METHOD FOR SCRIBING TEMPERED GLASS PLATE AND METHOD FOR CUTTING TEMPERED GLASS PLATE

摘要

Provided is a method of scribing a tempered glass sheet, which involves forming a scribe line (S) for cutting a tempered glass sheet (G) with a scribing wheel (H) moving along a preset cutting line (CL) while pressing a front surface (Ga) of the tempered glass sheet (G), the method including: starting the forming of the scribe line (S) by causing the scribing wheel (H) to climb onto an edge portion (Ea), which is one of edge portions of the tempered glass sheet (G) positioned on one end side of the preset cutting line (CL); and finishing the forming of the scribe line (S) by moving the scribing wheel (H) to a position where a vicinity of an edge portion (Eb), which is another of the edge portions of the tempered glass sheet (G) positioned on another end side of the preset cutting line (CL), remains as an unscribed portion.
