File No. 10 2005 036 485.3 I, ASTRID TERRY, Translator of 11 Bounds Oaks Way, Tunbridge Wells, Kent, TN4 OUB, confirm that I am familiar with the English and German languages, and that to the best of my knowledge and belief the accompanying document which has been prepared by me, is a true translation of the authentic text of the Certificate of Priority Document on the filing of the Patent Application File No. 10 2005 036 485.3 dated 3rd August 2005. Signed this 8th day of June 2006 Description: Open end rotor spinning machine The invention relates to an open end rotor spinning machine according to the preamble of claim 1. Open end rotor spinning machines of this type, as known and described, for example, in DE 198 36 065 Al, have a plurality of similar workstations arranged next to one another in a row, on which a fibre band preferably presented in a spinning can is spun to form a thread and then wound to form a cross-wound bobbin. The individual workstations, in each case, for this purpose have a spinning device and a winding device, both the working members of the spinning device and the working members of the winding device generally being loaded via drive means along the length of the machine. In other words, arranged in the region of the spinning devices, are tangential belts to drive the spinning rotors and the fibre band opening rollers as well as a drive shaft along the length of the machine for loading the fibre band draw-in cylinder. The drive of the bobbin drive roller arranged in the region of the winding devices is also implemented via a drive shaft along the length of the machine. A thread guide rod going back and forth is also present, which is loaded by a traversing gearing arranged at the end of the machine, and on which the thread guides are fixed. Furthermore, thread take-off mechanisms are present, the driven take-off rollers of which are a component of a continuous drive shaft. The workstations of such open end rotor spinning machines are attended to by service units, which patrol and automatically intervene, for example, along the workstations when a failure, for example, a thread break, has occurred at one of the workstations. In a case such as this, the service unit runs to the relevant workstation, is locked there and with a pivotably mounted suction nozzle, which can be vacuum-loaded, seeks the thread which has run 2 onto the cross-wound bobbin after a thread break. Apart from the suction nozzle, such service units also have a series of further thread handling elements, which allow the thread taken up by the suction nozzle, after a corresponding preparation in the open end rotor spinning device of the relevant workstation, to be repieced on a fibre ring circulating there with the spinning rotor. The individual thread handling elements of the service unit, including the suction nozzle, are preferably driven by an electric motor which drives a cam disc pack which is connected via special lever rods to the thread handling elements. Service units of this type, which are described in relative detail, for example in DE 198 27 605 Al, are relatively complicated, however, with respect to their design structure and therefore relatively cost-intensive. Rotor spinning machines, which were still driven without such moveable service units, are also known from the past from DE-OS 22 03 198 or DE-OS 25 34 816. In the region of the thread take-off tubes of their spinning devices; these open end rotor spinning machines, in each case, have a piecing aid, which makes it possible to shorten a thread retrieved from a cross-wound bobbin to a specific length, to prepare it, convey it back to the rotor groove of a spinning rotor rotating in a spinning housing which can be loaded with a vacuum and to piece it there on a circulating fibre ring. However, it is disadvantageous in these mechanisms that piecing a new thread on the fibre ring circulating in the rotor groove takes place in a substantially uncontrolled manner. In other words, in these known mechanisms, there is neither an exact matching of the thread feed into the spinning rotor nor an exact time matching of the thread take-off to the speed of the spinning rotor and this leads to the fact that the piecers generated with these known mechanisms do not at all correspond to current quality standards. 3 Furthermore, open end rotor spinning devices are known which have various single drives in the region of their workstations. Open end rotor spinning devices are described, for example in DE 43 09 947 Al, in which the fibre band draw-in cylinder and/or the fibre band opening roller are driven, in each case, via a single drive. An open end spinning machine is also known from DE 100 62 096 A*l, in which various single drives are arranged, in each case, in the region of the workstations. The workstations of this rotor spinning machine, for example, have an open end rotor spinning device with a single motor-driven fibre band draw-in cylinder, a single motor-driven thread take-off mechanism and a single drive for the bobbin drive roller. Furthermore, an open end rotor spinning machine, the workstations of which are conFigured such that they can automatically eliminate failures, in particular thread breaks, is described in EP 1 283 288 A2. The very substantially self-sufficient workstations of this known open end rotor spinning machine, apart from the spinning station's own suction nozzle, also inter alia have single drives for the bobbin drive roller and the thread take-off mechanism. The workstations also, in each case, have a piecing aid device which is arranged in the region of the open end rotor spinning device and in which the thread provided by the suction nozzle is prepared for repiecing. Preceding from the above prior art, the invention is based on the object of providing an economical open end rotor spinning machine, which is conFigured such that the workstations can be restarted without problems after a failure, without a special service unit being necessary for this, wherein the quality of the piecer being produced should correspond to current high quality standards. This object is achieved according to the invention by a device as described in claim 1. 