ABSTRACT:
A printing machine for webs of paper or the like has a flat horizontal screen which is stationarily but removably mounted in the machine frame above the path of intermittent longitudinal movement of the web. A hollow air-permeable counterpressure cylinder is mounted below the path of the web and is reciprocable relative to the screen with a carriage which further supports a printing medium applying unit at a level above the screen. The cylinder is rotated during the printing stroke while a first squeegee of the applying unit forces printing medium through the screen and into contact with the web. During the next-following return stroke, the cylinder is held against rotation and a second squeegee of the applying unit spreads out the printing medium on the screen. At the same time, the web is advanced forwardly through a preselected distance. The carriage can move the applying unit to a position laterally of and out of register with the screen; at such time, the squeegees are located above an open-top pan which is mounted in the frame, and the entire screen is then accessible from above.
