BENDING DEVICE FOR GLASS SHEET

PROBLEM TO BE SOLVED: To make it possible to bend a glass sheet in a direction orthogonal with a transporting direction along the transporting surface formed by a plurality of rollers for bending the glass sheet by inclining these rollers with respect to a horizontal plane and arranging the rollers in such a manner that the inclination directions of the respective neighbor rollers vary alternately. SOLUTION: The rollers of a roller conveyor are arranged to incline alternately in such a manner that the angles of inclination of the rollers increase gradually from an intermediate section of a transporting route to an outlet section. The glass sheet 18 is transported on the transporting surface of the roller conveyor formed to curve in the direction orthogonal with the transporting direction, by which the glass sheet 18 is bent in the direction orthogonal with the transporting direction. Also, the rollers 20A and 20B move successively from above to below from the upstream side in the transporting as the glass sheet 18 is transported, by which the transporting surface of the roller conveyor is curved along the transporting direction and the glass sheet 18 on the transporting surface is bent in the direction along the transporting direction. The glass sheet 18 is bent to multiple shapes by the combination of both described above.
