Abstract
In a method and machine for winding on a continuously fed yarn to form bobbins alternately onto respective tubes on winding spindles on a revolver member, the yarn is guided via a stationary head yarn guide, a traversing device and a contact roller to a first yarn guide to position the yarn at the catch region of the empty tube. A second yarn guide for the yarn end running onto the full bobbin is mounted on a pivotal arm to pivot into the gap between the bobbin and the empty tube. The first yarn guide is arranged on the pivotal arm. The traversing device, the contact roller, the winding spindle and the yarn guides are on one side of the yarn. After pivotal movement of the pivotal arm into the gap the yarn is guided free from the surface of the empty tube and also comes free from the traversing device. During return movement of the pivotal arm the yarn is applied to the catch region of the empty tube with an increase in the wrapping angle.
