  • Patent number: 4100018
    Abstract: A method and apparatus for continuously forming a fibrous web in which a fibrous suspension is injected into a tapered throat formed by two running wires pervious to the suspension and converging to the periphery of an impermeable roll; the wires and the injected suspension therebetween are transported over a portion of the periphery of the roll under tension to form and dewater the injected suspension; as the wires run off the forming and dewatering roll, the web is sucked loose from the outer wire and it and the wires are transported over a convexly curved surface under tension; and the web is separated from the outer wire by off-running in the direction away from the convexly curved surface while the inner wire runs off that surface with the web, the convexly curved surface being impermeable at least at the wire separation location.

  • Patent number: 4081320
    Abstract: The transfer of a fibrous web in a paper-making machine from a first foraminous belt to a second foraminous belt is facilitated by applying water to the side of the first belt opposite from the side on which the web is carried partially to wet the web, leading the second belt into engagement with the fibrous web before or after wetting it, and after the web is wet, and while the second belt is in engagement with the web, causing the water or gas pressure on the side of the web adhering to the first belt to exceed the water or gas pressure on the side of the web adjacent to the second belt.
