Abstract (en)

[origin: US4510868A] To support a cover wrapped about the printing cylinder and prevent oscillations and resonance phenomena from arising when an attachment groove (2, 23) passes along an adjacent cylinder, a filler strip (8) is located within the groove to close off the groove. The filler strip has circumferentially extending fingers (14) which are supported on circumferentially extending fingers (15) projecting circumferentially from within the groove. The filler strip is axially shiftable along the fingers so that the gap between the support fingers (15) can be used to drop the comb fingers (14) on the filler strip radially inwardly, thus retracting the filler strip. The filler strip is preferably retracted by a retracting mechanism such as a slotted guide tube (11) engaging a lifting strip (10) projecting circumferentially from the filler strip. Axial shifting of the filler strip to place the comb fingers of the filler strip above the support fingers (15) projecting from the groove, after raising of the filler strip, to be flush with the cirmcumference of the cylinder is effected by an eccentered positioning drive located, for example, at an end face of the cylinder. The arrangement permits use of rubber blankets which have end portions fitting in a tiny gap between the filler strip and the groove, with the rubber blankets having ends fitting precisely against each other, thus providing an essentially continuous surface to an engaging cylinder.

Abstract (de)

In einer Grube (2;23) eines Gummi- (1) oder Formzylindersist (21) ein radial bewegliches Füllstück (8) angeordnet, das voneinander beabstandete, kammartige Finger (14) aufweist. In der Zylindergrube (2;23) sind korrespondierende, fest positionierte Finger (15) angeordnet. In einer ersten axialen Position kann das Füllstück (8) abgesenkt werden, so daß eine aufzuspannende Druckform (22) oder ein Gummituch (3) mit seinen Enden (5;24,25) in der Grube fixiert werden kann. Anschließend wird durch eine Hebehilfe (11) das Füllstück (8) radial nach außen gefahren, bis die Grube geschlossen, d.h. abgedeckt ist. Durch eine Axialverschiebung des Füllstückes (8) wird erreicht, daß die Finger (14) des Füllstückes oberhalb der in der Grube angeordneten Finger (15) zu liegen kommen, so daß sie sich auf diesen abstützen.
