Abstract: The ink return circuit of a flexographic printing machine, for receiving ink from the ends of the gutter formed by a stereo transfer roller and a pressure regulating roller, comprises, at each end of the rollers, a vertical deflecting spout for receiving ink from the gutter, each spout having three doctor blades comprising a first blade extending substantially along the line of centers of the rollers and inclined to form an overflow and two lateral blades extending perpendicular to the first blade and to the end faces of the rollers. The spouts are biased against the end faces of the rollers and form part of a set of interchangeable spouts.

Abstract: The inking and washing circuit of a flexographic printing machine includes a device comprising a fixed plate on which an immersion pump assembly is mounted with the pump below the plate, and lifting means for receiving a container of ink or for washing purposes and for lifting the container up to a position against the underside of the plate in which the pump is within the container. Washing nozzle means are mounted on the underside of the plate along a closed shape surrounding the pump assembly, which shape is within the open mouth of the washing container but outside the open mouth of the ink container.
