ABSTRACT:
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.
