  • Patent number: 6656311
    Abstract: A method and apparatus (20) for making an absorbent article can include a delivering of a first contoured web-strip (30a) from a first production supply (38) of contoured web-strip material, with the first contoured web-strip (30a) presenting a primary production sequence of side edge contours during its delivery. At least a second contoured web-strip (30b) can be delivered from a second production supply (40) of the contoured web-strip material, with the second contoured web-strip (30b) also presenting the primary production sequence of side edge contours during its delivery. In a particular aspect, the first and second contoured web-strips (30a and 30b) have been produced from a web (22) of absorbent material which has been divided to provided at least two web-strips (30) having a substantially nested configuration.
    Type: Grant

  • 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: 5762844
    Abstract: A distinctive method and apparatus (20) for forming a composite fibrous web (22) includes a web supply (24, 25), which provides at least two appointed fiber layer sections (26, 28) of desired fiber material. Each of the layer sections (26, 28) has a selected composition. A fiberizer (30) disintegrates each of the fiber layer sections (26, 28) into individual, laterally adjacent fiber streams (32, 33) while substantially maintaining a lateral separation of the fiber streams while the fiber streams (32, 33) are moving through the fiberizer (30). A directing channel (34) delivers the fiber streams (32, 33) from the fiberizer (30) to a forming chamber (40). The forming chamber (40) is configured to substantially maintain the separation of the fiber streams.
