  • Method of selecting and/or processing wood according to fibre characteristics
    Patent number: 6773552
    Abstract: The invention provides a method for predictively assessing one or more characteristics of wood pulp produced from solid wood. The method comprises the steps of determining the velocity of sound through the solid wood, and assessing characteristic(s) of wood fiber or wood pulp produced from the wood by reference to the velocity of sound through the solid wood. The method may also comprise the steps of causing a sound wave to be transmitted through the wood, determining the velocity of the sound wave through the wood, and comparing the result to stored information on fiber characteristic(s) versus sound velocity through the wood-type to determine the fiber characteristic(s) for the wood.
