  • Attrition mill and method of fibrous web formation
    Patent number: 3940831
    Abstract: Apparatus and method for forming a fibrous batt of controlled thickness and uniformity with fibers flowing from the discs of an attrition mill. The fibers are directed from the outlet of the mill in an air stream in a path of decreasing radius of curvature so that the fibers accelerate toward a collecting screen until they reach a forming chamber communicating the path with the screen. The acceleration of the fibers in the path prevents fiber contact and minimizes fiber contact with walls of the equipment thereby avoiding fiber agglomeration.
