  • Patent number: 6322547
    Abstract: A method of producing an intermittent elastic web of material. According to the invention, an elongated elastic element (1) is laid-out in a pre-stretched state and in a longitudinal extending wave form and is fastened to a longitudinally extending web (2) such that the web transversely touches or extends beyond the outermost part of wave crests (3) and wave troughs (4) of the wave-shaped elastic element (1), whereafter a longitudinal cut (C) is made in the web so that at least outer parts of wave crests and wave troughs are located on mutually opposite sides of the cut.

  • Patent number: 6273165
    Abstract: A production line for manufacturing absorbent disposable articles includes a conveyor path (3, 14, 15) which moves a web of material through the production line, and a row of devices (1, 4, 5, 6, 7, 8, 9, 11, 12, 13) which are arranged sequentially in the movement direction of the conveyor path and which perform different operations in the manufacture of the absorbent article. The devices are carried by rectangular carrier plates (29, 34, 35, 39, 47) which are attached to vertical posts (17) which, in a framework (16), are placed on the same side of the conveyor path and sequentially in a direction parallel with the movement direction of the conveyor path. The framework includes a plurality of connectors (27, 28) which connect to flowing media delivery lines, such as electric current and compressed air.

  • Patent number: 6187990
    Abstract: The invention relates to absorbent articles, such as diapers and like articles and is concerned with methods for preventing undesirable odors and/or preventing the growth of undesirable microorganisms when the articles are in use, and also provides an absorbent article which can be worn for long periods of time without generating undesirable odors, incurring the risk of infection or having a negative effect on skin. Another object is to amplify the presence in the wearer's urogenital zone of microbiological flora that will assist in preventing the occurrence of urinal tract infections. These objects have been achieved by adding to the absorbent articles microorganisms which exhibit antagonistic properties against present undesirable strains of microorganisms, so as to restrain the growth of these or establishing of new undesirable species.

  • Patent number: 6000102
    Abstract: An apparatus for air-laying of a material in the form of fibers or granules onto a running band. The apparatus includes at least one delimited space arranged at a first surface on an at least partially air-permeable endless running band. A vacuum exists in the space during operation and the band runs successively over the space. This takes place concurrently with air being sucked through the band into the space. At least two rotatable support elements are placed in the space in order to counteract down-bending of the running band. The support elements have a rotational direction generally coinciding with the running direction of the band.

  • Patent number: 5976665
    Abstract: The present invention relates to a liquid-permeable casing sheet (1) for absorbent sanitary articles, such as sanitary napkins, incontinence guards and diapers. According to the invention, the casing sheet (1) includes a first layer (2) which is corrugated across at least a central part of its surface so as to provide a row of mutually parallel waves having wave crests (3) and wave troughs (4), wherein the wave crests form an article contact surface with the wearer's body when the article is in use. The casing sheet also includes rows of through-penetrating openings (6) which extend perpendicularly to the corrugations or waves and each of which opening passes through a wave crest (3). The invention also relates to a method for producing such a casing sheet.

  • Patent number: 5941863
    Abstract: An absorbent article which includes a liquid-permeable outer sheet (1) disposed on a first surface of the article, a liquid-impermeable outer sheet (2) disposed on a second surface of the article, and an absorbent body (3) which is enclosed between the two casing sheets and which includes a receiving space (24) for taking-up body liquid, wherein the space is comprised of at least one cavity or region of lower density than the density of a part of the absorbent body (3) adjacent the receiving space (24) and located generally in the same plane. The article is mainly characterized in that the receiving space (24) is disposed in a storage layer (19) in the absorbent body (3), and in that parts (20,125) of the storage layer (19) adjacent the receiving space (24) include a material which when wetted increases in volume in a direction generally perpendicular to the first surface of the article, whereby the size of the receiving space (24) is also increased in this direction as a result of wetting the article.

  • Patent number: 5935682
    Abstract: A facing sheet (10) for absorbent articles is disclosed in the form of a laminate made up of at least a first layer (12) and a second layer (14). The first layer is intended to face a wearer when the absorbent article is in use and presents a plurality of through holes (16) delimited by an upper perimeter (18) and a lower perimeter (20) to thereby permit liquid to migrate through to the second layer (14). The second layer presents first depressions (22) which are arranged such that the lower perimeter (20) of each hole in the first layer (12) is aligned with an associated depression in the second layer (14). The invention further relates to a method which may be used to produce such a facing sheet.
