Abstract
An apparatus for untwisting a multi-ply yarn over a predetermined portion of the length thereof has an untwisting element provided with two contact surfaces which face one another and between which the multi-ply yarn is guided and whose mutual spacing is greater than the thickness of each of the individual strands forming the multi-ply yarn and smaller or equal to the thickness of the multi-ply yarn, at least along a line transversely of the longitudinal direction of the multi-ply yarn. The contact surfaces are displaced relative to one another in mutually opposing directions transversely of the longitudinal direction of the multi-ply yarn. Torque is then relay transmitted to the multi-ply yarn and leads to the untwisting of the multi-ply yarn. The untwisting operation terminates automatically when the multi-ply yarn is fully untwisted between the two contact surfaces and the two strands are located parallel to one another, since the gap between the two contact surfaces is larger than the diameter of the strands of the yarn and torque is no longer transmitted.
