ABSTRACT:
Untextured yarn is drawn from a producer's package, threaded through apparatus comprising a tension leveling device, an electric heater and a false twist device and, having been textured thereby, is wound on yarn take-up means. The false twist device comprises a staggered arrangement of friction discs and a plurality of hold down arms. The yarn passes over the rims of the several discs in contact therewith and is twisted as the discs rotate in the same direction at the same rate of speed. The arms function to effectively limit movement of the yarn back and forth circumferentially of the discs, as a consequence of which the yarn is twisted in place or very nearly in place.
