Abstract: In the process of spinning container head using one-step method, the difficulty in making main shaft and knuckle roll synchronous is that the position of gearing point of main shaft and knuckle roll cannot be easily measured owing to the variation of their gearing point. On the basis of analyzing the range of spinning parameters, the constant power and self synchronous system was creatively designed with adopting the principle of force feedback. The practice indicates that the system is simple and reliable and has significant economic effect. Meanwhile, the principle adopted in this system can be widely applied to the process in which synchronous point varies and its position cannot be easily measured.
