Abstract
A method and an apparatus for forming air-laid fibrous absorbent cores comprises a first supply of air-entrained fibrous material and a first air-laying element connected with the first supply of air-entrained fibrous material and having a movable first perforated forming element for forming a first air-laid component of the absorbent core. Further, a supply of air-entrained fibrous material and discrete particles of absorbent material and a second air-laying element connected with the supply of air-entrained fibrous material and discrete particles is provided. The second air-laying element has a movable second perforated forming element for forming a second air-laid component of the absorbent core comprising a mixture of dispersed fibrous material and discrete particles and the second air-laying element is positioned with respect to the first air-laying element such as to transfer a formed second component from the second forming element onto a formed first component on the first forming element.
