ABSTRACT:
A method for winding a yarn reserve a tube of a bobbin before a yarn package is wound includes initially applying a piece of yarn on an end of a tube of a bobbin while leaving a free yarn end. The piece of yarn is covered and fixed in place with a small number of yarn windings of a yarn reserve. The free yarn end is severed on the tube between the yarn reserve and the tube end while the bobbin is rotating. An apparatus for winding a yarn reserve on a tube of a bobbin before a yarn package is wound includes a holder for a bobbin tube. A yarn transferring device delivers a yarn to the tube. A drive drives the tube while initially applying a piece of yarn on an end of the tube and leaving a free yarn end. A yarn guide lays the yarn on the tube and covers and fixes the piece of yarn in place with a small number of yarn windings of a yarn reserve. A yarn cutter trips a severing process by being fed toward the rotating tube and severs the free end of the yarn on the tube between the yarn reserve and the tube end.
