ABSTRACT:
This invention is directed to an improved apparatus in which a fluid jet texturing device is used to produce a composite novelty yarn having slubs of selectively varied size distributed with selectively varied spacing along the linear length of the yarn. The apparatus includes at least two feed rolls to serve to feed yarn to the texturing jet, one of said rolls being operable to feed yarn at a higher speed than the other roll or rolls. An actuator arm is provided having an idler roll at one end. The first yarn is directed into contact with a slower feed roll while a second yarn is directed into contact with the idler roll. The actuator arm is selectively moved so as to first press the second yarn against the relatively fast roll and then press this yarn into contact with a slower feed roll to thereby vary the speed at which the second yarn is fed into the texturing jet.
