ABSTRACT:
In a false twist or friction twist texturing machine of the type wherein a plurality of rotatably mounted spindles each carry a plurality of friction discs which overlap and through which a thread is passed along a zig-zag path between the spindles and over the edges of the friction discs, the friction disc assemblies are improved to the extent that they are formed of a circular base member extending outwardly from an arbor which is then mounted on one of the spindles. Such base members include an inwardly extending peripheral groove and a separate, ring-shaped friction member formed of a resilient material having a relatively high coefficent of friction and formed of such size and shape as to be releasably snap-fit into the groove, whereby when worn out the ring is replaced and the base member reused.
