1. An absorbent body for an absorbent article, said absorbent body comprising:
- at least two layers of absorbent material,a layer of superabsorbent particles laid upon each of said at least two layers, said particle layers including patterns of superabsorbent particles and through-penetrating openings between said superabsorbent particles, said through-penetrating openings being defined where there are substantially no superabsorbent particles,one of said layers of absorbent material being secured above another of said layers of absorbent material such that said through-penetrating openings of said particle layer of said one layer of absorbent material are horizontally displaced in relation to said through-penetrating openings of said particle layer of said another layer of absorbent material such that said openings defined where there are substantially no superabsorbent particles in said one layer are not vertically aligned with said openings defined where there are substantially no superabsorbent particles in said another layer.

Abstract
An absorbent body and an apparatus for manufacturing an absorbant body having at least two layers of absorbent material, upon each of which a layer of superabsorbent particles has been laid. The particle layers include patterns of through-penetrating openings and one of the particle layers is horizontally displaced in relation to another of the particle layers.

24. An apparatus for manufacturing absorbent bodies for absorbent articles such as diapers, incontinence guards or sanitary napkins, the apparatus comprising:
-
means for passing a first fibre body past particle applicator means, means for delivering particles in a first predefined pattern containing particles and through-penetrating openings onto said first fibre body, said through-penetrating openings being defined by a general lack of particles, means for placing a second fibre body on top of the first fibre body after having applied the layer of particles to said first fibre body, means for applying to the second fibre body a layer of particles in a second predefined pattern containing particles and through-penetrating openings, said through-penetrating openings being defined by a general lack of particles, said second predefined pattern of particles and through-openings being displaced in relation to the first predefined pattern of particles and through-openings applied to the first fibre body such that the through-openings of the second fibre body are displaced and therefore not vertically aligned in relation to the through-openings of the first fibre body disposed therebelow, and means for compressing the thus obtained composite absorbent body. - View Dependent Claims (25)

26. An absorbent article, comprising:
-
an absorbent body having at least two layers of absorbent material, upon each of which a layer of superabsorbent particles has been laid, said particle layers including patterns of through-penetrating openings and one of said particle layers being horizontally displaced in relation to another of said particle layers, wherein said absorbent body is enclosed between a liquid-permeable casing layer and a liquid-impermeable casing layer.
