Device for drawing a printing plate onto the plate cylinder of a printing machine

摘要

A device for drawing a printing plate onto a plate cylinder of a printing machine is disclosed. In order to precisely position the folding strip relative to the printing cylinder during the drawing-on procedure, the folding strip of the device is provided with two pairs of adjustable stops. When inserting the printing plate into the clamping rail, a pair of adjustable clamping stops position the folding strip relative to the plate cylinder so that the leading edge of the printing plate is precisely aligned with the clamping rail. On the other hand, when inserting the printing plate into the tension rail, a pair of tensioning stops position the folding rail relative to the plate cylinder so that the trailing edge of the printing plate is bent to the precise angle necessary for its introduction into the tension rail.
