Abstract
A core/wrap yarn is formed on a conventional ring-spinning yarn system by including a gripper nip immediately downstream from and closely adjacent to the front roller nip of the system; feeding a core strand and at least one wrap stand on each side of the core strand from the front roller nip to the gripper nip, wherein the wrap strands are spaced from the core strand at the front roller nip and converge with the core strand in the gripper nip to wrap around the core strand in the gripper nip so as to form wrapped yarn which then is passed through a ring traveler on to the wind-up system.
