A web cleaning apparatus and method for cleaning the surface of a web (22), for example a photographic film. The apparatus has a rotatable particle transfer roller (10) for removing particulate contamination from the web and a rotatable renewal roller (30) having a cleaning surface (36) for contacting and cleaning the particle transfer roller. Wiping contact is established between the particle transfer roller and the renewal roller to effectuate cleaning of the transfer roller. An absorbent cleaning member (46) is positioned in a cleaning fluid reservoir (32) for wetting and cleaning the cleaning surface of the renewal roller.

Apparatus and method for cleaning the surface of a web

Disclosed herein is a housing for a disk of filter material. The housing includes two disk-shaped parts. One of the housing parts includes a radially-inwardly facing cylindrical surface for locating a filter disk. The other housing part includes a radially-outwardly facing cylindrical surface. The two cylindrical surfaces telescope together during assembly and serve to locate the housing parts relative to one another in directions parallel to the general plane of a filter disk in the housing. The radially inwardly facing cylindrical surface serves to locate a filter disk during assemble. Radially inwardly of the cylindrical surfaces is resilient means for engaging and squeezing the annular peripheral margin of the filter disk for at least partially preventing material being filtered passing radially outwardly of the filter disk and for totally preventing material bypassing the filter disk. Radially outwardly of the cylindrical surfaces is second resilient means providing a seal between the two housing parts for preventing any leakage out of the filter disk, passing to the exterior of the housing.
