    Abstract: In a method for manufacturing the fiber-containing article, the discontinuous fibers, intermingled with fibers serving as a binder, are couched into a fiber mat in such a manner that the discontinuous fibers are advanced into contact with an air flow which carries them up to a conveying level where the fibers become randomly directed and the fiber-carrying air flow is passed through this level.
