  • Patent number: 6652693
    Abstract: The present invention provides a distinctive method and apparatus (20) for forming an article which includes one or more selectively configured strands of material. In particular aspects, the invention can provide a method and apparatus for wrapping a strand of material with a selected filament, and desirably, the filament can be an adhesive filament. The technique of the invention can include a moving of a strand of material (22) at a selected speed along an appointed machine-direction (34). A substantially continuous filament (24) can be directed onto the strand of material (22) along an oscillating filament path (26) to form a plurality of filament threads (28) extending from opposed lateral side regions (30) of the strand of material (22). An air stream (32) is directed to operatively wrap the filament threads (28) around the strand of material (22).

  • Patent number: 6416697
    Abstract: A method and apparatus for forming an article (94) includes a moving of a forming surface (22) through an operative forming chamber (24) along a forming path length (40). A first fibrous stratum (26) of fiber material (96) can be deposited onto the forming surface (22), and the first fibrous stratum (26) can have a first stratum thickness (28). A first quantity of a first superabsorbent material (30) can be directed to form a selected combination with the first fibrous material to provide a first superabsorbent-containing stratum. A second fibrous stratum (32) of fibrous material can be deposited to overlie the first fibrous stratum (26), and the second fibrous stratum (32) can have a second stratum thickness (34). A second superabsorbent material (36) can be directed to form a selected combination with the second fibrous material to provide a second superabsorbent-containing stratum.

  • Patent number: 6248097
    Abstract: An absorbent article (10) which includes a backsheet layer (30) having a pair of laterally opposed and longitudinally extending side margins (20). Each side margin has an outwardly concave, terminal side edge contour 15 located at appointed leg opening regions (17) in an intermediate portion (16) of the side margin. Each concave side edge contour (15) has a selected longitudinal extent along a length dimension (26) of the article (10). A liquid permeable topsheet layer (28) is connected in a superposed facing relation to the backsheet layer (30), and an absorbent body (32) is sandwiched between the topsheet layer (28) and the backsheet layer (30). A separately provided gusset-flap composite member (19) is connected to at least one of the backsheet and topsheet layers along each of the leg opening regions (17). The gusset-flap member (19) provides a leg gusset section (142) and a containment flap section (144), and is distinctively configured to provide improved leakage resistance, fit and comfort.

  • Patent number: 6235137
    Abstract: A distinctive method and apparatus for forming an article includes a moving of at least one first strand of material, such as strand (22), along an appointed machine-direction (34). The at least one first strand of material is attached to a base layer of material (42) to provide a substrate composite (40), and a laminate layer (44) can be placed adjacent the at least one first strand of material to provide a laminate composite web (48). In a particular aspect, at least one second strand of material, such as strand (56), can be moved along its appointed machine-direction, and the at least one second strand of material can be attached to the base layer (42). In another aspect, an appointed portion of the base layer (42) can be folded to substantially enclose the at least one second strand (56) with the base layer material.

  • Patent number: 6202259
    Abstract: A method and apparatus for depositing particulate material (30, 36) in an airlaid fibrous web (94) includes a moving of a forming surface (22) through a forming chamber (24), and a laying of a fibrous material (96) onto the forming surface to form the fibrous web. The particulate material is delivered into the forming chamber with an arcuate curved nozzle (86) which is positioned within the forming chamber at a location spaced from the forming surface.
