[0002] The warp tying machine usually refers to the automatic warp tying machine (or warp machine), which is a device used in looms, mainly used to pass the warp yarn through the weaving mouth on the fabric to form the warp of the fabric during the weaving process. This process is usually called "warping". The working principle of the automatic warp tying machine is usually to take the warp yarn from a spindle or a bobbin in an automated way, then pass it through the weaving mouth of the loom, and finally fix the warp on the other side of the loom. In this way, the loom can start the weaving operation. The use of automatic warp tying machines can greatly improve the efficiency of weaving, reduce the demand for manual labor, and ensure that the warp threads pass through the fabric correctly, thereby improving the quality and consistency of the fabric. This equipment is usually widely used in places such as textile mills and fabric factories. At present, there are many textile fabrics and the cords are of different thicknesses.
