coupled to a drive device 19, by means of which it can optionally be set in revolutions. Guide around the two guide rollers 18 two endless conveyor belts around, the register inserts 1 are transported by frictional entrainment on the working run above.

Das Arbeitstrum der beiden Transportriemen 21 legt den Weg fest, längs dessen die Registereinlagen 1 transportiert werden.The working span of the two transport belts 21 defines the path along which the register inserts 1 are transported.

Neben dem in Fig. 2 rechts befindlichen Transportriemen ist die Zuführeinrichtung 13 angeordnet. Diese enthält eine zylindrische Trommel 22, die um ihre Längsachse 23 drehbar gelagert ist. Sie dient als Greifer für die Verstärkungen 9, um diese in den Weg der Registereinlagen 1 zu überführen. Ihre Drehachse 23 verläuft parallel zu dem Arbeitstrum der beiden Transportriemen 21 und damit parallel zum Weg, entlang dem die Registereinlagen 1 an der Zuführeinrichtung 13 vorbei bzw. hindurch transportiert werden. Die zylindrische Trommel 22 hat zwei zueinander parallele Stirnseiten 24 und 25 sowie eine zylindrische Außenumfangsfläche 26, in der bei dem gezeigten Ausführungsbeispiel insgesamt sechs V-förmige Nuten 27 enthalten sind. Die Nuten 27 durchsetzen beide Stirnseiten 25 und ihre ansonsten ebenen Seitenwände 28 und 29 divergieren zur Außenumfangsfläche 26, und zwar verlaufen sie unter dem jeweils gleichen Winkel gegenüber einem Radius, der durch die Schnittlinie der beiden Seitenwände 28, 29 der jeweiligen Nut 27 führt.In addition to the conveyor belt located on the right in FIG. 2, the feed device 13 is arranged. This contains a cylindrical drum 22 which is rotatably mounted about its longitudinal axis 23. It serves as a gripper for the reinforcements 9 in order to transfer them into the path of the register inserts 1. Its axis of rotation 23 runs parallel to the working run of the two transport belts 21 and thus parallel to the path along which the register inserts 1 are transported past or through the feed device 13. The cylindrical drum 22 has two mutually parallel end faces 24 and 25 and a cylindrical outer peripheral surface 26, in which a total of six V-shaped grooves 27 are contained in the exemplary embodiment shown. The grooves 27 pass through both end faces 25 and their otherwise flat side walls 28 and 29 diverge to the outer circumferential surface 26, namely they run at the same angle in each case with respect to a radius which leads through the intersection line of the two side walls 28, 29 of the respective groove 27.

Die Trommel 22 ist ortsfest drehbar gelagert und über eine Welle 31 mit einem Schrittmotorantrieb 32 gekuppelt, durch den die Trommel 22 jeweils um den winkelmäßigen Abstand zweier benachbarter Nuten 27 gesteuert weiterzudrehen und stillzusetzen ist. Wegen der äquidistanten Verteilung der Nuten 27 längs dem Umfang der Trommel 22 ist dieser Drehwinkel von Nut zu Nut jeweils gleich.The drum 22 is rotatably mounted in a stationary manner and is coupled via a shaft 31 to a stepper motor drive 32, by means of which the drum 22 can be rotated and stopped in a controlled manner by the angular distance between two adjacent grooves 27. Because of the equidistant distribution of the grooves 27 along the circumference of the drum 22, this angle of rotation from groove to groove is the same in each case.

Die Nuten 27 haben über ihre gesamte Länge gleiche Querschnittsgestalt, weshalb ihre Ränder 33 und 34 parallel und mit Abstand zueinander verlaufen. Wie insbesondere Fig. 3 erkennen läßt, ist jede der Nuten 27 an ihren beiden Rändern 33 und 34 mit leistenförmigen Fortsätzen 35, 36 versehen, die sich aus der zugehörigen Wand 28 bzw. 29 geringfügig erheben und über die gesamte Länge der Nut 27 durchlaufen. Die Erhöhungen 35, 36 haben den Zweck, in der später erläuterten Weise die in die Nut 27 eingelegte Verstärkung 9 festzuhalten.The grooves 27 have the same cross-sectional shape over their entire length, which is why their edges 33 and 34 run parallel and at a distance from one another. As can be seen in particular in FIG. 3, each of the grooves 27 is provided on its two edges 33 and 34 with strip-shaped projections 35, 36 which rise slightly from the associated wall 28 and 29 and pass over the entire length of the groove 27. The elevations 35, 36 have the purpose of holding the reinforcement 9 inserted into the groove 27 in the manner explained later.

Die Schneideinrichtung 14 enthält eine neben der stromaufwärts gelegenen Stirnseite 25 angeordnete Matrize 37, deren plan geschliffene Schneidfläche 39 sich parallel zu der Stirnseite 25 erstreckt. In der Matrize 37 befindet sich, wie Fig. 4 am besten erkennen läßt, eine dreieckförmige Öffnung 38, die eine ähnliche Gestalt wie die Nuten 27 hat, jedoch, verglichen mit diesen, einen kleineren Öffnungswinkel. Die Öffnung 38 fluchtet in der entsprechenden Stellung der Trommel 22 mit einer jeweiligen Nut 27, hat jedoch einen etwas größeren radialen Abstand von der Drehachse 23 als die mit ihr fluchtende Nut 27, so daß der durch sie hindurchführende Streifen 15 ungehindert in die mit ihr fluchtende Nut 27 von der Seite her eingeschoben werden kann.The cutting device 14 contains a die 37 which is arranged next to the upstream end face 25 and whose flat-ground cutting surface 39 extends parallel to the end face 25. 4, there is a triangular opening 38, which has a similar shape to the grooves 27, but, compared to these, a smaller opening angle, as best shown in FIG. The opening 38 is aligned in the corresponding position of the drum 22 with a respective groove 27, but has a somewhat greater radial distance from the axis of rotation 23 than the groove 27 aligned with it, so that the strip 15 passing therethrough unimpeded into the one aligned with it Groove 27 can be inserted from the side.

