Method and apparatus for making disposable absorbent article with absorbent particulate polymer material and article made therewith
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. A disposable absorbent article and apparatus for making an absorbent article are also disclosed.
NIPPLE ABSORBENT ELEMENT
Nipple absorbent element, including a body having a substantially flat development and having an inner surface configured to be in contact with the nipple and an outer surface; wherein at least said inner surface is made of soft, yieldable and absorbent material to retain liquids exiting the nipple; and wherein the outer surface has a fluorescent graphic representation corresponding to a respective condition of the breast for feeding.
TACKIFIER-FREE HOT MELT ADHESIVE COMPOSITIONS SUITABLE FOR USE IN A DISPOSABLE HYGIENE ARTICLE
A hot melt adhesive composition comprises a polypropylene homopolymer having a DSC melting point of less than 100° C.; a butene-based copolymer; and a plasticizer. The butene-based copolymer may comprise a butene-rich amorphous poly-alpha olefin, such as a butene-propylene copolymer, or a semi-crystalline copolymer, such as a butene-ethylene copolymer. The hot melt adhesive is especially useful for bonding substrates which swell or elongate significantly in use. Such uses include adhering superabsorbent polymers to a substrate or adhering together two substrates at least one of which having superabsorbent polymers, such as the top and bottom layer of an absorbent core of a disposable hygiene article, such as a diaper, feminine sanitary napkin, and adult incontinence pad. The hot melt adhesive composition, which does not contain a tackifier, demonstrates suitable elongation at break and stress at yield, with a sufficiently low viscosity, to stabilize an absorbent core having superabsorbent polymers.

Process for preparing an absorbent article
The present invention is directed to a novel process for preparing an absorbent article, wherein the process comprises providing a first sheet layer (2); conforming said first layer on a first roll C2, whereby longitudinal corrugations are formed on the layer; conforming said corrugated layer (2) on a second roll C3, whereby a pattern of pockets (4, 4a) is obtained; providing a pre-metered amount of SAP particulate material (6); providing a second sheet layer (7) material and affixing it for sandwiching with the first sheet layer; and finishing the absorbent article.
Process for preparing an absorbent article
The present invention is directed to a novel process for manufacturing an absorbent article comprising the steps of: providing a first sheet layer (2); providing an array of pockets (4, 4a) into said first sheet layer; providing a pre-metered amount of SAP particulate material (6); said pre-metered amount of SAP material being delivered from a rotating delivering drum (101, 111), said drum having apertures (103a, 103b, 103c, 103d, 113a, 113b, 113c) on its periphery corresponding to the array of pockets (4, 4a), said pre-metered amount of SAP material being delivered from the inner part of said drum (101, 111) through said apertures (103a, 103b, 103c, 103d, 113a, 113b, 113c); providing a second sheet layer (7) material and affixing it for sandwiching with the first sheet layer; finishing the absorbent article.
Tackifier-free hot melt adhesive compositions suitable for use in a disposable hygiene article
A hot melt adhesive composition comprises a polypropylene homopolymer having a DSC melting point of less than 100 C.; a butene-based copolymer; and a plasticizer.

Absorbent article and process for making it
The present invention is directed to a liquid-absorbing article comprising: a first sheet layer presenting an array of absorbent receiving pockets; masses of superabsorbent material, which masses are placed in said absorbent receiving pockets; a second sheet layer placed on top of the first layer; bonding beads placed between the respective pockets.
WOUND DRESSING
A wound dressing (10) having a periphery having an outline. The wound dressing comprises an absorbent pad having an outline. The outline of the periphery and the outline of the absorbent pad have the same shape. The shape comprising two lobes, the boundary between the two lobes defining a flex line, and at least one lobe comprising a least one notch.
