Abstract
The invention relates to high-speed yarn traverse winding apparatus, method and product. Circling thrust members are provided to intercept a yarn being reciprocably traversed and forwarded to a bobbin in a winding zone to acceleratively control the reversal displacement of the yarn on the bobbin. A yarn package having a high resolution of symmetry is produced, the package being characterized in that the majority of the reversal curves of the helical windings are comprised essentially of camber curves generated substantially to a point of projected intersection of the diagonal linear extensions of the helical windings.
