Abstract
Apparatus and methods for bending thin glass sheets are described. The methods and apparatus described include positioning an auxiliary heater between a furnace and an entrance to glass bending station and/or positioning a downstream auxiliary heater between a glass bending station and a quench station. Also described are apparatus and methods for bending thin glass sheets by compensating for heat loss and maintaining the glass viscosity within a workable range for the bending or forming operation. Auxiliary heating elements can be placed in locations that would otherwise provide for excessive heat loss.