Auf der plan geschliffenen Fläche 39 der Schneidmatrize 37 gleitet ein Schneidmesser 41, das an einem Schieber 42 angeformt ist, hin- und her. Das Schneidmesser 41 hat eine Querschnittsgestalt entsprechend der Grundfläche der Öffnung 38, wobei die Spitze des Schneidmessers 41 ebenso wie die Spitze der Öffnung 38 in Richtung auf die Drehachse 23 zeigen.A cutting knife 41, which is formed on a slide 42, slides back and forth on the flat-ground surface 39 of the cutting die 37. The cutting knife 41 has a cross-sectional shape corresponding to the base area of the opening 38, the tip of the cutting knife 41 and the tip of the opening 38 pointing in the direction of the axis of rotation 23.

Mit der Rückseite des Schiebers 42 ist eine Schubstange 43 verbunden, die in einer Buchse 44 längsverschieblich geführt ist. Die Verschiebebewegung ist rechtwinklig zu der Drehachse 23. Mit dem hinteren Ende der zylindrischen Schubstange 43 ist eine Kniehebelanordnung 45 aus zwei Hebeln 46 und 47 verbunden. Der Hebel 47 stützt sich in einer ortsfesten Achse 48 schwenkbar ab, während an einem Verbindungsgelenk 49, das die beiden Hebel 46 und 47 der Kniehebelanordnung 45 miteinander verbindet, eine Kolbenstange 51 eines Arbeitszylinders 52 angelenkt ist. Die Bewegungsrichtung der Kolbenstange 51 ist senkrecht zu der Verschiebebewegung der Schubstange 43, so daß eine Abwärtsbewegung der Kolbenstange 51 zu einem Strecken der Kniehebelanordnung 45 führt, wodurch das Messer 41 in Richtung auf die Drehachse 23 vorgeschoben wird.With the back of the slide 42, a push rod 43 is connected, which is guided in a longitudinally displaceable manner in a bushing 44. The displacement movement is perpendicular to the axis of rotation 23. A toggle lever arrangement 45 comprising two levers 46 and 47 is connected to the rear end of the cylindrical push rod 43. The lever 47 is pivotably supported in a fixed axis 48, while a piston rod 51 of a working cylinder 52 is articulated on a connecting joint 49, which connects the two levers 46 and 47 of the toggle lever arrangement 45 to one another. The direction of movement of the piston rod 51 is perpendicular to the displacement movement of the push rod 43, so that a downward movement of the piston rod 51 leads to a stretching of the toggle lever arrangement 45, whereby the knife 41 is advanced in the direction of the axis of rotation 23.

Auf dem Messer 41 sitzt ein keilförmiger Schieber 53, der mit der jeweils ausgerichteten Nut 27 fluchtet und bei der Schnittbewegung des Messers 41 auf der Schneidmatrize 37 in die Nut 27 fast vollständig eintaucht, ohne jedoch deren Grund oder Ränder 33, 34 bzw. die Erhöhungen 35, 36 zu berühren.On the knife 41 sits a wedge-shaped slide 53, which is aligned with the respectively aligned groove 27 and, when the knife 41 moves on the cutting die 37, is almost completely immersed in the groove 27, but without its base or edges 33, 34 or the elevations 35, 36 to touch.

Mit Hilfe der Schneideinrichtung 14 wird von dem Streifen 15 ein Abschnitt heruntergeschnitten, dessen Länge der Länge der benötigten Verstärkung 9 entspricht. Der Streifen 15 bewegt sich im Gleichstrom zu den Registereinlagen 1. Stromaufwärts von der Schneideinrichtung 14 ist für den Streifen 15 eine Falzstation 54 vorgesehen, die dazu dient, den von einer nicht gezeigten Vorratsspule kommenden bandförmigen Streifen 15, der von einer Umlenkrolle 55 umgelenkt und von einer nachfolgenden Führungseinrichtung 56 plan gehalten wird, in Längsrichtung einmal zu falten. Zu diesem Zweck enthält die Falzstation einen Falzblock 57, durch den die beiden Rändern des Streifens 15 aufeinander zu bewegt werden,sowie zwei Quetschrollen 58, zwischen denen der vorgefaltete Streifen 15 hindurchläuft. Zumindest eine der beiden Quetschrollen 58 ist durch einen nicht veranschaulichten Antrieb gesteuert schrittweise in Umdrehungen zu versetzen, um den gefalteten Streifen 15 durch die Öffnung 38 der Schneidmatrize 37 vorzuschieben.With the aid of the cutting device 14, a section is cut down from the strip 15, the length of which corresponds to the length of the required reinforcement 9. The strip 15 moves in direct current to the register inserts 1. Upstream of the cutting device 14, a folding station 54 is provided for the strip 15, which serves to strip the strip-shaped strip 15 coming from a supply spool, not shown, which is deflected by a deflection roller 55 and from a subsequent guide device 56 is kept plan to fold once in the longitudinal direction. For this purpose contains the folding station a folding block 57, through which the two edges of the strip 15 are moved towards each other, and two pinch rollers 58, between which the pre-folded strip 15 runs. At least one of the two squeezing rollers 58 is to be set in a controlled manner by means of a drive (not shown) in rotation in order to advance the folded strip 15 through the opening 38 of the cutting die 37.

