  • Patent number: 6328725
    Abstract: The invention relates to a method of producing reclosable absorbent garments, in particular absorbent pants, and to the absorbent garments obtainable by said method. Starting from a continuous web (1) of absorbent articles attached side-by-side and with a line of weakening (6) arranged between adjacent articles, a first strip (8) comprising releasably attachable material is applied across the line (6) at one edge (25) of the web. A second strip of flexible material is also applied across the line (6) at the other edge (26) of the web. The web is then folded longitudinally to form a series of closed, joined adjacent articles. The adjacent articles are then partially separated at said line (6) but without rupturing said strips (8, 13), so as to provide a free zone (15) between said strips (8, 13) and the adjacent separated edges of each article. The strips (8, 13) are then joined together across the free zone (15) to form a plurality of joined garments.

  • Patent number: 6179820
    Abstract: An absorbent article'such as a pair of absorbent pants, a nappy, an incontinence protection article or the like having a substantially elongated shape is provided. The absorbent article includes a front waist region, a rear waist region and a crotch region positioned therebetween having two leg edge-portions. The absorbent article includes an inner fluid-permeable layer, a fluid-barrier layer and an absorbent core enclosed therebetween. The article also includes elastic elements which are arranged along four different paths. One segment of each path follows at least a portion of a leg edge-portion and the paths together enclose a collection region positioned between the article's leg edge-portions, which region, under the influence of the elastic elements, bulges and forms a fluid-collecting basin.
