Glass quenching apparatus

摘要

A glass quenching apparatus (10) for quenching a glass sheet (12) heated to a predetermined temperature, includes a first nozzle group (27, 37) for jetting blower air onto opposite surfaces of the glass sheet, and a second nozzle group (79) for jetting compressor air onto at least one of the opposite surfaces of the glass sheet. The first nozzle group is comprised of stationary nozzles (27a, 37a), and the second nozzle group is comprised of movable nozzles (78) which are capable of moving parallel to a plane of the glass sheet. The glass quenching apparatus of the foregoing construction is able to quench the glass sheet uniformly over the entire area thereof without undue wastage of quenching air.
