Abstract
A method is provided for making absorbent pads that may have a longitudinally asymmetric shape. The pads may be used in various consumer absorbent articles. The method includes delivering a supply of an absorbent web material in a machine-direction and cutting the absorbent web material in a cross-direction to form a repeating nested pattern of generally identically shaped and oppositely oriented absorbent pads, the pads being disposed longitudinally in the cross-direction of the absorbent web. The pads are longitudinally asymmetric and nested such that the crotch portion of one pad is oriented towards the back portions of immediately adjacent pads, and adjacent nested pads share defining cut lines such that there is no wastage of absorbent web material between the nested pads.
