Abstract
An apparatus for depositing fibers on a wire (12) for the production of primarily paper products includes a wire (12) and one or more distributors (1) which are diagonal in relation to the wire (12). This minimizes disadvantages which occur when using traditional apparatuses as, in the present invention, impellers (2) mounted in the distributor (1) are provided in rows (4) which, like the distributor (1), are arranged at an angle between 0.degree. and 90.degree. in relation to the direction of movement (D) of the wire (12).
Claims8
An apparatus for producing a fibrous web having a homogeneous thickness, said apparatus comprising:
- a forming wire which is mounted to move in a straight direction of motion,
- a distributor positioned adjacent to said forming wire to distribute fibers thereon, said distributor comprising
- a housing which defines an open end facing said forming wire,
- a net which is mounted on said housing to cover said open end,
- means for supplying fibers to said housing, and
- a plurality of impellers located within said housing and rotatable around axes which extend perpendicularly to a plane formed by said forming wire as said forming wire passes by said open end of said housing, said plurality of impellers being aligned in at least two parallel rows which extend at an angle of greater than 0.degree. and less than 90.degree. to said straight direction of motion of said forming wire, said impellers distributing air-suspended fibers towards and through said net for deposition on said forming wire.
