<p>A method and apparatus is achieved for creating or restoring a high friction surface to a drive roller (52). Abrasive pads (12) define a scrubbing surface for acting upon a media roller's surface (54-58). As the roller's surface is scrubbed, creping occurs which increases the surface's coefficient of friction between the roller and media sheet ('COF(rm)'). In one embodiment, the creping apparatus is formed by a pair of plates (16, 18) hinged along one edge (30) and open along an opposite edge (28). A spring (19) is positioned between the plates biasing the plates apart at the open end. One or more abrasive pads are attached to the outer surface of one plate (18). To create or restore a high friction surface, the apparatus (10) is positioned adjacent to the roller (52). By approximately defining the force applied between the roller (52) and abrasive pads (12) and by using an abrasive pad of known grit, initially surface contaminants, if any, are scrubbed from the roller surface (54-58).</p> |
