This paper is about how to design an improved anti-ribboning method for the winder system. The system is based on the principle of a brushless DC motor control, which constantly changes relative velocity between the grooved drum and the yarn bobbin. This in turn, causes the changing of the winding ratio value. Therefore, it will accomplish the anti-ribboning control. Compared with the traditional anti-ribboning methods, the improved method can save more mechanical components and maintenance costs. Also, this method can develop different programs for different yarns. Therefore, this method is more efficient and versatile. |
