ABSTRACT:
A stable plied yarn is produced by false-twisting two or more singles yarn strands with false-twist 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 is collected and can be tufted into carpet. The pressure of the fluid (air) supplied to the false-twist jets is varied to product varying amounts of twist in the singles strands which results in a range of twist amounts in the yarn plied therefrom, thereby avoiding streak effects in products made from the yarn.
