Abstract
A process for quenching heated glass sheets is performed by locating a glass sheet between a pair of spaced quench units (28) and directing from first and second arrays of nozzles (34, 64) cryogenic flows (36) interspersed with pressurized air flows (66) so as to cooperate with each other in providing the quenching. In one practice the interspersed cryogenic flows (36) and the pressurized air flows (66) are provided at the same time as each other. In another practice, the interspersed cryogenic flows (36) and pressurized air flows (66) are provided at different times.
