A method is provided for operating an air spinning machine with a multiple number of spinning units, whereas each spinning unit has a spinning nozzle with an internal vortex chamber. The spinning nozzle is fed a fiber composite during the operation of the spinning unit. The spinning nozzle has a multiple number of air nozzles leading into the vortex chamber through which compressed air streams into the vortex chamber in order to generate a vortex air flow within the vortex chamber. The fiber composite receives a twist with the assistance of the vortex air flow within the vortex chamber such that a yarn is formed from the fiber composite. The air spinning machine features an additive supply, whereby an additive is at least temporarily fed a part of the spinning units. A liquid additive is used, whereas the additive is degassed prior to leaving the additive supply. In addition, an air spinning machine with a degassing device is described.

A spinning point of a spinning machine includes a spinning unit, a drawing-off device for the yarn downstream of the spinning unit and a yarn storage downstream of the drawing-off device for the intermediate storage of a section of yarn. The yarn storage has a sensor system for monitoring the filling level of the yarn storage (). The spinning point includes a winding device for the yarn downstream of the yarn storage, along with a return unit, with the assistance of which an end of the yarn found within the yarn storage after a yarn break is returned into the area of the spinning point. The winding device () is stopped in the case of a yarn break in such a manner that, after the stop, an end section of the yarn remains within the yarn storage (). Subsequent to this, a part of the yarn is separated with the assistance of a yarn separation unit internal to the spinning point, and that the end of the yarn that newly arises in this manner is returned with the assistance of the return unit internal to the spinning point into the area of the spinning point, and that a piecing process is then carried out.
