Abstract:
An apparatus for feeding a yarn from a yarn supply to a reciprocating needle comprising:a driven roller having a longitudinal axis and a periphery; and a first dual yarn feeder including a first yarn feeder component and a second yarn feeder component, the first yarn feeder component disposed for selectively moving into peripheral engagement with the driven roller at a longitudinal location along the longitudinal axis of the driven roller and at a peripheral location about the driven roller periphery, and alternatively, moving out of peripheral engagement with the driven roller, such that when the first yarn feeder component is in peripheral engagement with the driven roller, the driven roller drives the first yarn feeder component and causes the first yarn feeder component to feed the yarn, the second yarn feeder component disposed for selectively moving into peripheral engagement with the driven roller at the longitudinal location along the longitudinal axis of the driven roller and at a second peripheral location about the driven roller periphery displaced from the first peripheral location, and alternatively, moving out of peripheral engagement with the driven roller, such that when the second yarn feeder component is in peripheral engagement with the driven roller, the driven roller drives the second yarn feeder component and causes the second yarn feeder component to feed the yarn.
