Drum 18, which serves the langentialantrleb of the cheese 17 and at the same time the thread continuously back and forth in the axial Riohtung so that it is wound into the cheese 17. The slotted drum 16 is driven by a motor 19 having a constant speed via a clutch 20 which can be engaged and disengaged. The clutch is controlled automatically by means of an electrical Sohalter 21, which is closed when the filling state of the buffer 15 falls below a certain setpoint value and in this state the clutch intermittently disengages and engages in order to lower the speed of the slotted drum 18 in the geItlieheα means so that Then the speed at which the thread is withdrawn from the intermediate store 15 is slower on average over time than the feed speed at which the thread enters the intermediate store 15 as a result of its Yorsohubee caused by the orphan couple 13, 14. As a result, the buffer 15 is filled up again. When the target value of the FUllzuetandes is exceeded again, the switch 21 opens, whereby the intermittent operation of the clutch 20 is ended and the clutch remains continuously engaged. The speed of the slotted drum 18, which then remains constant, is such that the thread is withdrawn from the intermediate store 15 at a speed which is somewhat greater than the torso stroke speed caused by the pair of rollers 13t 14. As a result, the filling level of the intermediate storage device slowly decreases again, so that when the FUU level falls below the setpoint, the so holder 21 is closed again and the intermittent operation of the clutch 20 is switched on again.

Each thread area of the thread running up on the roller device 40 traverses all the windings, the thread is guided slip-free by the rollers 43 set in rotation by it to the drainage point 46, the local position of the Drain point 46 remains constant. In contrast, dlo is angled and the axial position of the run-up point 47 through the respective Determines and changes the spatial position of the eyelet 58 of the thread guide element 36, which is opposite the roller device 40 sioh with the rotation of the lead screw 32. When the lead screw 32 rotates in the direction of arrow D, the thread is unwound from the roller device 40, the eyelet 38 with respect to Figure 2 moves to the right in a helical path. With opposite rotation (arrow E) of the threaded spindle 32 the thread is wound onto the roller device 40 in a helical path · If, for example, a thread breakage enters the spinning turbine and the thread is conveyed back into the spinning turbine 12 in the direction of arrow B (Figure 1), the angle device 32, 36 becomes so by the pulling of the thread rotated so that the thread is unwound from the roller device 40 without thereby the withdrawal of the thread from the roller device is influenced in the direction (arrow F) towards the slit drum.

The torque device formed by the cord drum 33 with cord 34 and weight 35 causes a constant uniformity Tension of the thread in the area between the eyelet 38 and the point 47 and thereby also causes the winding, The energy for this is provided by the downward movement of the weight 35 during the winding up.
