Abstract
The yarn is wrapped around and between a driven tensioning pulley and a small freely rotatable separator pulley, and a radial arm is pivotal about the tensioning pulley axis at one end and carries a guide roller at the other end. As the arm is rotated the guide roller contacts the yarn wrap and progressively lifts it clear of the tensioning pulley surface, thereby progressively decreasing the arc of contact between the tensioning pulley and the yarn, and decreasing the yarn tension. Rotating the arm in the opposite direction increases the yarn tension.
