Abstract
The present invention relates to a method and an apparatus for bending a glass sheet, and has an object of achieving high forming accuracy of a glass sheet along a perpendicular direction perpendicular to a conveying direction of the glass sheet, in particular, to obtain high forming accuracy both along the conveying direction and the perpendicular direction. An apparatusfor bending a glass sheet for bending a heated glass sheet G while the glass sheet G is conveyed in a conveying direction X by a roller conveyercomprising a plurality of conveying rollers; the apparatuscomprising a plurality of straight rollers that are arranged upper and lower positions across a conveying surface for the glass sheet G and not curved on the conveying surface, and a plurality of curving rollersarranged upper and lower positions across the conveying surface for the glass sheet G on adjacently downstream side of the straight rollersand curvable along a perpendicular direction Y in the conveying surface so as to bend the glass sheet G along the perpendicular direction Y.
