Abstract:
A method for producing a web of a laminate material for retaining faeces including laminating first and second webs to form an intermediate laminate web, providing transversal slits in the intermediate laminate web and expanding the intermediate laminate web such that the slits are opened to openings. An expanded intermediate laminate web is formed by the expansion. The expanded web is laminated to a third web in order to fix the expanded web in an expanded state, whereby the laminate material web is formed. Also, a method of producing an absorbent article including producing the laminate material web according to the method above.
