ABSTRACT:
An anti-static tension device for maintaining tension and drag on yarn and for reducing static on the yarn, as the yarn is supplied from a yarn bobbin supply to the creel of a knitting or weaving machine. The anti-static tension device includes a mounting clip for mounting the anti-static tension device on a creel; and an anti-static disc having a hole therein for receiving a collar. The collar has a first passageway for receiving yarn from a yarn bobbin supply, and the anti-static disc is formed of a non-static plastic material to reduce static on the yarn. The anti-static tension device further includes a tension assembly connected at one end to the mounting clip for mounting to a creel and at the other end thereof to the anti-static disc. The tension assembly includes a tension bracket, a needle shaft mounted on the tension bracket, the needle shaft having a second passageway formed therein in alignment with the first passageway and for receiving yarn, upper and lower tension discs mounted on the needle shaft and defining therebetween a pathway for receiving yarn in alignment with the first and second passageways. The tension assembly further includes a third passageway in alignment with the first and second passageways for receiving yarn and supplying it to the creel; and a gravity tension member for maintaining the upper and lower tension discs in contact with the yarn to maintain tension and drag on the yarn.
