<p>A roller assembly for use in a glass bending machine. A bending roller (20) is rotatably mounted on a base bracket (12). The bending roller (20) has a three-piece construction comprising: a central hub (38) having an annular outer surface (38a), opposed side surfaces, and a central axis (28) of rotation; a collar (42) fixed to each side surface of the central hub, said collars (42) having an annular outer surface (42a), inner and outer side surfaces (42b, 42c), and a central axis of rotation (42d). The collars (42) comprise a material and shape which resists scratching glass. The scratch resistant materials may comprise carbon or boron nitride. <IMAGE> <IMAGE></p> |
