Abstract

A method is described in which at least a first card web (VI), consisting at least partially of absorbent fibers, is combined with a supporting non-woven fabric (NT1) and with an acquisition and distribution layer (NT2). Particles (P) of at least one super-absorbent polymer are inserted into the composite strip material formed in this way.
