<p>The invention relates to a method and apparatus for developing an edge stress in a windshield in a windshield bending furnace. Adjacent to a ring mould (2) is located a metallic, flat extra frame (3) in a manner that the lower surface of a bent windshield (1) remains at a small distance from extra frame (3). The compression stress of glass edge can be adjusted by varying the distance of extra frame (3) from glass and/or by varying its glass-oriented dimension.</p> |
