Abstract

L'INVENTION CONCERNE UN PROCEDE ET UN APPAREIL DE CINTRAGE A FROID DESTINES A REALISER DES CANALISATIONS COURBES COMPORTANT UN TUBE EXTERNE QUI CONTIENT UN TUBE INTERNE DONT LE CINTRAGE EST EFFECTUE EN MEME TEMPS QUE LE CINTRAGE DU TUBE EXTERNE. LE PROCEDE SELON L'INVENTION EST REMARQUABLE EN CE QU'IL CONSISTE A ASSURER LE CINTRAGE DU TUBE EXTERNE 1 AU MOYEN D'UN MANDRIN 3 MUNI D'UN EVIDEMENT LONGITUDINAL 3A QUE L'ON DEPLACE LE LONG DU TUBE INTERNE 2 POUR GUIDER AINSI LE CINTRAGE DE CE DERNIER. L'INVENTION CONCERNE TOUTES LES CANALISATIONS A DEUX TUBES INSERES L'UN DANS L'AUTRE, COAXIAUX OU NON, TELLES LES MANCHES DE DISTRIBUTION DE CARBURANT.
