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 (22). The forming wire (22) is disposed to travel over a forming board (26) which has a leading lip which is deflected downwardly with respect to the oncoming jet stream (l5). The lower surface of the jet stream (l5) is disposed substantially parallel with the surface of the travelling foraminous wire (22) at the point where the stream contacts the wire (22) to minimize turbulence at the point of initial contact of the jet stream (l5) on the wire (22) and subsequent spouting of the fibrous stock downstream in the forming zone. |
