Abstract
The application relates to a device for air spinning, i.e., for the manufacture of a spun yarn from a sliver. The device contains in particular a fiber guide element, a fiber conveying channel, and an eddy chamber housing attached to the fiber guide element. The eddy chamber housing contains in its turn a spindle with a yarn guide channel arranged at a distance interval from the fiber guide element. In addition, the eddy chamber housing contains a fluid device with at least one jet nozzle for the production of an eddy current about an inlet aperture mouth of the yarn guide channel. The fiber conveying channel exhibits a tunnel cladding, which is dimensioned in such a way that at the end of the fiber conveying channel a step to the eddy chamber housing is formed.