Infolge der Eigenelastizität des Materials für den Streifen 15, vorzugsweise Mylar, springt der gefaltete Streifen 15 im Bereich zwischen den beiden Quetschrollen 58 und der Schneideinrichtung 15 geringfügig wieder auf, damit, wie in Fig. 4 zu sehen ist, das Messer 41 zwischen die beiden durch die Faltung entstandenen Schenkel des Streifens 15 eindringen kann. Hierdurch wird jeder Schenkel des Streifens 15 für sich abgeschnitten, während andererseits zwangsläufig durch die Schnittbewegung der Streifen 15 geöffnet wird. Der entstehende Schnittgrat weist an beiden Schenkeln des Streifens 15 nach außen und behindert nicht das Aufspringen des von dem Streifen 15 heruntergeschnittenen und die Verstärkung 9 bildenden Abschnitts.Due to the inherent elasticity of the material for the strip 15, preferably Mylar, the folded strip 15 jumps open slightly in the area between the two pinch rollers 58 and the cutting device 15, so that, as can be seen in FIG. 4, the knife 41 between the two leg of the strip 15 created by the folding can penetrate. As a result, each leg of the strip 15 is cut off for itself, while on the other hand the strip 15 inevitably opens due to the cutting movement. The resulting cut burr points outward on both legs of the strip 15 and does not hinder the opening of the section cut off from the strip 15 and forming the reinforcement 9.

Damit nach dem Zusammenführen einer Verstärkung 9 mit der entsprechenden Registereinlage 1 die Verstärkung 9 an der Registereinlage 1 an der richtigen Stelle verbleibt, wenn die Registereinlage 1 aus der Trommel 22 wegbewegt wird, ist die Hefteinrichtung 16 vorhanden. Die Hefteinrichtung 16 enthält einen unteren schwenkbar gelagerten Arm 61, dessen Schwenkachse parallel zu der Drehachse 23 verläuft. An dem freien Ende des Armes 61 ist ein Balken 62 angebracht, der parallel zu der Drehachse 23 verläuft und auf seiner Oberseite eine Vielzahl, im gezeigten Ausführungsbeispiel insgesamt fünf, schmale Zinken 63 trägt. Sämtliche Zinken 63 haben an ihrem von dem Balken 62 abliegenden Ende eine plane Andruckfläche 64, die alle auf derselben Höhe liegen. Mit den Zinken 63 fluchtet ein weiterer Satz von Zinken 65, die an einem über der Trommel 22 befindlichen Balken 66 befestigt sind. Der Balken 66 erstreckt sich parallel mit Abstand zu dem Balken 62 und sitzt an einem eigenen Schwenkarm 67, der wiederum um eine zu der Drehachse 23 parallele Schwenkachse ortsfest schwenkbar gelagert ist. Die Zinken 65 haben eine ähnliche Gestalt wie die Zinken 63 und besitzen ebenfalls plane Andruckflächen 68, die auf derselben Höhe liegen.So that after the amalgamation of a reinforcement 9 with the corresponding register insert 1, the reinforcement 9 remains in the correct position on the register insert 1 when the register insert 1 is moved away from the drum 22, the stitching device 16 is present. The stapling device 16 contains a lower pivotably mounted arm 61, the pivot axis of which runs parallel to the axis of rotation 23. At the free end of the arm 61, a bar 62 is attached, which runs parallel to the axis of rotation 23 and on its top a large number, in the embodiment shown carries a total of five, narrow tines 63. All tines 63 have at their end remote from the beam 62 a flat pressure surface 64, which are all at the same height. Another set of tines 65, which are fastened to a bar 66 located above the drum 22, is aligned with the tines 63. The bar 66 extends parallel at a distance from the bar 62 and is seated on its own swivel arm 67, which in turn is mounted so as to be pivotable about a swivel axis parallel to the axis of rotation 23. The tines 65 have a similar shape to the tines 63 and also have flat pressure surfaces 68 which are at the same height.

Damit die Zinken 65 und die Zinken 63 mit der in der Nut 27 befindlichen Verstärkung 9 in Eingriff gebracht werden können, enthält die Trommel 22 in Umfangsrichtung verlaufende Nuten 69, die zahlenmäßig mit der Anzahl der Zinken 63 bzw. 65 übereinstimmen und mit diesen fluchten. Die Nuten 69 durchsetzen bzw. schneiden sämtliche Nuten 27 an dem Umfang 26 der Trommel 22. Mittels einer nicht weiter gezeigten Antriebseinrichtung können die beiden Arme 61 und 67 aufeinander zu geschwenkt werden, was dazu führt, daß die beiden Sätze von Zinken 63, 65 in die Nuten 69 eintauchen, und zwar auf jener Seite der Trommel 22, die der Transporteinrichtung 12 benachbart ist.So that the tines 65 and the tines 63 can be brought into engagement with the reinforcement 9 located in the groove 27, the drum 22 contains circumferential grooves 69 which correspond in number to the number of tines 63 and 65 and are in alignment therewith. The grooves 69 penetrate or cut all the grooves 27 on the circumference 26 of the drum 22. The two arms 61 and 67 can be pivoted towards one another by means of a drive device (not shown further), which leads to the two sets of tines 63, 65 in immerse the grooves 69 on the side of the drum 22 which is adjacent to the transport device 12.

Die Arbeitsweise wird im einzelnen weiter unten beschrieben.The mode of operation is described in detail below.

