ABSTRACT:
A device for introducing printing plates more simply into the opened gripping region of a tension rail assigned to the print start of a plate cylinder. The device includes an introduction rail extending over the format width of the plate cylinder and adapted to be moved against the outer circumference of the plate cylinder into a specific angular position in the region of the print start. When the introduction rail is so positioned, the front edge of the printing plate may be introduced directly into the gripping region of the print-start tension rail via an introduction face formed on the introduction rail. The outer circumference of the plate cylinder coacts with the introduction face of the introduction rail to define a funnel-shaped region for receiving the front edge of the printing plate just prior to the latter being inserted into the tension rail.
