Abstract
An apparatus for forming deformations in a nonwoven web is disclosed. The apparatus includes a pair of forming members that form a nip therebetween. The forming members include: a first forming member having a surface comprising a plurality of discrete, spaced apart male forming elements; and a second forming member having a surface comprising a plurality of recesses in the second forming member, wherein the recesses are aligned and configured to receive the male forming elements therein, wherein the recesses have a plan view periphery that is larger than, and may completely surround, the plan view periphery of the male elements. At least one of the forming members has a plurality of discrete surface texture elements thereon.
