摘要: An apparatus for measuring the lateral yarn density distribution of a yarn uses selected X-ray radiation. Radiation absorption is determined in a number of narrow planes across the yarn and in two or more rotational orientations. The measuring takes place without any damage to or physical interference with the yarn.
