摘要:
A tampon for feminine hygiene, having an insertion end, a recovery end, a recovery tape, and a longitudinal axis. The tampon is made of compressed fibrous material and has an outer surface that is at least partially provided with spirally shaped, pressed longitudinal grooves. The grooves define spirally shaped longitudinal ribs. Also disclosed is a method for producing the tampon.

An absorbent-body manufacturing apparatus manufactures an absorbent body by depositing absorbent-body material in a plurality of recess sections spaced at an arrangement pitch on an outer circumferential face of a drum. The apparatus has a driving source that drives the drum in synchronization with another apparatus based on a synchronization signal. First and second signal-generating sections repeatedly generate first and second rotational-angle signals based on a rotation of the drum with a rotational angle of the drum as a unit, the rotational angle of the drum corresponding to first and second pitches, respectively. Depending on whether the arrangement pitch is set to the first or second pitch, a controller controls rotational driving operation of the driving source based on the first or second rotational-angle signal and on the synchronization signal.
摘要:
Apparatus and methods are provided to allow for creation of a configured laminate of a non-woven material, to which a character strip is applied, the character strip exposed by either heat severing and removal of overlying materials, or intermittent application of overlying materials to leave the desired portions of the character strip exposed. A simultaneously formed core insert is applied to a preformed chassis web.

An apparatus for compressing a material includes a central longitudinal axis, a plurality of levers each having a tool carrier and defining a lever longitudinal axis, and a plurality of jaws each attached to a lever at a tool carrier to form a lever/jaw combination, wherein each jaw has a compression surface having an area. The apparatus also includes a compressing mechanism configured to move each lever in a non-linear motion such that the area of a compression surface exposed to the material decreases with the inward movement of that compression surface, wherein each lever/jaw combination includes a biasing mechanism configured such that adjacent jaws contact each other. The plane of each compression surface can be predominantly tangential to the apparatus central longitudinal axis. Each biasing mechanism can be configured to bias its jaw along the lever longitudinal axis toward an adjacent jaw.

Methods for forming discrete deformations in web materials are disclosed. In some embodiments, the method involves feeding a web into an apparatus having nips that are formed between intermeshing rolls. The apparatus may be in the form of nested or other arrangements of multiple rolls, in which the web is maintained in substantial contact with at least one of the rolls throughout the process, and at least two of the rolls define two or more nips thereon with other rolls. In some embodiments, rolls can be used to expose a different side of the web for a subsequent deformation step. In these or other embodiments, the rolls can be used to transfer the web between rolls in such a manner that it may offset the rolls and/or web so that subsequent deformations are formed at a different cross-machine direction location than prior deformations.
摘要:
An absorbent structure comprising a planar substrate, an auxiliary glue applied on the substrate, an absorbent material comprising from 80% to 100% by weight of superabsorbent particles deposited on the substrate on an absorbent material deposition area comprising a pattern of absorbent material land areas separated by absorbent material-free junction areas, wherein the deposition area can be notionally divided in eight deposition zones of equal length along the longitudinal direction. A fibrous thermoplastic adhesive layer immobilizes at least some of the absorbent material. The absorbent material is profiled along the longitudinal direction so that at least one of the eight deposition zones is a zone of lower absorbent material amount and the auxiliary glue is absent, or present at a level of at least 50% by weight lower than the average amount of auxiliary glue in at least one of these zones of lower absorbent material amount.
摘要:
An article including: an absorbent body including two liquid-permeable non-woven fabric sheets bonded together at bonded portions in a predetermined pattern, and a plurality of granular particles placed therebetween separately in each of a plurality of placement areas partitioned from one another in the predetermined pattern; and a non-liquid-permeable back sheet placed on a non-skin-contact surface of the absorbent body, wherein: a liquid-permeable sheet is placed so as to cover an entire surface of the non-woven fabric sheet on a skin-contact surface side; and an easily-breakable portion capable of being broken when the granular particles absorb a bodily fluid to swell is formed in placement areas on at least one non-woven fabric sheet.
摘要:
The present invention relates to a method for fabricating absorbent article having multiple layers, and deformed zones of targeted performance, and colored regions, the method comprising the steps of forming discrete features on at least one layer, printing colored regions on at least one layer, integrating multiple layers to form an absorbent assembly, and cutting the absorbent assembly into individual absorbent articles, wherein the steps are carried out continuously.
摘要:
The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatus comprises a bonding roll comprising a base surface and plurality of nubs extending from the base surface, each of the plurality of nubs comprising: a sidewall; a bonding surface; and a shoulder connecting the sidewall to the bonding surface. The shoulder comprises a single chamfer or a radius to, inter alia, reduce tearing of the substrates.
摘要:
An elastic laminate has a coextruded film having an outer film layer formed of an elastic and sticky styrene-block copolymer and an inner film layer of lesser elasticity than the outer layer, an outer fleece or nonwoven web or overlay, an outer adhesive layer between the outer fleece web and the outer film layer adhering the outer fleece web to the outer film layer, an inner fleece or nonwoven web or overlay, and an inner adhesive layer between the inner fleece web and the inner film layer adhering the inner fleece web to the inner film layer. The inner adhesive layer forming between the inner fleece web and the inner film layer a bond that is weaker than a bond formed by the outer adhesive layer between the outer fleece web and the outer film layer such that on stretching the inner fleece layer separates locally from the inner film layer.
