Abstract

TOBERA PARA LA REALIZACION DEL PRIMER REVESTIMIENTO DE LAS FIBRAS OPTICAS SEGUN EL METODO POR INMERSION. SE CONSTITUYE POR UN TANQUE PARA LA RESINA Y POR UN CONDUCTO CONICO PUESTO EN COMUNICACION CON EL TANQUE Y QUE PERMITE EL PASAJE DE UNA FIBRA OPTICA EN LA FASE DE HILADURA. LA TOBERA DEBE SER DE ALUMINIO Y AL MENOS LA SUPERFICIE INTERNA DEL CONDUCTO SUFRE UN PROCESO DE OXIDACION ANODICA. SE DIVIDE EN DOS PARTES SIMETRICAS (A, B) QUE SON APTAS PARA ACERCARSE O ALEJARSE POR MEDIO DE UN TORNILLO DE REGULACION (E) Y RESORTES ANTAGONISTAS, ESTANDO PREVISTOS VASTAGOS DE GUIA (F -F ) PARA EVITAR ERRORES EN LA ACCION DE CENTRAR.
