  • Patent number: 6913718
    Abstract: A method for formation of shaped components such as shaped absorbent cores, for disposable absorbent articles, contemplates that a relatively wide web of material be provided from which the components are cut. The web of material is longitudinally slit to form a plurality of subdivided webs each having shaped components arranged in serial relationship. The shaped components of adjacent ones of the subdivided webs are nested with each other, that is, a line extending longitudinally of the web extends through the components of adjacent subdivided webs. Efficient formation is facilitated by collecting the marginal portions of the web of material, and at least partially recycling the collected portions for formation of the wide web.
