Abstract

A laminate material web has two webs of nonwoven fabric that lie on the outside, and film strips of an elastic film disposed between them, in sections, whereby the nonwoven fabric webs are connected with one another in the regions between the film strips. The film strips are connected with the inner surfaces of the nonwoven fabric webs only at the two longitudinal edges, in each instance, both on the top and on the bottom, and the nonwoven fabric webs have weakenings running in the web direction, in the regions that cover the film strips. A method for the production of a laminate material web is also described.
