ABSTRACT:
An open-end rotor spinning apparatus is provided which includes at least one spinning unit having yarn deflecting elements downstream from a yarn withdrawal duct. The yarn deflecting elements deflect yarn from the yarn withdrawal duct in a yarn spinning path. The yarn deflecting elements include at least one false-twisting edge. Yarn returning elements are provided for returning a yarn end to the yarn withdrawal duct past the yarn deflecting elements in a piecing path having a deflection less than the yarn spinning path deflection.
