A system for cleaning particles from a moving web by engagement with contact cleaning rollers, wherein the web may be moved selectively out of contact with the cleaning rollers to prevent damage to the web surface, such as adherance, stripping, or ferrotyping, resulting from stationary contact with the cleaning rollers. The system includes contact cleaning roller assembly disposed adjacent to and transverse of the web path. Preferably, such assembly includes a rotatable turret supporting a plurality of rotatable contact cleaning rollers, preferably three rollers positioned equilaterally. The turret is positioned relative to the basic web path such that, in a non-operative mode, the web is not in contact with the cleaning rollers, the web path bypassing the cleaning rollers. Thus, during periods of maintenance or other downtime, the web first surface is protected from being damaged by stationary contact with the cleaning rollers. The system further comprises at least one, preferably two, movable backing roller adjacent the second surface of the web, the web passing between the backing rollers and the cleaning rollers. To engage the web with the cleaning assembly into an operative mode, the backing rollers are moved towards the turret to alter the basic web path such that the web first surface is brought into engagement with the cleaning rollers in a second web path.
