A surface winder having an undercut drive roller. An apparatus for winding web material onto a core includes a driven pressure roller having a first end portion, a second end portion, and a central portion intermediate the first and second end portions. When the pressure roller is driven against the core, a first and second nip is formed between the first and second end portions, respectively, and the core. The central portion is undercut so as to space the central portion from the web material being wound onto the core.

Surface winder undercut drive roller apparatus and method

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.
