Glass breakage detection method, sheet glass manufacturing method, and glass cutting device

摘要

Provided is a method for detecting glass breakage in which a plurality of sensors 5 capable of detecting glass are arranged along the width direction of band-shaped glass G1 that moves in the lengthwise direction in a cutting step P for cutting out plate glass by cutting said band-shaped glass G1 in the width direction thereof. It is determined on the basis of the detection results of the sensors 5 whether there is breakage in the glass.
