Abstract
Description
Die Erfindung betrifft eine Bahn für Verpackungs- , Polster zwecke und dergleichen, mit eingearbeiteten Vertiefungen bzw. Erhöhungen.The invention relates to a web for packaging, upholstery purposes and the like, with incorporated recesses or Increases.
Für Verpackungszwecke sind Polsterfolien bekannt, die aus Kunststoffmaterial bestehen. Dieses wird in zwei Bahnen verar beitet und weist geformte Vertiefungen auf. Dabei sind die zwei Folienbahnen miteinander versiegelt oder verschweißt. Durch die Hohlräume entsteht eine Luftfüllung, die zur Pufferung dient. Mit solchen Folien wird Stückgut von ver schiedenen Formen verpackt. Ein Nachteil dieser Polsterfolien besteht in der Verwendung des Kunststoffmaterials, das umwelt belastend ist, da es nicht oder kaum verrottet. Ein weiterer Nachteil ist der hohe Aufwand in der Herstellung, da dieses Verpackungsmaterial meist nur einmal gebraucht und dann weggeworfen wird.Upholstery foils are known for packaging purposes Plastic material exist. This is processed in two lanes works and has shaped depressions. Here are the two sheets of film sealed or welded together. An air filling is created through the cavities Buffering is used. With such films, general cargo from ver packaged in various forms. A disadvantage of these cushion films consists in the use of plastic material that is environmentally is stressful because it does not or hardly rots. Another The disadvantage is the high cost of production, since this Packaging material usually only used once and then is thrown away.
Auch Polystyrolchips, mit denen Hohlräume in Kartons und der gleichen gefüllt werden können, sind umweltbelastend, da sie nicht verrotten und auch in der Herstellung vergleichsweise aufwendig sind.Also polystyrene chips with which cavities in boxes and the same can be polluted because they are polluting do not rot and also comparatively in production are expensive.
Die Verwendung von Papier, Wellpappe und dergleichen für die oben genannten Zwecke befriedigt in vielen Fällen ebenfalls nicht. Insbesondere eignet sich Wellpappe durch die hohe Steifigkeit des Materials nicht für Verpackungsgut mit kleinen Abmessungen.The use of paper, corrugated cardboard and the like for the The above-mentioned purposes are also satisfied in many cases Not. Corrugated cardboard is particularly suitable due to the high Stiffness of the material not for packaging goods with small Dimensions.
Die Erfindung hat es sich deshalb zur Aufgabe gemacht, ein Verpackungsmaterial vorzusehen, das mindestens gleich hantier bar wie die bekannten Materialien ist, aber nach kurzer Zeit verrottet, ohne umweltbelastend zu sein.The invention has therefore set itself the task of a Provide packaging material that is at least the same bar as the known materials, but after a short time rots without polluting the environment.
Die Erfindung geht dazu aus von einer Bahn für Verpackungs-, Polsterzwecke und dergleichen, mit eingearbeiteten Vertie fungen bzw. Erhöhungen und schlägt vor, daß die Bahn aus einem Vlies von Naturfasern, insbesondere Abfallfasern besteht, das mit Bindemitteln versetzt ist, welche die eingeformten Ver tiefungen bzw. Erhöhungen fixieren.The invention is based on a web for packaging, Upholstery and the like, with integrated recess or increases and suggests that the web from a Fleece of natural fibers, in particular waste fibers, that is mixed with binders, which the molded Ver Fix depressions or elevations.
Dabei werden als Fasern vorzugsweise Wolle, Flachs, Jute, Baumwolle, Sisal oder dergleichen verwendet. Insbesondere ist es auch möglich, Abfälle von diesen Fasern zu verwenden die für andere Zwecke nicht mehr verwertbar sind. Das senkt die Herstellungskosten, was insbesondere bei der einmaligen Ver wendung des Materials von Bedeutung ist.The fibers used are preferably wool, flax, jute, Cotton, sisal or the like is used. In particular is it is also possible to use waste from these fibers are no longer usable for other purposes. That lowers them Manufacturing costs, which is particularly the case with the one-off Ver material is important.
Als Bindemittel kommen organische oder anorganische Binde mittel in Frage. Bei den organischen Bindemitteln handelt es sich beispielsweise um Stärke, Harze oder Wachse. Auch diese Bindemittel sind in keiner Weise umweltbelastend und verrotten nach kurzer Zeit. Bei den anorganischen Bindemitteln handelt es sich beispielsweise um synthetische Bindemittel oder auch um Schmelzfasern.Organic or inorganic binders are used as binders medium in question. The organic binders are for example starch, resins or waxes. This too Binders are in no way harmful to the environment and rot after a short time. The inorganic binders it is, for example, synthetic binders or around melt fibers.
