Warp threading and warp knotting are the last process of warp yarn preparation, the purpose of which is to pass the warp yarn wound on the warp beam through the heddle and reed sequentially according to the design of the process requirements to meet the requirements of the weaving process. The heald frame is made up of heald wire, heald frame and heald screw rod. The function of the reed is to determine the warp yarn density of the fabric, beat the weft yarn to the fabric fell, and also serve as a guide for the shuttle when it passes through the shed. At present, domestic wool spinning is still mainly based on manual drafting.

As the labor cost of the factory is getting higher and higher, and the difficulty of recruiting is becoming more and more difficult, the traditional semi-automatic small prototype machine is gradually unable to meet the production needs of the factory, and the use of fully automatic small prototype machines is becoming more and more widespread. They are all relatively expensive, and the price of each one is more than 100,000 yuan. If you directly thread the heald on the fully automatic small prototype machine, the result is that it takes more than an hour to thread the heald, while weaving only takes ten minutes, which cannot give full play to the fast performance of the fully automatic small prototype machine. .
