ABSTRACT:
Yarns or filaments from producers packages, having little or no twist therein and mounted upon two-for-one spindle units, are uptwisted, directed to a ply twisting unit where the twisted filaments are plied and downtwisted onto a takeup bobbin of a spindle unit. A selected percentage of the required twist is inserted as the plied, cabled filaments are wound upon the takeup bobbin and the remainder of the required twist inserted as the filaments are unwound from the takeup bobbin and directed to a winder unit. Alternatively, the rate of twist applied to the plied filaments may be increased by driving the traveler ring, thus increasing the life or the speed of the traveler which directs plied filaments to the driven takeup bobbin. Occasionally, when two-for-one spindle units are applying extremely high twist, which slows down the delivery of twisted plied filaments, the driven downtwist takeup spindle unit may employ a super high speed stationary traveler ring. Plied filaments extending between the takeup bobbin and the winder unit may be heat set, if desired.
