Abstract

A yarn traverse apparatus is disclosed for winding a running yarn onto a rotating package, and which includes a first traverse means comprising a guide rail, and a pair of oppositely rotating arms mounted for rotation about closely adjacent parallel, or coaxial axes. A second traverse means is also provided which comprises a grooved roller positioned between the first traverse means and the yarn package being wound. In order to achieve a precise guidance of the yarn onto the package, the first yarn traverse means defines a guide stroke which extends beyond each of the ends of the traverse stroke defined by the grooved roller. In addition, the guide rail and/or the arms include means for guiding the yarn adjacent each of the ends of the guide stroke such that the yarn is free to rapidly rebound a short distance toward the center of the stroke, and is then restrained during movement through a second traverse distance.
