Abstract
A device for securing flexible printing plates under tension on a plate cylinder of a rotary printing machine having tensioning rails operatively associated with both ends of the plate and being braceable against side walls of a transverse channel formed in the plate cylinder for tensioning the printing plate includes a device for selectively stretching and compressing at least one of the ends of a printing plate in axial direction of the plate cylinder, the tensioning rail operatively associated with the one plate end being of one-piece construction and having a clamping member disposed at a middle region thereof and respective tensioning segments disposed at end regions thereof and actuable for stretching and compressing the one plate end.
