Abstract
A method and apparatus for in-line color measurement of continuously moving fiber material, during a fiber material process, by using a color measuring device. The moving fiber material is compressed at a processing position. At the processing position, the fiber material is illuminated by a light probe, thereby defining a measuring position. The light reflected from the fiber material is detected and evaluated to thereby obtain a color measurement of the advancing fiber material.
