Abstract:
A method for depositing a yarn end on a bobbin wound on a tube in a defined manner during winding of yarn on the bobbin at a workstation of a spinning and winding machine includes terminating spinning production of the yarn at the workstation to create a yarn end. The yarn end is then prepared with working devices at the workstation, including rotating the bobbin in a direction opposite to a winding direction during production of the yarn. A yarn reserve is formed, and the yarn end is then deposited in a defined manner on the tube outside of the profile of a standard yarn package.
