Abstract
A method for preparing of a workstation of an air-jet spinning machine for the resumption of a yarn spinning process after an interruption includes inserting the yarn end into an inlet opening of the spinning nozzle and transporting the yarn in a reverse motion with aid of the spinning nozzle and a fiber feeding device to a guide channel disposed before the spinning nozzle. A spinning-in yarn end is formed on the yarn in the guide channel. A yarn reserve is formed in an underpressure yarn storage device in from of a yarn winding device. The reverse motion of the yarn to the guide channel is performed by reverse motion of a yarn drawing-off mechanism at the workstation. A workstation configured to perform the method is encompassed by the invention as well.
