Abstract
A headbox for suspension having an inlet, an outlet and a suspension guide within the headbox. The headbox provides three layers of suspension. A first transverse suspension supply distributor extending laterally across the headbox for supplying the middle layer of suspension. A second transverse distributor extending across the lateral width of the headbox, of a generally horseshoe shape for partially enclosing the first distributor and the legs of the U of the second distributor providing suspension for the outer two layers of the three layers. The suspension supply to each distributor is either from the same lateral side or from opposite lateral sides of the headbox. Each distributor tapers narrower in cross section from the suspension supply at one side toward the opposite lateral side. The guide in the headbox is at each of the three layers.
