[Prior Art 3] This type of device is known from the German Patent No. DE 44 16 136 A1. For the purpose of spinning and winding a synthetic yarn, the known device comprises a spinning element, a first A driven godet and a second driven godet also include an access element. In this apparatus, the first godet driven by an electric motor is taken out from a spinneret of the spinning element after a melt spinning step. Therefore, the yarn partially rewinds around the first godet. An electric motor similarly drives a second godet located downstream of the first godet and has a speed differential that is adjusted between the first and second godets. The magnitude of the speed difference depends on the type of yarn produced. When producing a composite multifilament yarn from a thermoplastic melt, it is basically distinguishable from partial drawing and full drawing. Partial drawdown includes a predetermined molecular structure that requires a subsequent draw of 20 of the second processing step. It is called a predetermined orientation (POY) yarn. In comparison, the fully drawn (FDY) yarn is directly suitable for further processing without subsequent drawing. Therefore, it is known that for the production of FDY yarns, it is necessary to adjust the large speed difference between the godets. Conversely, when spinning and winding a predetermined yarn, a small speed difference is required between the godets. When producing POY polyester yarns, the speed difference is, for example, in the range of 0.1% to 1252879 0.5%. Therefore, it is necessary to achieve and maintain the speed adjusted on each godet with high precision during processing. Thus, in the case of known devices, a control element is often coupled to each electric motor so that each electric motor can be controlled by a nominal frequency that determines the speed. Therefore, the requirements for the control elements are the same in each process variation example 5, regardless of the magnitude of the speed difference. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to improve a 10 as an initial description by providing a small speed difference between a first driven godet and a second driven godet. A type of device that requires very few control elements while maintaining high accuracy. According to the invention, this object is achieved by providing a control element for both electric motors, which control the electric motor at a nominal frequency and which makes an electric motor a non-synchronous motor and which has a corresponding The speed difference of 15 degrees is worse. The present invention makes use of the knowledge that a non-synchronous motor activated by a nominal frequency produces a lower actual frequency due to the speed variability required by its principle and therefore has a lower drive speed. Therefore, it is possible to realize a speed difference of about 20 with a speed slip in a simple manner without requiring an additional control member. In order to be able to adjust and vary the speed difference, a further development of the invention will be particularly advantageous, wherein the control element includes a variable voltage/frequency ratio by which the non-synchronous motor can be controlled to vary the speed slip. The ratio of voltage to frequency will affect the magnetization of the non-synchronous motor, resulting in a change in speed slip 1252879 . Based on the robustness of the non-synchronous motor, slight over-magnetization or insufficient magnetization is not important, so the adjustment of the speed slip can be made without significant loss. In another particularly advantageous further development of the invention, an inductor is coupled to the non-synchronous motor. Use this sensor to measure the actual frequency 5 . The sensor is connected to the control element via a signal line. Therefore, in the control element, the separately adjusted slip condition of the asynchronous motor may be determined from the actual frequency and the nominal frequency, so that the required voltage/frequency ratio can be directly matched. The speed is poor. Thereby, it is possible to control during the operation, such as by the advantageous irregularities occurring by the load change, so that an actual frequency and thus a peripheral speed of one of the guidewire discs, respectively, 10 are kept substantially constant during the overall operating cycle. . A non-synchronous motor operating in this manner can drive the second godet and the first godet as a function of the yarn produced. In the case where the second godet is driven by a lower actual frequency that deviates from the nominal frequency, a speed difference is obtained, 15 resulting in a decrease in yarn tension between the first and second godets. In this case, the first godet is driven at a higher peripheral speed than the second godet. In the case where it is desired to slightly increase the yarn tension, the first godet can be advantageously driven by the asynchronous motor. In this manner, the first godet is driven at a lower 20 speeds than the second godet as a result of the speed of the non-synchronous motor. In order to be able to adjust the speed difference with a non-synchronous motor with as large an overall overall speed range as possible during the operation of the godet, an advantageous further development of the invention proposes to form by means of a synchronous motor or a reluctance motor Other electric motors. Thereby, it is possible to drive 1252879 to drive a godet at a speed corresponding to the nominal frequency. There is also the possibility of 各 π water privately moving the two godets by means of a non-synchronous motor. Therefore, it should be noted that a non-synchronized horse, ~t is as electrically "soft" as possible, that is, has a corresponding large speed slip, B * _ left and it can be changed as a function of voltage / frequency ratio. In comparison, the non-synchronous motor made by the 一 缔 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , In an