ABSTRACT:
An apparatus for heating, bending and quenching glass sheets (10) is disclosed as including a first platen (14) and a second platen (22). Both platens (14,22) are deformable for bending a heated glass sheet (12) therebetween. A first heater (18) is integral with the first platen (14) and provides heat in close proximity to the heated glass sheet (12) during the bending to maintain an optimal glass bending temperature.
