Abstract (en)

A rail-like insert (20) extends over the width of the rubber blanket cylinder (1) and joins the ends (11,13) of the rubber blanket (30). One (13) of the ends has a fixture element (32) possessing a barb (33a,b). The fixture element is held in a barb-shaped recess (25a,b,c) formed in the slot (22) and tensions and holds the rubber blanket on the cylinder. A positioning or lifting mechanism (100) moves the position of the covering surface (123) of the rail-type insert. The rubber blanket has a first pressure layer (131), a second compressible layer (132) and a third support layer (133). A duct (5) extends from one end to the other of the cylinder.

Abstract (de)

Eine Druckmaschine umfaßt einen Gummituchzylinder (1) mit einem Kanal (5), in dem ein schienenartiger Einsatz (20) befestigt ist. Ein Ende (13) eines auf dem Zylinder (1) zu befestigenden Gummituches (30) weist ein mit Widerhaken (33a,33b) versehenes Befestigungselement (32) auf, welches mit entsprechend ausgebildeten widerhakenförmigen Ausnehmungen (25a-25c) in einem Schlitz (22) des Einsatzes (20) zusammenwirkt. Nachdem das Gummituch (30) fest um den Gummituchzylinder (1) herum gelegt wurde, wird durch Einrasten der Widerhaken (33a,33b) des Befestigungsabschnitts (32) eine feste Spannung des Gummituchs (30) um den Zylinder (1) herum bewirkt. <IMAGE>
