Abstract
A glass sheet forming apparatus (20) for continuously forming a heated glass sheet includes a roller conveyor (30) defined by a plurality of interposed first and second conveyor rolls (32,34). The first conveyor rolls (32) are mounted in a plane defined by X and Y axes for conveying the glass sheet. The second conveyor rolls (34) include independent first and second roll portions (36,38). At least one of the roll portions (36) is movable in the plane to establish rotation of the roll portion (36) with respect to a Z direction. The second conveyor rolls (34) are mounted in a plane defined by X' axis. A first actuator (44) moves the movable roll portions (36) so that part of the movable rolls (36) are elevated above the X' axis and above the first conveyor rolls (32) whereby the roller conveyor (30) becomes non-planar and a heated glass sheet is formed as a result of the non-planar conveyor shape and upward action of the second conveyor rolls (34).
