Abstract
A printing cylinder system for use in a printing press comprising a unique apparatus and method for tensioning and releasing a flexible printing plate that is wrapped around a printing cylinder and clamped by a clamping mechanism disposed within the printing cylinder and accessed by a longitudinal slot. The invention features a mounting mechanism for holding the clamp mechanism in a relative position within the printing cylinder and including control means for moving the clamping mechanism within the printing cylinder substantially toward or away from the cylindrical slot to either apply tension to the printing plate or release tension on the printing plate. In a further embodiment, the invention comprises a piston assembly for pushing the edge or edges of the printing plate outwardly toward the cylindrical slot opening, upon actuation.
