Document Type and Number:
WIPO Patent Application WO/2022/270288
Kind Code:
A1
Abstract:
A method for producing a plate glass, the method comprising a snapping step for snapping a plate glass G in a vertical posture along a scribe line S, wherein: the plate glass G has a first region G1 and a second region G2, which are arranged to be adjacent to each other in the width direction; the scribe line S is formed in the boundary part of the first region G1 and the second region G2 on the front surface G1a, G2a side of the plate glass G; and in the snapping step, a force directed toward the back surface G2b side is acted on the second region G2 in a state where the first region G1 is in contact with and supported by a back surface supporting member 3 from the back surface G1b side of the plate glass and the second region G2 is sucked and held by a suction mechanism 6 from the back surface G2b side, thereby cutting out the second region G2, while having a crack extend starting from an end of the scribe line S. Consequently, the present invention is able to improve the quality of snapping.
