ABSTRACT:
A printing machine has a printing station, certain components of which require intermittent cleaning due to fouling by the printing ink. An endless printing blanket is trained about a reversing roller that is spaced lengthwise of the machine from the printing station; the printing blanket has an upper run extending beneath the printing station and carrying the workpiece to be printed. The upper run is inclined downwardly with respect to the horizontal in direction from the printing station towards the reversing roller. A cleaning arrangement is provided for at times admitting a cleaning liquid into the printing station so as the clean the ink off the components, whereupon the liquid will run off the components onto the upper run of the printing blanket. Liquid-intercepting side members are provided which extend along the respective lateral edge portions of the upper run to the reversing roller and which prevent the liquid from running off the lateral edge portions into the machine.
