Apparatus for aerodynamically forming a fibrous sheet material

An apparatus for making sheets of fibrous material in a chamber having perforated top and side inner walls into which an air stream mixture with fibers therein is introduced through a nozzle over a travelling screen conveyor on which the fibers are settled to form a mat thereon. The chamber has soli...

Beschreibung
Zusammenfassung:	An apparatus for making sheets of fibrous material in a chamber having perforated top and side inner walls into which an air stream mixture with fibers therein is introduced through a nozzle over a travelling screen conveyor on which the fibers are settled to form a mat thereon. The chamber has solid outer walls defining a space over the chamber and on the sides thereof into which air under pressure is introduced to keep the fibers in the chamber from contacting the inner walls and becoming electrostatically charged. The apparatus is provided with mechanism for applying a vacuum through the air-permeable conveyor to settle the fibers thereon and for forming a sheet of fibrous material thereon.
