Abstract
A glass sheet bending system (10) disclosed includes a horizontal roller conveyor (16) having a roll operator for operating a plurality of conveyor rolls (18) adjacent an associated bending apparatus (22) to control conveyance thereon independent of conveyance on the other rolls of the conveyor. In one embodiment, the roll operator comprises a roll shifter (24) for shifting the rolls (18) along the direction of conveyance during continued rotational driving. In another embodiment, the roll operator comprises a positioning drive (140), that drives the conveyor rolls (18) adjacent the bending apparatus (22) independently of the other rolls of the conveyor. Both embodiments reduce the rate of glass sheet conveyance as the holder receives each glass sheet to reduce sliding at a surface (62) of the holder. Also, repositioning of leading and trailing glass sheets can be initially performed along the direction of conveyance to provide accurate location of the sheets on the holder with respect to each other in preparation for bending on associated molds (68).
