Abstract:
A cylinder for a rotary printing machine mounted with journals in opposing side walls of the printing machine comprising:a cylindrical body having a longitudinal axis and first and second ends;first and second journals projecting from the first and second ends of the cylindrical body;a drive acting on the first journal;a structural unit preventing exposure of the cylinder on a side of the second journal and being connected to the cylinder;a screw element capable of being screwed into the cylinder and for connecting the structural unit to the cylinder at a separation point at which the cylindrical body abuts the second journal; anda jamming device connected to the screw element and being adapted for moving between a coupled position and an uncoupled position, wherein the screw element is prevented from rotating with the cylindrical body when the jamming device is in the coupled position, thereby causing movement of the screw element along the longitudinal axis during rotation of the cylindrical body via the drive.
