ABSTRACT:
A friction false twist apparatus is provided which may be readily threaded-up during operation, and which includes at least three spindles mounted for rotation about fixed axes, with each spindle mounting a plurality of circular discs, and with the discs overlapping at a central location between the spindles. The spindles are concurrently rotated by a common endless drive belt, and a movable yarn deflecting means is provided for selectively moving a yarn from an inoperative laterally spaced position where thread-up may be effected, to an operative path of travel disposed centrally between the spindles and wherein twist is imparted to the yarn by contact with the rotating discs. There is also provided a fixed yarn guide for guiding the yarn from the operative path of travel to a position exteriorly of the area encompassed by the endless drive belt, whereby thread-up may be effected without manually threading the yarn through either the overlapping discs or the endless belt.
