Abstract: Cloth feed control unit of a cleaning device for printing machine cylinders. Provided is a position sensor (30), which generates signals linearly in proportion to the radial variations in the distance of the peripheral surface of a cleaning roller (8, 10) from the position sensor (30). The signals can be used to calculate the length of a cleaning cloth that is on a cloth roller and/or to control the cloth feed. The cloth feed control is carried out preferably in combination with signals of an encoder (44), which detects the rotation-increments of a cloth roller.

Abstract: A fluid system (4) of a printing machine cleaning device (6) has at least one distributor valve (2) with an inlet (8), at least two outlets (10), a locking element (12) and a locking element seat (14). The at least two outlets (10) are each simultaneously separated, in terms of flow, from the inlet (8) or simultaneously connected, in terms of flow, to the inlet (8).
