connection between the female thread 50 of the rotor 46 and the male thread 52 of the yarn guide 18 which is secured against rotation by a torsion preventer 58 an axial shifting of the yarn guide 18 occurs the torsion preventer 58 can as indicated in fig2 comprise a longitudinal groove 60 in the region of the male thread 52 of the yarn guide 18 along with a securing element 62 the securing element 62 is fixed against relative rotation on the stator 44 of the stepping motor 40 and thus engages in the longitudinal groove 60 because the drive device 38 virtually encompasses the yarn guide 18 only an extremely small amount of space is needed to accommodate the drive device 38 moreover in turn the rotor 46 is effectively operationally connected directly to the yarn guide 18 as a result it is unnecessary to provide intermediate transmission members the driving force can thus be initiated directly and precisely at the same time the drive device 38 takes on the function of the yarn guide 18 which is supported in quasi floating fashion by the drive device 38 so that there is no need to provide further bearings or the like the centrifugal spinning device 12 is also provided with a covering 54 which is braced on one side on the drive device 38 and on the other on the upper end of the yarn guide 18 the covering 54 has a substantially flexible cylindrical sheath 56 for example in the form of.
