such a way that the first air blast jet 25 is sloped the most then the air blast jet 26 is sloped the second most and finally the air blast jet 27 is sloped the least to carry the transportation of the separated thread to the suck in area of the suction bell 21 this arrangement is particularly advantageous for an optimally secure safe transfer of the broken thread to the suction bell 21 intermittent drive of the spindle 17 and intermittent blowing will serve to insure that large lengths of thread are quickly separated from the thread winding body 15 which otherwise could produce the danger that the separated thread could get caught somewhere and thus would not get into the suction bell the preferredly provided intermittent blowing out of the air blast which advantageously may take place in equal phase or in some cases from time to time in counter phase with the intermittent drive of the spindle 17 improves the separation effect and the sure blowing of the separated thread to the action area of the suction bell 21 in this preferred embodiment the cradle 10 is below the ring rail 30 of the pertinent side of the machine and is moved along with the ring rail 30 for example by means of a driver 34 resting on the ring rail with this arrangement it is preferably provided that the blowing out.
