Abstract:
1. A method for manufacturing pant-type articles, said method comprising the steps of: a. providing a first web, said first web having a primary extension in the machine direction, first and second faces and a first edge and a second edge, said first and second edges extending in the machine direction; b. providing a second web, said second web also having a primary extension in the machine direction, first and second faces and a first edge and a second edge, said first and second edges extending in the machine direction; c. applying a first adhesive to at least a portion of the first face of said first web; d. applying at least one elastic thread on at least the portion of said first face of said first web which comprises said first adhesive: wherein said at least one thread is applied in a pattern, said pattern oscillating in the cross-direction and extending in the machine direction, such that the pattern extends over the first edge of the first web to form loops in said elastic thread which project in the cross-direction from said first edge of said first web; e. securing the loops in a loop retaining element comprising at least one first and at least one second resilient belt which are located adjacent the first edge of said first web; f. applying the first face of said second web on the first face of said first web, and fixing said first and second webs together such that said at least one elastic thread is partly sandwiched between the first faces of said respective first and second webs; g. cutting the elastic thread substantially at each point at which the elastic thread crosses the first edge of said first web such that the loops become detached from the first web so as to thereby provide an elasticated web having discontinuous elastic threads, said elasticated web having first and second edges extending in the machine direction and said discontinuous elastic threads being sandwiched between the first faces of the respective first and second webs and extending to the first edge of said elasticated web; h. arranging first and second such elasticated webs adjacent one another and in a spaced relationship such that the first edges of each of said elasticated webs are located closest to one another and aligned substantially parallel to one another; said first and second elasticated webs being synchronised such that each discontinuous elastic thread in the first elasticated web is located opposite the corresponding discontinuous elastic thread in the second elasticated web; i. placing at least one of a fourth web or an absorbent packet so as to overlie at least a portion of at least one of the first or second elasticated webs, and fixing at least one of said fourth web or said absorbent packet to both first and second elasticated webs; j. cutting out leg regions of one or both elasticated webs and, if present, said fourth web; each leg region being defined substantially within said elasticated webs by the discontinuous elastic threads; k. folding the co-joined elasticated webs along a fold-line, so that the second edges of each elasticated web become arranged substantially adjacent one another and substantially parallel, with at least one of the fourth web located on the outside of the fold or the absorbent packet located on the inside of the fold; l. joining the first and second elasticated webs to each other along cutting lines, said cutting lines extending substantially in the cross-direction from the second edges of each elasticated web to the fold-line, said cutting lines being located substantially at the point at which the at least one discontinuous elastic thread is located furthest from the first edge of each elasticated web; to form side-seams; and m. cutting each elasticated web, and, if present, the fourth web, along the cutting lines such that first and second elasticated webs remain joined on either side of the cut, so as to provide pant-type articles.
