ABSTRACT:
Apparatus and a method for forming glass sheets includes a topside transfer platen (44) that releases a heated glass sheet onto a mold supported in an upper position by a mold support frame assembly (62) which then moves the mold vertically downward and rotationally to a lower position for movement horizontally on a track (66) from below the topside transfer platen for continuation of the forming. The apparatus includes an elevator mechanism (84) having a pair of elevators (86) and an associated pair of actuators (88) that are movable different extents in order to provide the vertical and rotational movement of the mold frame support assembly (62).
