Abstract

A process of making an absorbent article comprising providing a liquid permeable topsheet web extending substantially continuously in a machine direction. The topsheet web having a first and second surface and a backsheet web extending substantially continuously in the machine direction and an acquisition layer having a first and second surface. The process comprises aligning the topsheet web and the acquisition layer in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the acquisition layer and simultaneously mechanically deforming and combining the topsheet web together with the acquisition layer. The topsheet web and acquisition layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the acquisition layer to provide a topsheet/acquisition layer laminate web having three-dimensional protrusions.
