Description

In die Gummitücher der Rotationspressen für lithographischen Druck hat man gelochte Metallplatten eingebettet, um einerseits dem Werfen vorzubeugen, das durch, die ungleichmäßige Spannung beim Aufziehen des Tuches auf den Zylinder leicht entsteht, und anderseits, um das Schrumpfen während des Dr ukkes zu verhüten.The rubber blankets of the rotary presses for lithographic printing have been punched Metal plates embedded, on the one hand to prevent the throwing through, the uneven Tension easily arises when pulling the cloth onto the cylinder, and on the other hand, to prevent shrinkage during pressing.

Die Erfindung bezieht sich dagegen auf Kautschukhochdruckformen, und zwar will sie deren Verhalten im Herstellungsgang beeinflussen, um Verzerrungen bei der Anfertigung zu verhüten. Diesem erfindungsgemäßen Zweck dient das Einbetten und Einvulkanisieren eines gegebenenfalls perforierten Metallbleches in den Kautschuk. Bei Anwendung einer solchen Einlage findet bei der* Herstellung der Kautschukhochdruckform kein Schrumpfen in der Plattenebene, sondern höchstens «ine solche in der Plattenhöhe statt, die aber die Genauigkeit des Reliefs, d. i. das Passen, nicht schädigt.The invention, on the other hand, relates to high-pressure rubber molds, and indeed wants to influence their behavior in the production process to avoid distortions during manufacture to prevent. Embedding and vulcanization serve this purpose according to the invention an optionally perforated metal sheet in the rubber. When using such an insert takes place in the * production the high-pressure rubber mold does not shrink in the plane of the plate, but rather at most in the height of the plate, but the accuracy of the relief, d. i. fitting, not harming.

Das Vereinigen der Metallplatte mit dem Kautschuk geschieht z. B. auf folgende Weise: Eine Platte unvulkanisierten Kautschuks wird auf eine perforierte Metallplatte gelegt, und dann werden diese beiden Platten auf der Matrize durch Vulkanisieren miteinander verbunden. Alsdann bildet die perforierte Metallplatte die Basis der Kautschukdruckplatte, in deren Rücken sie durch das Vulkanisieren eingelassen ist.The combining of the metal plate with the rubber is done, for. B. in the following way: A sheet of unvulcanized rubber is placed on a perforated metal plate, and then these two plates are connected to one another on the die by vulcanizing. The perforated metal plate then forms the base of the rubber pressure plate, in the back of which it is vulcanized is let in.

Zufriedenstellende Ergebnisse werden auch erzielt durch Einbetten einer gelochten Zinkplatte in halber Höhe der Kautschukplatte. Dazu verwendet man zwei unvulkanisierte Kautschukplatten, zwischen die man die Metallplatte legt, worauf das Ganze vulkanisiert wird.Satisfactory results are also obtained by embedding a perforated zinc plate halfway up the rubber plate. To do this, two unvulcanized rubber plates are used, between which the metal plate is placed lays on what the whole thing is vulcanized.
