できる。Therefore, the net / wire remaining after connecting the main body portion and the cutout portion after splitting should be broken without contacting the cut end face of the cutout portion with the side of the cut end surface of the main body portion. As a result, it is possible to form a good quality cut end face without damaging the cut end face side, improve the product yield, and also improve the strength of the material used as a net or wire. The cullet powder is prevented from being generated by eliminating the damage on the cut end face side, and it is possible to have a wider selection range.Trouble such as damage to the glass surface that is likely to occur secondarily by the cullet powder. Can be wiped out.

ら折り割ることができる。As described above, according to the present invention, the plate glass with the net / wire material continuously fed horizontally is provided with a cutting groove for partitioning the main body side and the cutout side. After that, by pushing down the cutout side and applying stress so that vertical cracks grow from the side of the cutting groove, the cutout part can be broken from the main body side while leaving the nets / wires connecting to each other. .

のもとで確実に破断することができる。Under this condition, after the cutout portion is folded from the body portion side, the cutout portion side is held by a chuck, and a fulcrum near the body portion is pulled up, and at the same time, in the horizontal direction. By rapidly projecting, the residual mesh / wire material interposed between the main body portion and the cutout portion can be reliably broken under a strong tensile force.

できる。For this reason, the net / wire remaining after connecting the main body portion and the cutout portion after the splitting should be broken without making the cut end face of the cutout portion abut against the cut end surface of the main body portion. As a result, it is possible to form a good quality cut end face without damaging the cut end face side, improve the product yield, and also improve the strength of the material used as a net or wire. The cullet powder is prevented from being generated by eliminating the damage on the cut end face side, and it is possible to have a wider selection range.Trouble such as damage to the glass surface that is likely to occur secondarily by the cullet powder. Can be wiped out.
