Abstract
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.
