Abstract

PROCEDE DE FABRICATION D'UN CABLE DE TELECOMMUNICATIONS COMPRENANT UN FAISCEAU DE CONDUCTEURS AU MOINS UNE GAINE DE REVETEMENT QUI ENTOURE LES CONDUCTEURS ET UNE MATIERE EN POUDRE EXPANSIBLE INTERPOSEE ENTRE LA GAINE ET LES CONDUCTEURS. CE PROCEDE CONSISTE A FAIRE AVANCER LES CONDUCTEURS 2 DANS UNE CAVITE TRONCONIQUE 18 EN LES MAINTENANT SEPARES, A FAIRE AVANCER UNE MATIERE EN POUDRE SOUS PRESSION SUIVANT UN TRAJET HELICOIDAL TOUT EN LA POUSSANT ENTRE LES CONDUCTEURS QUI PASSENT DANS LA CAVITE TRONCONIQUE ET A REVETIR LES CONDUCTEURS D'UNE GAINE A LA SORTIE DE LA CAVITE. L'INVENTION PERMET DE REMPLIR DE POUDRE L'ESPACE COMPRIS ENTRE LES CONDUCTEURS MEME SI L'ALIMENTATION PAR LA TREMIE 19 EST INTERROMPUE ET ELLE EMPECHE LA FORMATION DE CANAUX DANS LES MASSES DE POUDRES ACCUMULEES PRES DE LA SORTIE.