Bei der bevorzugten Ausführungsform der Erfindung betragen die Höhenabmessungen der Vertiefungen bzw. Erhöhungen ein Mehr faches der Dicke des Vlieses. Das gibt einen besonders guten Polsterungseffekt, wobei mitwirkt, daß das Vlies beispiels weise im Vergleich zu Papier eine vergleichsweise große Dicke aufweist. Das Material bleibt auch mit den eingeformten Er höhungen geschmeidig und läßt sich auf diese Weise auch um vergleichsweise kleines Verpackungsgut wickeln.In the preferred embodiment of the invention, the Height dimensions of the depressions or elevations a more times the thickness of the fleece. That gives a particularly good one Upholstery effect, which contributes to the fact that the fleece compared to paper a comparatively large thickness having. The material remains with the molded Er increases smooth and can also be done in this way wrap comparatively small packaged goods.
Bei einer Ausführungsform der Erfindung sind in Abständen angeordnete einzelne Erhöhungen vorgesehen. Diese Erhöhungen können beispielsweise in der Draufsicht etwa kreisförmig sein und erlauben eine hohe Geschmeidigkeit des Materials.In one embodiment of the invention are at intervals arranged individual increases provided. These increases can, for example, be approximately circular in plan view and allow a high suppleness of the material.
Bei einer anderen Ausführungsform der Erfindung sind in Ab ständen angeordnete längliche Erhöhungen in verschiedenen Ausrichtungen vorgesehen. Diese Erhöhungen können beispiels weise Zickzackform oder Kurvenform aufweisen, wodurch das Material einerseits Halt bekommt, andererseits aber auch durch die verschiedenen Ausrichtungen der Erhöhungen so biegsam bleibt, daß es sich auch für die Verpackung kleiner Teile ver wenden läßt.In another embodiment of the invention, in Ab arranged elongated elevations in different Alignments provided. These increases can, for example wise zigzag shape or curve shape, which the Material gets hold on the one hand, but also through the different orientations of the ridges so flexible remains that it ver also for the packaging of small parts can turn.
Es hat sich als günstig herausgestellt, wenn die Erhöhungen im Querschnitt eine etwa halbkreisförmige Gestalt aufweisen. Diese Erhöhungen sind leicht herzustellen, beispielsweise durch das Führen des vorbereiteten Vlieses durch ein Kalander walzenpaar, wobei auf einer Kalanderwalze Vorsprünge ange ordnet sind, denen Ausnehmungen auf der anderen Walze ent sprechen. Es können auch Pressen für die Formung benutzt werden.It has turned out to be favorable if the increases in Cross-section have an approximately semicircular shape. These increases are easy to make, for example by guiding the prepared fleece through a calender pair of rollers, with projections on a calender roller are arranged, which recesses on the other roller ent speak. Presses can also be used for molding will.
Andere Ausführungsformen der Erfindung können beispielsweise Erhöhungen aufweisen, die im Querschnitt dreieckförmige oder trapezförmige Gestalt haben.For example, other embodiments of the invention Have elevations that are triangular in cross section or have a trapezoidal shape.
Bei der Herstellung der Bahnen wird erst aus dem Rohstoff ein Vlies gebildet, beispielsweise ein Trockenvlies, also ein aerodynamisches Vlies. Das Vlies kann aber auch durch Kar dierung hergestellt werden. Zur Erhöhung der Stabilität werden beispielsweise zwei Vliesschichten winkelig aufeinander gelegt, die dann beispielsweise durch Nadelung verfestigt werden.When the webs are manufactured, the raw material is only used Fleece formed, for example a dry fleece, so a aerodynamic fleece. The fleece can also by Kar be made. To increase stability for example, two layers of fleece at an angle to one another placed, which then solidified, for example, by needling will.
Entweder bei der Bildung des Vlieses oder anschließend wird ein Bindemittel eingebracht. Bei diesem Bindemittel kann es sich beispielsweise um ein Schmelzbindemittel handeln, das beispielsweise pulverförmig aufgebracht wird. Ebenso wie Schmelzfasern wird dieses Bindemittel durch Erhitzen des Vlieses wirksam gemacht.Either during the formation of the fleece or afterwards introduced a binder. With this binder it can are, for example, a melt binder that for example, is applied in powder form. As well as This binder is melted by heating the melt fibers Fleece made effective.
Es können aber auch Naßbindemittel zur Anwendung kommen, bei spielsweise durch das Eintauchen des Vlieses im Bindemittel oder durch Besprühung.However, wet binders can also be used for example by immersing the fleece in the binder or by spraying.
