ABSTRACT:
A glass bending and tempering apparatus (20) is disclosed as including a pair of opposed bending platens (24) for receiving a heated glass sheet (22) to be bent therebetween. At least one of the bending platens (24) is deformable and includes an actuator (32) for deforming the platens from a planar shape to a bent shape to bend the heated glass sheet. Said one platen (24) includes quench openings (42) that move with said platen during the deformation of the platen and subsequently supply quenching gas to temper the bent glass sheet (22).
