ABSTRACT:
To secure a thin, flexible printing plate (4) on the circumference of a plate cylinder (2, 20) by inserting the ends of the printing plate into two narrow parallel slits, the printing cylinder has a groove (3, 21) cut therein in which an insert strip (5, 23) is located which has an inner guide portion (6, 24) fitting within the groove, and a projecting engagement or separating wall portion (9, 25) which is narrower than the guide portion, the walls of the engagement or separating wall portion defining, together with the walls of the groove, the respective slits (18, 30) in which the ends of the printing plate can be inserted. The strip can be irremovably adhered to the cylinder in the groove, or can be made axially slidable, for example under control of a worm (27) engaging in the teeth, so that the lateral register of the printing plate wrapped about the circumference of the cylinder can be adjusted, the printing plate engaging suitable abutment strips or pins (13, 31) formed on the insert strip.
