Abstract (en)

The transfer drum has air outlets in the drum's cap(3) so as to form an air cushion between the cap and a sheet of paper to transported. The interior of the transfer drum is supplied with air at excess pressure by an air-supply system (15). The cap has flap (4) sealing off the drum's interior from outside, near the rear edge (11) of the drum-cap. The other end of the flap is joi to the transfer drum. The flap is movably positioned by means of rollers (6) in a guide (7).

Abstract (de)

Die Erfindung betrifft eine Übergabetrommel mit schwenkbaren Trommelkappen zwischen Druckwerken oder nach Lackierwerken von Bogendruckmaschinen. Aufgabe der Erfindung ist die Schaffung einer flexibel einsetzbaren Übergabetrommel, die mit geringem Umstellaufwand eine für jede zu verarbeitende Materialstärke optimale abschmierfreie Führung von bedruckten oder lackierten Bögen gewährleistet. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Trommelkappe (3) Luftaustrittsöffnungen für den Aufbau eines Luftpolsters zwischen der Trommelkappe (3) und einem zu transportierenden Bogen aufweist, die Übergabetrommel (18) im Trommelinnnenraum durch ein Luftversorgungssystem (15) mit Luftüberdruck beaufschlagbar, der Trommelkappe (3) in Bogenlaufrichtung gesehen im Bereich der Trommelkappen-hinterkante (11) eine den Trommelinnenraum nach außen abschließende Klappe (4) zugeordnet und die Klappe (4) mit dem anderen Ende gelenkig mit der Übergabetrommel (18) verbunden ist. <IMAGE>
