ABSTRACT OF THE DISCLOSURE. To prevent uncontrolled movement of the end portion of a renewal web to be applied against the trailing end of a previously used web, typically of paper, to be passed through a rotary printing machine, the end of the renewal web is cut at a slant to form a cut edge (3) extending between 60°to 80° with respect to the direction of roll-off of the renewal web. A coupling strip is then placed over the cut edge, the coupling strip (4) having a first adhesive zone (5) adhered to the top layer of the renewal web, with the non-adhesive central zone overlying the edge (3), and a second adhesive zone overlying the outer surface of the next layer adjacent the outer edge. An adhesive (5", 10, 11) is then applied to the region of the outer layer (2) of the renewal web, starting, for example, from the perforating line and extending over the surface of the renewal web.