Die Anschlageinrichtung 17 dient, wie bereits oben erwähnt, dazu, die jeweils mit der Verstärkung 9 zu versehende Registereinlage 1 bezüglich der Längserstreckung der Trommel 22 so anzuhalten, daß der Tab 7 bzw. der nach dem endgültigen Zuschnitt den Tab 7 bildende Bereich mit einer in der entsprechenden Nut 27 liegenden Verstärkung 9 fluchtet. Da mit der beschriebenen Vorrichtung 11 unmittelbar aufeinanderfolgend sämtliche Registereinlagen 1 erzeugt werden, die zu einem kompletten Satz gehören, muß die Anschlageinrichtung 17 in Transportrichtung verstellbar sein, weil bei jeweils zwei unmittelbar aufeinanderfolgenden Registereinlagen 1 der zugehörige Tab 7 eine andere Lage an der Vorderkante 6 des Zuschnittes 2 hat. Wenn beispielsweise ein vollständiger Satz Registereinlagen 1 die Buchstaben des Alphabets in ihrer konventionellen Reihenfolge enthält, wird zunächst die Registereinlage 1 mit dem Buchstaben "Z" mit einer Verstärkung versehen. Die Anschlageinrichtung 17 muß in diesem Falle eine Lage haben, die dafür sorgt, daß der in der Nähe der Unterkante des Zuschnittes 2 befindliche Tab 7 mit der in der Nut 27 der Trommel 22 bereitgehaltenen Verstärkung 9 fluchtet. Der Tab 7 mit dem Buchstaben "Y" wird demgegenüber ein Stück weiter in Richtung auf die Oberkante des Zuschnittes 2 versetzt sein, weshalb die Anschlageinrichtung 17 entsprechend dem Versatz der Tabs 7 in benachbarten Registereinlagen 1 ein Stück weiter stromabwärts verstellt werden muß.As already mentioned above, the stop device 17 serves to stop the register insert 1 to be provided with the reinforcement 9 with respect to the longitudinal extension of the drum 22 in such a way that the tab 7 or the area forming the tab 7 after the final cutting with an in the corresponding groove 27 lying reinforcement 9 is aligned. Since all of the register inserts 1 that belong to a complete set are generated in immediate succession with the described device 11, the stop device 17 must be adjustable in the transport direction, because with two immediately successive register inserts 1 the associated tab 7 has a different position on the front edge 6 of the Blank 2 has. For example, if a complete set of register inserts 1 contains the letters of the alphabet in their conventional order, the register insert 1 is first provided with the letter "Z" with a reinforcement. In this case, the stop device 17 must have a position which ensures that the tab 7 located in the vicinity of the lower edge of the blank 2 is aligned with the reinforcement 9 provided in the groove 27 of the drum 22. In contrast, the tab 7 with the letter "Y" will be offset a little further towards the upper edge of the blank 2, which is why the stop device 17 must be adjusted a little further downstream in accordance with the offset of the tabs 7 in adjacent register inserts 1.

Der Aufbau der Anschlageinrichtung 17 ist nachfolgend anhand der Fig. 5 und 6 im einzelnen erläutert.The structure of the stop device 17 is explained in detail below with reference to FIGS. 5 and 6.

Unterhalb der Transporteinrichtung 12 befinden sich ortsfest angebracht zwei Träger 71, die parallel mit Abstand zueinander in Richtung auf die Transportriemen 21 aufragen. Zwischen den beiden Trägern 71 erstreckt sich an deren Oberseite eine zylindrische Führungsschiene 72, auf der mit einer Kugelführungsbüchse 73 ein Schlitten 74 spielfrei parallel zu der Drehachse 23 geführt ist. Mittels eines nicht weiter gezeigten Zapfens, der in eine Längsnut der Führungsschiene 72 eingreift, ist der Schlitten 74 auf der Führungsschiene 72 drehgesichert. An seinen beiden Seiten ragen zwei an ihm mittels Schrauben 75 befestigte Halter 76 auf, die am oberen freien Ende durch ein Joch 77 miteinander verbunden sind. In dem Joch 77, das mit Abstand über der Oberseite des Schlittens 74 verläuft, ist ein Arbeitszylinder 78 befestigt, dessen Kolbenstange 79 vertikal und damit rechtwinklig zu der Drehachse 23 hin und her verstellbar ist. Das freie Ende der Kolbenstange 79 trägt einen Balken 81, auf dem mehrere, im gezeigten Ausführungsbeispiel insgesamt vier Anschlagbolzen 82 nach oben ragend befestigt sind. Die Anschlagbolzen 82 sitzen in einer Reihe, die rechtwinklig zu der Transportbewegung der Registereinlagen 1 auf der Transporteinrichtung 12 ist.Below the transport device 12 there are two carriers 71 which are fixed in place and which project parallel to one another in the direction of the transport belts 21 at a distance from one another. A cylindrical guide rail 72 extends on the upper side between the two carriers 71, on which a slide 74 is guided parallel to the axis of rotation 23 without play with a ball guide bushing 73. The carriage 74 is secured against rotation on the guide rail 72 by means of a pin (not shown further) which engages in a longitudinal groove of the guide rail 72. Two brackets 76 fastened to it by screws 75 protrude on both sides and are connected to one another at the upper free end by a yoke 77. In the yoke 77, which runs at a distance above the upper side of the slide 74, a working cylinder 78 is fastened, the piston rod 79 of which can be adjusted back and forth vertically and therefore at right angles to the axis of rotation 23. The free end of the piston rod 79 carries a beam 81 on which several stop bolts 82, in the exemplary embodiment shown a total of four, are fastened so as to protrude upwards. The stop bolts 82 sit in a row that is perpendicular to the transport movement of the register inserts 1 on the transport device 12.

Zwei von dem Balken 81 nach unten ragende Stifte 83, die beidseits der Kolbenstange 79 verlaufen, gleiten in Bohrungen des Jochs 77 und dienen als Verdrehsicherung für den Balken 81, um dessen rechtwinklige Lage bezüglich der Transportrichtung der Registereinlagen 1 aufrechtzuerhalten.Two pins 83 projecting downward from the beam 81 and running on both sides of the piston rod 79 slide in bores in the yoke 77 and serve to prevent rotation for the beam 81 in order to maintain its right-angled position with respect to the transport direction of the register inserts 1.

