    摘要: An apparatus for forming a zoned distribution of particulate material within a fibrous web includes a conveying mechanism for providing a gas entrained supply of the particulate material and a segregating mechanism for centrifugally directing at least a portion of the particulate material into an accumulation region of the apparatus. A transferring mechanism selectively directs particulate material from the accumulation region into a delivery gas stream to provide an intermittent flow volume of a selected quantity of particulate material from the accumulation region through a delivery conduit and into a web forming chamber. A fiberizing mechanism provides a flow of a selected fibrous material into the web forming chamber, and a directing mechanism controls the intermittent flow of particulate material from the delivery conduit into the forming chamber. A foraminous forming layer is disposed within the forming chamber for receiving the fibrous material and the particulate material to produce a fibrous web which includes zoned regions having selected, different amounts of the particulate material therein.

    摘要: 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.
