Abstract

See full text

A device for dry forming a web of fibers. The device includes; a fiber distribution head (1); a forming wire (3) movable under the head; a suction means (5) located on the opposite side of the forming wire from the head; within the head, a chamber (9) into which a flow of gas, in which said fibers are suspended, is directed, the chamber having a bottom opening (9A) closed by a screen mesh (17) which is essentially parallel to the forming wire (3) and which faces the the forming wire; and agitator members (45) inside the chamber, above the screen mesh (17), for agitating and distributing the fibers. The screen mesh (17) is a continuous mesh, movable along a closed path around the chamber, the portion of the mesh parallel to and facing the forming wire moving along a path which is essentially parallel to the forming wire. Additionally, the agitator members comprise a plurality of rotating shafts (47) which are parallel to each other and orthogonal to the direction of advance (f3) of the forming wire.