Unterhalb der Führungsschiene 72 erstreckt sich eine Verstärkungsstrebe 84, die endseitig mit den beiden Trägern 71 verschraubt ist. Sie dient u.a. auch der Anbringung eines induktiven Näherungsschalters 90, der ausschließlich in Fig. 6 gezeigt ist und einer nicht veranschaulichten zentralen Steuerung der Vorrichtung 11 mitteilt, wenn der Schlitten 74 eine definierte Lage längs der Führungsschiene 72 eingenommen hat.A reinforcing strut 84 extends below the guide rail 72 and is screwed to the two supports 71 at the end. It also serves the Attachment of an inductive proximity switch 90, which is shown exclusively in FIG. 6 and notifies a central control of the device 11, which is not illustrated, when the slide 74 has assumed a defined position along the guide rail 72.

Zum Bewegen des Schlittens 74 längs der Führungsschiene 72 sitzt an einem der Träger 71 ein Lagerbock 85, in dem mittels zweier Wälzlager 86 eine Antriebswelle 87 drehbar gelagert ist. Der Lagerbock 85 befindet sich unterhalb der Verstärkungsstrebe 84.To move the carriage 74 along the guide rail 72, a bearing block 85 is seated on one of the carriers 71, in which a drive shaft 87 is rotatably mounted by means of two roller bearings 86. The bearing block 85 is located below the reinforcing strut 84.

Mit der Antriebswelle 87 ist drehfest eine Zahnriemenscheibe 88 verbunden, um die ein Zahnriemen herumläuft, der der Übersichtlichkeit halber nicht dargestellt ist und der mit dem Schlitten 74 fest verbunden ist. Die dazu notwendigen Umlenkeinrichtungen im Bereich der beiden Träger 71 sind ebenfalls der Übersichtlichkeit halber weggelassen.A toothed belt pulley 88 is connected in a rotationally fixed manner to the drive shaft 87, around which a toothed belt runs, which is not shown for the sake of clarity and which is firmly connected to the slide 74. The deflection devices necessary for this in the area of the two supports 71 are likewise omitted for the sake of clarity.

Seitlich neben dem Lagerbock 85 befindet sich schließlich angeflanscht ein Schrittmotor 89, dessen Ausgangswelle 91 über eine Ausgleichskupplung 92 mit der Welle 87 verbunden ist. Der Schrittmotor 89 ist ebenso wie der Lagerbock 85 nur in Fig. 6 gezeigt.Flanged to the side next to the bearing block 85 is a stepper motor 89, the output shaft 91 of which is connected to the shaft 87 via a compensating coupling 92. The stepper motor 89, like the bearing block 85, is only shown in FIG. 6.

Die insoweit beschriebene Vorrichtung 11 arbeitet wie folgt, wobei angenommen wird, daß die Trommel 22 die in Fig. 2 gezeigte Stellung hat und in der Nut 27, die unmittelbar in Richtung auf die Transporteinrichtung 12 weist, eine Verstärkung 9 eingelegt ist. In dieser Stellung wird die Trommel 22 durch die zugehörige Antriebseinrichtung 32 festgehalten. Mit Hilfe der Transporteinrichtung 12 kann auf den Transportriemen 21 durch Ingangsetzen der Antriebseinrichtung 19 ein Zuschnitt 2 herantransportiert werden, und zwar so, daß seine Vorderkante 6 parallel zu der Drehachse 23 durch die entsprechende Nut 27 hindurch bewegt wird. Die Transportbewegung des Zuschnittes 2 wird angehalten, sobald er mit seiner Unterkante an den Anschlagbolzen 82 der Anschlageinrichtung 17 anstößt. In dieser Stellung fluchtet derjenige Bereich an der Vorderkante 6 des Zuschnittes 2, in dem sich die Bedruckung des Tabs 7 befindet, mit der in dieser Nut befindlichen Verstärkung 9. Das Eintauchen der Vorderkante 6 in die Nut 27, die die darin enthaltene Verstärkung aufweist, zeigt Fig. 3 in einer Vorderansicht.The device 11 described so far operates as follows, assuming that the drum 22 has the position shown in FIG. 2 and a reinforcement 9 is inserted in the groove 27 which points directly in the direction of the transport device 12. In this position, the drum 22 is held by the associated drive device 32. With the help of the transport device 12, a blank 2 can be transported onto the transport belt 21 by starting the drive device 19, in such a way that its front edge 6 is moved parallel to the axis of rotation 23 through the corresponding groove 27. The transport movement of the blank 2 is stopped as soon as it hits the stop bolt 82 of the stop device 17 with its lower edge. In this position, the area on the front edge 6 of the blank 2 in which the printing of the tab 7 is located is aligned with the reinforcement 9 located in this groove. The immersion of the front edge 6 in the groove 27, which has the reinforcement contained therein, 3 shows a front view.

