METHOD FOR CONTINUOUS DETERMINATION OF THE PROPERTIES OF A FLOW OF WOOD FIBRES FOR FABRICATION OF FIBREBOARD

摘要

In a method for continuous determination of the properties of a wood fibre flow (2) in fibreboard fabrication, a sample of the fibre flow is illuminated with light, and one or more of the properties fibre length distribution (20, 22), resin content (14), fibre moisture (16) and optical properties (18) for the sample, determined from the measured ensuing reflectance spectrum, is/are determined from predetermined relations between measured spectral values and absolute magnitudes for said properties.