advantageous case, the control mode of the different + 14 v motor can be arranged, so as to control the electric non-synchronous motor of "just 10 / / ” via a frequency control, and control the electrical "softness" via the volt / Hertz ratio. The non-synchronous motor in the case where the first godet disk and the second godet disk have a large speed difference, 'may be determined by the diameter ratio of the outer diameter of the first and second godet disks - Basic adjustment. For example, it is possible to provide the second godet with a larger outer diameter than the diameter of the first godet housing, thereby utilizing the same 15 frequency adjustment to obtain a greater peripheral speed on the second godet. . To finely set the basic adjustment of the speed difference, use the speed difference control of the non-synchronous motor. Depending on the particular process, the first wire reel and/or the second god wire reel may include additional heating means for heating the peripherals so that heat 20 treatment may be performed on the yarn. The method of the present invention having the steps according to the tenth aspect of the patent application is characterized in that it requires a control member for maintaining a speed difference between the two godets with high precision. The method of the present invention advantageously advantageously includes a speed slip of 1252879 in the control of the speed difference between the two discs including the principle of a non-synchronous motor, which is often found to be disadvantageous. Thereby, it is possible to advantageously achieve a mainly small speed difference. Therefore, it is preferred to control the speed difference by predetermining and changing the volts/hertz ratio on the associated control elements. The nominal frequency provided in each case at a different volt/Hz ratio will result in a change in the speed of the activated non-synchronous motor. The apparatus and method of the present invention are particularly suitable for forming synthetic yarns into so-called POY yarns. In this treatment, a polymer such as polyester, polyamide or polypropylene can be used. BRIEF DESCRIPTION OF THE DRAWINGS In the following, other advantages of the invention will be described in detail by way of an embodiment of a device according to the invention, wherein: Figure 1 is a schematic view of a first embodiment of a device according to the invention; Figure 2 is a schematic cutaway view of another embodiment of the apparatus in accordance with the present invention. I: Embodiment 1 Detailed Description of the Preferred Embodiment Fig. 1 is a schematic view showing a first embodiment of the apparatus according to the present invention. For a melt spinning operation, the apparatus of the present invention comprises a spinning element 1. In the embodiment of Fig. 20, the spinning element 1 is formed by a spinning head 3 and a spinneret 4 arranged on the bottom side of the spinning head 3. The spinning head 3 includes a spinning pump and a distribution line (not shown) and is coupled to a plurality of spinnerets. Therefore, the spinning head 3 has a configuration that can be heated. A polymer melt is supplied to the spinning head 3 via a melt supply line 2. For the sake of clarity, this embodiment only shows the path of a 1252879 yarn. The spinneret 4, located on the bottom side of the spinneret 3, comprises a plurality of nozzle apertures through which the polymer melt can be extruded under pressure through a plurality of nozzle apertures. Thus, a plurality of strands of filaments for forming a bundle 5 are separated from the spinneret 4 by 5. Directly downstream of the spinneret 4, a cold section for cooling the as-extruded tow is provided. In the illustrated embodiment, the cooling element 6 is realized by an air flow system for directing a flow of cooling air from the outside to the tow 5. Downstream of the cooling element 6, a yarn lubricating element 7 and a yarn guide 8 are provided, whereby the tow 5 is combined into a single yarn 9. 10 The first guidewire disc 10 and the second guidewire disc 13 are partially retracted by the yarn 9 to extend in the direction of the advancement yarn. - As a synchronous motor 11 form & electric motor is coupled to the _ guide wire disc 1 (). The second guide boat 3, which is downstream of the first godet 1 and extends, is driven by an electric motor which is a non-synchronous motor 14. In order to control the synchronous motor n and the asynchronous motor 14, the control element 12 is provided. The synchronous motor 11 is connected to the control element via a control line 19·2, and the asynchronous motor 14 is connected to the control element u via a control line 191. The non-synchronous motor 14 includes a rotary de-energator 15 and is coupled to the control element 12 via a signal line 20.1. In order to receive and store the yarn 9, an access member 16 is arranged downstream of the second godet 2〇13. In the take-up element 16, the yarn 9 is wound onto a package 17 formed on a rotating winding mandrel 18. In the embodiment shown in Fig. 1, the yarn 9 is taken out from the rotary member by the first godet 10 and the second godet 13. In this process, the first godet 1 and the first godet 13 are driven at a speed difference. In order to drive the first godet 1 1 1 1252879, the control element 12 receives a nominal frequency f nominal. Via the control line 19·2, the control element 12 causes the synchronous motor U to be activated by the nominal frequency f. Therefore, the first godet 1 has a peripheral speed corresponding to the nominal frequency f. Via the control line 19·1, the asynchronous motor 14 likewise receives the nominal frequency f 5 «to be activated. Based on a speed slip of the asynchronous motor 14, the second godet 13 reaches a peripheral speed corresponding to a nominally smaller actual frequency than the predetermined nominal frequency f. Therefore, the second godet 13 has a lower peripheral speed than the first godet 10, so that a speed difference can be operated between the two godets 1 and 13. 