1. A method of making absorbent articles, comprising the steps of:

  • providing a continuous substrate layer having a uniform width;

    providing one or more streams of adhesive fibers and superabsorbent particles;

    shaping at least the one or more streams of adhesive fibers;

    depositing the adhesive fibers and superabsorbent particles continuously on the substrate layer to form a plurality of non-rectangular absorbent cores end-to-end and bound to the substrate layer;

    separating the absorbent cores from each other; and

    collecting and recycling loose superabsorbent particles;

    wherein the non-rectangular absorbent cores are formed and shaped on the substrate layer without cutting lateral side edges of the absorbent cores, each non-rectangular absorbent core has an average width in an end region that is at least 10% greater than an average width in a central region thereof and less than the width of the substrate layer, and the lateral side edges of the absorbent cores have a fuzzy or serrated configuration of laterally extending peaks and valleys defined by a P/EL greater than or equal to 1.50 and a MDMFE greater than or equal to 1.0 mm.
