Abstract (en)

A sheet guide system transfers the sheet to a printing cylinder at the speed of the latter. The sheet guide device (9) has a sheet guide plate and extends directly up to the printing cylinder at a distance and arched to the sheet guide system (2). The sheet guide plate has blower nozzles which produce a blast of air which follows the path of the sheet guide plate and is directed away from the printing cylinder. The sheet guide plate can be formed as the top side of an air box connected to a blow air source.

Abstract (de)

Die Erfindung betrifft eine Bogenleiteinrichtung (9) in der Bogenanlage einer Bogendruckmaschine, bestehend aus einer Schwinganlage (1), die einen auf einem der Schwinganlage vorgeordneten Anlegtisch (5) nach der Vorderkante und Seitenkante ausgerichteten Bogen (14) erfaßt und einem der Schwinganlage nachgeordneten Bogenführungssystem (2) übergibt, welches den Bogen mit mindestens Druckzylindergeschwindigkeit einem nachgeordneten Druckzylinder (4) übergibt, wobei dem Bogenführungssystem Mittel (3) zum beschleunigten Abführen des auf dem Anlegtisch befindlichen Bogens zugeordnet sind. Aufgabe der Erfindung ist es, eine Bogenleiteinrichtung zum beschleunigten Abführen eines Bogens vom Anlegtisch zu schaffen, die mit einfachen Mitteln zu realisieren ist, die Bogen vorglättet und auch bei großformatigen und schnelllaufenden Maschinen sowie bei der Verarbeitung dünner Bedruckstoffe ein effektives Betreiben der Gesamtanlage ermöglicht. Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass in einem Abstand und gewölbt zum Bogenführungssystem (2) sich unmittelbar bis zum Druckzylinder (4) erstreckende, ein Bogenleitblech (10) aufweisende Bogenleiteinrichtung (9) vorgesehen ist, die einen dem Verlauf des Bogenleitblech folgenden, Druckzylinder weggerichteten Blasluftstrom realisieren. <IMAGE>