10 The required speed difference between the first godet 10 and the second godet 13 is input to the control element 12 in a nominal frequency difference. In order to adjust and control the predetermined speed difference, the respective actual frequencies fV are measured in the asynchronous motor 经由 via the rotatable frequency sensor 15, and supplied to the control element 12 via the signal line 2〇1. The difference between the nominal frequency f# and the actual frequency 15 heart rate is formed in the control element 12 to determine the actual value of the respective frequency difference and compared with the set value of the frequency difference. In the case of a deviation, the manner in which a predetermined voltage/frequency ratio V/f varies within the control element 12 can be nominally caused by an unaltered nominal frequency f in a rotational slip in the asynchronous motor 14. Change, resulting in a change in the actual frequency. Thereby, it is possible to adjust and maintain a predetermined speed difference between the first godet 10 and the second godet 13. For example, it is possible to determine that the voltage/frequency ratio at 1⁄4 volt/Hz has a speed difference of 〇·2% in the case of operating one asynchronous motor at a driving speed of 3000 m/min. For the same drive speed, the voltage/frequency ratio is in the control element 12 in the dragon G.8 volts/Hz. This results in a speed difference of 1252879 up to 0.6% in the non-synchronous motor. In the production of the Υ0 crepe, the first godet 10 and the second godet 13 operate at a speed difference in the range of 0.1 to 0.5%, so that a slight change in the voltage/frequency ratio is sufficient to cover the overall speed difference range. Therefore, the excessive magnetization or magnetization that is simultaneously performed on one of the non-synchronized motors remains within the narrow limit and has no effect. The yarn 9 advances over the first godet 1 and the second godet 13 without being drawn, and is then wound into the package 17 in the pick-up element 16. The winding step is preferably carried out by a process in the form of a entanglement which improves the further processing. The yarn tension required for entanglement can also be advantageously adjusted by the speed difference that can be manipulated between the godets 1 and 13. Thereby, the embodiment of Fig. 1 is advantageously adapted for spinning and winding crepe. Figure 2 is a cutaway view of another embodiment in which the spinning element 1 is not shown and the access element 16 is not shown. These elements are the same as the above embodiments, so the above description is hereby incorporated by reference. The yarn 9 is withdrawn from the spinning element via the first godet 1015. Therefore, the first godet 1 has an outer casing of diameter 〇!.

The first godet 10 is driven by a non-synchronous motor 21, and the asynchronous motor 21 is coupled to a control unit 12 via a control line 2〇2. A rotatable frequency sensor 22 coupled to the control element 12 via a signal line 2〇·2 is coupled to the asynchronous motor 21. According to the above embodiment, the second godet 13 is driven by the non-synchronous motor 14 12 1252879. The asynchronous motor 14 is connected to the control element via a control line 191, and the tamper element 12 is connected via a signal line 2 (U to the rotatable fresh sensor 15 of the asynchronous motor 14. The non-synchronous motor of the second godet 13 The activation and control system has a consistent manner of occurrence with the above-described embodiment of the Figure 1, so that the above-described embodiment 5 is incorporated herein by reference. Compared to the non-synchronous motor 14 of the second godet 13, The two asynchronous motors 21 are made electrically "rigid." Therefore, the asynchronous motor 21 has a lower speed slip which is substantially independent of the selected voltage/frequency ratio. The peripheral speed, the rotatable frequency sensor, the amount W, measures the actual frequency on the non-synchronous motor 21 and supplies it to the control element. In the control element 12, a comparison occurs between the actual frequency and the nominal frequency, Thereby, the nominal frequency is corrected. The corrected nominal frequency is supplied to the asynchronous motor 21, whereby the required peripheral speed is achieved on the first godet 1〇. The first godet 10 and the second godet 13 Between because there are different 15 selected outside The diameters D1 and D2 can operate a speed difference. The speed difference caused by the geometry is predetermined as the basic adjustment of the speed difference. In order to maintain a selected speed difference higher or lower than the basic adjustment tip, The driving system of the two godets 13 has a control and adjustment manner consistent with the above embodiment. Therefore, it is possible to adjust the entire predetermined speed difference by the speed slip of the asynchronous motor 14 and keep it substantially fixed. The embodiment shown in Fig. 2 can be partially depicted in the winding step such as the yarn 9. The variation of this method is particularly advantageous when the temperature difference is greater than 〇·1 to 0.5%. The mounting and application of the embodiments are merely exemplary. Therefore, it is possible to replace and merge the drivers of the first and second godets with 13 1252879. Similarly, the yarns can be used to wrap the first and second godets several times. The two godets can be operated at the same speed by selecting different casing diameters, so there is no operational speed difference. Similarly, it is possible to couple the freely rotatable rollers to the guides shown in Figures 1 and 25. The wire disc advances the yarn having several windings, and the yarn may undergo heat treatment, wherein at least one of the godet disks includes a heating member for heating the outer casing.
