Abstract
A quench station (14) including apparatus for quenching a heated glass sheet G conveyed by rolls (22) of a roller conveyor (20) is disclosed as including upper and lower sets of vertically aligned blastheads (32) having outlets (34) that are positioned closer to the conveyed glass sheet than the conveyor roll radius R and which are oriented and sized to provide highly efficient symmetrical quenching by aligned locations (36) of impingement with the oppositely facing surfaces of the glass sheet for heat strengthening or tempering. The blasthead outlets (34) are preferably round. A set of upper roll mimics (38) located above the conveyor rolls (22) in a vertically aligned relationship cooperate with the blastheads (32) in providing symmetry that results in uniform quenching of both glass sheet surfaces.
