Abstract
An apparatus (10) for conveying abrasive web (16) of indeterminate length, such as photographic media, has first and second closely spaced rollers (12, 14) with at least one of the rollers (12, 14) having a polymeric/inorganic composite media bearing surface (70). The abrasive web or media (16) is disposed between a nip (18) defined by the close spacing between the rollers (12, 14) and is in moving contact with the polymeric/inorganic composite media bearing surface (70) while being conveyed through the nip (18).
Claims5
Apparatus for conveying abrasive media of indeterminate length, comprising:
- a frame;
- first and second rollers mounted for synchronous rotation in said frame, said first and second rollers being closely spaced to form a nip therebetween, and wherein at least one of said first and second rollers has at least a media bearing surface for contacting said abrasive media passing through said nip, said media bearing surface comprising, in a mixture, a polymeric matrix and an inorganic particulate material, wherein said inorganic particulate material is in said mixture at a concentration in a range of between about 5% by weight and 50% by weight;
- and,
- drive means operably connected to any one of said first and second rollers for rotating said any one of said first and second rollers.
