ABSTRACT:
The apparatus includes a path-defining roller (28) and a sealing roller (38, 39) in contact therewith to seal the path-defining roller from the housing of the apparatus. A sealing ring (82) surrounds one end of the sealing roller and is urged into contact with a sealing surface (68). The sealing ring, in its relaxed condition, is undersized with respect to the sealing roller and when mounted on the sealing roller exhibits a flat face (96) to the sealing surface. The performance of the sealing is predicable and reliable.
