Publication number: 20090326503Abstract: A method for producing pant-type absorbent articles, each article including a chassis structure having at least one elastic panel and an integrated absorbent core component, the method including a continuous pant-forming process including forming the chassis structure and incorporating the absorbent core component into the chassis structure. The at least one elastic panel is formed by a) separately producing a two-layer laminate having a first non-elastic fibrous nonwoven web and an elastic film, b) activating the two-layer laminate by incremental stretching in at least one activation direction to render the two-layer laminate (elastically stretchable, c) stretching the activated two-layer laminate by 35-200% in the activation direction, d) introducing the two-layer laminate in the pant-forming process, and e) laminating the elastic film of the stretched two-layer laminate to an elastic or nonwoven chassis component. An absorbent pant-type article produced in accordance with the method.Type: ApplicationFiled: May 11, 2007Publication date: December 31, 2009Applicant: SCA HYGIENE PRODUCTS ABInventors: Elisabeth Lakso, Hans Een, Jan Wästlund-Karlsson
