Abstract
LA INVENCION TRATA DE UN PROCEDIMIENTO Y DE INSTALACIONES PARA CURVAR PLACAS DE CRISTAL. LAS PLACAS DE CRISTAL (9) SE CALIENTAN A LA TEMPERATURA DE CURVATURA EN UNA POSICION HORIZONTAL EN UN HORNO CONTINUO (1) Y SE PRESIONAN EN UN POSTE DE CURVATURA (4) ADYACENTE AL HORNO CONTINUO (1) POR MEDIO DE UN CUADRO ANULAR CONTRA UNA FORMA DE CURVATURA DE SUPERFICIE PLANA (40). DURANTE LA PRESION ENTRE EL CUADRO ANULAR Y LA FORMA DE CURVATURA DE SUPERFICIE (40), LAS PLACAS DE CRISTAL (9) SON PRESIONADAS CONTRA ESTA FORMA DE CURVATURA DE SUPERFICIE (40), EN LA ZONA SITUADA EN EL INTERIOR DEL CUADRO ANULAR, POR LA PRESION ESTETICA DE UN GAS CALIENTE BAJO PRESION, LA PRESION ESTATICA DEL GAS ESTA PRODUCIDA EN UNA CAMARA (32) CUYA CARA SUPERIOR (33) ESTA DELIMITADA POR EL CUADRO ANULAR Y ESTA CERRADA POR LA PLACA DE CRISTAL (9) APLICADA DE MANERA HERMETICA CONTRA ESE CUADRO ANULAR. LA INVENCION PERMITE PROPORCIONAR VIDRIOS CURVADOS, QUE PUEDEN TENER FORMAS COMPLEJAS CON UNA BUENA PRECISION DE CONTORNOY UNA BUENA CALIDAD OPTICA.
