  • Patent number: 7935299
    Abstract: A method and apparatus for forming a wad of particulate material which may be used in an absorbent article. The apparatus may include a laydown drum having a plurality of vacuum zones, a plurality of fence zones, and a plurality of blow-off zones. The plurality of vacuum zones may be substantially permeable to permit vacuum air to pass through and into the laydown drum. The plurality of fence zones may be substantially impermeable to inhibit air to pass through. The plurality of blow-off zones may be substantially permeable to permit blown air to pass out of and through said laydown drum. The apparatus may also include a deposition chute for depositing particulate material on a web of material in close proximity to the laydown drum. A shield may also be attached to the deposition chute.

  • Patent number: 7906065
    Abstract: A method and apparatus for forming a batt of particulate material which may be used in an absorbent article. The apparatus may include a vacuum zone, an air impermeable fence zone adjacent to the vacuum zone, and an air permeable fence zone adjacent to the vacuum zone. The air permeable fence zone may comprise an ambient air entry conduit in communication with an ambient air exit port. The method may include providing a laydown drum and a first web of material, positioning the first web of material substantially adjacent to the laydown drum, generating a vacuum through the laydown drum, depositing particulate matter onto the first web of material, and rotating the laydown drum.

  • Publication number: 20100258242
    Abstract: A method for making absorbent articles such as diapers and training pants having a pocket for receiving a removable core component is provided. Absorbent articles having removable absorbent core components are further provided. A method for manufacturing an absorbent article comprises providing a wearer facing portion and a garment facing portion, and providing a first absorbent core component with either the wearer facing portion or the garment facing portion. The wearer facing portion and the garment facing portion are associated such that an openable chassis pocket is formed there between, the wearer facing portion and the garment facing portion being separable to create an access opening to the openable chassis pocket for receiving a replaceable absorbent core component.

  • Publication number: 20090157036
    Abstract: A process is claimed for making a composite sheet useful for an absorbent article, the composite sheet comprising a wrinkled, patterned elasticized region that comprises a patterned first sheet and an elastic material, the 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.
