Abstract
A process for making a necked nonwoven web having improved cross directional uniformity includes the steps of passing a nonwoven web between a first nip having a first surface velocity and a second nip having a second surface velocity, necking the nonwoven web between the first and second nips, and selectively increasing the necking of a central region of the nonwoven web relative to two edge regions or selectively decreasing the necking in the edge regions. The selective increase in necking in the central region or selective decrease in necking in the edge regions offsets the relatively higher necking in the edge regions which is inherent in conventional necking processes. A process for making a laminate having improved cross-directional uniformity is also provided.
