Abstract
A clamping device for a printing cylinder with two holders arranged on a joint axis, the holders each having a recess for receiving one end of the printing cylinder and being arranged with their recesses oriented towards each other and positioned adjustably to each other, with at least one of the recesses having a contact surface on which the allocated end of the printing cylinder is held during clamping. At least one of the holders comprises a carrier and a contact element fastened on the carrier on which the contact surface is formed. The contact element comprises a material which has a higher current conductivity and/or thermal conductivity than steel. In particular, copper or a copper alloy is suitable as a material for the contact element.
