  • Capillary dewatering method and apparatus
    Patent number: 5701682
    Abstract: Disclosed is a method for reducing the moisture content of a paper web in a papermaking process from in the range of 10% to 32% dry to the range of 33% to 50% dry wherein the embryonic web is supported on a knuckled through drier fabric and lightly pressed between the knuckled through drier fabric and a capillary membrane of a capillary dewatering roll. The capillary membrane has capillary pores therethrough which have a substantially straight through, non-tortuous path with a pore aspect ratio of from about 2 to about 20. A vacuum is drawn within the capillary dewatering roll which is not greater than the negative capillary suction pressure of the capillary pores.
    Type: Grant
    Filed: September 25, 1996
    Date of Patent: December 30, 1997
    Assignee: Kimberly-Clark Worldwide, Inc.
    Inventors: Strong C. Chuang, Kenneth Kaufman, Robert H. Schiesser
