Abstract
A composite blasthead (18,20,70,72,118,120) for a quench station (16) of a glass sheet tempering system (10) is disclosed as including outer layers (28,71,73,128,128') and an inner layer comprising inserts (30,32,34,74,76,130,130') therebetween for defining passages (36,80,82,136) through which cooling gas is supplied to a glass sheet in order to provide tempering. All of the inserts have inner end portions (38,40,42,81,138,138') that cooperate to define inlets (44,86,144,144') to the passages and also have outer end portions (46,48,50,88,146,146') that cooperate to define passage outlets (52,90,152,152') through which the quenching gas exits. All of the passages have a circular cross section along substantially the entire length of the passages. All of the inserts are of a configuration such that the passages of each blasthead are aligned with the passages of the other blasthead, so that the gas impinges on the glass surfaces in an opposed relationship with a uniform pattern over said surfaces thereby optimizing the degree of glass tempering.
