ABSTRACT:
A yarn tension device comprises a ball 10 resting on an annular seat 12 to define therebetween a yarn path whereby yarn 14 drawn along that path is tensioned. A preloaded torsion spring 22 acts on the ball 10 to exert a resilient bias thereon to urge the ball 10 against the seat 12. A control 28 is provided for varying the preloading of the torsion spring 22. The device provides a readily variable yarn tension that has a surprising constancy from one device to the next.
