Abstract
The invention relates to a method and apparatus for developing an edge stress in a windshield bending furnace. Adjacent to a ring mould is located a metallic, flat extra frame in a manner that the lower surface of a bent windshield remains at a small distance from extra frame. The compression stress of glass edge can be adjusted by varying the distance of extra frame from glass and/or by varying its glass-oriented dimension.
