Clamping and tensioning device for an inwardly bent trailing edge of a flexible printing plate disposed in an axial gap at the circumference of a plate cylinder adjustable in axial spacing and cooperating with a blanket cylinder, the printing plate being fixable at a leading edge thereof on the plate cylinder and being tensionable in circumferential direction on the plate cylinder, includes two clamping bars displaceably supported in the axial gap and forming therebetween a clamping slot for receiving therein an inwardly bent trailing edge of the printing plate, the two clamping bars extending axially in the gap within the cross-sectional contour of the plate cylinder and being loadable by reversible opposing clamping forces as well as by reversible tensioning forces in common in tensioning direction of the printing plate, and being respectively braced against the plate cylinder, the two clamping bars being formed with radially outer edges, the clamping and tensioning device being radially displaceably disposed in the axial gap of the plate cylinder, and a device for applying drive forces to the clamping and tensioning device for displacing the clamping and tensioning device with the radially outer edges of the two clamping bars radially outwardly at least to the cross-sectional circumferential contour of the plate cylinder, with the clamped bend of the trailing edge of the printing plate being displaceable back within the contour of the plate cylinder.
