Abstract
Two horizontally spaced parallel shafts (27,28) are rotatably mounted on a base plate (24) having an aperture (27a) therethrough. Each shaft has a plurality of rows of radially extending fingers (36). A casing (38,40) around the fingered portions of the shafts has an inlet throat (44) for receiving shopped strands (16). The shafts are operatively connected by a pair of gears (32,34), and a motor (30) connected to one of the shafts drives the shafts to move the fingers upwardly between the shafts for breaking up clumps of strands and carrying strands of a desired chopped length around the outer sides of the shafts for exit through the aperture. Excessively long strands become wrapped around one or the other of the shafts.
