Abstract
A device for dry forming a web of fibers. The device includes; a fiber distribution head (); a forming wire () movable under the head; a suction means () located on the opposite side of the forming wire from the head; within the head, a chamber () into which a flow of gas, in which said fibers are suspended, is directed, the chamber having a bottom opening (A) closed by a screen mesh () which is essentially parallel to the forming wire () and which faces the the forming wire; and agitator members () inside the chamber, above the screen mesh (), for agitating and distributing the fibers. The screen mesh () 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 () which are parallel to each other and orthogonal to the direction of advance (f) of the forming wire.
