ABSTRACT:
A quick-action plate clamping mechanism for a plate cylinder of a printing press consists of a pressure strip disposed axially in a recess along the gap in the plate cylinder wherein the recess extends behind the plane of the rear gap wall and parallel thereto, the pressure strip being displaceable in the gap by means of an eccentric bolt which is disposed outside the cylinder center plane parallel to the clamp screws in the rear clamping bar and with specially formed recesses in the pressure strip and corresponding projections on a co-acting member being provided which are respectively situated opposite the clamp screws and supported by compression springs thereby enabling a uniform parallel clamping movement to be carried out in the direction of the rear clamping bar.
