1. 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; and
a 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.

Abstract
Apparatus for feeding yarn from a yam supply to a reciprocating needle of a multi-color pattern carpet tufting apparatus comprises a yarn pullback mechanism mechanically linked to a yarn feeder such that when the yarn feeder moves out of engagement with a driven roller, the yarn pullback mechanism draws the yarn back from the reciprocating needle. When the yarn feeder moves back into engagement with the driven roller, the yarn pullback mechanism shortens the path between the yarn feeder and the reciprocating needle.

11. An apparatus for producing patterned tufted fabric comprising:
-
a tufting frame;
a yarn applicator comprising a reciprocable needle for penetrating a backing at a stationary yarn applying region and implanting a yarn therein;
a backing transport system mounted to the tufting frame for moving the backing past the stationary yarn applying region and moving the backing transversely relative to the stationary yarn applying region so that the yarn applicator implants the yarn in a transverse row upon selective successive penetrations by said needle; and
a yarn feed mechanism for feeding the yarn from a yarn supply to the 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; and
a yarn pullback mechanism disposed 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.- View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
