  • Patent number: 7966933
    Abstract: An apparatus and method for clamping printing plates on a plate cylinder is disclosed. A clamping element is integrated into a lockup slot of a plate cylinder with an actuating element. The clamping element is transferred by the actuating element between a first position, where the clamping element clamps the leading end and/or the trailing end of the printing plate, and a second position, where the clamping element releases the leading end and/or the trailing end of the printing plate. The clamping element can be adjusted exclusively in the radial direction of the plate cylinder and the actuating element exclusively in the axial direction of the plate cylinder such that, depending upon the relative axial position of the actuating element with respect to the clamping element, the clamping element is displaced either radially outwardly for clamping the printing plate or is displaced radially inwardly for releasing the printing plate.
