Abstract
Monitoring the temperature profile of a series of glass sheets heated while conveyed through a furnace where they are heated preparatory to their rapid cooling required for tempering. Representative temperatures are taken at selected portions of the upper and lower surfaces of selected sheets to determine the temperature difference between the top and bottom surfaces and an indication of the temperature profile transverse to the direction of glass sheet movement. The temperature monitoring system may also include an additional temperature measuring station at a suitable position in a quenching zone where the heated glass sheets are rapidly cooled.
