Abstract
A method of making an absorbent article with a waist relief area includes providing a web of outer cover material moving in a machine direction; cutting a plurality of first relief holes in the web of outer cover material; at least partially covering the plurality of first relief holes with an overlay material to define a fringe; and cutting the web of outer cover material in a cross-machine direction to define a plurality of discrete absorbent articles wherein each cut extends through each first relief hole. The fringe may be made from the waist elastic material, liner material, fastening material, or facing material. The fringe may also be cut with a plurality of second relief holes having an area smaller than the area of the first relief holes.