Durch die zentrale Steuerung der Vorrichtung 11 werden nun die Antriebseinrichtungen zum Verschwenken der beiden Arme 61 und 67 der Hefteinrichtung 16 in Gang gesetzt. Die Balken 62 und 66 mit den beiden Sätzen von Zinken 63, 65 werden aufeinander zu bewegt, wobei sie von oben und von unten her in die in Umfangsrichtung verlaufenden Nuten 69 eintauchen. Sie berühren gleichzeitig die in der Nut 27 befindliche V-förmig gefaltete Verstärkung 9 und pressen sie mit Hilfe ihrer Andruckflächen 64, 68 an mehreren Stellen gegen die Vorder- und die Rückseite des Zuschnittes 2. Dabei wirkt jeweils eine Andruckfläche 64 gleichsam als Amboß für die damit korrespondierende andere Andruckfläche 68 bzw. umgekehrt. Durch die hierdurch hervorgerufene Andruckkraft wird die Verstärkung 9, wie Fig. 7 stark schematisiert zeigt, an mehreren Stellen 92 an der Vorder- und der Rückseite des Zuschnittes 2 angeheftet. Die Art des Anheftens richtet sich dabei danach, wie die entsprechende Rückseite der Verstärkung 9 bzw. des Streifens 15 ausgerüstet ist. Mit Vorzug wird hier ein hitzeaktivierbarer Kleber verwendet, weshalb die Zinken 63 und 65 beheizt sind.By means of the central control of the device 11, the drive devices for pivoting the two arms 61 and 67 of the stitching device 16 are started. The bars 62 and 66 with the two sets of tines 63, 65 are moved towards one another, immersing them in the circumferential grooves 69 from above and below. They simultaneously touch the V-shaped reinforcement 9 located in the groove 27 and press them with the help of their pressure surfaces 64, 68 at several points against the front and the back of the blank 2. Each pressure surface 64 acts as an anvil for the corresponding other pressure surface 68 or vice versa. The resulting pressing force causes the reinforcement 9 to be attached to the front and rear of the blank 2 at several points 92, as shown in a highly schematic manner in FIG. 7. The type of attachment depends on how the corresponding back of the reinforcement 9 or the strip 15 is equipped. A heat-activated adhesive is preferably used here, which is why the tines 63 and 65 are heated.

Nach dem erfolgten Anheften der Verstärkung 9 an dem Zuschnitt 2 werden die beiden Schwenkarme 61 und 67 wieder voneinander wegbewegt, was die Zinken 63 und 65 aus den Nuten 69 auftauchen läßt. Daraufhin wird der Druckmittelzylinder 78 angesteuert, und zwar wird seine kolbenstangenseitige Zylinderkammer mit einem Druckfluid beaufschlagt. Die Kolbenstange 79 bewegt sich in den Druckmittelzylinder hinein und zieht die Anschlagstifte 82 unter die von den beiden Transportriemen 21 definierte Ebene. Die Anschlagstifte 82 gelangen so aus dem Weg des Zuschnittes 2 heraus, der beim Ingangsetzen der Transporteinrichtung 12 aus der Nut 27 der Trommel 22 herausbewegt wird.After the reinforcement 9 has been attached to the blank 2, the two pivot arms 61 and 67 are moved away from one another again, which causes the prongs 63 and 65 to emerge from the grooves 69. Thereupon, the pressure medium cylinder 78 is actuated, namely its cylinder chamber on the piston rod side is pressurized with a pressure fluid. The piston rod 79 moves into the pressure medium cylinder and pulls the stop pins 82 below the plane defined by the two transport belts 21. The stop pins 82 thus come out of the path of the blank 2, which is moved out of the groove 27 of the drum 22 when the transport device 12 is started.

Während auf der einen Seite der Trommel eine Verstärkung aus der entsprechenden Nut 27 heraus auf den Zuschnitt 2 überführt wurde, wird auf der diametral gegenüberliegenden Seite die entsprechende Nut 27 mit einer neuen Verstärkung 9 beschickt. Man kann deswegen sagen, daß sich eine der Nuten 27 in der Überführungsstellung befindet, während eine andere Nut 27, die dem Schieber 53 gegegenübersteht, in der Beschickungsstellung ist. Das Beschicken der für die Beschreibung als leer angenommenen Nut 27 geschieht dadurch, daß die Quetschrollen 58 von der zentralen Steuerung in Umdrehung versetzt werden. Hierdurch wird einerseits neuer Streifen 15 von der Vorratsrolle abgezogen und kontinuierlich in der Falzstation 54 gefaltet, während der V-förmig gefaltete Streifen 15 von den Andruckrollen 58 durch die Öffnung 38 in der Matrize 37 hindurchgeschoben wird. Obwohl der Streifen 15 durch die beiden Quetschrollen 58 stark gefalzt ist, hat er nach wie vor eine gewisse Tendenz, aufzuspringen, weshalb er mit seinen durch die Falzung entstandenen beiden Schenkeln an den Rändern der Öffnung 38 anliegen wird. Gleichzeitig bekommt er durch die Falzung eine Stabilität gegen Ausknicken und läßt sich ohne weiteres in horizontaler Richtung vorschieben. Da die Öffnung 38 einen größeren radialen Abstand von der horizontal verlaufenden Drehachse 23 hat als die jeweilige Nut 27, kann der Streifen 15 ohne weiteres in die entsprechende Nut 27 eingeschoben bzw. dieser vorgelagert werden.While a reinforcement was transferred from the corresponding groove 27 to the blank 2 on one side of the drum, the corresponding groove 27 is loaded with a new reinforcement 9 on the diametrically opposite side. It can therefore be said that one of the grooves 27 is in the transfer position, while another groove 27, which faces the slide 53, is in the loading position. The loading of the groove 27 assumed to be empty for the description takes place in that the pinch rollers 58 are set in rotation by the central control. In this way, on the one hand, new strip 15 is pulled off the supply roll and continuously folded in the folding station 54, while the V-shaped strip 15 is pushed by the pressure rolls 58 through the opening 38 in the die 37. Although the strip 15 is strongly folded by the two pinch rollers 58, it still has a certain tendency to jump open, which is why it rests on the edges of the opening 38 with its two legs formed by the folding becomes. At the same time, the fold provides stability against buckling and can be easily pushed forward in the horizontal direction. Since the opening 38 is at a greater radial distance from the horizontally running axis of rotation 23 than the respective groove 27, the strip 15 can easily be inserted into the corresponding groove 27 or be placed in front of it.

