Zusammenfassung:	The present invention relates to an apparatus for forming air-laid absorbent cores, comprising a first and second mat-forming wheel (1,2). According to the invention means are provided for applying a first and second web of casing material (9,10) onto the peripheral surface of the first and second mat-forming wheel (1,2), respectively, for providing a third web of casing material (11) into the nip between the first and second mat-forming wheel, for applying an adhesive coating on both sides of the third web, the mat- forming wheels (1,2) being so positioned that the formed core elements on the respective first and second mat-forming wheels will abut the third web (11) when passing the nip between the first and second mat-forming wheel, and for pressing together the portions of the three webs located outside the contour of the core element, containing the first and second core element, whereby the air-laid core elements will encapsulated in casing material. The invention also relates to a method for forming air-laid absorbent cores.
