Abstract: In a process for manufacturing a singles ring yarn, firstly a first twist is supplied to a strand of traveling drafted fibers at a false twist device for producing a preliminary singles yarn. The false twist device rotates at a first speed for twisting the fibers. Immediately after the first twisting step, a joint twist of a second twist in the same direction as the first twist and a third twist in a reversed direction is supplied to the preliminary yarn for producing a final singles ring yarn. The second twist is produced by a rotatable take-up package onto which the final singles yarn is drawn. The reversed twist results in correspondence to the first twist, and the take-up package rotates at a second speed. The final singles yarn is then drawn onto the take-up package. Furthermore, a ratio of the first speed to the second speed is controlled for controlling the amount of a residual torque in the final singles ring yarn.
