摘要： A method and apparatus for producing randomly variegated multiple strand wrapped yarn in twisting together two or more yarns (16) at a plurality of yarn twisting stations. At each station a pneumatic twisting head (26) is disposed in which randomly turbulent air currents are created in a chamber (57) in the twisting head (26) by compressed air flowing into the chamber in the twisting head by compressed air flowing into the chamber (57) from a manifold (24) through bores (50) in the twisting head (26), thereby randomly twisting together two or more yarns (16) in the chamber (57). The yarns (16) which have been twisted together are wrapped with a binder yarn (102) and then taken up over a plurality of traversing drums (30) commonly mounted on a shaft (34) which is driven by alternating electric current motor (36) controlled by a control device (40) which operates to start and restart the motor (36) on a predetermined cycle including a variation of the electrical input sufficient to result in randomly unpredictable inertia resistance of the traversing drums (30) to rotational speed variation, thereby creating randomly unpredictable take-up of the yarns to produce non-uniform random twist in the yarns. The yarn produced has various lengths of opposite twist with varying degrees of twist and sections of no twist and section of varying wrap, and the fabric produced with the yarn is randomly variegated with no repeating pattern.
