Abstract (en)

The spoked drum for a sheet turner in a printing press has a sheet holder assembly (8,9) to hold the sheets against the drum and retain the sheets in their forward and rearward areas. The holder is adjustable in the peripheral direction of the drum. The sheet holder (8) for the front sheet area is mounted on the main drum (12) and the rear sheet holder is mounted on a central axis of the central axis (12) of the drum. The holders are connected by a coupling (18,20).

Abstract (de)

Die Erfindung betrifft eine Speichertrommel in Wendeeinrichtungen von Bogendruckmaschinen. Aufgabe der Erfindung ist es, an einer Speichertrommel in Wendeeinrichtungen die relative Winkellage der Bogenhaltesysteme zueinander mit geringem Aufwand und einfachen Mitteln zu ändern. Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass an der Speichertrommel Bogenhaltesysteme (8, 9) vorgesehen sind zum Erfassen des Bogens (7) im vorderen und hinteren Bereich, die Bogenhaltesysteme (8, 9) in Umfangsrichtung relativ zueinander verstellbar sind, die Bogenhaltesysteme (8) für den vorderen Bogenbereich am Grundkörper (12) und die Bogenhaltesysteme (9) für den hinteren Bogenbereich einer vom Grundkörper (12) aufgenommenen Zentralachse (13) zugeordnet und die Bogenhaltesysteme (8, 9) zueinander durch eine Kupplung (18, 20) miteinander verbunden sind, die mittels Drucköl eines Druck-ölverbandes (29, 30, 31, 32 ) lösbar ist. <IMAGE>
