Abstract

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Leiten von Bogen in Druckmaschinen, die wahlweise im Schöndruck oder im Schön- und Widerdruck einsetzbar sind und mit denen der Bogen (9) im Schön- und Widerdruckverfahren nach dem Prinzip der Hinterkantenwendung gewendet werden kann, wobei der auf einem Zylinder (4) mit Greifern geführte zu wendende Bogen (9) von einem Bogenübernahmesystem (2,3) einer Wendetrommel (1) erfasst und weitergeführt wird, und der Bogen zum gewendeten Bogen (10) wird, wenn die bisherige Bogenvorderkante nunmehr als Bogenhinterkante eine Bewegungsumkehr erfährt.The invention relates to an apparatus and a method for guiding sheets in printing presses, which can be used either in straight printing or perfecting and with which the sheet (9) can be turned in the perfecting process according to the principle of trailing edge, wherein the guided on a cylinder (4) with grippers to be turned sheet (9) by a sheet transfer system (2,3) a turning drum (1) detected and continued, and the arc to the turned bow (10), if the previous sheet leading edge now as sheet trailing edge experiences a reversal of motion.

Aufgabe der Erfindung ist es, eine Vorrichtung und ein Verfahren zum Leiten von Bogen in Druckmaschinen zu schaffen, mit denen der Bogen nach seiner Bewegungsumkehr sicher geleitet wird.The object of the invention is to provide an apparatus and a method for guiding sheets in printing machines, with which the sheet is passed safely after its reversal of motion.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass im Bereich der Peripherie des Zylinders (4) eine von dem Zylinder separate Leiteinrichtung (7) mit beweglicher Greifereinrichtung angeordnet ist, durch die der gewendete Bogen (10) an seiner Hinterkante erfassbar und führbar ist.

Figure imgaf001
According to the invention the object is achieved in that in the region of the periphery of the cylinder (4) a separate from the cylinder guide (7) is arranged with movable gripper device by which the turned sheet (10) is detectable and feasible at its trailing edge.
