Abstract: The system comprises a wiping tank (1), a wiping roller (2) rotatably supported in the wiping tank and having a circumferential surface and cleaning means for cleaning the surface of the wiping roller, said cleaning means comprising at least a first spray unit (4) for spraying clean wiping solution against the surface of the wiping roller and a drying blade (12) placed downstream of said first spray unit with respect to a direction of rotation of said wiping roller for removing wiping solution residues from the surface of the wiping roller. The cleaning means further comprise a cleaning assembly including at least one supporting plate (5; 25) with a series of holes (5?, 30, 31, 32, 33) and holding means (7, 8, 10, 11) for holding the supporting plate, said supporting plate being conformed to extend parallel to a part of the circumferential surface of the wiping roller without touching said wiping roller.

Abstract: The invention concerns an ink fountain with a blade support wherein said blade support comprises several adjacent sections moveable by setting means to vary the distance between said sections and the circumference of an ink fountain cylinder. The ink fountain further comprises a blade interposed between said sections and the circumference of the ink fountain cylinder and having a ridge for maintaining a specific thickness of ink on the ink fountain cylinder, the blade resting directly on said sections and being fixed relative to said blade support.
