Description

Verfahren zur Herstellung von Filtertiichern, Diaphragmen oder Scheidern, insbesondere fär Akkumulatoren. Als Scheider für elektrische Akkumulatoren haben sich die nach dem Patent ag37oo hergestellten Platten gut bewährt. Sie haben jedoch den Nachteil, daß sie nur in verhältnismäßig geringer Breite hergestellt werden können, da.anderenfalls ein zu großer Block, von dem entsprechend große Scheiben abgeschnitten werden könnten, nicht oder nur ungleichmäßig durch Vulkanisation gehärtet würde. Das Zusammensetzen eines großen Diaphragmas aus den kleinen von dem Block abgeschnittenen Stücken würde aber wegen der benötigten Handarbeit zu kostspielig sein.Process for the production of filter bowls, diaphragms or separators, especially for accumulators. As a separator for electrical accumulators the plates manufactured according to the ag37oo patent have proven themselves well. However, you have the disadvantage that they are only made in a relatively narrow width otherwise a block that is too large, from which correspondingly large slices could be cut, not or only unevenly hardened by vulcanization would. Assembling a large diaphragm from the small ones from the block cut pieces would become too expensive because of the manual labor required be.

Nach der Erfindung lassen sich Diaphragmen derselben Art aber von sehr großen Längen aus einem Stück herstellen. Sie besteht darin, daß abwechselnd Kreisscheiben oder Ringe aus porösem und solche aus härtbarem Stoff zu einem Zylinder aufgeschichtet, der erhaltene Block gehärtet und dann durch ein der Zylinderachse paralleles, in Spiralen um den Zylinder geführtes Messer in lange Bahnen zerschnitten wird, in ähnlicher Weise, wie dies zur Herstellung der Holzfurniere aus einem Holzstumme üblich ist. Durch Verwendung von Messern mit gewelltem Querschnitt kann man ,auch hier die Diaphragmen in -Wellenform erhalten. Statt den porösen " und härtbaren Stoff als Scheiben und Ringe kann -man denselben auch als Quadrate oder Rechtecke zum Aufbau des Blockes benutzen, der nunmehr prismatische Form erhält. Durch ein ebenso wie vorher geführtes Messer werden erst die den eingeschriebenen Zylinder überragenden Teile des Prismas abgeschnitten und der übrigbleibende Zylinder wird nunmehr; wie oben beschrieben, in Bahnen zerlegt.According to the invention, diaphragms of the same type can be used Manufacture very long lengths from one piece. It consists in that alternately Circular disks or rings made of porous and hardenable material to form a cylinder piled up, the obtained block hardened and then through one of the cylinder axis parallel knife, guided in spirals around the cylinder, cut into long strips is used, in a similar way to the production of wood veneers from a wooden stump is common. By using knives with a corrugated cross-section, you can, too here the diaphragms are in -wave shape. Instead of the "porous" and hardenable Fabric as disks and rings can also be used as squares or rectangles use to build the block, which is now prismatic in shape. Through a Just like the previously guided knife, the inscribed cylinders are the first cut off the protruding parts of the prism and the remaining cylinder is now; as described above, broken down into strips.

Claims (1)

PATENT-ANSPRUCH: Verfahren zur Herstellung von Filtertüchern, Diaphragmen oder Scheidern großer Längen, insbesondere für Akkumumulatoren, dadurch gekennzeichnet, daß ein aus abwechselnden Lagen von porösem und härtbarem Stoff in an sich bekannter Weise aufgebauter und gehärteter Block durch ein senkrecht zu den Lagen stehendes, spiralförmiges, um die Mittellinie des Blockes geführtes Messer zerschnitten wird. PATENT CLAIM: Process for the production of filter cloths, diaphragms or separators of great lengths, in particular for accumulators, characterized in that a block that is built up and hardened in a manner known per se from alternating layers of porous and hardenable material is replaced by a block that is perpendicular to the layers, spiral-shaped knife guided around the center line of the block is cut.
