ABSTRACT:
A printing cylinder having an axis-parallel channel in the cylinder, the channel narrowing toward the surface to form a slot for receiving the ends of a covering; a clamping member arranged in the channel and urged toward the slot by springs, the clamping member having at least one recess facing a respective at least one wall of the channel; and at least one supporting element arranged inside the channel and engaging a respective recess of the clamping member. A pair of adjusting elements arranged at the ends of the cylinder support the clamping member so that the clamping member can be radially displaced, the adjusting elements being arranged so that movement of the adjusting elements causes relative movement between the supporting element and the clamping member, whereby the clamping member is caused to move radially for clamping and unclamping the ends of the covering in the slot.