4 Advantageous conFigurations of the invention are the subject of the sub-claims. The embodiment of an open end rotor spinning machine described in claim 1, has the advantage, in particular, that it is economical to implement, on the one hand, and, on the other hand, allows piecers to be produced, which correspond to current high quality standards. In other words, piecers produced after a failure, for example a thread break, are comparable with piecers such as are produced by automatically operating service units with regard to their appearance and their strength. The number of unrecognised "out-of-standard" piecers can also be significantly reduced with the mechanism according to the invention, as such piecers, when the thread is taken off from the spinning device, already lead to a thread break, in particular owing to the high rotor speed. In other words, on average, the quality of the piecers produced with the mechanism according to the invention is better than piecers which are produced with a service unit. Overall, open end rotor spinning machines with the features described in claim 1 are distinguished by a very favourable price/performance ratio. As described in claim 2, in an advantageous embodiment, a stationary mechanism is arranged in the region of the open end rotor spinning device and allows a thread manually retrieved from the cross-wound bobbin to be cut to length precisely in a simple manner. The thread that has been cut to length can then immediately be properly prepared for refeeding into the open end rotor spinning device by a manual thread preparation apparatus which the operator preferably carries on him. In other words, the thread end is made as far as possible twist-free. The manual thread preparation has the advantage that the operator can visually check the result of his preparation and optionally correct it. In this manner, it can be ensured that only properly prepared thread ends are conveyed back into the spinning device for repiecing and this has a very positive affect on the quality of the piecers. 5 It is advantageous, as described in claim 3, that the control mechanism of the workstation is configured and connected to the thread take-off mechanism in such a way that, on manual activation of the control mechanism, feeding of fibres into the spinning rotor is immediately started and in addition the return of the thread end that has been cut to length in to the spinning rotor rotating at operating speed is initiated in a manner so as to be precise in terms of time and length. The control mechanism in this case ensures an extremely precise thread return feed, in other words, the prepared thread is conveyed back in to the spinning rotor according to instructions and placed on the fibre ring rotating there. As described in claim 4 and 5, the spinning rotor is either rotated by a tangential belt along the length of the machine or by a single drive. The fibre band opening roller can either, as described in claim 6, be driven by a tangential belt along the length of the machine or, as described in claim 7, by a single drive, which is preferably conFigured in a case such as this as a so-called external rotor drive. The embodiment described in claims 4 and 6 with a tangential belt drive is an economical and proven type of drive, in each case, while the variant described in claims 5 and 7 with a single drive respectively offers the advantage that a drive of this type can be adapted individually at any time to the respective work situation if necessary. According to claim 8, it is also provided in an advantageous embodiment that a drive mechanism to lift the cross-wound bobbin from the bobbin drive roller is provided in the region of the creel. The drive mechanism is preferably configured here as a sliding piston gearing, which loads the creel, in which the cross-wound bobbin is held and which can be activated in a defined manner via an electromagnetic valve by the control mechanism. In other words, the cross-wound bobbin can be placed in a targeted manner on the rotating bobbin drive roller during the piecing 6 process and after the repiecing of the thread can rapidly be accelerated at least to a speed in which the peripheral speed of the cross-wound bobbin corresponds to the thread take-off speed. As the acceleration of the cross-wound bobbin, in particular in the case of large bobbins, initially remains slightly behind the thread take-off, the excess thread thus occurring is initially compensated by means of a storage mechanism, which operates at this time as a passing thread store. In other words, a thread loop is initially formed in a pneumatically loaded thread store (claim 10) and is slowly released again in the course of the spinning process. The pneumatic thread store thus also takes up the thread length, which is required at the beginning of the piecing process in conjunction with the thread refeeding. As explained in claim 9, the creel also has a braking mechanism via which the cross-wound bobbin can be fixed to prevent rotation if necessary. In other words, after the thread has been manually retrieved, the braking device prevents further thread material impairing the piecing process from being unwound inadvertantly from the cross-wound bobbin, in addition to the thread length required in conjunction with the forming of the thread length for the piecing process. Further details of the