ABSTRACT:
A glass sheet is heated to a forming temperature in a heating furnace, the heated glass sheet is conveyed along a conveying plane defined by a plurality of rollers of a roller conveyer, and is moved up and down on the rollers according to the position of the glass sheet to curve a part of the conveying plane with respect to the glass sheet conveying direction to bend the glass sheet to have a desired curvature by its own weight. The rollers are curved rollers.
