Abstract

METODO PARA CONFORMAR UNA LAMINA DE VIDRIO REBLANDECIDA POR EL CALOR. LA LAMINA REBLANDECIDA MEDIANTE RODILLOS (18) AL PUESTO DE CONFORMACION (16). EL MOLDE INFERIOR (34) POSEE UNAS RANURAS (24) QUE LE PERMITEN EL DESPLAZAMIENTO VERTICAL HACIA EL MOLDE SUPERIOR (36). ENTRE ESTOS DOS MOLDES CONFORMAN LA LAMINA. EL MOLDE SUPERIOR POSEE UN METODO DE SUJECION POR VACIO Y SE DESPLAZA DESPUES DEL CONFORMADO A UNA UNIDAD DE ENFRIAMIENTO (14) MEDIANTE AIRE A PRESION QUE SALE POR LOS CONDUCTOS (52, 55). LA LAMINA ES TRASNPORTADA AHORA MEDIANTE RODILLOS (74).
