摘要： PROBLEM TO BE SOLVED: To smooth the transportation of a glass sheet and to bend the glass sheet without the occurrence of damage by vertically moving plural rollers for forming a transportation plane according to the transporting position of the glass sheet, thereby bending part of the transportation plane. SOLUTION: When a glass sheet 18 arrives at a roller 20A on the inlet side, the transportation plane formed between all the rollers 20a to 20M is horizontal. When the glass sheet 18 is transported, rollers 20B and 20C descend. As the glass sheet 18 is transported, rollers 20D to 20F move downward and the transportation plane formed between the rollers 20D to 20F is deformed to a gently downwardly crowning curvilinear surface of a large radius of curvature. The glass sheet 18 is deflected downward along the curvilinear surface of the rollers 20D to 20F by its own weight at the time of passing on the rollers 20D to 20F and is deformed to the shape complying with the curvilinear surface. A motion controller controls the respective servo motors of the rollers 20D to 20F in such a manner that the transporting speeds of the horizontal direction components of the glass sheet 18 by the rollers 20D to 20F are equaled to each other.

摘要： 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.

摘要： PROBLEM TO BE SOLVED: To execute bending to a desired curvature by pressing the portions existing between two adjacent transporting rollers of the glass sheet with a pressing roller arranged above between the two adjacent transporting rollers, thereby applying a load to the portion and bending the glass sheet. SOLUTION: Usually, a sandwich roller 64 exists in a direction normal to the transportation plane. In the case of bending of the glass sheet, the roller is inclined at a prescribed angle θ with the direction where the glass sheet is bent from the normal direction. As a result, the prescribed bending load is applied atop the glass sheet between the transporting roller 20M and the transporting roller 20N and the glass is bent at three points between the transporting rollers 20M and 20N and the sandwich roller 64. Consequently, the glass sheet is bent to the prescribed curvature. The sandwich roller 64 may be oscillated at an arbitrary angle. The sandwich roller 64 is merely necessitated to be inclined at the larger angle α of inclination in order to bend the glass sheet at the smaller radius of bending.
