Abstract: 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.

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.
