Yongxusheng Electromechanical Technology (Changzhou) Co., Ltd. began to develop the YXS-A automatic warp drawing machine in 2014. The drawing-in speed can reach up to 140 yarns/min, and the warp yarn can be drawn into the drop wires, healds and reeds at one time. The machine is exactly the same as Staubli's Delta110 and is promoted to cotton spinning mills.

As we all know, in the textile industry, the warp yarns must be threaded through the healds and reeds after sizing, and then the warp drop pieces must be hung up before they can be woven on the machine. When weaving with heald frames, the new warp beam yarns must pass through healds and reeds according to the weaving process requirements before being put on the machine. This is the preparation work before weaving in the weaving factory.

The preparation work before warp weaving has a significant impact on the efficiency and weaving quality of automated shuttleless looms, such as air-jet looms, projectile looms and rapier looms, etc., which are mostly used for weaving clothing or technical fabrics. High-quality warp yarns and draw-in are required to meet ever-increasing loom speed and fabric quality requirements. Manual drawing-in work requires workers to have a certain knowledge of weaving technology and pattern weaving technology. The process is very time-consuming and labor efficiency is generally low. Nowadays, few young people choose this job. Therefore, more and more textile factories are introducing drawing machines to replace manual work. This study mainly introduces the basic structure, application history and development trends of automatic warping machines
