ABSTRACT:
Method and apparatus for producing defibrated cellulose fluff from bales of stacked compacted wood pulp sheets. A face of such a bale or stack is advanced against a milling cutter. The milling cutter and bale are moved relative to one another in the plane of said face to sweep the cutter across all portions of the face and disintegrate the sheets. Fluff thus produced is drawn through a foraminous screen for further disintegration and defibration of the fluff particles. In preferred embodiments, the baled stack is rotated on a vertical axis over a milling cutter which rotates on a horizontal axis. The milling cutter is mounted beneath a bed having a port through which the periphery of the mill is exposed to the face of the bale.
