Abstract

The invention relates to a method and a device for detecting a moving glass sheet heated to a temperature above its softening point. A jet of pressurised gas, in particular compressed air, is sent through the path which the sheet of glass takes, and the variation in pressure of the jet when the latter is intersected by the sheet of glass is detected. <IMAGE>
