ABSTRACT:
The invention comprises press bending apparatus including a continuous uninterrupted peripheral shaping rail mounted for vertical reciprocating movement for lifting a heated glass sheet from a roll conveyor and pressing it against a complementary shaping surface. Conveyor rolls are provided exteriorly of the shaping rail for advancing a sheet into position over the shaping rail, and additional separate rolls are mounted so as to be disposed within the confines of the shaping rail for supporting the sheet interiorly of the shaping rail. An arrangement is provided beneath the shaping rail for supporting and driving the interior rolls so as to permit vertical movement of the shaping rail between the interior and exterior rolls.
