ABSTRACT:
A core wrap system is provided in which a core strand and wrap strands spaced from said core strand on each side of said core strand are passed from the nip of a pair of rollers to a stationary support surface that is outwardly, downwardly curved, and which includes an open channel therein which is outwardly, downwardly curved along the surface; wherein the core strand is passed through the channel from the nip; wherein the wrap rovings are passed from the nip to converge upon and wrap around the core strand in the channel to form wrapped yarn in the channel; and wherein wrapped yarn then is passed through a ring traveler to a wind-up spindle.
