<p>Defibering apparatus for the treatment of waste paper furnishes includes an enclosed tub or tank containing multiple rotors mounted on a common shaft and each provided with a cooperating bed plate. The primary defibering action is effected by the development of zones of intense hydraulic shear in such manner that plastic, wet-strength paper and similar material remains relatively intact while papers of lesser strength are separated into their fibrous constituents. The apparatus is constructed to permit bypassing of the rotors to the extent necessary to assure against damage in the event of the entry of tramp metal or other foreign objects.</p> |
