Abstract

SE DESCRIBE UN APARATO (20, 120) PARA FORMAR UNA HOJA G DE VIDRIO CALIENTE QUE INCLUYE UN MOLDE AL VACIO (22, 22A, 122, 122A) QUE TIENE UNA SUPERFICIE COMPLETA (24, 24A, 124, 124A) JUNTO A LA QUE UN MOLDE PERIFERICO (26, 26A, 126, 126A) APRIETA LA PERIFERIA DE LA HOJA DE VIDRIO Y CON LA QUE AL MENOS UNA RESERVA AL VACIO (32, 33) SE COMUNICA EN EL INTERIOR DE LA PERIFERIA DE LA HOJA DE VIDRIO SELLADA PARA FORMAR LA HOJA DE VIDRIO CON LA FORMA DE LA SUPERFICIE DEL MOLDE AL VACIO. EL VALVULAJE (38) DEL SISTEMA AL VACIO (28) ES PREFERIBLEMENTE OPERABLE PARA PROPORCIONAR EL IMPULSO AL VACIO EN DOS FASES CON UN GRADO INICIAL LIMITADO DE VACIO Y UN GRADO SUPERIOR DE VACIO POSTERIOR COMUNICANDOSE PRIMERO CON UNA RESERVA AL VACIO (32) Y POSTERIORMENTE CON OTRA RESERVA AL VACIO (33). DIFERENTES REALIZACIONES DEL MOLDE AL VACIO TIENEN LA SUPERFICIE DEL MOLDE AL VACIO MIRANDO HACIA ADELANTE Y HACIA ATRAS CON FORMAS CONCAVAS Y CONVEXAS. LAS FORMAS DE HOJAS DE VIDRIO INCLUYEN ELEMENTOS DE LINEA RECTA COMO CURVATURAS CILINDRICAS Y CONICAS ASI COMO FORMAS QUE INCLUYEN CURVATURAS EN DIRECCIONES TRANSVERSALES Y MEDIANTE ESTA FORMACION DE IMPULSOS AL VACIO PUEDEN SER PROVISTAS DE FORMA EFECTIVA CURVATURAS INVERSAS.
