  • Method for the continuous production of chip, fiber-and similar boards
    Patent number: 4946635
    Abstract: A method for the continuous production of chip board in which a mixture of cellulose chips and resin binder is compressed against a heated rotating drum by a steel band. A first pressure of 250-325 kilopond per centimeter (1 kp=1 kgf) is applied to the mixture at a first position on the heated drum. A second pressure of 400-475 kp/cm is applied at a second position to compress the mixture to the final thickness as the binder hardens and binds the chips.
