ABSTRACT:
A method of and apparatus for bending glass sheets to relatively sharp angles. The apparatus includes a sectionalized primary press bending member having articulated end sections for sharply bending portions of a glass sheet about lines superheated by a radiant energy heat source located above the primary press member. A reciprocal brake bar is extended into engagement with the glass sheet along the heated focal line to assist the articulated press end sections in bending the glass. Clamping devices can be used in lieu of the brake bar to secure the heat-softened glass sheet to the press member shaping surface during bending. A supplemental press member, mounted above the primary press member, is provided with shaping elements having shaping surfaces complemental to the shaping surfaces of the primary press articulated end sections for pressing the glass end portions therebetween into conformity with these shaping surfaces.
