Abstract:
An apparatus for feeding a yarn from a yarn supply to a reciprocating needle comprising:a driven roller;a yarn feeder disposed for selectively moving into peripheral engagement with the driven roller, and alternatively, moving out of peripheral engagement with the driven roller;an actuator for moving the yarn feeder into and out of peripheral engagement with the driven roller so that when the yarn feeder is in peripheral engagement with the driven roller, the driven roller drives the yarn feeder and causes the yarn feeder to feed the yarn in a path from the yarn feeder to the reciprocating needle; anda yarn pullback mechanism for disposition intermediate the yarn feeder and the reciprocating needle, the yarn pullback mechanism mechanically linked to the yarn feeder such that when the actuator moves the yarn feeder out of engagement with the driven roller, the yarn pullback mechanism lengthens the path between the yarn feeder and the reciprocating needle and draws the yarn back from the reciprocating needle, and when the actuator moves the yarn feeder into engagement with the driven roller, the yarn pullback mechanism shortens the path between the yarn feeder and the reciprocating needle.
