Abstract: A glass sheet quench station (16) includes first and second quench sections (24 and 26) that cooperate with a three position shuttle (28) and a control (30) to transfer glass sheets through the quench station with partial quenching performed at the first quench station and completion of the quenching at the second quench section. This glass sheet quenching method with two stage quenching shortens the cycle time to provide increased production.

Abstract: Apparatus (22) and a method for positioning a heated glass sheet on rolls (26) on a conveyor (24) utilizes an air hearth (28) for supplying upwardly directed pressurized air and an elevator (32) for providing relative movement between the rolls and the air hearth for either the conveyance or floating of the glass sheet over the rolls to allow a positioner (36) to position the heated glass sheet while out of engagement with the rolls. The air hearth (28) has stationary supports (38) and the elevator (32) has cam actuators (42) that move the rolls (26) of the roll conveyor (24) vertically with respect to the stationary air hearth between raised and lowered positions to provide either the roll conveyance or floated glass sheet positioning.
