Abstract: The starting material consists of a multistrand elastic tape (7) which is fed by the apparatus (11) and then separated by the successive separators (20, 24, 30, 31, 32, 33) into two arrays (35, 36) of four individual elastic strands. Each individual strand passes into a longitudinal groove of an adhesive application unit (37, 38), the strands passing out completely coated with hot melt liquid adhesive at high temperature. Adhesive bonding to the flexible sheet (1) moving in the direction of the arrows (2) is effected as soon as contact is made with the said sheet.A diaper pantie is obtained which on each side of the absorbent pad has a plurality of elastic strands disposed side by side.

Abstract: A diaper includes a flexible outer film impermeable to liquids and, on the inside surface of the outer film, longitudinal strips of adhesive and an absorbent pad. The pad has longitudinal edges set back from longitudinal edges of the outer film and transverse edges set back from transverse edges of the outer film. A flexible inner film permeable to liquids covers the inside surface of the outer film and the absorbent pad. It is adhesively bonded to the outer film in the area of contact between the films around the pad. Longitudinal elastic members are adhesively bonded while under tension to the outside surface of the outer film, along a central part of its longitudinal edge portions. The diaper also includes attachment means for fastening it around the body of the wearer and two flexible film tapes on the outside surface of the outer film over all its length and over a width that is greater than the width of the elastic members. These tapes enclose the elastic members.
