The glass tempering system includes an elongated furnace in which a horizontal conveyor oscillates a glass sheet between opposite ends of the chamber in a manner to shorten the necessary furnace length to heat the glass to its quench temperature. A load station at one end includes a horizontal conveyor driven by the same drive mechanism as the furnace conveyor during the index cycle so that a glass sheet is received while another glass sheet is being indexed to the quench unit. A second motor drives the quench unit conveyor in an oscillating manner. The two drive mechanisms are coupled during the index cycle so that a tempered glass sheet is conveyed from the quench unit to an unload station as a heated glass sheet is being conveyed to the quench unit. The conveyor of the unload station is driven by the quench unit drive during the index cycle to receive the tempered glass sheet. Each of the conveyors includes drive chains which frictionally drive their conveyor rollers. The conveyor rollers of the load and unload stations are lifted off their respective drive chains to stop the rollers for unloading of the glass thereon. |
