ABSTRACT:
A device for clamping flexible printing plates on the plate cylinder of rotary printing presses can have tensioning bars provided in a recess of the plate cylinder, to which tensioning bars the ends of the printing plates can be fastened, and can also be provided with an apparatus for correcting the diagonal register of the plate cylinder by providing swivelling of the tensioning bars. The adjustment apparatus can be configured with relatively few joints and the adjustment can be done with as little play as possible and with only minimal influencing of the set values for the circumferential and lateral registers. The arrangement provides a configuration wherein at least one of the tensioning bars can be axially displaced during the swivelling of the tensioning bars in a circumferential direction within the plate cylinder.
