CUTTING DEVICE FOR BRITTLE MATERIAL, CUTTING METHOD FOR BRITTLE MATERIAL, AND MANUFACTURING METHOD FOR CUT BRITTLE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a cutting device for brittle material and a cutting method for brittle material that can achieve full-body cutting not through a fold breaking process without stopping conveyance even when a material is thick.SOLUTION: According to the present invention, there is provided a cutting device 1 for a brittle material 2 comprising: a conveyance mechanism 20 for conveying the brittle material 2; an infrared-ray line heater 10 for irradiating a region that the brittle material 2 conveyed by the conveyance mechanism 20 passes through with concentrated infrared rays linearly in a direction Y perpendicular to a conveyance direction X of the brittle material 2; and a heater moving mechanism 30 for moving the infrared-ray line heater 10 in the same direction and at the same speed with the conveyance of the brittle material 2 by the conveyance mechanism 20.SELECTED DRAWING: Figure 1
