| Zusammenfassung: | 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. |
