Abstract
An air spinning machine for producing a yarn from a fiber structure includes a spinneret with an internal eddy chamber. A spindle in the spinneret has an intake opening and extends into the eddy chamber. An annular gap is formed between an outside surface of the spindle and an inside wall of the eddy chamber. Air jets in the spinneret introduce air into the eddy chamber to impart twist to the fiber structure at the intake opening. An interior draw-off channel in the spinneret has a longitudinal axis by means of which the yarn is withdrawn from the eddy chamber. The air jets are aligned in a direction relative to a front side of the spindle around the intake opening so that some of the air introduced via the air jets during a spinning operation enters the annular gap and a remainder of the air enters the draw-off channel.
