Abstract
A stable plied yarn is produced by false-twisting two or more singles yarn strands with jets and passing the strands around a yarn wheel whereon the nodes are joined. The strands leave the wheel and ply together. The plied yarn passes through a reversible jet aspirator which assists the plying and propels the yarn through a coiled tube. The aspirator is supplied with air or with steam to bulk the yarn. After leaving the tube, the yarn can be caused to strike a solid surface to further enhance bulking. A press roll at the yarn wheel aids in defining a twist trap.
