An apparatus and method is disclosed for dry forming a uniform non-woven fibrous web. The apparatus includes a transport duct, a spreading member and a discharge member connected in series. The discharge member has a flexible plate and a plurality of screws which act upon the flexible plate to deflect its inner surface and provide further control of the basis weight of the to be formed fibrous web. The apparatus also has a forming zone located below the discharge member. The method combines a plurality of individual fibers with a pressurized gaseous stream and routes this stream through the apparatus to form the uniform non-woven fibrous web.
