ABSTRACT:
The invention is directed to a clamping device for gravure printing cylinders to be processed in an electroplating plant. The clamping device for gravure printing cylinders to be processed in an electroplating plant is equipped, in accordance with a first basic solution, with an interchange holder (1) for a plurality of cone sleeves (2) which have an inside diameter adapted to different spindle ends of various gravure printing cylinders, so that adaptation to a respective identical receiving cone quill (8) is made possible and in the same electroplating plant a plurality of different printing cylinders can be continuously successively processed without the complicated fitting and removal of different collet chucks. According to a second basic solution the interchange holder and the different cone sleeves are not required for the clamping device. Instead, a hardened cone sleeve (21) is used as essential clamping element and clamping is effected with very high contact pressure. Because of the practically gastight connection between the cylinder spindle end and the wall of the hollow cone, very high currents can surprisingly be transmitted.
