ABSTRACT:
A method for applying particulate powder material to a moving, pre-formed, fibrous substrate. In this method, particulate powder material is entrained in a continuous airstream. The air-entrained stream of particulate material exits a nozzle to be applied to the substrate or recirculated. The stream of air-entrained particulate matter has a velocity component in the direction of movement of the fibrous substrate.
