    摘要： An in-line formed, non-laminated web is suitable for use as a composite fluid distribution and fluid retention layer in a disposable absorbent article. The web can be formed by selective deposition of airlaid materials including absorbents, such as pulp and superabsorbents, together with binder fibers. The web so constructed will have a plurality of intermingled lower basis weight areas and higher basis weight areas coexisting and distributed in at least a central region of the web, the alternations crossing the X axis or Y axis, or both, of the web, with the higher basis weight areas being a greater thickness in the Z-direction than the lower basis weight areas. The web so constructed will further have no discrete material boundaries between the lower basis weight stripes and the higher basis weight stripes. Further the necessity of later processing on the web to achieve a ridged structure is removed and the fibers will remain whole and undisturbed. The selective vacuum manipulation in conjunction with multiple fiber deposition heads, and appropriate timing of fiber addition therefrom, will yield a variety of useful composite webs having multiple layers thereby forming an economical single web which may be easily incorporated into an absorbent garment or article.

    摘要： Methods and systems for making an absorbent pad for use in an absorbent article utilize a forming device for forming material into an absorbent core, a supply device for supplying a containment layer against the first surface of the absorbent core and spray apparatus for spraying fibers of molten resin onto the second surface of the absorbent core. The fibers form a stabilization layer on the absorbent core that increases the integrity of the absorbent core. The spray apparatus includes a nozzle having a resin aperture for exhausting resin therefrom and multiple gas apertures for exhausting gas therefrom to provide a random pattern to the fibers of molten resin as the fibers are sprayed onto the second surface. Resin can also be sprayed onto first and second portions of the containment layer extending outwardly from edges of the absorbent core so the containment layer and the stabilization layer encompass the absorbent core. In another embodiment, a second containment layer can be placed on the second surface of the absorbent core and first and second stabilization layers can be spaced outwardly therefrom and deposited on the absorbent core.
