Yarn texturing device, yarn texturing method and winding package employing quality indicating function

Abstract

The object of the present invention is to allow the reliable identification of the quality level of the winding package based on the yarn quality such as the yarn winding tension or the twisting density when manufacturing a winding package. According to the draw texturing machine for winding while traversing the false-twist textured yarn Y unwound from the supply yarn package and forming a winding package of taper end form, a tension sensor for detecting the tension of the yarn Y to be processed into a winding package and a quality level judging means for judging the quality level of the winding package based on the detected tension information, are provided. Moreover, a winding controller is provided with a winding terminating position setting means for coordinating the quality level judging means and the traverse device T so that the straight winding position (b )˜(b ) at the finishing of the winding process of the winding package is to be determined in the differing axis direction based on the judged result of the quality level judging means
