Title:
PLATE GLASS PRODUCTION METHOD, PRODUCTION DEVICE THEREFOR, AND PLATE GLASS
Document Type and Number:
WIPO Patent Application WO/2022/097324
Kind Code:
A1
Abstract:
This plate glass G production method relates to a plate glass G having a first region G1 and a second region G2 laid next to one another in the width direction and a scribe line S formed in the boundary portion of the regions G1, G2, on the side of front surfaces Ga, Gx, the method comprising a snapping step in which, in a state where the first region G1 is in contact with and supported by a back surface supporting member 3 from a back surface Gb side while the plate glass G is in a vertical attitude, a force oriented toward a back surface Gy is applied to the second region G2, thereby splitting the plate glass G along the scribe line S and cutting off the second region G2. In the snapping step, the first region G1 and the back surface supporting member 3 are brought into contact with one another so as to form a warping portion Gws following an up-down direction protruding on the front surface Ga, Gx side in the scribe line S formation region Gs.
