A feed assembly is provided which feeds a pressure medium to a cylinder and fixes the cylinder in position, independently of whether or not the pressure medium to be connected is supplied. A feed part can be placed on a feed opening of the cylinder by an actuating element which can be controlled independently of any control of the pressure medium. An outlet of the feed part and the feed opening engage one another and lock the cylinder against rotation.

An apparatus for producing printing plates on a supporting cylinder is provided. Mountings arranged on a frame accommodate a blank printing plate arranged on a supporting cylinder. The supporting cylinder is driven by a motor. The apparatus allows the supporting cylinder to be exposed at an end opposite the motor by its journal together with the mounting accommodating the journal. Thus, the supporting cylinder is capable of being moved away from the frame at one end, which makes it possible to draw the printing plate axially off the supporting cylinder. The apparatus can be used to produce a variety of printing plates, including: a relief printing plate, an off-set printing plate, a sleeve-like printing plate, and a gravure printing plate.
