Claim Text:
1. A method for producing a web of a laminate material for retaining faeces for use in an absorbent article comprising the steps of: providing a first web of a first material for contacting the skin of a user of said absorbent article; providing a second web of a second material, said second material being a volume-forming material; laminating said first web and said second web so as to form an intermediate laminate web, said intermediate laminate web having a longitudinal direction, a transverse direction and a thickness direction; providing a multitude of transversal slits in said intermediate laminate web, each slit extending through said first material and said second material of said intermediate laminate web in said thickness direction; expanding said intermediate laminate web in said longitudinal direction such that said slits are opened to openings for retaining faeces, whereby said expansion provides an expanded intermediate laminate web in the form of a reticulated structure, providing a third web of a third material for fixing said expanded intermediate laminate web such that it is maintained in an expanded state, and laminating said second material of said expanded intermediate laminate web and said third web, whereby said expanded intermediate laminate web is fixed in position in relation to said third web and is fixed in an expanded state, and whereby said laminate material web is formed, wherein said first material of said produced laminate material web comprises two longitudinal first material edges and said second material of said produced laminate material web comprises two longitudinal second material edges, wherein said third material of said produced laminate material web extends outside said longitudinal first material edges and said longitudinal second material edges such that said third material of said laminate material web comprises two longitudinal portions of non-laminated third material, and wherein said method for producing said laminate material web further comprises the step of: folding and bonding said non-laminated third material of said produced laminate material web to said first material so as to cover at least said longitudinal first material edges and said longitudinal second material edges of said laminate material web by said non-laminated third material.
