ABSTRACT:
A clamping and pulling device for cylinder packings in a printing press, the device having gripper elements disposed in a cylinder gap extending axially at a circumference of a cylinder, and power elements for actuating the gripper elements to grip and firmly hold an end of a respective packing extending around an edge defining the gap and into the gap and, when actuated by the power elements, for pulling the cylinder packing around the edge defining the gap into the gap, includes abutments on the cylinder, the gripper elements being formed of two clamping bars having respective opposing clamping jaws braced against the abutments, respectively, and, in an angular position defined by the abutments on the cylinder and the arrangement of the clamping jaws at a bent-away portion of the cylinder packing, being disposed with a vertex directed opposite to a tensioning direction, tensioning forces of a respective power element serving to load at least one of the clamping bars in the direction of a mutually extended position of the two clamping bars.
