Abstract
LA EXTRUSION TUBULAR DE UNA SOLUCION DE CELULOSA TERMOPLASTICA NO DERIVADA ALREDEDOR DE UN MANDRIL (26) Y A TRAVES DE UNA CAMARA DE AIRE (24) DE UNA LONGITUD SUPERIOR A 304 MM SE FACILITA CON EL USO DE UN MANDRIL QUE SE PUEDE ALARGAR PARTIENDO DEL MOLDE DE EXTRUSION (12). AL INICIARSE LA EXTRUSION, EL MANDRIL SE ALARGA UNA PEQUEÑA LONGITUD A PARTIR DEL MOLDE. PARA EL FUNCIONAMIENTO DE UN MODO CONTINUADO, EL MANDRIL SE EXTIENDE EN LA TOTALIDAD DE SU LONGITUD PARTIENDO DEL MOLDE. SE MUESTRA TAMBIEN UNA ESTRUCTURA DE MANDRIL QUE FACILITA LA INTRODUCCION DE UN LIQUIDO NO DISOLVENTE EN EL INTERIOR DEL TUBO EXTRUIDO (16), EN UNA POSICION ELEVADA AL COMIENZO DE LA EXTRUSION Y EN UNA POSICION MAS BAJA DURANTE EL FUNCIONAMIENTO EN MODO CONTINUO.
