Definitions
- the present invention relates to improvement of glass plate manufacturing technology.
- the conveying step includes a heat treatment step of performing heat treatment on the glass ribbon that has undergone the forming step in the heat treatment zone, a cooling step of cooling the glass ribbon that has undergone the heat treatment step in the cooling zone, and a cooling step using a cutting device. It is preferable that the glass ribbon is cut in the width direction to obtain a glass plate, and the temperature of the glass ribbon is measured at the cooling zone or the downstream side thereof.
- heating devices such as heaters (temperature adjusting devices) are often not installed. Therefore, with the above configuration, the temperature of the glass ribbon can be easily measured without being affected by the heating device, so that the breakage of the glass ribbon can be detected with higher accuracy.
- the forming step is a step of forming the glass ribbon G in the forming zone 11.
- the alarm unit 33 issues an alarm.
