Therefore, by cutting the curved plate-shaped glass 12 using the breaking wire L, the glass curved plate 11 from which the unnecessary portion GP of the curved plate-shaped glass 12 is removed can be easily obtained.

(2) The support portion 22 of the mounting table 19 in the glass processing apparatus 18 has a convex surface along the inner surface of the curved portion 15 of the curved plate-shaped glass 12.
In this case, since the curved plate-shaped glass 12 can be stably supported by the support portion 22 of the mounting table 19, the breaking wire L can be accurately formed on the curved plate-shaped glass 12. Therefore, it is possible to obtain the glass curved plate 11 having higher dimensional accuracy.

This is a method for manufacturing a curved plate 11. The method for manufacturing the glass curved plate 11 includes a mounting step, a breaking wire forming step, and an unnecessary portion removing step. In the mounting step, the curved plate-shaped glass 12 is mounted on a mounting table 19 having a support portion 22 that supports the inner surface of the curved portion 15. In the breaking line forming step, the blade body 21 is advanced along the direction D in which the curved portions 15 of the curved plate-shaped glass 12 placed on the mounting table 19 are connected, thereby breaking into the outer surface of the curved plate-shaped glass 12.

(11) The curved plate-shaped glass 12 is formed by bending a flat plate-shaped glass (rectangular or square) having four sides using a molding die so that the opposite end edges are brought close to each other. Here, for example, in the case of flat glass made of crystalline glass or flat glass having a thickness of 1 mm or more, it is difficult to be thermally deformed. When forming a curved glass 12 from such a flat glass, if the length between the opposite end edges of the flat glass (rectangle or square) is set longer, both ends of the flat glass can be formed. The curved portion 15 along the molding die can be easily formed by utilizing the weight of the edge side. However, when the length between both ends of the flat glass is set to be longer, the product (glass curved plate) is placed on both ends of the flat glass, that is, on both ends of the molded curved glass 12. There will be an unnecessary part as 11).

The curved plate-shaped glass 12 used in the method for manufacturing the glass curved plate 11 of the present embodiment is obtained by a molding step of bending a flat plate-shaped glass having four sides so that the opposite end edges are brought close to each other by using a molding die.

In this case, by using flat glass having unnecessary portion GP that is unnecessary for the glass curved plate 11 on both end edges as described above, for example, even a flat glass made of crystalline glass can be easily obtained. The curved portion 15 can be formed in the glass. Further, since the method for manufacturing the glass curved plate 11 of the present embodiment includes the mounting step, the breaking wire forming step, and the unnecessary portion removing step described above, the glass curved plate 11 from which the unnecessary portion GP has been removed can be easily obtained. Obtainable. As described above, the method for manufacturing the glass curved plate 11 of the present embodiment is particularly advantageous when, for example, a glass curved plate 11 made of crystalline glass is obtained.

The curved plate-shaped glass 12 may be carried into the mounting table 19 fixed to the. However, according to the mounting table 19 provided so as to be able to reciprocate between the carrying-in section 29 and the processing section 30 as in the present embodiment, when the curved plate-shaped glass 12 is mounted on the mounting table 19. For example, since it becomes easy to avoid contact between the breaking wire forming mechanism 20 and the curved plate-shaped glass 12, it is possible to suppress the occurrence of breakage of the curved plate-shaped glass 12.

The position where the breaking wire forming mechanism 20 of the glass processing apparatus 18 forms the breaking wire L is not limited to the above embodiment, and for example, the first extending portion 16 or the second extending portion of the curved glass 12 It may be 17.

-The curved plate-shaped glass 12 may be formed of glass other than crystalline glass.
The curved plate-shaped glass 12 is not limited to the one bent by using a molding mold so that the opposite end edges of the flat glass are brought close to each other. For example, the curved portion 15 is continuously formed from the molten glass. It may be the obtained one or a semicircular tubular one obtained by cutting the tube glass along the tube axis direction. Even in this case, by using the glass processing apparatus 18, it is possible to easily remove unnecessary parts as a product.

-The glass processing device 18 can also be applied to the processing of curved plate-shaped glass having a bent portion having an L-shaped cross section or a V-shaped cross section. In this case, for example, the mounting table 19 of the glass processing apparatus 18 may be changed in shape of the support portion 22 as necessary.
