An elastic element applicator is provided that is configured to move a section of a continuous strand of elastic element generally about a plane. A first web of material is conveyed in a first web moving direction such that the first web intersects the plane. Then, the applicator is operated to move the elastic element about the plane, thereby applying the section of elastic element onto the first web along a direction generally transverse to the web moving direction and such that the first web draws the continuous elastic strand from the elastic element applicator as the first web is conveyed away from the plane. The elastic element applicator may be in the form of a spin cylinder or bracket that is operated to spin the elastic element about the moving first web, thereby applying the elastic element on the first web.

  • Patent number: 8235959
    Abstract: A process is claimed for making a composite sheet useful as topsheet with one or more openings to receive fecal material useful for an absorbent article, said composite sheet comprising a wrinkled, patterned elasticized region that comprises a patterned first sheet and an elastic material said first sheet being patterned with troughs, that are typically compacter, i.e. of higher density, prior to attachment to the elastic material. The troughs are attached to the elastic material. The resulting composite sheet has a uniform wrinkle pattern. Also claimed are specific absorbent articles. Also claimed are composite sheets with a specific residual strain and peel force value.

  • Patent number: 8226624
    Abstract: Various garments are disclosed which include a body adhesive for attaching the garment to the skin of a wearer. More particularly, the garment can include at least one extensible portion. An adhesive member comprising an adhesive layer and a cover member may be positioned over the extensible portion. The cover member may completely cover the adhesive layer when the extensible portion is in a relaxed condition. When the extensible portion is stretched, however, the cover member may define openings that expose the adhesive layer for adhering the adhesive to a wearer. The garment may comprise, for instance, a diaper, a training pant, a swim pant, a hospital gown, an industrial garment, a glove, a feminine hygiene product, an adult incontinence product, and the like. The adhesive member can be positioned over any suitable extensible portion on the garment.

    Abstract: A pant-like, prefastened, disposable absorbent article having two leg openings which are directly below and visible through a waist opening. The waist opening has a relaxed waist opening measurement or relaxed waist diameter that is greater than a width of a chassis of the absorbent article in a crotch region. As such, the wearer's legs are positioned within and through the leg openings for easy application of the pant-like prefastened, disposable absorbent article. After initial application of the absorbent article, a waist size adjustment feature allows the waist perimeter dimension to be adjusted to conform the waist opening to the waist of the wearer.

  • Publication number: 20120150137
    Abstract: A film that contains a thermoplastic composition having a substantial portion of a renewable, natural starch polymer, and yet is elastic and exhibits good strength properties, is provided. Although starch is normally chemically incompatible with most elastomeric polymers due to their different polarities, the present inventors have discovered that phase separation may be minimized by selectively controlling certain aspects of the film, such as the nature of the elastomeric polymer and the starch polymer, and other film components, the relative amount of the film components, and the process for making the film.
