This invention provides a process and apparatus (38) for the manufacture of disposable absorbent cores from a continuous web (40), wherein a plurality of first and second core elements (40a, 40b) are cut from the same continuous web (40). The object of the invention is achieved by rotating each of first and second core elements (40a, 40b) about axes perpendicular to the plane of the core element and subsequently combining a first core element (40a) and a second core element (40b) in proximal relationship to form the absorbent core. Preferably each of the first and second core elements (40a, 40b) are rotated through 90~ in mutually counter-rotating directions.
La présente invention concerne un procédé et un appareil (38) destiné à la fabrication d'âmes absorbantes jetables à partir d'une bande continue (40). En l'occurrence, on découpe dans la même bande continue (40) une pluralité de premiers et de seconds éléments d'âme (40a, 40b). Plus particulièrement, on fait tourner chacun des premiers et seconds éléments d'âme (40a, 40b) autour d'axes perpendiculaires au plan de l'élément d'âme puis on combine un premier élément d'âme (40a) à un second élément d'âme en relation proximale de façon à former l'âme absorbante. De préférence, chacun des premiers et seconds éléments d'âme (40a, 40b) subissent une rotation de 90· en sens inverse l'un par rapport à l'autre.
