In winder, yarn tension device is installed in the back of the yarn should be vertically through the metal sheet between the gap, must not be in the yarn in the yarn twists and turns, because of the twists and turns of the case, especially when the speed is high, the yarn will be excessive friction caused by the very high breakage rate.
Adjust the yarn device slot, can use a set of different thickness of the metal plate and the distance to a piece of work.
During winding, attention should be paid to clearing up fuzz, dust and debris accumulated on the yarn clearer, and equipped with a special blowing and dust collecting device on the modern winder.
In the past, a mechanical cleaning device was used in the winding process. It has the advantages of simple structure, low cost, not affected by temperature and humidity, influence the knot, larger on the fly, weaving leaves can also be cut down or removed, but easy to shave yarn, damage to fiber, and a flat state of yarn faults tend to leak past, clearing efficiency is low, generally only about 30%.
Electronic yarn clearer is used to remove yarn faults with electronic equipment. Its structure is complex and its cost is high. However, because it is not contacted with yarn, there is no drawback of shaving yarn and bad fiber. Especially when the speed is higher than 600 m / s, it can still maintain about 80% of the yarn cleaning efficiency.
