Abstract
A method and apparatus for producing air entangled yarn from a plurality of yarn ends. A group of individual yarn ends is gathered into a sliver, passed through a yarn tensioner, then wrapped around a pair of rotating rolls. The sliver is carried from the rolls into an air entangling head, and the entangled yarn is removed from the air entangling head and wrapped around the pair of rotating rolls. From the rolls, the entangled yarn is carried through a yarn tensioner and wound up into a standard package. Since the entangling of the individual yarns causes shortening of the sliver, tension is created in the sliver before the air entangling head, and this tension tightens the wrapping around the rotating rolls. The same tension is reflected in the entangled yarn leaving the air entangling head, and this tension tightens the wrapping of the entangled yarn around the rotating rolls. The rotating rolls are rotating at a greater surface speed than the linear speed of the sliver or the entangled yarn, so the tightening causes only a slightly greater feed. Since there is always slip, the amount of feed varies with the tension, so the rate of feed is self adjusting to produce the desired air entangled yarn.
