  • Process and device for monitoring the quality of yarns
    Patent number: 6244030
    Abstract: The invention relates to a process and device for monitoring the quality of yarns. In order to differentiate extraneous materials in a yarn section front the yarn itself and from other extraneous materials more effectively, a signal (10) derived from the yarn (8) must be classified in a classification field (16). On the basis of that classification, the extraneous materials contained in the yarn and their types can be determined.
