  • Method for monitoring yarn tension in yarn manufacturing process
    Patent number: 6014104
    Abstract: The yarn manufacturing process is monitored by detecting a yarn tension while the yarn spun by a spinning device is wound by a winding device. The yarn tension detected by the yarn tension sensor is corrected based on the rate of change in a winding condition such as a traverse speed or a winding speed, and whether the yarn manufacturing process is in a normal condition or not is judged based on the corrected tension. Also, an abnormal judging reference is corrected based on the rate of change in a winding condition, and whether the yarn manufacturing process is in a normal condition or not is judged based on the corrected abnormal judging reference.
