Abstract

A suspension system which is used to mount a plate nipping element on the frame of a printing machine is provided. The suspension system includes a setting arrangement adapted to move the nipping element between a position where it is engaged against the circumferential surface of a plate cylinder and a position where the nipping element is disengaged from the plate cylinder after first executing an idle stroke. The suspension system also includes a spring means adapted to support the weight of the nipping element on the frame of the printing machine when the nipping element is disengaged from the plate cylinder. In addition, the setting arrangement and the spring are adapted to allow the disengaged nipping roller to pivot away from the plate cylinder further biasing the spring when an object contacts the nipping element.
