摘要 |
Fibrous material layer intended to be incorporated in an absorbent article. The layer ( 5 ) comprises at least two webs of tow fibers arranged on top of each other, which are bonded to each other into a laminate by means of a bonding pattern, and where one is corrugated and the other web is substantially smooth, wherein the corrugated web exhibits a more open structure in comparison to the smooth web. A method of manufacturing the layer ( 5 ) in question, in which method at least two separate webs ( 15 a, b) of opened and into a layer spread-out tow are fed into a bonding station ( 20 ), which webs exhibit different web tensions and/or web speeds, and that the webs ( 15 a, b) with maintained relative difference in web tension and/or web speed are bonded together in said bonding pattern ( 10 ) into a laminate. |
