ABSTRACT:
A device for actuating a tensioning device for fastening flexible packings to printing-unit cylinders of rotary printing machines, the actuating device having a tensioning shaft for accommodating respective ends of flexible packings, for clamping at least one end of the flexible packings, and an actuating mechanism arranged outside the printing-unit cylinder for activating the tensioning shaft, includes an actuating element passing through a cylinder journal of the printing-unit cylinder and being displaceable axially relative to the cylinder journal, and a transmission element via which the displacement of the actuating element is convertible into a rotational movement of an attachment to the tensioning shaft; and a printing unit and a printing-unit cylinder having the actuating device, as well as a method of operating a tensioning device for fastening flexible packings.
