Lateral registration device having insertion strips and register pins

An adjustment device adapted to accomplish lateral registration of at least first and second flexible printing plates having ends, said adjustment device comprising:

• a printing cylinder having a peripheral surface extending in a circumferential direction of said printing cylinder, and a printing plate end insertion slit extending in an axial direction of said printing cylinder, the at least first and second printing plates adapted to be positioned at the same position in said circumferential direction and spaced from each other in said axial direction on said peripheral surface of said printing cylinder with the printing plate ends of the at least first and second printing plates both in said printing plate end insertion slit;
• at least first and second insertion strips positioned in said printing plate end insertion slit, said at least first and second insertion strips each having a length and width, with side faces extending along said length, said at least first and second insertion strips being located one behind the other in said circumferential direction of said printing cylinder and abutting each other along said side faces, each of said at least first and second insertion strips being independently shiftable in said axial direction in said printing plate end insertion slit to accomplish lateral registration of the corresponding one the first and second printing plates;
• and
• a register pin on each one of said at least first and second insertion strips, each said register pin being receivable in a cooperating register recess in each one of the printing plate ends.
