Abstract

L'invention concerne la trempe de feuilles de verre et, plus précisément, le refroidissement de feuilles de verre ramollies par la chaleur, avec une rapidité suffisante pour établir un profil de tension à travers l'épaisseur du verre, profil dont l'amplitude est suffisante pour tremper les feuilles de verre avec un minimum de déformation superficielle, en un traitement au cours duquel des feuilles de verre plat sont transportées en prenant appui sur un lit gazeux 12.
