Device for positioning a flexible printing plate on a form cylinder

摘要

The positioner, for a flexible plate on a carrier cylinder (3) with a lengthwise slit (1) in its shaft, is actuated by a lateral movement of the carrier cylinder beyond a set course by an exterior component fixed to the printing machine frame at one end of the cylinder and a crown cam (14) at the other. The inner edges (12, 13) of the crown cam act as guides for a roller (11) on a mobile base plate. Two other cams are located at the base of the roller shaft slit to control the movement of rollers (15) linked to the base plate.
