ABSTRACT:
A free-floating ring is disposed in an annular chamber between a fixed outer ring based on the ring rail and an inner ring which is adjustable up and down axially in relation to the outer ring. The outer ring has circumferentially spaced camming slots in its side wall slidably receiving radial cam pins fixed to the inner adjustable ring. One such cam pin on each inner ring is extended to engage slidably within a slot in an actuating bracket secured to a shifter rod extending longitudinally of the ring rail and guided within bearings on the ring rail. Movement of the shifter rod longitudinally of the ring rail in one direction or the other produces raising or lowering of the gang of inner rings to vary the yarn tension. An opening for yarn threading is provided in the annular side wall of each outer ring.
