ABSTRACT:
A yarn false twisting apparatus is disclosed which comprises a pair of circular discs which are mounted for rotation about generally parallel spaced apart axes, and such that portions of the surfaces are disposed in opposing face to face relation and define a twisting zone therebetween. In one embodiment, one of the discs is relatively thin and flexible, and such disc is resiliently biased toward the other disc only at the twisting zone. In other embodiments, both discs are relatively inflexible or rigid, and one disc is mounted to its supporting shaft by a gimbal-like interconnection and such disc is resiliently biased toward the other disc only at the twisting zone.
