Abstract
The present invention relates to a method for mutually bonding at least two moving continuous material webs of material (1,5) to form a laminate (12) which includes at least one puckered material layer. A first and second web (1,5) are advanced at different speeds (V.sub.1, V.sub.2) to a web bonding means (4) in which the webs are mutually bonded and the resultant laminate (12) is further advanced at the lower speed (V.sub.2). Because of the difference in speed between the two webs, that web (1) which moves at the higher speed (V.sub.1) at the web bonding moment is puckered while the other web (5) remains smooth. The invention also relates to an arrangement for mutually bonding two material webs (1,5) in accordance with the method, and to an absorbent article (17) which includes a liquid-receiving outer layer (20) which contains at least one puckered, first liquid-permeable layer (21) and at least one smooth, second liquid-permeable layer (22).
