FIELD: process engineering.
SUBSTANCE: invention relates to textile and light industry. Proposed method comprises laying textile article one onto another, arranging superimposed articles between welding beams, and pressing said beams from top and from bottom. Pressing temperature, pressure and interval are selected so that article coat is not changed into thermoplastic deformable state, ,on one side, and, on the other side, said article does get shrunk. Then, beams are withdrawn. Device with built-in welding device for jointing is composed of rewinder intended for quality control. Final product comprising joint seam represents roofing web, floor coating, composite film.
EFFECT: higher strength.
