Abstract The principles and practice of conventional friction-twisting are first briefly reviewed. A multi-disc friction-twisting device in which yarn is constrained to lie on the friction surfaces at an angle substantially equal to the desired surface-helix twist-angle has significant advantages in its mode of operation. As a consequence of this yarn-path geometry, the resulting motion of the yarn on the friction surfaces can be a substantially slip-free rolling action rather than the skidding action of the traditional friction spindle.
