The present invention relates to an absorbent structure suitable in, or being an adult or infant diaper or feminine hygiene article, comprising a water-absorbing material comprising water-absorbing particles that comprise a film coating, comprising an elastic film-forming polymer and a coalescing agent.The invention also relates to an absorbent structure comprising a water absorbent material obtainable by a process of:a) spray-coating water-absorbing polymeric particles with an elastic film-forming polymer in a fluidized bed reactor at a temperature in the range from 0° C. to 150° C. andb) heat-treatment of the coated polymeric particles at a temperature above 50° C., wherein in step a) and / or b) a coalescing agent is added.

Methods of and apparatus for bonding and / or embossing of materials, especially materials used in the manufacture of hygienic articles, including, but not limited, to absorbent articles such as feminine hygiene articles, disposable diapers, incontinence devices, wipes, and the like.

A feminine hygiene article such as pantiliner having a topsheet and a backsheet. The article further includes a printed pattern and an embossed pattern. The embossed pattern has at least one embossed decorative element and the printed pattern has a printed decorative element which is substantially similar to the embossed decorative element.

The present invention relates to a method and apparatus for forming a composite structure, preferably for use in an absorbent structure used within the personal hygiene industry, such as for instance feminine hygiene garments, baby diapers and pants and adult incontinence garments. The present invention preferably provides a method and apparatus for depositing and positioning particulate materials in a desired pattern onto a moving carrier layer. The method allows accurate forming of a pattern of particulate material clusters at high production speed having improved attachment properties, with reduced raw material usage and relative low cost. The present invention foresees in the need for improved thin, flexible, lightweight absorbent structure having optimal absorption, distribution and retention.

A new machine control method and system for registering pre-produced webs into a converting line producing disposable absorbent articles such as diapers, pull-ups, feminine hygiene articles or a component thereof. The pre-produced webs can include a multiplicity of pre-produced objects spaced on the web at a pitch interval in the web direction. The pre-produced web being manipulated in order for the pre-produced object of the web to be registered in relation to a target position. The present invention includes five embodiments, where the first embodiment is expressed as a generic claim. The first embodiment includes a closed-loop feedback registration system; the second and third embodiments, in addition, include an open-loop feedforward control system; the fourth and fifth embodiments, in addition, include an automatic phasing system. In addition, the third embodiment uses a machine vision system to recognize any element of a complex pre-produced object (e.g., colorful graphics).

The present invention relates to an absorbent structure, preferably for use in absorbent articles as used in the personal hygiene industry such as feminine hygiene garments, baby diapers and pants or adult incontinence garments. The present invention also relates to an absorbent article comprising such absorbent structure and to a method of manufacturing the absorbent structure. The absorbent structures comprise a carrier layer, an auxiliary layer and an absorbent material there between wherein substantially permanent primary attachments and substantially temporary secondary attachments join the carrier layer and auxiliary layer at least partially together, whereby the substantially temporary secondary attachments are loosened as a result of exposing the absorbent structure to a liquid whereas the substantially permanent primary attachments remain substantially intact. The present invention foresees in the need for improved flexible, thin, lightweight absorbent structures for an absorbent article which overcomes the absorbency problems of the prior art during absorption, distribution and retention of liquids with optimal fit.

A tampon for feminine hygiene that has an insertion end, a withdrawal end, a central portion between the insertion end and the withdrawal end, a length, a longitudinal axis, a radial axis, and an outer surface. The tampon is made of compressed fibrous material. The outer surface of the insertion end has a plurality of longitudinal grooves which are offset from the plurality of longitudinal grooves located in the withdrawal end.
