A ravel in a fast moved plastic fiber bundle should be detected. At this, an optical fiber through beam head is placed in way, that the normal plastic fiber bundle stream does not cover the optical beam. However, if a ravel appears, the optical beam will be partly interrupted and this leads to a decrease of the receiver signal.
