摘要

A device for adjusting the oblique register in a clamping device for locking printing plates in an offset printing machine. A clamping bar which opens and closes a gap is oriented for insertion of the front or rear edge of a printing plate at the jacket face of the plate cylinder parallel to the cylinder axis. A centering bolt is secured to the clamping bar and it is oriented radially to the plate cylinder and it extends into the insertion gap. The centering belt has a profile which corresponds to the printing plate. The centering bolt is secured on the one outer region of the clamping device so that a stop being oriented in the circumferential direction of the plate cylinder is adjustably attached on the outer regions o the clamping device in the insertion gap. The position of the stop is adjusted with a device disposed on the plate clamping device.
