Abstract: The present invention relates to a method of manufacturing absorbent articles provided with fastener means that include locking elements. According to the invention the method comprises the step of delivering a first web of material (4) to an absorbent article manufacturing machine; separating discrete pieces of material (7) from the first web (4); applying the discrete material pieces (7) to a second web of material (5), for instance a web of material which is to form an absorbent article casing sheet; and thereafter forming locking elements in the regions of the discrete material pieces (7).

Abstract: A material laminate (1) with a planar dimension and a thickness direction perpendicular to the planar dimension, comprises a first liquid-permeable fibrous material layer (2) and a second liquid-permeable, porous and resilient material layer (3), with at least one of the material layers (2, 3) including thermoplastic material and the two material layers (2, 3) being mutually connected by the material laminate (1) exhibiting bonding sites (4) within which the thermoplastic material has been caused to at least partially soften or melt and thereby bond together the two material layers (2, 3). The bonding areas are arranged in two or more groups (5) with at least two bonding sites (4) in each group (5), with the greatest relative distance between two bonding sites (4), which are situated adjacent to each other, in a particular group (5) being less than the shortest distance between the group (5) and its closest adjacent group (5), as a result of which the material laminate (1) exhibits bond-free areas (6) between the bonding sites (4) within each bonding group (5) which have a higher density than bond-free areas (9) of the material laminate which are situated between the bonding groups (5). The laminate may be used as an outer layer on absorbent products such as nappies, panty nappies, incontinence shields, sanitary towels or bandages.

Abstract: In a method and device for applying a thread to a moving substrate, a thread is continuously dispensed to a pick-up point adjacent to the point of contact of two rotating wheels (2, 3) that are inclined towards each other. The peripheries of the wheels have fingers (7) which hook the thread and move it to one side or the other as the wheels rotate, and then deposit the thread extended between the fingers 180° from the pick-up point. Long spaces between the fingers (7) on one wheel or the other make it possible to lay the thread longitudinally (8b) or in a long diagonal line instead of merely in a lateral zigzag pattern. The method and device may be used to make an absorbent article, such as a diaper.

Abstract: An oblong absorbent article that includes a liquid-impermeable bottom sheet, and upper liquid-permeable sheet and an absorbent body disposed between these sheets, and on each side of the longitudinal center line of the upper sheet at least one longitudinal elastic liquid barrier having at least the free edge treated with a non-adhesive sealing medium which partly fills out the pores formed between the free edge and the abutment surface on the wearer, and/or which, when the article is donned, increases around said abutment surface, the wetting angle of the liquid to the skin. An absorbent article that includes an essentially liquid-impermeable top sheet above an absorbent body enclosed between an upper liquid-permeable sheet and a liquid-impermeable sheet, the top sheet being provided with elastic for shaping the article to the wearer's body and incorporating apertures intended to register with the anus and the urethra orifice of the wearer in use, around which apertures elastically puckered sealing edges are disposed, at least one sealing edge being coated with the sealing medium.

Abstract: A method of improving the sealing effect against the skin of an absorbent article comprising an absorbent body disposed between liquid impermeable and liquid permeable sheets, such article having either longitudinally extending liquid barriers 28 on each side of the centre line of the permeable top sheet which have free elastic edges for contacting the skin or having a further liquid impermeable, body-contacting sheet with anal and urethral apertures around which elastic sealing edges are provided, comprises increasing the capillary pressure of the pores of said barriers/sealing edges by causing the absolute value of the negative product 2γcos#m/r to increase. This is achieved by decreasing the pore radius r and/or by increasing the wetting angle #, γ being the surface tension of the liquid to be absorbed and cos#m being the weighted mean value of cos#. A diaper or incontinence guard having such improved properties is thereby provided.

Abstract: An absorbent article includes a front part, a rear part and an intermediate crotch part and also an absorbent body enclosed between the outer liquid-impermeable casing sheet and an inner liquid-permeable casing sheet, and longitudinal flaps located on respective sides of the longitudinal symmetry axis of the article and that extend transversely in towards the axis, and further including longitudinal elastic elements which extend along those edges of the flaps that face toward the longitudinal symmetry axis. The absorbent body is divided into a central part and two side parts at least in the crotch part by folding indications which are located on respective sides of the longitudinal symmetry axis in front and rear sections and which diverge relative to one another up to the side edges of the absorbent body. The side flaps are joined to the outer casing sheet along its longitudinal edges; and each of the side flaps extends from a point in the crotch part on the inside of the article inwardly toward the longitudinal symmetry axis (AA) while decreasing in distance from the axis towards the front part and the rear part respectively up to a point in respective front and rear parts.

Abstract: PCT No. PCT/SE96/00117 Sec. 371 Date Sep. 24, 1997 Sec. 102(e) Date Sep. 24, 1997 PCT Filed Feb. 1, 1996 PCT Pub. No. WO96/23465 PCT Pub. Date Aug. 8, 1996A method of elastifying a non-woven or plastic jacket of a pants-type article in its unassembled hour-glass form, arranged end-to-end in a longitudinal web, includes the steps of stretching a web length of elastic net, film or elastomeric non-woven material, which is rectilinear in its unstretched state, transversely but not longitudinally at the two end portions (113) which will form the waist, stretching the length of elastic net, film or elastomeric non-woven material longitudinally but not transversely at the intermediate crotch portion (14) therebetween, whereby the net or film will naturally assume the desired hour-glass shape of the jacket to be elastified, then bonding the stretched net or film in its hour-glass shape to the jacket (5).
