1. An apparatus for applying particulate powder material to a substrate of fibrous material comprising:

  • conveyor means for supporting and moving said fibrous substrate in a horizontal path at a predetermined rate;

    feeder means having an inlet means and an outlet means, wherein said inlet means receives said particulate powder material and said outlet means is connected to a continuously operating nozzle for producing a continuous stream of said particulate powder material;

    said nozzle being movable between a first position and a second position at a predetermined rate, said nozzle having an outlet for alternately directing said continuous stream of particulate powder material toward a predetermined location of said fibrous substrate and toward a diverter means; and

    said diverter means disposed above said conveyor means for intermittently receiving the continuous stream of particulate powder material from the nozzle to separate the stream into first and second intermittent streams of particulate powder material,whereby said first intermittent stream is applied to said fibrous substrate moving at said predetermined rate and at said predetermined location of said fibrous subsrate to form a layer of particulate powder material within a predetermined portion of said fibrous substrate.