Als vorteilhaft hat es sich herausgestellt, wenn mehrere Vliese mit Erhöhungen bzw. Vertiefungen aufeinander gelegt und miteinander verbunden sind. Auf diese Weise werden dickere Verpackungsmaterialschichten erreicht und die Hantierung, auch bei der Verpackung größerer Gegenstände, ist verhältnismäßig einfach. Dabei können beispielsweise zwei Vliese mit einzelnen kreisförmigen Erhöhungen so miteinander verbunden werden, daß auf den beiden Oberseiten weitgehend glatte Seiten entstehen. Der Polsterungseffekt erhöht sich auf diese Weise beträcht lich.It has proven to be advantageous if several Fleeces with elevations or depressions placed on top of each other and are interconnected. This way, they become thicker Packing material layers reached and handling, too when packaging larger items is proportionate easy. For example, two nonwovens with individual circular ridges are connected so that largely smooth sides appear on the two upper sides. The cushioning effect increases considerably in this way Lich.
In der Zeichnung sind erfindungsgemäße Ausführungsbeispiele schematisch dargestellt. Es zeigen:Exemplary embodiments according to the invention are shown in the drawing shown schematically. Show it:
Fig. 1 eine Draufsicht auf eine Ausfüh rungsform gemäß der Erfindung, Fig. 1 is a plan view of an exporting approximate shape according to the invention,
Fig. 2 einen Schnitt entlang der Schnittlinie II-II der Fig. 1, Fig. 2 shows a section along section line II-II of Fig. 1,
Fig. 3 eine Draufsicht auf eine weitere Ausführungsform der Erfindung, und Fig. 3 is a plan view of another embodiment of the invention, and
Fig. 4 einen Schnitt entlang der Schnittlinie IV-IV der Fig. 3. Fig. 4 shows a section along the section line IV-IV of FIG. 3.
Die Bahn 1 besteht beispielsweise aus einem Vlies mit in der Draufsicht kreisförmigen Erhöhungen 2, wie in der Fig. 1 gezeigt. Dabei sind die Erhöhungen 2 beim Formen des Vlieses eingeformt und weisen halbkugelige Hohlräume 4 auf. The web 1 consists, for example, of a fleece with circular elevations 2 in plan view, as shown in FIG. 1. The elevations 2 are formed when the fleece is formed and have hemispherical cavities 4 .
Das Vlies weist eine im Vergleich zu PVC, Papier, Alu oder dergleichen größere Dicke auf und ergibt eine bessere Polste rung. Die Erhöhungen 2 können auch dreieck- oder trapezförmige Querschnitte aufweisen.The fleece has a greater thickness than PVC, paper, aluminum or the like and results in better cushioning. The elevations 2 can also have triangular or trapezoidal cross sections.
Die Zwischenräume 5 zwischen den Erhöhungen 2 sind weitgehend eben und ergeben bei der Verwendung von zwei Bahnen 1, die mit den Erhöhungen 2 gegeneinander verbunden werden, eine glatte Oberfläche.The spaces 5 between the elevations 2 are largely flat and, when using two webs 1 which are connected to one another by the elevations 2 , give a smooth surface.
In der Bahn 1 können auch längliche Erhöhungen 3, wie in Fig. 3 gezeigt, vorgesehen werden. Solche länglichen Erhöhungen können, wie gezeigt, etwa zickzackförmig sein, es sind aber auch wellenförmige oder isolierte längliche Erhöhungen möglich. Durch die Ausrichtung der Erhöhungen 3 in ver schiedene Richtungen ergibt sich eine gute Biegbarkeit nach allen Richtungen bei vergleichsweise großem Pufferungseffekt. Die Erhöhungen 3 können, wie im Querschnitt der Fig. 4 gezeigt, beispielsweise etwa trapezförmige Hohlräume 6 ein schließen. Es sind aber auch halbkreisförmige oder dreieck förmige Querschnitte möglich.Elongated elevations 3 , as shown in FIG. 3, can also be provided in the web 1 . Such elongated elevations can, as shown, be approximately zigzag, but wave-shaped or isolated elongated elevations are also possible. By aligning the ridges 3 in different directions, there is good flexibility in all directions with a comparatively large buffering effect. The elevations 3 , as shown in the cross section of FIG. 4, include, for example, approximately trapezoidal cavities 6 . However, semicircular or triangular cross sections are also possible.
Ein weiterer Vorteil der Bahn gemäß der Erfindung ist ihr geringes Gewicht pro Fläche und Einheit bei vergleichsweise hohem Volumen, was sich insbesondere für den Versand günstig auswirkt.Another advantage of the web according to the invention is it low weight per unit area and comparative high volume, which is particularly convenient for shipping affects.
