KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Es ist bekannt, Filterkörbe mit überdachten Wanddurchbrechungen· in der Weise herzustellen, daß aus dem vollen Blech in Reihen aneinanderliegende Streifen lippenartig ausgepreßt werden.It is known to manufacture filter baskets with roofed wall openings in such a way that that strips lying next to one another in rows are pressed out of the full sheet like a lip will. Weiterhin ist es bei der Herstellung feiner Siebe aus gelochten Blechen bekannt, die vorgelochten Bleche einem Walz- oder Preßvorgang zu unterwerfen, wodurch das MaterialFurthermore, it is known in the production of fine sieves from perforated metal sheets that the pre-perforated metal sheets are subjected to a rolling or pressing process subject to what the material ίο so weit gedehnt wird, daß sich die Lochungen verengen.ίο is stretched so far that the holes narrow. Bei dem Verfahren nach vorliegender Erfindung werden die Bleche zur Herstellung der Schlitzlochungen zunächst in bekannter Weise lippenartig ausgepreßt, hierauf die Preßlippen in die Blechebene zurückgetrieben und sodann die Blechteile zwischen den Schlitzreihen durch Walzen gestreckt.In the method according to the present invention, the sheets for the production of Slotted perforations are first pressed out like a lip in a known manner, then the press lips driven back into the sheet metal plane and then the sheet metal parts between the rows of slots Rolling stretched. Auf beiliegender Zeichnung sind nach dem Verfahren hergestellte Bleche in den Fig. 1 bis 9 veranschaulicht.In the accompanying drawing, sheets produced by the method are shown in FIGS. 1 to 9 illustrated. Hierbei können die Bleche, wie in Fig. 1 bis 3 in Draufsicht, Seitenansicht und Schnitt dargestellt, einseitig zu Lippen 10 ausgepreßt werden, oder es können die Lippen beiderseitig ausgepreßt werden, wie aus Fig. 4 bis 6 ersichtlich ist, wovon Fig. 4 ebenfalls eine Draufsicht, Fig. 5 eine Seitenansicht und Fig. 6 einen Schnitt darstellt.Here, the sheets, as in Fig. 1 to 3 in plan view, side view and section shown, are pressed on one side to lips 10, or the lips can be on both sides be squeezed out, as can be seen from Fig. 4 to 6, of which Fig. 4 is also one Top view, Fig. 5 is a side view and Fig. 6 is a section. Das Auspressen der Lippen kann hierbei, wie in beiden Fällen angedeutet, stärker oder schwächer erfolgen.The pressing out of the lips can be stronger or stronger, as indicated in both cases done weaker. Die ausgepreßten Platten werden nun einem Walzvorgang unterworfen und dadurch die Lippen in die Blechebene zurückgetrieben,The pressed plates are now subjected to a rolling process and thereby the Lips driven back into the sheet metal plane, wie in Fig. 7 angedeutet ist. Hierbei werden die Schlitze wieder vollständig geschlossen.as indicated in FIG. 7. Here the slots are completely closed again. Hierauf wird das Blech lediglich an den von Lippen oder Lippenreihen freien Teilen, in Fig. 7 mithin in dem mit 16,17 bezeichneten Bereiche, durch Walzen gestreckt, wobei eine Öffnung bzw. Erweiterung der Schlitze stattfindet. Die Größe dieser Aufweitungen kann durch Wiederholung der Walzarbeit oder durch Vergrößerung des Walzdruckes verändert werden.The sheet is then only on the parts free of lips or rows of lips, in Fig. 7 therefore in the area designated by 16,17, stretched by rolling, wherein an opening or widening of the slots takes place. The size of these widenings can can be changed by repeating the rolling work or by increasing the rolling pressure. Das Blech wird dann statt der in Fig. 7 und 8 angedeuteten Schlitze etwas weitere, in Fig. 9 kenntlich gemachte Schlitze erhalten, welche außerordentlich fein sein können, so daß deren Weite 1Z40 mm nicht übersteigt. Das Blech selbst bleibt vollkommen glatt, die Schlitze selbst haben vollkommen gleiche Größe und weisen keinen Grat auf.Instead of the slots indicated in FIGS. 7 and 8, the sheet metal is then obtained somewhat further slots identified in FIG. 9, which can be extremely fine so that their width does not exceed 1 Z 40 mm. The sheet itself remains perfectly smooth, the slots themselves are completely the same size and have no burrs. Derartige Bleche eignen sich deshalb insbesondere für Brunnenfilterrohre, da sie leicht in den Boden eingetrieben werden können, insbesondere auch für Filtrierung salzhaltiger Gewässer, da sie zufolge der gratlosen Herstellung der Schlitze leicht galvanisiert werden können.Such sheets are therefore particularly suitable for well filter pipes because they are light can be driven into the ground, especially for filtration of saline Waters, as they are easily electroplated due to the burr-free production of the slots can.
