ABSTRACT:
In the friction spinning of yarns, staple fibres are supplied to a yarn formation zone in which the yarns end is rotated by frictional contact with at least one twisting element. In the yarn form zone, a jet of air is applied to the yarn or forming yarn by nozzle to increase the frictional forces between the yarn or forming yarn and the twisting elements. The formed yarn is continuously removed from the yarn formation zone.
