Abstract

APARATO ALIMENTADOR DE ELEMENTO FILIFORME QUE SE ALOJA COMO REFUERZO EN EL INTERIOR DE TUBOS FLEXIBLES CONFORMADOS EN MAQUINAS EXTRUSADORAS POR AIRE O AL VACIO. SE ACOPLA AL CABEZAL EXTRUSOR DE LA MAQUINA (1, 6) Y PRESENTAN UNA PIEZA TUBULAR (4) QUE COOPERA A LA ALIMENTACION DESDE EL INTERIOR DE LA MAQUINA, DEL ELEMENTO FILIFORME (3), MUY RESISTENTE A LA TRACCION, ANTES MENCIONADO, EL CUAL PASA POR DENTRO DEL CABEZAL HACIA EL INTERIOR DE UN CONDUCTO-EJE QUE ATRAVIESA LONGITUDINALMENTE LA CAMARA DE EXTRUSION, CUYO ELEMENTO FILIFORME SALE POR EL INTERIOR DEL TUBO FLEXIBLE (C) QUE SE HA CONFORMADO.
