    摘要: 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).

    摘要: 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.