invention can be inferred with the aid of the embodiment described hereinafter in the drawings, in which: Fig. 1 shows a side view of a first embodiment of a workstation of an open end rotor spinning machine according to the invention, Fig. 2 schematically shows the activation of the single drives of a workstation in a further embodiment of the invention, 7 Fig. 3 shows a manual thread preparation apparatus for treating the thread end of the thread that has been cut to length and retrieved by the operators from the cross-wound bobbin. Fig. 1 shows one half of a semi-automatic open end rotor spinning machine 1 according to the invention. Spinning machines of this type have a plurality of workstations 2, which are equipped, in each case, with a spinning device 3 and a winding mechanism 33. In the spinning devices 3, the fibre band 34 presented in spinning cans 28 is spun, in each case, to form a thread 30, which is wound on the winding mechanism 33 to form a cross-wound bobbin 22. The winding mechanisms 33 have, as known per se, a creel 21, in each case, for rotatably holding the tube of a cross-wound bobbin 22, a bobbin drive roller 23, a thread traversing mechanism 26 and a mechanism 7 for lifting the cross-wound bobbin 22 from the bobbin drive roller 23. The mechanism 7 is configured for example as a sliding piston gearing, which is connected to an excess pressure source (not shown) via a pneumatic line 24, into which an electromagnetic valve 17 is inserted. Furthermore, a braking mechanism 50, by means of which free rotation of the cross-wound bobbin 22 lifted from the bobbin drive roller 23 can be prevented, if necessary, is arranged on the creel 21. In the present embodiment, the bobbin drive roller 23 is driven as a group drive. In other words, a drive shaft along the length of the machine is provided, on which the individual bobbin drive rollers 23 are fixed. In an alternative embodiment, however, a single motor drive of the bobbin drive roller 23 is also possible. In a case such as this, the drive of the bobbin drive roller is connected via a corresponding control line to the spinning station's own control mechanism 9. 8 A thread lifting mechanism (not shown) , known per se, can also be installed in the region of the winding mechanism 33. A thread lifting mechanism of this type prevents the thread being able to be grasped inadvertently by the traversing thread traversing mechanism 26 during the piecing process. In other words, the thread lifting mechanism configured as a foldable plate, for example, initially holds the thread during the actual piecing process at a spacing above the thread traversing mechanism 2 6 going back and forth. The spinning device 3 substantially has, as known, a spinning rotor 4, a thread band opening roller 12 and a thread band draw-in cylinder 14. According to the embodiment of Fig. 1, the spinning rotor 4 is mounted in a support disc bearing 5, for example, and is driven via a tangential belt 6 along the length of the machine. To detect the speed of the spinning rotor 4, a sensor mechanism 8 may also be provided, which is then connected to the control device 9 via 3. signal line 40. The fibre band opening roller 12 is preferably also loaded via a tangential belt 13 along the length of the machine, while the fibre band draw-in cylinder 14 is driven by a single motor via a drive 15. The drive of the fibre band draw-in cylinder 14, for example a stepping motor 15 is also connected to the control mechanism 9 via a control line 16. Furthermore, the workstations 2 each have a thread take-off mechanism 18, the drive 19 of which is connected via a control line 20 to the control mechanism 9. Viewed in the thread running direction, a thread storage mechanism 37, preferably a pneumatically loadable storage nozzle, is provided downstream from the thread take-off mechanism 18. The storage nozzle 37 is connected, in this case, via a pneumatic line 38 to a vacuum source (not shown). 9 Finally, a stationary device 10 is arranged in the region of the spinning device 3 and allows defined cutting to length of a thread retrieved manually from the cross-wound bobbin 22, the thread end of which can then be treated by the operators by the thread preparation mechanism 25 shown in Fig. 3. This thread preparation mechanism 25 for manually preparing the thread substantially consists of a handle 36 and a thread handling region 35 for processing the thread end. As indicated in Fig. 1, the control mechanism 9 which controls the drive of the mechanism 7 for lifting the cross-wound bobbin, the drive 16 of the thread take-off mechanism 18 and the drive 15 of the fibre band draw-in cylinder 14, is connected via a signal line 29 to a switching element 27. In other words, the control mechanism 9 can be activated manually via the switching element 27. In an alternative embodiment, which is shown in Fig. 2, the spinning rotor 4 is not supported in a support disc bearing 5, but in a magnetic bearing, indicated only schematically. The spinning rotor 4, in a case such as this, is preferably loaded by a single drive 31. The spinning rotor drive 31 is connected, in this case, via a control line 45 to the control mechanism 9. As also shown in the embodiment according to Fig. 2, the fibre band opening roller 12 can also be driven by a single motor. In other words, arranged inside the clothing ring of the opening roller, is an external rotor drive 59, for example, which is also connected to the control mechanism 9 via a control line 32. Operation of the open end rotor spinning machine according to the invention: During the regular spinning process, the thread 30 produced in the spinning device 3 is taken off by the thread take-off mechanism 18 and wound on the winding device 33 to form a cross-wound bobbin 22. 