ABSTRACT:
A quench roll (20) for a glass sheet tempering system of the roller conveyor type includes a helical support (44) with a construction that does not mark conveyed glass sheets but which is nevertheless capable of withstanding breaking of glass sheets without being cut so as to require repair. The helical support (44) is wrapped about a shaft (42) of the roll (20) and includes a core (46) as well as a nonmetallic outer covering (50). The outer covering (50) is preferably a synthetic organic polymer such as silicone rubber or Teflon and, for best results, the covering has an outer sleeve (50a) of ceramic fibers. The core (46) is preferably metallic and made of wire strands (52) that facilitate wrapping thereof in the helical configuration. Spring end connections (54) disclosed prevent unwinding of the helical support (44) during glass sheet conveyance. The helical support (44) has particular utility with frictionally driven quench rolls and preferably has an outer diameter equal to the diameter of friction drive surfaces (78 ) of the roll.
