Abstract

L'invention concerne des procédés et systèmes pour la mise en forme automatisée d'une feuille de verre. Les procédés consistent à préchauffer le verre, bomber le verre à travers un chauffage sélectif à faisceau focalisé par l'utilisation d'une ultra-haute fréquence, d'une onde électromagnétique à haute puissance et de processus mis en uvre par ordinateur utilisant des données (de position) thermiques et de forme obtenues en temps réel et refroidir la feuille de verre pour produire une feuille de verre appropriée pour une utilisation dans des véhicules aériens et spatiaux.
