Title (EN) PROCESS FOR BUTT-JOINING OF TWO SUCCESSIVE METAL STRIPS COATED WITH A THERMOPLASTIC POLYMER FILM AND DEVICE FOR CARRYING OUT SUCH PROCESS
(FR) PROCEDE DE RABOUTAGE DE DEUX FEUILLARDS SUCCESSIFS D"UN METAL REVETU D"UN FILM DE POLYMERE THERMOPLASTIQUE ET DISPOSITIF POUR LA MISE EN OEUVRE
Abstract:
(EN) Process for butt-joining of two metal strips coated on at least one face of a thermoplastic polymer film. The film is detached on a certain length from the end of each strip (1 A, 1B) by immersion into a boiling solvent and removed, the ends of the two strips are welded, a film of high density polyethylen and ionomer resin (17, 18) is applied onto the stripped surface and is adhered by pressure heating; device for carrying out the process. Application to butt-joining of the outer return wire of telecommunication submarine cables.
(FR) Procede de raboutage de deux feuillards d"un metal revetu sur au moins une face d"un film de polymere thermoplastique. On decolle le film sur une certaine longueur de "extremite de chaque feuillard (1A, 1B) par immersion dans un solvant bouillant et l"enleve, on soude les extremites des deux feuillards, on applique sur la zone denudee un film (17, 18) de polyethylene haute densite et resine ionomere et l"y fait adherer par chauffage sous pression; dispositif de mise en oeuvre. Application au raboutage du conducteur de retour externe de cables sous-marins de telecommunications.
