Abstract

METODO PARA FABRICAR UNA LAMINA CONTINUA DE VIDRIO DE ESPESOR INFERIOR AL DE EQUILIBRIO. SE HACE PASAR EL VIDRIO PRIMERO POR UNA ZONA DE RELAJACION Y LUEGO POR UNA ZONA DE ESTIRADO LONGITUDINAL Y LATERAL, EN LA QUE SE REDUCE EL ESPESOR DEL VIDRIO, ANTES QUE EL VIDRIO SE HAYA ESTIRADO LO BASTANTE, PARA HACERSE DIMENSIONALMENTE ESTABLE. LA ZONA DE RELAJACION SE HALLA PROXIMA AGUAS ABAJO DEL PUNTO EN EL CUAL EL VIDRIO EN FUSION SE SUMINISTRA A UNA PRIMERA EXTEMIDAD DE UN BAÑO DE METAL EN ESTADO DE FUSION. POR ULTIMO, SE RETIRA LA CINTA DE VIDRIO DIMENSIONALMENTE ESTABLE, EXTRAYENDOLA DE UNA SEGUNDA EXTREMIDAD DEL BAÑO DE METAL EN ESTADO DE FUSION.
