Abstract
The invention relates to air tempering of glass in flat tempering installations. It proposes blowing air, particularly at sonic speed, with nozzles, preferably tubular, slightly distant from the glass, exhibiting the maximum loss of pressure at their free end close to the glass. It makes possible the tempering, under economically advantageous conditions, of glass sheets having thicknesses less than 2 mm and all the more so, glass sheets having greater thicknesses, which can be used as glasses, particularly windshields, for motor vehicles.
