    Abstract: A winding machine incorporating yarn traversing mechanism having a pair of oppositely moving belt spans, each provided with yarn engaging guides for moving the yarn along a traversal path in a controlled manner to wind a package of yarn, the yarn being transferred from one guide to another at each end of the path adjacent each package end. The traversal path of each of the spans is regulated so that the oppositely moving spans run parallel to the axis of the package in the zone corresponding to the axial midsection of the package. In the zones corresponding to the end sections of the package the oppositely moving belt spans run in paths diverging from said parallel paths. Stabilizing pulleys are provided to track the oppositely moving belt spans and thereby preclude vibrations being introduced into the yarn during its traversal.

    Abstract: A winding machine incorporating yarn-traversing mechanism having a pair of oppositely moving belt spans, each provided with yarnengaging guides or fingers operable in a yarn-traversing zone to move the yarn along a path in a controlled manner to wind a package of yarn, the yarn being transferred at each end of the package from an active finger traversing the yarn in one direction axially of the package to an oppositely moving finger. In the yarn-traversing zone each of the belt spans moves generally parallel to the axis of the package being wound. Means are provided for causing the yarn to slide gradually outwardly along the finger which is traversing it as the yarn progresses axially across the package. Said means is so configured that the yarn is caused to disengage from its finger at a locus corresponding to an end of said package whereupon the yarn is disposed for immediate engagement by an oppositely moving finger which traverses the yarn in the opposite direction. Reciprocation of the yarn axially to and fro of the package is thus achieved.
