Patent number: 5156902Abstract: 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.Type: GrantFiled: December 17, 1991Date of Patent: October 20, 1992Assignee: Kimberly-Clark CorporationInventors: Christopher M. Pieper, Jeffrey W. King, Bruce R. Shafer, Robert A. Stevens, Timothy L. Wehman, Edward E. Werner

Patent number: 4258455Abstract: A process and mechanism for the dry screen forming of fibers to attain a dispersion in air of substantially individual fibers from which a fibrous sheet is formed. Fibrous nits, pills and flocs are removed from the dispersion by rolling the nits, pills and the like into elongated shapes as they pass a fiber screening member and carrying the elongated fibrous bodies from the dispersion of fibers and away from the sheet forming area for the fibers. The mechanism includes a fiber screening member, a fiber receiving member on which the sheet is formed and a foraminous member which rolls the nits, pills and the like between it and the fiber screening member as the air dispersion of fibers passes toward the fiber receiving member.Type: GrantFiled: January 18, 1979Date of Patent: March 31, 1981Assignee: Kimberly-Clark CorporationInventor: Edward E. Werner

Patent number: 3966126Abstract: An apparatus and method for processing fibrous material into fluff and substantially individual fibers. The apparatus includes a hammermill having an impermeable wall of grid-like configuration against which fibrous material to be fiberized is thrown by impact element rotation. The fibrous material is conveyed through the mill in an air stream which defines a general path for the fibrous material under the influence of impact element rotation. The grid-like wall serves to slow the particles of fiber rebounding from the wall so that the particles are subjected to repeated impacts by the impact elements of the mills. Rings divide the interior of the hammermill to control the fiber flow in the air stream to the outlet. A pair of hammermills in sequence permits pulps which are difficult to defiberize to be readily reduced to fluff.Type: GrantFiled: February 10, 1975Date of Patent: June 29, 1976Assignee: Kimberly-Clark CorporationInventor: Edward E. Werner

Patent number: 3940831Abstract: 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.Type: GrantFiled: December 13, 1974Date of Patent: March 2, 1976Assignee: Kimberly-Clark CorporationInventors: Edward E. Werner, Jerome L. Mitchell
