Abstract

A method for fixing a plate (4) to a plate cylinder of a printing machine by means of a plate changer comprises several steps: in a first step, register punches (28) which are introduced into the plate (4) are placed over first register pins (29) which are attached to a plate chute of the plate changer. In a second step, the plate (4) is fixed firmly via a holding device (17) which is fixed to a conveying slide block. In a third step, the conveying slide block together with the fixed plate (4) is moved away from the first register pins (29) in a first direction (31), and free spaces (33) between the register punches (28) and the first register pins (29) are produced.

Description

technical field [0001] The invention relates to a method for fastening a printing plate on a plate cylinder of a printing press by means of a plate changer and to a printing press with a plate cylinder and a plate changer for carrying out the method. Background technique [0002] Document EP 1 138 486 A2 describes a printing press with a printing plate cassette in which printing plates are prepositioned by means of a pre-coupling pin system. The printing plates are released from the cassette for plate replacement by means of the pre-mating pins being pulled back. [0003] Document DE 10 2009 012 147 A1 describes a printing plate supply device having a guide element for a printing plate. The guide element is pivotable from a receiving position for the printing forme into an operating position for feeding the printing forme. The printing plate has in its front edge two receptacles which are brought into contact with the printing plate supply for prepositioning the printing p...