Nachdem ein der Länge der Verstärkung 9 entsprechendes Stück des Streifens 15 durch die Matrize 37 hindurchgeschoben ist, wird der Antrieb für die Quetschrollen 58 stillgesetzt. Stattdessen wird der Arbeitszylinder 52 in Gang gesetzt, dessen Kolbenstange 51 ausgefahren wird, um die Kniehebelanordnung 45 zu strecken. Dadurch wird das Messer 41 in Richtung auf die Drehachse 23 vorgeschoben, wobei die Spitze des dreieckförmigen Messers 41, wie unschwer Fig. 4 erkennen läßt, in den von dem gefalteten Streifen 15 begrenzten Zwickelbereich zwischen die beiden Schenkel einfährt. Jeder der beiden Schenkel wird für sich von dem Messer 41 an den Kanten der Öffnung 38 abgeschnitten.After a piece of the strip 15 corresponding to the length of the reinforcement 9 has been pushed through the die 37, the drive for the pinch rollers 58 is stopped. Instead, the working cylinder 52 is started, the piston rod 51 of which is extended in order to stretch the toggle lever arrangement 45. As a result, the knife 41 is advanced in the direction of the axis of rotation 23, the tip of the triangular knife 41, as can easily be seen in FIG. 4, entering the gusset area delimited by the folded strip 15 between the two legs. Each of the two legs is cut off by the knife 41 at the edges of the opening 38.

Gleichzeitig mit dem Abschneiden durch das Messer 41 wird auch der daran sitzende, im Querschnitt keilförmige Schieber 53 auf die Nut 27 zu bewegt. Der über die Matrize 37 hinausstehende Abschnitt des Streifens 15 wird von dem Schieber 53 erfaßt und zwangsweise in die Nut 27 eingepreßt. Das Ende der Vorschubbewegung des Messers 41 bzw. des Schiebers 53 liegt erst dann vor, wenn die der Trommel 22 benachbarte Kante des Schiebers 53 fast an dem Grund der Nut 27 anstößt. In dieser Stellung haben mit Sicherheit die Ränder des mittlerweile von dem Streifen 15 vollständig abgeschnittenen Abschnittes, der jetzt die Verstärkung 9 bildet, die Erhöhungen 36 und 37 passiert. Die V-förmig gefaltete Verstärkung 9 springt infolge ihrer Eigenelastizität noch ein Stück weit auf und ihre Ränder werden sich beim Zurückweichen des Schiebers 53, wenn der Druckmittelzylinder 52 in umgekehrter Richtung gefüllt wird, hinter den Erhöhungen 35, 36 verhaken. Um dies zu erreichen, muß die Breite des Streifens 15 vor der Faltung in der Falzstation 54 kleiner oder höchstens genauso groß sein wie der kürzeste Weg durch die Nut 27 entlang ihrer beiden Wände 28, 29, d.h. so lang wie die Summe der in der Draufsicht von Fig. 3 erkennbaren Linien, die die Seitenwände 28 und 29 einer Nut 27 repräsentieren.Simultaneously with the cutting by the knife 41, the slider 53 seated thereon, which is wedge-shaped in cross section, is also moved towards the groove 27. The section of the strip 15 which projects beyond the die 37 is gripped by the slide 53 and is forcibly pressed into the groove 27. The end of the advancing movement of the knife 41 or of the slider 53 is only present when the edge of the slider 53 adjacent to the drum 22 abuts almost on the base of the groove 27. In this position, the edges of the section which has now been completely cut off from the strip 15 and which now forms the reinforcement 9 have passed the ridges 36 and 37. The V-shaped reinforcement 9 jumps due to its inherent elasticity a little further and their edges will catch behind the ridges 35, 36 when the slide 53 retracts, when the pressure cylinder 52 is filled in the opposite direction. To achieve this, the width of the strip 15 before folding in the folding station 54 must be smaller or at most as large as the shortest path through the groove 27 along its two walls 28, 29, ie as long as the sum of those in the plan view 3 recognizable lines, which represent the side walls 28 and 29 of a groove 27.

Die Verstärkung 9 ist somit in der betreffenden Nut 27 gefangen und kann in Richtung des Schlitzes der Nut 27 nur herausgenommen werden, wenn sie entsprechend zusammengedrückt wird.The reinforcement 9 is thus caught in the groove 27 in question and can only be removed in the direction of the slot of the groove 27 if it is compressed accordingly.

Nach erfolgter Vor- und Zurückbewegung des Messers 41 und damit auch des Schiebers 53 ist eine anfangs leere Nut 27 mit einer neuen Verstärkung 9 beschickt, während andererseits zeitlich zusammenfallend mit diesem Zyklus, wie oben beschrieben, auf der gegenüberliegenden Seite der Trommel 22 eine vorher in der Nut 27 befindliche Verstärkung 9 auf dem entsprechenden Zuschnitt 2 angeheftet und durch die Weiterbewegung des Zuschnittes 2 aus der Nut 27 entfernt wurde.After the forward and backward movement of the knife 41 and thus also the slider 53, an initially empty groove 27 is loaded with a new reinforcement 9, while on the other hand coinciding with this cycle, as described above, on the opposite side of the drum 22 one beforehand the reinforcement 9 located in the groove 27 has been attached to the corresponding blank 2 and has been removed from the groove 27 by the further movement of the blank 2.

Ehe der nachfolgende Zuschnitt 2 in den Bereich der Überführungseinrichtung bzw. der Trommel 22 gelangt, muß zunächst die Trommel 22 durch die Antriebseinrichtung 32 um einen dem Abstand zwischen zwei Nuten 27 entsprechenden Winkel weitergedreht werden, beispielsweise in Richtung eines in Fig. 2 sichtbaren Pfeiles 93, wodurch eine mit einer Verstärkung 9 beschickte Nut 27 in den Weg der Zuschnitte 2 gelangt, während gleichzeitig eine leere Nut 27 in die Beschickungsstellung gegenüber dem Schieber 53 gebracht wird.Before the subsequent blank 2 reaches the area of the transfer device or the drum 22, the drum 22 must first be rotated further by the drive device 32 by an angle corresponding to the distance between two grooves 27, for example in the direction of an arrow 93 visible in FIG. 2 , whereby a groove 27 loaded with a reinforcement 9 gets into the path of the blanks 2 while at the same time an empty groove 27 is brought into the loading position opposite the slide 53.

