Abstract
A method for making a wound dressing having an absorbent core includes the steps of inserting a plurality of projection elements into a distal surface of the absorbent core such that the projection elements extend into a thickness of the absorbent core and are suitably heated to impart their shape in the absorbent core. The projection elements are removed from the absorbent core to form receptacles therein. A discrete portion of at least one absorbent material is inserted in each of the receptacles.
