  • Patent number: 4734164
    Abstract: A system for forming a web from a dilute, aqueous slurry of fibers wherein a thin, horizontally-extending aqueous stream of fibers is projected onto a travelling foraminous forming wire. The forming wire is disposed to travel over a forming board which has a leading lip which is deflected downwardly with respect to the oncoming jet stream. The lower surface of the jet stream is disposed substantially parallel with the surface of the travelling foraminous wire wire at the point where the stream contacts the wire to minimize turbulence at the point of initial contact of the jet stream on the wire and subsequent spouting of the fibrous stock downstream in the forming zone.
