(under the class definition) Apparatus having a generally cylindrical work contacting surface, which surface revolves about the longitudinal axis of the cylinder with rolling motion relative to the surface (a) of molten or hot semisolid glass during glassworking or (b) of solid or semisolid glass during heat treatment to effect tempering or annealing thereof or during other treatment to effect physical or chemical changes thereof.
(1) Note. A patent to a roller, per se, disclosed solely for use in a glassworking apparatus is not classified in Class 65 if the roller is solely for conveying or feeding to a work treating station or between work treating stations provided that the roller is not synchronized with or controlled by means associated with the operation of a work treating station.
