Abstract
Apparatus for clamping printing plates for rotary printing presses, having one or more clamping strips which are arranged so that they are laterally displaceable in a cylinder recess, which grip under an end region of the plate to be clamped and whose outer contour has a curvature corresponding to the cylinder curvature and is bordered by a pressure surface which engages a bent-over edge claw of the plate to be clamped, an insertable, resilient strip being inserted between the pressure surfaces of the clamping strips and a compression strip which is adjustable radially with respect to the cylinder circumference, wherein the clamping strip is adjustable in the clamping direction of the printing plates by means of two or more hydraulic cylinders which are supported at their rear and on the adjacent cylinder wall.
