Abstract: An apparatus having three spindles carrying overlapping friction discs disposed with their longitudinal axis forming in plan view the corners of an equilateral triangle is provided with a centrally disposed fourth spindle carrying a means for simultaneously and equally adjusting the positions of all three spindles with respect to the track of the thread to be false twisted.

Abstract: A false twisting apparatus having three spindles supporting over-lapping friction discs and having a means for feeding a thread between the friction discs where it will be false twisted and into a balloon preventing member is provided with an improved means for threading the apparatus by moving a thread into position between the friction disc comprising a thread guide member on an arm supported by a rotatable shaft with the guide member above the friction disc, the rotatable shaft being rotatable from a position where the guide member is disposed above the gap between the edges of the friction disc to where the guide member is disposed outside the friction disc and a thread slide member supported on a shaft and projecting inwardly between longitudially spaced friction discs, the slide member having arcuate shaped edges over which the thread can slide as it is moved by the thread guide member into or out of the gap between the friction members.
