Abstract

An air laying forming station (ALFS) forms a nonwoven substrate from a first material and a second material having at least one physical characteristic substantially different from the first material. The ALFS includes a forming chamber and a forming screen, moving relative to the forming chamber, for receiving deposit of the first and second materials. A first distributor supplies the first material. A vacuum source provides an air flow which deposits the first material onto the forming screen. A second distributor delivers the second material, independently from the first material between the first distributor and the forming screen, by gravity along one or more baffle members.
