The function of the yarn feeding mechanism is to take the yarn out of the bobbin and feed it into the weaving area, which has two types: negative and positive. Negative yarn feeding is caused by tension to pull the yarn out of the bobbin. Although the tensioner and the tension compensating device control the tension and the amount of the yarn, the yarn tension difference is still large. The active yarn is fed by a special device to feed the yarn into the weaving zone at a constant linear velocity with a small difference in yarn tension.
