ABSTRACT:
A fiberization apparatus for treating cellulose, and particularly paper flakes that have been formed from waste paper that has been ground to a certain particle size, by passing the flakes between the sides of a rotating central disc and a pair of stationary discs on opposite sides of the central disc. The rotating disc and the stationary discs have radially extending teeth that taper in depth from a minimum close to the axis of the discs to a maximum near the outer periphery. The facing edges of the teeth on the rotation and stationary discs closely spaced so that as the paper flakes are forced across the teeth, the flakes are disintegrated into loose fibers and the density of the cellulose material is reduced substantially so that it can be used efficiently for insulation purposes.
