Discusses a method and apparatus to achieve a desired distribution of superabsorbent polymer (SAP) or any other particulate material in an absorbent pad of disposable absorbent articles. Specifically it strikes a compromise between the desire for homogeneous distributions for product performance, and layered distributions for minimizing SAP losses in the converting process. The particulate distribution achieved can generally be described as a statistical bell curve (normal distribution) in the thickness (or Z-direction) dimension. The result is well mixed SAP with significantly diminished particulate concentrations on the top and bottom of the pad.
