Fabrication method for disposable articles and a liquid-absorbing disposable article

Claim 1

A continuous method for the fabrication of disposable articles designed to absorb liquids comprising the steps of (a) cutting a continuous impermeable foil (45) into first and second continuous strips (45a,45b) and in its median zone along a lay-out to provide a cut-out area comprising a series of straight-line sections (T 1 , T 2 , T 3 . . . ) parallel to the longitudinal axis (XX') of the foil, whereby said straight-line sections are alternatingly staggered on either side of said axis with the distance between two consecutive sections located on the same side of the foil axis exceeding the length (l) of the sections, with the ends of said sections being connected by connecting sections (T 12 ', T 23 '. . . ) intersecting the foil axis at their center, said first strip (45b) being laterally shifted by a distance slightly less than the distance (d 1 ) between the straight line section and the longitudinal axis, and then longitudinally by a length equal to the cutting repeat (T) so that two straight line sections are symmetrical with respect to said axis, with said second strip (45a) following a longer path than the first (45b) and exceeding the length of said first strip by the repeat (T) of the cut-out; (b) depositing said first and second strips on an absorbing material in such a manner whereby open zones bounded by said strips are located in the central region of said absorbing material; and (c) cutting the sheath so obtained into individual articles.
