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.
Une station de formation par voie pneumatique forme un non-tissé à partir d'un premier matériau et d'un second matériau ayant au moins une caractéristique physique sensiblement différente. Ladite station de formation par voie pneumatique comprend une chambre de formation et un écran de formation qui se déplace par rapport à la chambre de formation et sur lequel se dépose le premier et le second matériau. Un premier distributeur amène le premier matériau. Une source de vide crée un courant d'air qui fait déposer le premier matériau sur l'écran de formation. Un second distributeur amène le second matériau, indépendamment du premier matériau, entre le premier distributeur et l'écran de formation, par gravité le long d'un ou de plusieurs déflecteurs.
