Absorbent product in the form of cowards and Method for the manufacture of absorbent product in the form of cowards

摘要

1. A method of manufacturing absorbent articles in the form of pants, where each product (21) contains a basic structure containing at least one elastic section and an integrated absorbent core component (32), the method comprising a continuous process of forming pants, comprising the step of forming the base structure and the step of embedding the absorbent component (32) of the core in the base structure, characterized in that at least one elastic section is made by performing the following steps! a) separately produce a two-layer layered material (8) containing the first inelastic fibrous non-woven fabric (1) and an elastic film (6),! b) activate the bilayer laminate (8) by incrementally pulling in at least one direction to make the bilayer laminate (8) elastically extensible,! c) stretch the activated bilayer laminate (8) by 35-200% in at least one direction,! d) introduce a two-layer layered material (24, 25) into the process of forming cowards, and! e) laminate the elastic film (6) of the elongated bilayer laminate (24, 25) over a non-woven base component (39, 40, 23, 54). ! 2. The method according to claim 1, in which the non-woven base component (39, 40, 23, 54) is an inelastic component. ! 3. The method according to claim 1 or 2, in which the component (32) of the core is formed separately from the process of forming cowards and introduced into the process of forming cowards before or after lamination of the elastic film (6) along the non-woven base component (39, 40, 23, 54 ) ! 4. The method according to claim 1, in which the process of forming cowards comprises laminating the sides of the elastic film of the first web (24) activated in
