ROLLER MEANS FOR GLASSWORKING, TEMPERING, OR ANNEALING:
(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.
