<p>The invention concerns a method for curving and tempering a glass sheet, which consists in curving the glass sheet into the desired shape by means of a forming frame (1). The same forming frame (1) is used for chilling the whole surface of both sides of the curved glass sheet in a tempering station which comes immediately after the curving station by blowing cold air by means of blow boxes equipped with blow nozzles. During the chilling of the whole surface, the glass sheet edge zones resting on the forming frame (1) are subjected to an additional cold air spray by the adequate supply of compressed air into the openings (4) passing through the forming frame (1).</p> |
