Abstract
Aspects of the methods herein relate to the fabrication of absorbent articles wherein a continuous topsheet web is advanced in a machine direction. A liquid acquisition layer and an absorbent core are combined with the continuous topsheet web. The combined continuous topsheet web, liquid acquisition layer, and absorbent core advance through the embossing nip to emboss a pattern in the continuous topsheet web. As the combined continuous topsheet web, liquid acquisition layer, and absorbent core advance through the embossing nip, the rotating patterned embossing roll contacts the continuous topsheet web. And the rotating anvil roll contacts the absorbent core. By advancing the topsheet together with the acquisition layer and absorbent core through the embossing nip, a relatively deep pattern can be embossed into the topsheet than otherwise might be possible when embossing relatively thin topsheet web materials.
