Development of Ribbons --Spinning

After the weft tube is formed by warp winding and weft winding, the weft tube is inserted on the fixed teeth base of the Spinning machine. The weft tube rotates along the 8-shaped track to pull the yarns to cross-weave. Usually the number of spindles is even, the ribbon is tubular, the number of spindles is odd, and the ribbon is flat. Ingot weaving technology was used in old China. The number of ingots varied from 9 to 100 ingots due to different equipment. The basic process of weaving was bleaching, weft winding, weaving, shearing and packaging. Since 1960, many technological innovations have been carried out on the knitting machine, such as enlarging the diameter of peach board, installing automatic stop device for broken rubber band, and changing the iron ingot into nylon ingot. With the improvement of these equipments, the vehicle speed has been raised to 160-190 rpm, the stand rate has doubled, and the product quality has been greatly improved.

Spinning can not only knit ribbons, but also knit ropes. Tube ribbon is a kind of braided rope, which is called rope or rope with a diameter of 1-4 mm, and rope with a diameter of more than 4 mm. The rope with a diameter of more than 40 mm is generally called cable or rope. In 1989, the industry introduced the equipment of Japan's Eight-strand cable production line and produced polypropylene Eight-strand cable the following year. The product won the National Silver Award.
