ABSTRACT:
A fiber fluff generator includes a housing having three substantially cylindrical portions, each of which mounts and contains a rotor having a rotor shaft and a plurality of rotor pins extending radially therefrom. The rotor pins are arranged in rows spaced incrementally along the length of the shaft with gaps therebetween, each row including plural rotor pins arranged in spoke-like fashion. The rotor shafts preferably are mounted parallel to one another and lie in a common vertical plane. The rotor pins on one rotor shaft are axially offset from and overlap with the rotor pins on the adjacent rotor shaft(s) so that the rotor pins collectively are interleaved to provide a cross-combing effect. Stator pins fastened to the housing extend radially inwardly into the gaps between the rows of rotor pins to provide further cross-combing interaction. As the rotors rotate, fiber introduced into an inlet at the top of the housing flows downwardly toward an outlet located at the bottom of the housing while it is fluffed and combed by the three-stage rotor arrangement.
