Abstract

DISPOSITIF DE FABRICATION, PAR EXTRUSION, D'UN FIL METALLIQUE SOUS GAINE THERMOPLASTIQUE. LE FIL METALLIQUE 1 SE DEPLACE DANS UN CONDUIT 2 DE FILIERE D'EXTRUSION DE LA GAINE. POUR FAIRE VARIER LA POSITION DU FIL DANS SA GAINE DES MOYENS SONT PREVUS POUR MODIFIER L'UN PAR RAPPORT A L'AUTRE LES DEBITS DE MATIERE THERMOPLASTIQUE DANS DEUX ZONES DISTINCTES D'UNE MEME SECTION DROITE DU CONDUIT DE FILIERE D'EXTRUSION. LA MODIFICATION DES DEBITS EST OBTENUE EN FAISANT VARIER, DANS LESDITES ZONES, LA TEMPERATURE DE LA MATIERE THERMOPLASTIQUE. APPLICATION: FABRICATION DE FILS DU RESEAU TELEPHONIQUE.
