Abstract:
A two-component nozzle (200) for the pneumatic delivery of solid particulates is disclosed. The nozzle generally includes an inner conduit (210) for conveying solid particulates such as superabsorbent polymer particles and an outer conduit (220) for conveying an outer airflow that is directed via a foraminous plate (300) into the path of the solid particulates exiting the nozzle. The outer airflow improves the weight distribution of the solid particulates as they are deposited onto a substrate to form a composite material. The nozzle (200) can optionally deliver other components such as fluff, binders, and water in addition to the solid particulates. A production process for the composite material, suitable for inclusion in an absorbent articles, also is disclosed.
