Abstract
A roller assembly for use in a glass bending machine comprises a base bracket, a bending roller rotatably mounted on said base bracket, the bending roller having a three-piece construction comprises a central hub having an annular outer surface, opposed side surfaces, and a central axis of rotation; a collar fixed to each side surface of said central hub, the collars having an annular outer surface, inner and outer side surfaces, and a central axis of rotation; the collars comprising a material and shape which resists scratching glass, the collars being spaced apart with a center section of the hub between them to allow the roller to be driven individually by a friction member whereby the friction member is adapted to run on the center section of the roller to rotate the roller, and a glass sheet is adapted to run on the larger collars and not be scratched by the center section.
