(54) Apparatus and method for the manufacture of fibrous webs


(57) Apparatus and method for laying down a fibrous web from a foam-fiber furnish. A headbox includes walls defining an elongate channel extending transversley of the direction of movement of the forming wire. Foam-forming nozzles are positioned to introduce foam-fiber furnish into the channel for turbulence - inducing impact on an oppositely disposed wall defining the channel. The turbulently flowing foam-fiber furnish is then introduced to the headbox slice for discharge onto the forming wire with minimized MD orientation of the fibers.
