A dryer device for a sheet-fed rotary printing machine including an impression cylinder and an associated forme cylinder, the dryer device including a radiant drying system and a hot-air drying system acting on sheets in the machine; a frame for releasably receiving the radiant drying system and the hot-air drying system, and a guide mechanism for moving the frame and attached drying systems relative to the impression cylinder.

Drying device for a sheet-fed rotary printing machine

A releasable connection assembly couples fluid supply lines in a printing machine with the use of first and second coupling parts. The first coupling part is part of a subassembly fastened to the printing machine frame and adapted for pivotal movement about the frame. The second coupling part is arranged on a movable assembly, such as a washing unit.

An apparatus for cleaning the cylinders of the printing units of a printing machine is disclosed. The cleaning apparatus is provided with three subassemblies. Specifically, it includes a cleaning subassembly having at least one washing roller for washing the cylinder to be cleaned. The cleaning apparatus also includes a conveying subassembly for transporting the cleaning subassembly into and out of the printing unit. The conveying subassembly is dimensioned to slide into the service orifice in the frame of the printing unit while supporting the cleaning subassembly. The cleaning apparatus is also provided with an actuating subassembly mounted on the frame of the printing unit for removably receiving the cleaning subassembly and for selectively moving the cleaning subassembly between a first position wherein the cleaning subassembly is disposed on the conveying subassembly within the service orifice, a second position wherein the cleaning subassembly is separated from the conveying subassembly and displaced laterally from the service orifice, and a third position wherein the at least one washing roller of the cleaning subassembly engages the cylinder to be cleaned.
