Abstract

La invención se relaciona con un dispositivo y un método para flexionar y enfriar hojas de vidrio que comprende flexionar las hojas de vidrio por gravedad sobre un soporte por gravedad durante el cual el vidrio descansa sobre el soporte por gravedad en la zona periférica constituida de los 50 mm a partir del borde de su primera cara principal, luego se separa el vidrio del soporte por gravedad cuando el vidrio está a más de 560°C, luego se enfría el vidrio durante lo cual su primera cara principal está libre de cualquier contacto en su zona periférica, entre una temperatura denominada temperatura homogénea superior, de al menos 560°C y una temperatura denominada temperatura homogénea inferior, de como máximo 500°C, denominada margen de temperatura crítico, la zona de la primera cara principal a una distancia mayor a 200 mm a partir del borde estando a una temperatura al menos igual a la de la zona periférica al momento cuando la zona periférica alcanza la temperatura homogénea superior.
