The invention relates to a spinning unit of an air spinning machine with a spinning nozzle (1), which serves the purpose of producing a yarn (2) from a fiber composite (3) fed to the spinning nozzle (1), whereas the spinning nozzle (1) features an inlet (4) for the fiber composite (3), an internal vortex chamber (5), a yarn formation element (6) protruding into the vortex chamber (5) along with an outlet (7) for the yarn (2) produced inside the vortex chamber (5). In accordance with the invention, it is proposed that the spinning unit is allocated with an additive supply (8), which is designed to supply the spinning unit with an additive (9), whereas the additive supply (8) includes at least one valve (10), with the assistance of which the volume flow and/or mass flow of the additive (9) is adjustable, and whereas the valve (10), during the operation of the same, opens and closes at least once per second, such that the additive (9) fed to the valve (10) leaves the valve (10) in a pulse-like manner. In addition, a method for operating an air spinning machine is proposed. |
