Abstract:
A method for making a zoned apertured nonwoven web comprises providing an unapertured nonwoven web having a first plurality of weakened locations in a first pattern in a first zone and a second plurality of weakened locations in a second pattern in a second zone. The method comprises applying a substantially cross machine directional tensioning force to the nonwoven web to cause the nonwoven web to rupture at some of the first and second pluralities of weakened locations. The applying step creates a plurality of first apertures in the nonwoven web coincident with the some of the first plurality of weakened locations and a plurality of second apertures in the nonwoven web coincident with the some of the second plurality of weakened locations. The cross machine directional width of the nonwoven web after the applying step is substantially the same in the first zone and the second zone.
