Abstract

An electronic device for locates a functional disorder within a spinning and winding section of a spinning by receive spinning parameters from spinning machines related to production of yarn delivery bobbins at the spinning machines, and receiving winding parameters from winding machines related to production of yarn bobbins at the winding machines. For the yarn bobbins, the electronic device compares a winding parameter with a normal state level value for the winding parameter to detect a winding abnormality at the respective winding machine that produced the yarn bobbin. Upon detection of the winding abnormality, the electronic device the yarn delivery bobbins used for production of the yarn bobbin and compares at least one of the spinning parameters of the identified yarn delivery bobbins with a normal state level value to locate the functional disorder within the spinning and winding section.
