An absorbent article has a front side, a back side, a longitudinal axis, a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core between the topsheet and the backsheet. The absorbent core includes a first type of channels, wherein the top side and the bottom side of the core wrap are bonded to another, and a second type of channels, wherein the top side and the bottom side of the core wrap are not bonded or are less bonded to one another in this second type of channels than in the first type of channels. The absorbent material may also include cellulose and superabsorbent particles.

Absorbent core, articles comprising said core, and methods of making

An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

Apparatus and method for forming an absorbent pad

An apparatus for forming an absorbent pad for an absorbent sanitary article having a zone free of absorbent material to define a channel of the pad includes a forming drum, a first feed system for feeding a first web, a second feed system for feeding a second web, a spreader for spreading the absorbent material on the drum; a joining system for joining the first and second webs to define the channels. A first dispenser forms on the first web a layer of first adhesive substance according to a spreading pattern having zones free of the first adhesive substance corresponding to the channels. A second dispenser dispenses a second adhesive substance, whose adhesive force is greater than an adhesive force of the first adhesive substance, on the second web according to a pattern having a layer placed at a zone free of the first adhesive substance.

ABSORBENT ARTICLES AND METHODS OF MAKING

An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet, and an acquisition distribution system positioned between said topsheet and said absorbent core, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels substantially free of said absorbent material, wherein said channels have a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channels is from 10% to 95% of the length of said absorbent core and wherein said channels each follow a substantially continuous path such as from a first end of a channel to a second end of the same channel wherein the acquisition distribution system is multi-layered and comprises at least one spunbond layer and at least one meltblown layer, and wherein said acquisition distribution system is positioned between said absorbent core and said topsheet such that said spunbond and/or meltblown layers are in direct contact with said absorbent core and said topsheet.

Method and Apparatus for Making an Absorbent Structure Comprising Channels

The present invention relates to an apparatus and method for making an absorbent structure for an absorbent article, comprising a supporting sheet and thereon an absorbent layer, the absorbent layer comprising an absorbent material. According to the present invention a first moving endless surface is provided which has one or more substantially longitudinally extending first mating strips, and at least one further auxiliary moving endless surface is provided which acts against the first mating strips.
