  • Patent number: 6660902
    Abstract: Absorbent article such as a diaper, pant diaper, incontinence guard, sanitary napkin, wound dressing or the like comprising a layer of continuous fibers (9), so called tow, which is bonded in points, spots or lines in a bonding pattern (10), but where the fibers otherwise are substantially unbonded to each other. The layer can either be used as a liquid acquisition layer (5) in the article under the topsheet (2), as a topsheet (12) or as a combined topsheet and liquid acquisition layer (22).
    Type: Grant

  • Patent number: 6511566
    Abstract: Method of producing a fibrous material layer mainly intended to be incorporated in an absorbent article such as a diaper, pant diaper, incontinence guard, sanitary napkin or the like. At least one bundle of continuous filaments, so called tow (12), is opened and the filaments are separated and evened to a layer having the desired fiber distribution, after which the layer is bonded in points, spots or lines in a bonding pattern, but where the filaments otherwise are substantially unbonded to each other.

  • Patent number: 4630055
    Abstract: A dipole arrangement which is located in a sheath,including segments of ejectable dipoles sequentially arranged within the sheath. The dipole can be ejected from the sheath within a short time interval and, subsequent to ejection, will rapidly form a large-surfaced and homogeneous cloud. The segments of the sheath which has a polished inner surface, as viewed in the ejecting direction, evidence an envelopment with a reducing number of windings which consists of a thin metal foil, smooth on both sides thereof, and wherein the dipoles of the enveloped segments, or the only partially enveloped segments, are centripetally pretensioned. The dipoles which are prestressed in the segments act as drive springs for the metal foil which encompass the segment whereby, dependent upon the winding number of the metal foil, there is achieved a time-delayed release of the dipoles.
