Clamping device for clamping a flexible covering on a cylinder of a printing machine

A clamping device for clamping a flexible packing of a cylinder of a printing press, the cylinder defining an axial channel on a cylinder surface, the clamping device comprising:

• a clamping body with a surface defining, with an opposing surface of the cylinder, a clamping gap in the channel, one end of the packing passing through an opening of the channel;
• a pressing element which exerts an elasticity force on said clamping body, said pressing element including a bearing element moveable in a first direction against the elasticity force at right angles to an axis of rotation (Dz) of the cylinder, said bearing element supports said clamping body in said first direction, so that said clamping body and said opposing surface are pressed against each other with a clamping force;
• said elasticity force presses said clamping body simultaneously against said opposing surface and an additional opposing surface formed on another side of the channel diametrically opposite with respect to the channel;
• said bearing element forming a guideway along which said clamping body can be moved in a second direction that is not parallel to said first direction and is at right angles to said axis of rotation of the cylinder while said clamping gap is maintained, said guideway firmly supporting said clamping body in a plurality of positions along said second direction, said clamping body being movable with respect to said bearing element along said guideway.
