Abstract

In an apparatus for clamping printing plates for printing presses comprising two clamping strips which are displaceably arranged in a cylinder recess and held by two leaf springs and hook under an end region of the printing plate to be clamped and whose outer contours, in the clamped state, have a curvature corresponding to the cylinder curvature and each of which is bounded by a thrust surface which engages a bent-over edge claw of the printing plate to be clamped, a resilient hose being inserted between the thrust surfaces of the clamping strips and the clamping strips themselves, the clamping strips are adjustable on the one hand in the clamping direction of the printing plates by means of two cams arranged in depressions and on the other hand in a direction opposite to the clamping direction of the printing plates by means of a cam arranged between the leaf springs and in the vertical plane of symmetry of the cylinder.
