The present invention is able to detect yarn defects with great accuracy by measuring the tension of the yarn.

The present invention holds the fastened spun yarn in a bent state by a tension sensor immediately before the winding package. The changes in tension of the fastened spun yarn are measured by this tension sensor and the evaluation of yarn defects is performed by an evaluation part based on the results of this measurement.
