Method and apparatus for determining the structure of yarns in the region of their surface |
摘要 |
The surface of a yarn (G) is imaged on a sensor (7) having a plurality of sensor elements of differing structural arrangement. The signals of the individual sensor elements are compared with one another, and the structure of the examined yarn surface is determined on the basis of correspondence with the appropriate sensor element. The structure to be examined is formed both by the actual yarn surface and by the yarn edge, including projecting fibers and possible impurities, such as foreign fibers, included in the yarn.
