Abstract
Abstract The present invention provides an apparatus for disintegrating large bales of material. The apparatus includes a plurality of disintegrating rolls in combination with means for advancing a bale into the rolls. The rolls are arranged in a vertically extending array inclined toward the advancing bale. Behind and above the rolls is an expansion chamber of substantial size into which the material is moved by the disintegrating rolls and from which the material is fed at a substantially constant rate into a cutting chamber and finally to a discharge.
