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.
Abstract:
The present invention relates to a method of applying absorbent gelling material (AGM) granules by indirect printing onto an carrier layer for use in an absorbent article, particularly diaper for babies or adults, training pants, pull-up diapers (diaper pants), sanitary napkins, panty liners or the like. These articles typically comprise the carrier layer with the AGM particles together with further layers, making up the complete article.

Abstract:
The present invention is method for forming a sandwich structure having a pattern of particulate material enveloped between a carrier material and a cover material. The method allows accurate forming of pre-determined pattern at high production speed. Such a method is particularly useful in the manufacture of disposable absorbent articles, such as baby diapers.
Abstract:
A method for making a disposable absorbent core comprises depositing absorbent particulate polymer material from a plurality of reservoirs in a printing roll onto a substrate disposed on a grid of a support which includes a plurality of cross bars extending substantially parallel to and spaced from one another so as to form channels extending between the plurality of cross bars. The plurality of reservoirs in the first peripheral surface are arranged in an array comprising rows extending substantially parallel to and spaced from one another. The support and printing roll are arranged such that the plurality of cross bars are substantially parallel to the rows of the plurality of reservoirs and the absorbent particulate polymer material is deposited on the substrate in a pattern such that the absorbent particulate polymer material collects in rows on the first substrate formed between the first plurality of cross bars. A thermoplastic adhesive material is deposited on the absorbent particulate polymer material and the substrate to cover the absorbent particulate polymer material on the substrate and form an absorbent layer. A disposable absorbent article and apparatus for making an absorbent article are also disclosed.
Abstract:
A disposable absorbent article comprising a chassis including a topsheet and a backsheet, a substantially cellulose free absorbent core located between the topsheet and the backsheet and having a wearer facing side oriented toward a wearer when the article is being worn and an opposed garment facing side, and a liquid acquisition system disposed between the liquid permeable topsheet and the wearer facing side of the absorbent core comprising chemically cross-linked cellulosic fibers.
Abstract:
A disposable absorbent article includes an absorbent core that is substantially cellulose free and a chassis that includes a topsheet and a backsheet, with the absorbent core located between the topsheet and the backsheet. The chassis may include a pair of side panels joined with the chassis, the side panels extending laterally outwardly beyond the longitudinal edges, each side panel having at least one zone extensible in a direction having a vector component in the lateral direction.
