- the moving speed is lower than the moving speed when moving along the straight part 15.For this reason, in the rounded part, the switching of the pressing force is dense with respect to the moving distance of the cutter wheel 4, and the strong pressing force is A cutting line is made with a large percentage of. For this reason, it is possible to deepen and cleanly put you in the Earl section. As described above, when the glass plate 2 on which the cut line 3 is formed is broken along the cut line 3, the cut surface becomes a clean surface free from cracks.
- the cutter wheel 4 that forms the cut line 3 on the glass plate 2 and the cut line 3a that is to be formed on the glass plate 2 in advance are formed along the cut line 3a that is to be formed.
- the cutter wheel 4 is moved by the moving means 5 and the elastic pressing device 6 that positively presses the cutter wheel 4 against the glass plate 2, and the elasticity of the cutter wheel 4 with respect to the glass plate 2 is moved.
- the control device 7 for controlling the elastic pressing device 6 so as to alternately switch the strength of the pressing force a new (crack) insertion is made deeper, uniformly and cleanly moving the cut line 3
- the glass plate 2 can be formed.
