Abstract

A method of butt-joining metal tapes coated on one or both sides with a film of thermoplastic polymer material. The film is detached from an end portion of each tape (1A 1B) by immersion in a solvent at its boiling point. The detached film is removed and the ends of the two tapes welded together. A film (17, 18) of high-density polyethylene and ionomer resin is applied to the stripped area and bonded thereto by the application of heat and pressure. Device for implementation of the method.
