Spinning machine drafting mechanism have different walking frame spinning machine and go spinning machine essence is the same. The difference is walking frame spinning machine in work is creel do reciprocating motion, go spinning machine in the work spindle do reciprocating motion, walking frame spinning machine and walking machine spindle fine yarn spinning mechanism is the same but their mechanism of spinning and ring spinning machine of spinning mechanism is different. The main difference lies in the spinning machine drafting, twisting and winding are the three main processes in different ways, in spinning frame machine and a mule, drafting and twisting in the horizontal direction of and the twisting and winding process is not at the same time, the twisted without winding and winding when not twisting. And for ring spinning frame, drafting and twisting is basically in the vertical direction and twisting, the process of drafting and winding is at the same time, therefore the production efficiency more high, walking frame spinning machine and spinning machine is horizontal, the draft is longer, usually through a spindle applied twist. Spindle and roving plane almost perpendicular, but slightly forward, in drafting and twisting process, spindle rotation of the yarn on a spindle upper detachment, twist is added to the roving instead of roving reel to cop, some people believe that this flick action helps to twist distribution, formed to draft the vibration. Common wool woolen spinning machine has three main types, walking frame spinning machine, spinning mode of spinning and ring spinning machine, the three spinning machine corresponding respectively to frame spinning, spinning and ring spinning, for the performance of the pros and cons of the comparison of the three kinds of spinning machine yarn, walking frame spinning machine and spinning frame spinning lines evenness is superior to ring spinning machine, but production efficiency is lower than the ring spinning machine. Spinning performance and the effects of three kinds of spinning machine may vary over time, when in use, it can use the device according to the batch size, quality and variety of customer requirements is selectively and effectively play its effectiveness to reduce unnecessary maintenance.
