ABSTRACT:
A yarn tension control apparatus comprising a first feed roll having a substantial conically tapered yarn engaging roll surface, driven at a predetermined r.p.m., a second feed roll having a substantially conically tapered yarn engaging roll surface, the second feed roll positioned in spaced-apart relation with the first feed roll for receiving a yarn wrapped successively around a circumference defined collectively by opposed surfaces of the first and second rolls from a yarn infeed position axially along the first and second rolls to a yarn exit position. The first and second feed rolls are aligned relative to each other so that the collectively defined circumference any any point on the yarn engaging surfaces of the first and second rolls is greater than the collectively defined circumference in one direction along the axis of rotation of the rolls, and less than the collectively defined circumference in the other direction along the axis of rotation of the rolls. An elongate tension arm is positioned between and along the length of the first and second rolls and a plurality of yarn guides positioned in the tension arm along the length thereof for receiving successive wraps of yarn. The tension are moves along the length of the rolls in response to changes in tension of the yarn to a yarn infeed position or increased roll diameter in response to an increase in tension on the yarn and to a position of decreased roll diameter in response to a decrease in tension on the yarn.
