A METHOD OF FURTHER INSERTING A PARTIALLY INSERTED LEADING AND/OR TRAILING EDGE OF A PRINTING PLATE INTO RESPECTIVE LOCK-UP SLOTS IN A PLATE CYLINDER OF A PRINTING PRESS

摘要

A method of further inserting a partially inserted leading and/or trailing edge (8a, 8b) of a printing plate (8) into respective lock-up slots (9, 10) in a plate cylinder (2) of a printing press (1) to allow register slots in said edges to engage with lateral pins or a register mechanism in said lock-up slots is disclosed. The method comprises the step of positioning a pushing element (13) relative to the curved surface of the plate cylinder (2), on which a printing plate (8) is disposed with its leading and/or trailing edges (8a, 8b) partially inserted into their respective lock-up slots (9, 10), such that said pushing element (13) will engage and push a raised portion of said printing plate (8), adjacent to said partially inserted leading and/or trailing edge (8a, 8b), down onto the surface of the plate cylinder (2) and the leading and/or trailing edge (8a, 8b) further into their respective lock-up slots, as said plate cylinder (2) rotates.