Bei der gewählten Ausführungsform sind die an der sichtbaren Oberseite der Trommel 22 laufende Nuten 27 leer, d.h. sie enthalten keine Verstärkungen 9, während die an der Unterseite wandernden Nuten 27 Verstärkungen 9 enthalten, also gefüllt sind.In the selected embodiment, the grooves 27 running on the visible top of the drum 22 are empty, i.e. they contain no reinforcements 9, while the grooves 27 migrating on the underside contain reinforcements 9, that is to say they are filled.

Zusätzlich zu dem Weiterschalten der Trommel 22 um eine Nut 27 muß auch die Anschlageinrichtung 17 verstellt werden, da bei aufeinanderfolgenden Zuschnitten 2 der Tab 7 eine andere Stellung längs der Vorderkante 6 hat.In addition to advancing the drum 22 by a groove 27, the stop device 17 must also be adjusted, since with successive cuts 2 the tab 7 has a different position along the front edge 6.

Bei Vorrichtungen dieser Art werden die Registereinsätze, die einen vollständigen Satz bilden, unmittelbar aufeinanderfolgend produziert. Infolge des Stapelns eines Satzes wird üblicherweise mit derjenigen Registereinlage 1 begonnen, die im fertigen Satz die unterste Registereinlage bildet. Bei einem von "A" bis "Z" durchlaufend gekennzeichneten Satz von Registereinlagen 1 wird also mit dem Buchstaben "Z" begonnen, während die letzte produzierte Registereinlage des betreffenden Satzes den Tab 7 mit dem Symbol "A" enthält. Demzufolge muß die Anschlageinrichtung 17 beim Arbeiten innerhalb eines Satzes beim gewählten Ausführungsbeispiel zunehmend weiter von der die Trommel 22 weg, also in Transportrichtung der Zuschnitte 2 verstellt werden. In jedem Falle muß sichergestellt sein, daß der jeweilige Zuschnitt 2 von der Anschlageinrichtung 17 dann angehalten wird, wenn sein Tab 7 , dessen Lage vom aufgedruckten Symbol abhängig ist, mit der in der Trommel 22 befindlichen Verstärkung 9 fluchtet.In devices of this type, the register inserts, which form a complete set, are produced in immediate succession. As a result of the stacking of a set, the register insert 1 which forms the lowest register insert in the finished set is usually started. In the case of a set of register inserts 1 which is continuously marked from "A" to "Z", the letter "Z" is thus started, while the last register insert produced in the set in question contains tab 7 with the symbol "A". Accordingly, the stop device 17 when working within a set in the selected exemplary embodiment must be moved further and further away from the drum 22, that is to say in the transport direction of the blanks 2. In any case, it must be ensured that the respective blank 2 is stopped by the stop device 17 when its tab 7, the position of which depends on the printed symbol, is aligned with the reinforcement 9 located in the drum 22.

Hierzu wird der Schrittmotor 89 in Gang gesetzt, der über den nicht gezeigten Zahnriemen den Schlitten 84 entsprechend dem Abstand zweier Tabs 7 in benachbarten Registereinsätzen 1 ein Stück weiter von der Trommel 22 wegbewegt. Unter Abstand ist hierbei diejenige Entfernung gemeint, die gemessen werden kann, wenn zwei Registereinlagen 1 mit aufeinanderfolgenden Symbolen deckungsgleich übereinandergelegt werden.For this purpose, the stepper motor 89 is started, which, via the toothed belt (not shown), moves the slide 84 a little further away from the drum 22 in accordance with the distance between two tabs 7 in adjacent register inserts 1. The distance here means the distance that can be measured when two register inserts 1 with successive symbols are superimposed on one another.

Sobald die Position des Schlittens 74 für die nächstfolgende Registereinlage 1 erreicht ist, wird der Schrittmotor 89 stillgesetzt. Der Schlitten 74 bleibt stehen und es wird der Druckmittelzylinder 78 im Sinne eines Aufwärtsbewegens des Balken 81 in Gang gesetzt. Dadurch kommen die Anschlagstifte 82 in den Bewegungsweg der Zuschnitte 2. Jetzt kann die Transporteinrichtung 12 eingeschaltet werden, um den nächsten Zuschnitt, aus dem die nachfolgende Registereinlage 1 entstehen soll, in die Zuführeinrichtung 13 zu bringen. Der Zuschnitt 2 wird lagerichtig angehalten in dem Sinne, daß sein später den Tab 7 bildender Bereich auf die in der Trommel 22 bereitgehaltene Verstärkung 9 ausgerichtet ist, womit die Vorrichtung 11 denselben Zustand eingenommen hat wie am Anfang der Erläuterung ihrer Funktion.As soon as the position of the carriage 74 for the next register insert 1 is reached, the stepper motor 89 is stopped. The carriage 74 stops and the pressure medium cylinder 78 is started in the sense of an upward movement of the beam 81. As a result, the stop pins 82 come into the path of movement of the blanks 2. The transport device 12 can now be switched on in order to bring the next blank, from which the subsequent register insert 1 is to be made, into the feed device 13. The blank 2 is held in the correct position in the sense that its area which later forms the tab 7 is aligned with the reinforcement 9 provided in the drum 22, with which the device 11 has assumed the same state as at the beginning of the explanation of its function.
