GLASS SHEET MANUFACTURING DEVICE

摘要

A glass sheet manufacturing device 1 provided with a scribing mechanism 2 for forming a scribe line S along the width direction on a surface Ga of a glass ribbon G continuously formed by a down-draw method and conveyed downward, wherein a deformation-imparting mechanism 4 is provided for causing the glass ribbon G carried into the scribing mechanism 2 to curve along the width direction so that the surface Ga side is convex. The glass ribbon G can thereby be carried into the scribing mechanism 2 while being maintained in a shape suitable for forming the scribe line S.
