Abstract:
Press cylinder structure for securing a printing plate over the cylinder's saddle. This saddle includes a first longitudinal edge permissably provided with a printing plate retainer bar, and the opposite edge of the saddle being spaced from an independent, movable, tensioned, printing-plate locking bar. Such locking bar is spring-loaded relative to the saddle, and is provided with registry orientation means. The locking bar is movable inwardly toward the saddle so as to facilitate printing plate, edge mounting onto the locking bar. Thereafter, the locking bar is urgeable outwardly with respect to the saddle so that tension may be applied to the plate. In the inward progress of the locking bar relative to the saddle, means are provided for releasably fixing the disposition of the locking bar relative to the press cylinder so that a printing plate disposed on the saddle and engagement thereof by the locking bar can be released.
