[0002] The development and application of shuttleless looms such as rapier looms, air-jet looms, and projectile looms has brought the output of the textile industry to a new level. Among them, popular shuttleless looms are popular among small and medium-sized enterprises because of their low price. However, due to the structural characteristics of the weft insertion mechanism during the weaving process, the popular shuttleless looms have raw edges and cannot form natural weft yarns into the selvedges during the weft insertion process like shuttle looms. While affecting the textile effect, post-processing such as cutting, hemming, and sewing is required, which not only takes a lot of time and labor, but also wastes a lot of raw materials, which greatly increases the production cost of textile enterprises.
[0003] In order to achieve the smooth edge requirements of fabrics, mechanical tuck-in devices or pneumatic and mechanical tuck-in devices are added to some shuttleless looms, which are only suitable for low-speed looms due to the instability of the mechanical parts. Moreover, the mechanism is easily damaged, the weft insertion rate is low, and the length of the burrs that can be folded in is too long, etc., which greatly affect the production efficiency.
[0004] The success rate of the current pure pneumatic tuck-in device has been guaranteed, but it is still necessary to test the tuck-in of different yarns under different conditions
