  • Paper forming activity blade
    Patent number: 6030501
    Abstract: A papermaking apparatus such as a Fourdrinier table which includes a long blade and a trail blade. In the first aspect of the invention, the long blade includes an upper undulated surface with vents passing from the upper undulated surface to the lower surface of the long blade which is at substantially atmospheric pressure. In the second aspect of the invention, the trail blade includes an elevator-type device for adjusting the vertical position of the trail blade. In a third aspect of the invention, a single elevator is used to adjust the angle of the blade, the blade is provided as a modular or multiple-piece design, mounting buttons are used to engage slots of T-shaped cross section in the blade and/or ceramic inserts are included at wear points.
    Type: Grant

  • Velocity induced drainage method and unit
    Patent number: 5951823
    Abstract: A drainage device and method which provides for drainage from paper or pulp stock on a fabric in a sheet or mat making machine which includes a primary blade and trail blade with a gap therebetween for drainage wherein the size of the gap controls drainage and the primary blade is so configured so as to force a portion of the drained liquid through the fabric to create paper stock activity and disbursement while minimizing turbulence and maintaining laminar flow in the machine direction along with providing reinforcement of CD shear.
