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. (FIG. 1)
