SETTER FOR MANUFACTURING ARC-SHAPED CURVED GLASS PLATE AND METHOD FOR MANUFACTURING ARC-SHAPED CURVED GLASS PLATE

摘要

Provided are a setter for manufacturing and obtaining an arc-shaped curved glass plate with a large center angle and a method for manufacturing and obtaining an arc-shaped curved glass plate with a large center angle. A setter (1) for manufacturing an arc-shaped curved glass plate is a setter used when manufacturing an arc-shaped curved glass plate (21) by softening and deforming a flat glass plate (20). The setter (1) for manufacturing an arc-shaped curved glass plate has a disposition surface (11). The disposition surface (11) includes a center part (11a) the cross-sectional surface of which has an arc shape and an extended part (11b) that extends from one side end part of the center part (11a). At the cross-sectional surface, the extended part (11b) is positioned between a virtual circle (C), which the center part (11a) follows and a tangent line (L1) on one side end part of the center part (11a).
