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. One disc is mounted to its supporting shaft by means of an elastomeric body member, which permits the disc to resiliently incline with respect to the axis of the shaft. A pressure applying member acts upon the back side of such disc to resiliently bias the same toward the other disc at the twisting zone.
