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.

La présente invention concerne un procédé de formation d'éléments en forme tels que des noyaux absorbants en forme destinés à des articles absorbants jetables, qui consiste à prendre une bande de matière relativement large à partir de laquelle des éléments sont découpés. Cette bande de matière est entaillée longitudinalement de façon à former une pluralité de bandes subdivisées, chacune d'elles possédant des éléments en forme agencés en série. Les éléments en forme contigus à d'autres éléments en forme des bandes subdivisées sont emboîtés entre eux, c'est à dire qu'une ligne longitudinale de cette bande s'étend à travers les éléments de bandes subdivisées contiguës. Une formation efficace est facilitée par le recueil des parties marginales de la bande de matière et par un recyclage au moins partiel des parties recueillies pour la formation de la bande large.
