Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Vermeiden von Schwingungen in Bogendruckmaschinen mit einem Gegendruckzylinder, dem zur Übertragung eines Druckbildes auf einen Bogen mindestens ein Gummizylinder zugeordnet ist, der mit dem Gegendruckzylinder einen Druckspalt bildet, wobei der Achsabstand zwischen dem Gegendruckzylinder und dem Gummizylinder zur Anpassung an die zur Verarbeitung gelangende Materialdicke durch eine Druckbeistellung veränderbar ausgeführt ist.The The invention relates to a method and a device for avoiding of vibrations in sheet-fed printing machines with an impression cylinder, for transmission associated with a print image on a sheet at least one blanket cylinder is that forms a pressure gap with the impression cylinder, wherein the center distance between the impression cylinder and the rubber cylinder for adaptation to the material thickness to be processed a Druckbeistellung is made changeable.
Eine
Einrichtung zum Einstellen des Achsabstandes zwischen einem Gegendruckzylinder
und einem Gummizylinder sowie zwischen dem Gummizylinder und einem
Plattenzylinder ist aus der
Aufgabe der Erfindung ist es, ein Verfahren und eine Einrichtung zu entwickeln, mit denen eine qualitätsgerechte Verarbeitung unabhängig von der eingestellten Druckpressung möglich ist.task The invention is to develop a method and a device, with whom a quality Processing independent from the set pressure is possible.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren nach den Merkmalen des Anspruchs 1 und eine Einrichtung nach den Merkmalen des Anspruchs 3 gelöst.According to the invention Task by a method according to the features of claim 1 and a device according to the features of claim 3 solved.
Durch die erfindungsgemäße Lösung ist es möglich, die zum Übertragen des Druckbildes erforderliche Druckpressung zwischen den zu bedruckenden Bogen und dem Gummizylinder nach der Übertragung des Druckbildes zu reduzieren und damit den beim Herauslaufen des Bogenendes aus dem Druckspalt auftretenden Stoß zu minimieren. Damit werden Schwingungen des Gummizylinders und so Störungen bei der Farbübernahme vom Plattenzylinder vermieden.By the solution according to the invention it is possible the one to transfer the printing image required printing pressure between the to be printed Sheet and the blanket cylinder after the transfer of the printed image to reduce and thus the running out of the bow end the pressure gap occurring impact too minimize. This will cause vibrations of the blanket cylinder and so on disorders in the color transfer avoided by the plate cylinder.
