[Also in Division D1] A reserve winding is formed on a flyer or speed frame after winding the package by winding on to a separate winding collar 9 positioned at the end of the tube. As shown, after flyer 4 has wound a package on bobbin 6, the bobbin is lowered slightly so as to form a reserve winding on collar 9. The package is then doffed so as to break or cut the yarn between the reserve winding and the package, the collar 9 being retained on end piece 12 of the spindle. A new bobbin is placed on the spindle so as to abut the collar 9 and a first layer of yarn is wound on to the bobbin. The collar 9 retains the yarn end during the winding of this first layer and when the bobbin has been traversed to its upper position (Fig. 4) a yarn stripper 41 pushes the reserve winding off collar 9 on to bobbin 6. In an alternative embodiment (Figs. 5 and 6), the yarn stripper is mounted on a separate rail (83) which automatically moves to strip the collar when the bobbin reaches the lower end of its traverse. In this embodiment, the collar is positioned at the lower end of the bobbin. The collar 9 can be fixed to the bobbin shaft or be fixed or releasably secured to the bobbin tube 6 by a tight fitting rubber ring or expansible gripping parts, or it can freely slide on the bobbin shaft under the action of its own weight.
