drive 28 fig4 shows the ring spinning frame 1 with the rewinding device 12 which is movable the spindles 6 are driven by individual motor drives 27 whilst the ring rail 10 34 with the ring traveller 10 is moved up and down by the main drive of ring spinning frame 1 it is also possible to use an individual ring carrier drive the difference of the construction of fig4 as compared with fig3 is that the winding off of the yarn carrier 7 takes place in the spinning station 5 yarn guidance and feeding shown in simplified diagrammatic form is performed by using a guide pulley 40 here again the yarn end is caught by the thread seeking nozzle and transferred to the thread joining device 17 the arrangement shown in fig4 will probably only be used in special cases because during the winding off of the yarn carrier 7 the spinning station 5 cannot be put into operation however it is advantageous that the motor drive 27 can be used for speeding up the running off of the yarn independently on whether a full or a partly full yarn carrier 7 is removed from the spinning station 5 this is followed by the initial spinning of the thread by applying the yarn carrier 7 as shown in fig5 as seen from fig5 a starter yarn 31 is removed from a reserve or store bobbin 30 and placed on an empty yarn carrier 7 39 e g by clamping or winding in this case the empty yarn carrier 7 39 has a yarn clamp 33 the starter yarn 31 is threaded on ring traveller 10 39 by a traveller threader 32 and an air nozzle 32 39.
