ABSTRACT:
Yarn tensioning apparatus particularly suitable for receiving essentially tensionless yarn and giving it a generally uniform output tension level includes friction surfaces across which the yarn is drawn to progressively raise the tension level and work out tangles. The tension surfaces are long, so that, in passing transversely over them, the yarn may take a variety of paths to accommodate the abrupt fluctuations associated with tangle release events. Near the output, a member having a friction nose at one end is pivoted at its opposite end and includes a curved intermediate portion that may swing down to contact a yarn engaging portion of a friction pin; the arrangement being such that an increase in yarn tension causes movement of the member relative to the pin in a direction to produce tension-reducing effects, and vice versa.
