An apparatus (3) and a method for automatically cleaning rollers, and in particular impression cylinders (1) provided with blankets (2), or counter-pressure cylinders. The apparatus (3) includes a reeling-off roller (6) and a reeling-on roller (7). The roller (6) carries a cleaning web (9) which extends from the roller (6) over a pressure pad (11) attached to a holder (14) and from there to the reeling-on roller (7), optionally via one or more guide rolls (10). Positioned between the reeling-off roller (6) and the pressure pad (11) is a spray device (12) which delivers cleaning agent (13) to the web. The holder (14) is attached to a compressed-air piston (15) which is able to move the holder (14) backwards and forwards, towards and away from the impression cylinder (1). During this reciprocating movement, the cleaning web (9) is moved progressively from the reeling-on roller (6), over the pressure pad (11) and to the reeling-on roller (7). |
