Abstract

A method and apparatus for imparting false twist to a short staple yarn delivered from a nip of a pair of front drafting rollers before ring spinning. Downstream of the nip the twisted yarn is drawn sequentially across first and second runs of travelling endless belts such that the yarn wraps about a first convex surface of the first run then passes between the first and second runs before wrapping about a second convex surface of the second run. Friction between each of the first and second convex surfaces and the yarn imparts the false twist in a common direction. Maintaining a differential between first and second linear speeds of the first and second runs respectively has been found to reduce yarn defects particularly the nep count.
