Abstract

Die erfindungsgemäße Offset-Rollenrotationsdruckmaschine ist für den Einsatz der Sleevetechnologie konzipiert, wobei auf die Gummizylinder (2, 3) in Axialrichtung hülsenförmige Gummitücher (4, 6) aufschiebbar sind. Auf die Plattenzylinder (10, 11) werden in herkömmlicher Weise endliche Druckplatten aufgelegt, deren Enden in Schlitzen (12, 13) der Plattenzylinder (10, 11) fixierbar sind. Erfindungsgemäß werden Gummizylinder (2, 3) eingesetzt, die einen doppelten Umfang aufweisen, während die Plattenzylinder (10, 11) einen einfachen Umfang aufweisen. Dadurch wird die Steifigkeit des Zylindersystems wesentlich erhöht, so dass bei breiten Maschinen über 1400 mm ein stabiler Bahnlauf und registerhaltiger Druck möglich ist, ohne dass Modifikationen an den Zylindern vorgenommen werden müssen oder die Kompressibilität oder Dicke der Gummischichten der Sleeves in axialer Richtung verändert werden muss.

Figure imgaf001
The offset web-fed rotary printing press according to the invention is designed for the use of the sleeve technology, wherein sleeve-shaped blankets (4, 6) can be pushed onto the blanket cylinders (2, 3) in the axial direction. On the plate cylinder (10, 11) finite pressure plates are placed in a conventional manner, the ends of which in slots (12, 13) of the plate cylinder (10, 11) are fixable. According to the invention rubber cylinders (2, 3) are used, which have a double circumference, while the plate cylinder (10, 11) have a simple circumference. As a result, the rigidity of the cylinder system is significantly increased, so that in wide machines over 1400 mm stable web travel and register-pressure is possible without modifications to the cylinders must be made or the compressibility or thickness of the rubber layers of the sleeves must be changed in the axial direction ,
