Abstract
An apparatus for making a sheet formed fiber product includes at least one fiber distributor (1) having a substantially planar bottom (7) in the form of a wire net, with openings approximately formed as parallelograms; an endless forming wire (2) having an upper and an lower run, the upper run being situated a short distance from the underside of the bottom (7) of the fiber distributor (1), and at least one suction box (3) situated in such a way in relation to the upper run (2) of the forming wire that fibers passing through the bottom (7) of the fiber distributor are disposed onto the upper side (2) of the forming wire in the form of a coherent fiber layer.
