Description

Vorrichtung zum Kräuseln dünner Gummiplatten. Bei der Herstellung von Plissees und Rüschen an dünnen Gummiplatten (Gummihaut) wurde bisher ein vorvulkanisierter, unter Zug stehender Träger benutzt, bei dessen Entspannung die darauf gewälzte Platte in Falten gelegt wird. Die Erfindung bezieht sich auf eine Vorrichtung, mit deren Hilfe die Kräuselung der Gummiplatte ohne einen Hilfsträger bewirkt werden kann. Die Erfindung besteht darin, daß zwei Walzen mit verschiedener Umfangsgeschwindigkeit im entgegengesetzten Drehsinn umlaufen, zwischen denen die Gummiplatten hindurchgeführt werden. Die Zeichnung zeigt eine Ausführungsform in Seiten- und Vorderansicht. Die beiden Walzen a, c werden durch Druck in Richtung der Pfeile D aufeinandergepreßt und derart angetrieben, daß die Umfangsgeschwindigkeiten U und Ui verschieden sind, so daß eine Friktion in der zwischen den Walzen hindurchgeführten Platte entsteht, dadurch wird das Kräuseln bewirkt.Device for curling thin rubber sheets. In the preparation of of pleated blinds and ruffles on thin rubber sheets (rubber skin) was previously vulcanized, under tension used carrier, when it relaxes the plate rolled on it is laid in folds. The invention relates to a device with which Help the crimping of the rubber sheet can be effected without an auxiliary carrier. The invention consists in that two rollers with different peripheral speeds rotate in the opposite direction, between which the rubber plates are passed will. The drawing shows an embodiment in side and front view. the Both rollers a, c are pressed against one another by pressure in the direction of the arrows D. and driven in such a way that the peripheral speeds U and Ui are different, so that there is friction in the plate passed between the rollers, this causes the curling.
