Method for fixing printing plate on plate cylinder uses positioning cylinder to press plate against plate cylinder and on further movement ensures tension force is generated against draw direction of fixing means to eliminate air bubbles

摘要

The printing plate (3) is pressed by a positioning cylinder (2) in an axially parallel contact line (b) against the plate cylinder (1) and then as the positioning cylinder is dragged opposite the plate cylinder a tension force is generated against the draw direction of the fixing means (7) of the plate cylinder at the front edge (6). Independent claim describes printing machine with plate cylinder (1) having fixing and tension means (7,13) for fixing a printing plate and with at least one positioning cylinder and with device for producing differential speed between cylinder surfaces of plate and positioning cylinder.
