  • Papermaking refiner plates and method of manufacture
    Patent number: 7614129
    Abstract: Replaceable refiner fillings used for refining of lignocellulosic and other natural and synthetic fibrous materials in the manufacture of paper, paperboard, and fiberboard products. The refiner fillings include a pattern of blades and spacers defined by a bar cluster, with the bar cluster being the basis of formation of the filling. A method of manufacture provides bar cluster patterns based on factors including pumping angle, plurality of segments in a refiner filling, and the number of clusters in a segment. A bar set cluster is established for uniform fabrication of bar clusters for the refiner fillings.
    Type: Grant

  • Papermaking refiner plates and method of manufacture
    Patent number: 6935589
    Abstract: Replaceable refiner fillings (10) used for refining of lignocellulosic and other natural and synthetic fibrous materials in the manufacture of paper, paperboard, and other fiberboard products. The refiner fillings (10) include a pattern of blades (14) and spacers (16) defined by a bar cluster (24), with the bar cluster being the basis of formation of the filling (10). A method of manufacture provides bar cluster patterns based on factors including pumping angle, plurality of segments in a refiner filling (10), and the number of clusters in a segment. A bar set cluster is established for uniform fabrication of bar clusters (24) for the refiner fillings (10).

  • Papermaking refiner plates
    Patent number: 5954283
    Abstract: Replacable refiner plates used for papermaking and refining of lignocellulosic and other natural and synthetic fibrous materials in the manufacture of paper, paperboard, and fiberboard products. The refiner plates include blade patterns and use corrosion resistant materials, as well as ceramic and ceramic composite materials. The blades and spacers overlap to define intercontacting surfaces with the blades and spacers metallurgically bonded throughout the intercontacting surfaces.
