Abstract

LA INVENCION SE REFIERE A UN PROCESO Y A UN DISPOSITIVO DE ABOMBADO-TEMPLE SEGUN EL CUAL LAS LAMINAS DE VIDRIO SON CALENTADAS A LA TEMPERATURA DE ABOMBADO EN UN HORNO HORIZONTAL Y A CONTINUACION SON ABOMBADAS CON LA FORMA DESEADA POR PRENSADO ENTRE UNA FORMA DE ABOMBADO SUPERIOR PLENA Y UNA FORMA INFERIOR ANULAR QUE SIRVE TAMBIEN DE SOPORTE A LA LAMINA ABOMBADA EN EL PUESTO DE TEMPLE DONDE LAS LAMINAS ABOMBADAS SE ENFRIAN POR SOPLADO DE AIRE FRIO, PRESENTANDO LA PARTE INFERIOR UNA SUPERFICIE DE ABOMBADO CONTINUA. EN EL PUESTO DE TEMPLE, LA LUNA SE ELEVA POR MEDIOS QUE ACTUAN LOCALMENTE Y A CONTINUACION SE LLEVA A CABO LA OPERACION DE SOPLADO EN ESTA POSICION ELEVADA.
