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 (,) derived from the yarn (,) must be classified in a classification field (,). On the basis of that classification, the extraneous materials contained in the yarn and their types can be determined.
