Abstract

A sheet glass bending apparatus includes a pressing stage disposed downstream of a heating furnace and a quenching stage disposed downstream of the pressing stage. The sheet glass bending apparatus also comprises a lifting/lowering member for vertically moving a ring mold which supports a lower surface of a glass sheet in the pressing stage, and a shuttle reciprocally movable between the pressing stage and the quenching stage while holding the ring mold, the shuttle being operable to receive the ring mold from and transfer the ring mold to the lifting/lowering member.
