A textile machine and associated method are provided for operating the textile machine that includes a plurality of workstations, wherein each workstation includes at least one stepper motor configured to drive an element at the workstation. The method includes measuring a load variable, for example a load angle, of the stepper motor and detecting an approach of the element to an end position based on changes to the load variable.

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 An interior draw-off channel in the spinneret has a longitudinal axis by means of which the yarn is withdrawn from the eddy chamber.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.

A process for manufacturing a yarn includes twisting the yarn in a first direction for a predefined number of twists. The method also includes, after the predefined number of twists, twisting the yarn in a second direction for a predefined number of twists, the predefined number of twists for the second yarn is same as the predefined number of twists for the first yarn. The twisting of the yarn in the second direction creates an air bed within the yarn's fibers.

A textile machine having a plurality of spinning devices, more particularly air-jet spinning devices, which spinning devices have an inlet opening for a fiber band to be spun, and to a spinning hood for a spinning device of a textile machine. In order to provide a textile machine comprising a plurality of spinning devices, which have an inlet opening for a fiber band to be spun and in the case of which the feeding of contaminants into the inlet opening is prevented as much as possible, there is provision for a spinning hood to be provided, which is designed in such a way that the spinning hood separates a spinning space around an inlet opening of the spinning device from the surroundings.
