WIPO Patent Application WO/2010/074091
Kind Code:
A1
Abstract:
A method of cutting a brittle-material plate is provided by which the brittle-material plate can be cut into a desired planar shape through automatic machine production without complicating the device. Also provided are a window glass for vehicles which is obtained by the cutting method and a device for cutting a brittle-material plate.
The method of cutting a brittle-material plate comprises: a first step in which a scribe line (L2) is formed in a surface (G1) of a brittle-material plate (G); and a second step in which the position (A) where the surface (G1) of the brittle-material plate (G) is irradiated with laser light is relatively moved along the scribe line (L2) to cut the brittle-material plate (G) ahead of the irradiation position (A) with respect to the moving direction.
