Abstract

EL INVENTO SE DIRIGE HACIA LA FABRICACION DE CUERPOS HUECOS DE PLASTICO EN PROCEDIMIENTO DE SOPLADURA QUE TRABAJA CON PRECONFORMADOS COMPUESTOS DE VARIAS CAPAS DE DIFERENTES MATERIALES (PROCEDIMIENTO DE CO-EXTRUSION). MEDIANTE EL INVENTO DEBE PRODUCIRSE UNA CABEZA DE TUBO FLEXIBLE ACUMULADORA ADECUADA PARA EL PROCEDIMIENTO DE CO-EXTRUSION, EN LAS QUE LAS CAPAS SE MANTIENEN HASTA LA EXPULSION FUERA DE LAS TOBERAS DE SU LUGAR ADJUDICADO Y COLOCACION SOBRE LAS LONGITUDES TOTALES. AQUI SE PROPONE QUE EN UNA CABEZA ACUMULADORA CON CANALES DE ALIMENTACION (3) EN FORMA DE ANILLO, COLOCADOS COAXIALMENTE QUE ALIMENTAN UN EXTRUIDO (2), QUE FORMAN UNA CAPA DEL TUBO FLEXIBLE, EN UNO DESEMBOCA EL CANAL ANULAR (5) QUE FORMA UN LAMINADO, ESTE CANAL ANULAR (5) ESTA ENTRE LAS PAREDES DIRIGIDAS UNA HACIA OTRA DE UNA FALDA DE OBTURACION (6) INTERIOR EN FORMA DE ARO Y UNA FALDA DE OBTURACION (8) EXTERIOR EN FORMA DE ARO, SOBRE LAS QUE ESTAN COLOCADAS SUPERFICIES DESVIADAS UNA HACIA OTRA PARA TRANSFERIR EL LAMINADO DE LA CAMARA DE ACUMULACION (21) DE UN EMBOLO ANULAR (13) INTERIOR Y EXTERIOR (13 O 14).
