Abstract
Apparatus is provided for separating cellulose fluff fibers from waste fibrous material resulting from the manufacture of absorbent products from cellulose fluff fibers, comprising: an apertured cylindrical separator disposed in a housing and having a central passage in flow connection with the inlet; the cylindrical separator having apertures therethrough large enough to permit cellulose fluff fibers to pass therethrough but small enough to screen out larger non-fluff material from the waste fibrous material; means in connection with the first outlet for controlling flow therethrough of air and entrained waste fibrous material, for providing a balance between flow rate and differential pressure across the apertured separator sufficient to prevent blockage of the apertrues in the separator by waste fibrous material too large to pass through while permitting cellulose fluff fibers to pass through.
