  • Apparatus for cleaning a surface of a moving web
    Patent number: 5930857
    Abstract: Apparatus for cleaning a surface of a moving web of material, particularly photosensitive web material. A particle transfer roller is disposed adjacent the moving web, and driven to a pre-determined speed approaching but not greater than a sensed speed of the moving web. A passive one-way clutch coupled to the particle transfer roller is engaged, such that when the driven particle transfer roller contacts the moving web, the moving web drives the particle transfer roller. A cleaning station is disposed adjacent the particle transfer roller so as to provide renewal of the particle transfer roller.
