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.
In an apparatus for false twisting threads by means of friction discs which comprises three rotatably mounted spindles, each provided with at least one friction disc, the spindles lying at the corners of an equilateral triangle in plan view and being arranged at a fixed mutual spacing and driven in the same direction of rotation, the friction discs on each spindle overlapping the discs on the two other spindles and means for passing the thread which is to be provided with a false twist through at least one thread guide, a thread guide which is movable between a diverted position in which the thread runs clear of the friction discs and a false-twisting position in which it runs between the discs in a zig-zag path.
In a false-twisting apparatus comprising spindles having overlapping friction discs disposed where a thread passing therebetween will pass over the edges thereof and means for guiding a thread between the said discs and into a balloon preventer, a thread feeding means for moving a thread into and out of a position where it is false twisted comprising a thread guide member, an arm supporting said guide member and a rotatable shaft supporting said arm with the guide member above the top friction disc, said rotatable shaft being rotatable from a position where the guide member is disposed above the gap between the edges of the friction discs to where the guide member is disposed outside said friction discs, and a thread slide member supported between a pair of longitudinally spaced friction discs and having opposite arcuate shaped edges over which the thread slides as the thread guide member moves the thread into and out of said gap.
