Among textile machinery, a winding machine is a kind of preparatory machine and refers to the machine that winds the bobbin with yarn in a uniform density, length and size for the processes required to shuttle less looms, knitting machines, embroidery and sewing machines, etc. From grey yarn to weaving, yarn is wound many times in various ways, and the most important factor in the process of winding is maintaining uniform yarn tension through technology. Therefore, in this study, we researched the high-precision techniques of measuring yarn length very precisely and the yarn winding tension capable of maintaining uniform yarn tension during the winding process by the winding machine. In addition, we configured and verified the high-precision yarn length measurement and the yarn winding tension control system through experimental devices. As a result, we verified the stable control result value of a 50% reduction in average tension for the case of the active disturbance rejection control (ADRC) yarn winding tension control system, and also verified the result that there is about an 80% reduction in yarn length errors after winding 10,000m by the high-precision measurements of yarn length.