10 The cross-wound bobbin 22, which is rotatably mounted between the arms of a creel 21, rests, in this case, with its surface on the bobbin drive roller 23 and is driven by it in the winding direction via frictional engagement. At the same time, the thread 30 running onto the bobbin is transferred by means of the thread traversing mechanism 26 in such a way that it runs in crossing layers on to the lateral surface of the cross-wound bobbin 22. If there is a failure, for example a thread break, at one of the workstations 2 of the open end rotor spinning machine 1, which may preferably be detected by a stop motion (not shown), the control mechanism 9 ensures that the relevant workstation 2 is stopped. In other words, the drive 15 of the fibre band draw-in cylinder 14 is firstly switched off in the region of the spinning device 3 and further' fibre supply to the spinning rotor 4 is stopped. Simultaneously, the drive 19 of the thread take-off mechanism 18 is simultaneously switched off and the cross-wound bobbin 22 is lifted from the bobbin drive roller 23 by the mechanism 7. The spinning rotor 4 driven by a tangential belt 6 or the opening roller 12 driven by a tangential belt 13 firstly continue to rotate • at operating speed. When, as shown in the embodiment according to Fig. 2, single drives 31 or 59 are provided for the spinning rotor 4 or the fibre band opening roller 12, in the event of a thread break, these drives are generally immediately switched off. After a thread break there are different procedures for repiecing the thread. For example there is the possibility of repiecing without clearing the spinning rotor. However, the generally practised method is more probable, in which the spinning device 3 is firstly cleared before repiecing. If repiecing is to take place immediately without prior cleaning of the spinning rotor, the cross-wound bobbin 22 lifted from the bobbin drive roller 23 is initially rotated manually in the unwinding 11 direction, the thread 30 which has run on to the lateral surface of the cross-wound bobbin 22 after the thread break is picked up by the operator and returned to the region of the spinning device 3. The cross-wound bobbin 22 is then fixed by the braking mechanism 50 to prevent rotation and the tightly drawn thread 30 is placed by the operator in the thread take-off mechanism 18. By actuating the control, mechanism 9, the operator then ensures that the thread takeoff mechanism 18 briefly starts to run counter to the thread takeoff direction, with a precisely predetermined thread quantity being sucked into the pneumatic thread store 37 of the workstation 2 and stored there. In the case of a generally practised, prophylactic or necessary clearing of the spinning rotor, the spinning device 3 has to be initially opened by the operator. If the spinning device 3 has a spinning rotor 4 driven by a tangential belt 6 and a fibre band opening roller 12 driven by a tangential belt 13, (embodiment Fig. 1) , these are automatically separated from their drive means on opening the spinning device 3 and run down to a standstill. The spinning rotor 4 is preferably additionally braked by a rotor brake. These rotatable components are also initially braked to a standstill in the embodiment according to Fig. 2, in which the spinning rotor 4 and the opening roller 12 are loaded by single drives. After clearing, the spinning device 3 is closed again and, for example, the spinning rotor 4 and the opening roller 12 placed on their associated tangential belts 6 or 13. The spinning rotor 4 and the opening roller 12 then run up to their operating speed. At the same time, as explained above, the thread 30 is retrieved manually from the cross-wound bobbin 22, the tightly drawn thread 30 is placed in the thread take-off mechanism 18, the thread take-off mechanism 18 is briefly driven counter to the thread take-off direction and a thread loop is formed in this case in the pneumatic thread store 37. 12 In the two cases, the thread 30 is then cut to length at the stationary device 10 which is arranged in the region of the spinning device 3 and the thread end is manually prepared for repiecing by means of a preparation mechanism 25 which in each case is in the possession of the operator. The prepared thread end is finally threaded into the thread take-off tube 11 of the spinning device and the control mechanism 9 is activated via the switching element 27. The control mechanism 9 then initiates the drive 15 of the fibre band draw-in cylinder 14, so, in conjunction with the fibre band opening roller 12, which is rotating at operating speed, in the spinning rotor 4, a fibre ring is produced. With a small, defined time delay, the control mechanism 9 also activates the drive 19 of the thread take-off mechanism 18 in such a way that a targeted thread return of the prepared thread end of the thread 30 into the spinning device 3 takes place. In other words, the thread end, in the spinning device 3, is placed on the fibre ring circulating with the spinning rotor 4 in manner so as to be precise in terms of time and length, the fibre ring is broken open and the thread 30 being newly produced is taken off from the spinning device 3 via the thread take-off mechanism 18, which was switched over to forward speed at a precise time by the control mechanism 9. At the same time, the cross-wound bobbin 22 is lowered via the mechanism 7 onto the rotating bobbin drive roller 23 and the thread 30 is wound on the winding device 33 to form a cross-wound bobbin 22. The speeds with which the fibre band draw-in cylinder 14 and the thread take-off mechanism 18 operate are thus matched precisely to the speeds of the spinning rotor 4, fibre band opening roller 12 and bobbin drive roller 23 very substantially predetermined by the group drives. 13 We Claims : 1.
