A method and an apparatus for pre-fastening disposable absorbent articles having a slot-and-tab fastening system during manufacturing of the pre-fastened disposable articles, such as diapers, pull-on diapers, training pants, adults incontinence pads and the like.

The present invention relates to a visual indicating device and an article for controlling odors, in particular foot, garbage, basement, cooking, pet, tobacco, feces and urine odors. The article comprises a visual indicating agent that is color sensitive to the odor, and optionally, an odor absorbing agent. The visual indicating agent changes color when the article has been exposed to a sufficient amount of odor to saturate the article. The indicating agent may be applied in differing concentrations to two or more zones so as to indicate to a user of the article how much of the odor absorbing capacity has been used, or conversely, how much of the odor absorbing capacity remains. Suitable visual indicating agents that change color in response to odors are also described. The article for controlling odors may be a disposable odor absorbing sheet, air freshening product, diaper, undergarment pad, face mask, air filtration device, sanitary napkin, tampon, panty shield or incontinence pad.

The present invention is directed to nonwoven webs and articles comprising nanofibers. The nanofibers are made from a polymer having a glass transition temperature above about 25 C. The nanofibers, having a diameter of less than 1 micron, may comprise a significant number of the fibers in one layer of the web contained by the article. Preferably, the nanofibers are produced in a melt film fibrillation process. Articles include diapers, training pants, adult incontinence pads, catamenials products such as feminine care pads and pantiliners, tampons, personal cleansing articles, personal care articles, and personal care wipes including baby wipes, facial wipes, and feminine wipes.

The present invention is directed to hygiene articles comprising nanofibers. The hygiene articles include diapers, training pants, adult incontinence pads, catamenials products such as feminine care pads and pantiliners, tampons, personal cleansing articles, personal care articles, and personal care wipes including baby wipes, facial wipes, body wipes, and feminine wipes. The nanofiber webs can be used as a barrier, wipe, absorbent material, and other uses. Particularly, the nanofiber web is used in a diaper as a barrier-on-core, outercover, and/or leg cuff. It may also be used as a wipe for reducing the gradient of liquid, controlled delivery of materials, and other uses. The nanofibers, having a diameter of less than 1 micron, must comprise a significant number of the fibers in one layer of the web contained by the hygiene article. The nanofibers are produced from a melt film fibrillation process. The process generally includes the steps of providing a polymeric melt, utilizing a central fluid stream to form an elongated hollow polymeric film tube, and using this and/or other fluid streams to form multiple nanofibers from the hollow tube.

Preferably an acquisition layer (40) is provided between the topsheet (24) and the absorbent core (28). The acquisition layer preferably extends into the embossing (50), while a resilient absorbent member (30) is preferably provided between the absorbent core (28) and the acquisition layer (40) in the form of stripes arranged longitudinally spaced along the upper longitudinal sides of the channel (50) formed by the embossing.

A disposable incontinence pad with a longitudinal direction and a transverse direction and intended for men, includes an absorbent part with an upper liquid-permeable surface layer, a lower backing layer, and an absorbent body arranged between the liquid-permeable surface layer and the backing layer. The disposable incontinence pad also has a front end portion and a fastening system for fixing the incontinence pad to a pair of underpants, fixing pants or the like. The fastening system includes at least one fixing tongue extending in the longitudinal direction of the incontinence pad from the front end portion.

An absorbent product such as a panty liner, incontinence pad, sanitary towel or the like comprising a top layer consisting of a first material layer and a second material layer, the first material layer being attached directly to the second material layer. The first material layer has a first part and a second part, where the first part and/or the second part contains openings, and where the first part is folded over the second part along a fold line, the first material layer being attached directly to the second material layer adjacent to at least one line extending in the longitudinal direction in an inner joining zone. A method for the manufacture of an absorbent product of this kind.

The present invention is directed to articles comprising nanofibers. The nanofibers, having a diameter of less than 1 micron, may comprise a significant number of the fibers in one layer of the web contained by the article. Preferably, the nanofibers are produced in a melt film fibrillation process. The articles include diapers, training pants, adult incontinence pads, catamenials products such as feminine care pads and pantiliners, tampons, personal cleansing articles, personal care articles, and personal care wipes including baby wipes, facial wipes, and feminine wipes.

A packing wrap (1) for enclosing an individual packed absorbent article (2), such as a sanitary towel, a panty liner or an incontinence pad, including a first material piece (3) arranged over the first surface of the absorbent article (2) and a second material piece (4) arranged over the second surface of the absorbent article (2), an opening location (5) having a longitudinal extent, and a region capable of tactile detection of the opening location, the region (12) being arranged adjacent to the opening location (5).

Absorbent sanitary articles (2), such as nappies or incontinence pads with an elongated central body (2a) and at least one pair of closure tabs (5), are manufactured on a machine (1) by which the tabs (5) are directed in pairs from a feed unit (13) onto a transport line (6) carrying the articles (2) toward a sealing station. The feed unit (13) operates by making skew cross-cuts (16) in a continuous strip (15) of material, so as to generate a succession of tab elements (5) appearing trapezoidal in outline; the tab elements (5) are then distanced one from another in alternation along a direction (D3) transverse to their feed direction (D2) through the machine, so as to obtain two single columns (23) which are taken up by a roller (27) and aligned one with another so that the single tab elements (5) are ordered into a succession of transversely aligned pairs. The alignment roller (27) rotates tangentially to the transport line (6) and is timed to place one pair of tab elements (5) on each advancing article (2).
