Abstract

Procedimiento de doblado y de templado de una vidriera en el que la vidriera llevada a la temperatura de doblado es doblada con la forma deseada en posición horizontal con la ayuda de un marco de conformación (1); la superficie entera de los dos lados de la vidriera doblada (5) es enfriada después bruscamente sobre el marco de conformación (1), en un dispositivo de templado que sigue al de doblado por soplado de aire frío con la ayuda de cajones de soplado provistos de toberas soplantes, caracterizado porque, durante el brusco enfriamiento de la superficie entera de la vidriera, las zonas de los bordes de la vidriera (5) recubiertas por el marco de conformación (1) son sometidas a un soplado suplementariode aire frío por el aflujo adecuado, de las aberturas (4) que atraviesan el marco de conformación (1), de aire comprimido a una presión superiora la presión ambiente que aparece entre los cajones de soplado.
