ABSORBENT ARTICLE
An absorbent article includes an absorbent core. The article has a central longitudinal axis and a central transverse axis extending perpendicular to said longitudinal axis, the absorbent article having a front end edge and a back end edge. The absorbent article has a front portion, a back portion and a crotch portion. The absorbent core includes a coherent area disposed in at least the front portion and the crotch portion. The coherent area is in an absorbent component. The core cover includes a sealing arrangement for joining the upper and lower sides in the form of at least one sealed channel. The sealed channel is free or substantially free from absorbent material. The absorbent component includes oblong high density areas extending in the longitudinal direction at least in the front portion of the absorbent article.
ABSORBENT CORE WITH NONWOVEN WEB(S) COMPRISING SUPERABSORBENT FIBERS
An absorbent core including one or more nonwoven webs with superabsorbent fibers. The superabsorbent fibers may include one or more surfactants. The one or more nonwoven webs have an amount of extractables of less than 20 weight-%, and/or an amount of titratable soluble of less than 20%. The nonwoven webs have a capacity of at least 7 g/g. The absorbent core may be used in an absorbent article.

Absorbent articles and methods of manufacturing the same
An absorbent article includes a chassis having a substantially rectangular shape a first portion, a second portion and a crotch portion extending between the first and second portion, a portion of the chassis being configured to absorb fluids. The absorbent article includes a first securement portion operatively coupled to the first portion of the chassis. The absorbent article includes a second securement portion operatively coupled to the second portion of the chassis and configured to releasably attach to the first securement portion. The chassis is configured to include one of a first chassis length or a second chassis length. When the chassis includes the first length, the chassis includes a first width and the first securement portion includes a second width, and when the chassis includes the second length, the chassis includes the first width and the first securement portion includes a third width, greater than the second width.

PROCESS AND APPARATUS FOR MAKING CHANNELED ABSORBENT ARTICLES
A method for making an absorbent article comprising an absorbent core comprising one or more channels, the method comprising the steps of: i. providing a first endless moving surface comprising a plurality of molds typically in the form of pockets, each mold comprising an insert therein, wherein the molds are in fluid communication with an under-pressure source except for said insert such that a suction zone is formed in areas neighboring said insert; ii. feeding a first nonwoven web to said first endless moving surface and over one or more said molds; iii. depositing an absorbent material, comprising cellulose fibers and/or superabsorbent polymer particles, over at least a portion of said nonwoven web; iv. optionally further selectively removing said absorbent material from areas of the nonwoven web corresponding to said insert; v. applying a second nonwoven web directly or indirectly over the absorbent material, or folding said first nonwoven web, such to sandwich said absorbent material between upper and lower layers of said nonwoven web(s); vi. joining said upper and lower layers together at least in the areas of the nonwoven web(s) corresponding to the insert to form an absorbent core having one or more channels substantially free of absorbent material; vii. optionally joining an acquisition distribution layer to said absorbent core, typically a skin facing surface of said upper layer; viii. optionally laminating said absorbent core and acquisition distribution layer between a liquid pervious topsheet and a liquid impervious backsheet; wherein at least a portion of said insert is porous and is in fluid communication with a positive pressure source such that air is blown out of said insert to form an air cushion or air film around at least an uppermost surface of said insert and in that said absorbent material is thereby forced away from areas of the nonwoven web corresponding to said insert.

Multi-layer material for use in an absorbent article
An absorbent article which can have an improved vertical absorption capability in the depth direction of the absorbent article. The absorbent article can have a topsheet layer, a backsheet layer, and an absorbent system positioned between the topsheet layer and the backsheet layer. The absorbent system can have at least a fluid intake layer and an absorbent core. The fluid intake layer can provide the absorbent article with a raised portion which can improve the vertical absorption capability in the depth direction of the absorbent article.

ABSORBENT ARTICLES HAVING CHANNEL-FORMING AREAS AND WETNESS INDICATOR
An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.
