Abstract

SE PRESENTA UN METODO PARA MANUFACTURAR UNA PROFORMA PARA SU FORMACION EN UNA FIBRA OPTICA QUE COMPRENDE EL POSICIONAMIENTO DE UNA VARILLA (10) DENTRO DE UN MANGUITO (42) PARA FORMAR UN MONTAJE EN EL CUAL HAYA UN ESPACIO ANULAR (26) ENTRE LA VARILLA Y EL TUBO, Y EL COLAPSO DEL TUBO SOBRE LA VARILLA PARA FORMAR UNA PROFORMA DE SECCION DE CORTE SOLIDA. EL PASO DE COLAPSADO COMPRENDE EL SELLAMIENTO DEL ESPACIO ANULAR (26) EN UN EXTREMO (30) DEL MONTAJE Y LA APLICACION DE SUCCION AL ESPACIO ANULAR DESDE EL OTRO EXTREMO DEL MONTAJE. EL ESPACIO ANULAR (26) EN DICHO EXTREMO (30) SE SELLA COLOCANDO EL EXTREMO DEL TUBO (28) EN EL EXTREMO SOBRE UNA NERVADURA ANULAR (22) DE LA VARILLA Y FUNDIENDO EL TUBO CON LA VARILLA.
