摘要： A device for securing a flexible printing plate under tension on a plate cylinder is used in combination with the plate cylinder which has an axially extending channel with side walls formed therein. There is a tensioning rail operatively associated with each end of the printing plate. Each tensioning rail is braceable against one of the side walls of the axially extending channel formed in the plate cylinder for tensioning the printing plate. The device includes one of the tensioning rails operatively associated with at least one of the ends of the printing plate which is one-piece and has a central clamping member disposed at a middle region thereof for clamping a center of the one plate end. Respective tensioning strips are disposed at end regions of the tensioning rail. Each tensioning strip is mounted for axial movement on the tensioning rail and has an edge clamping member mounted thereon for clamping an edge of the one plate end. A selectively rotatable cam member is mounted on the tensioning rail and acts on the tensioning strip to produce selective axial movement of the tensioning strip in order to selectively stretch or compress the one plate end.
