ABSTRACT:
A method and quench unit (10,10a,10b) disclosed provide tempering of a heated glass sheet by impinging pressurized air against its opposite surfaces while within a chamber (18) at super-atmospheric pressure. An enclosure (16) of the quench unit defines the chamber (18) and is preferably pressurized by the spent quenching air which is delivered through opposed blastheads (12). The spent quenching air is removed from the chamber (18) to maintain the air pressure below a predetermined level. An air supply system (24) disclosed cools and pressurizes the spent quenching air received from the chamber (18) and then feeds this air back to the blastheads (12) in a recirculating fashion for impingement with the glass sheet in the chamber.
