Abstract
Self-twisted yarn is packaged on a take-up device to prevent loss or modification of the twist previously imparted to the yarn by maintaining the yarn in a substantially rotation-free state as it is guided onto the take-up device. This is accomplished by wrapping the yarn around an elongated guide rod as it is fed to the take-up device under tension or by controlling the tensioned free length of the yarn as it is guided onto the take-up device to preclude rotation of the nodes or points of twist reversal in the yarn.
