A delivery mechanism provided in front of the apparatus, wherein the delivery mechanism is provided with at least one drive roller partially wound around the yarn, and the at least one multi-yarn is wound by melt spinning. Related to the device to be formed.

2. Description of the Related Art A device of this type is known from EP-A-0 845 550.

It is known that when melt-spinning multifilament yarns, the yarns obtain different tension states. For example, the yarn tension generated when the yarn is drawn from the spinning zone is at least basically different from the yarn tension required for winding the yarn. Furthermore, it is common practice to simultaneously spin a plurality of yarns in parallel with each other and wind them in parallel with each other. In this case, the yarn is subjected to one or more treatments between the spinning operation and the winding operation. You will run through the steps. At this time, it is often impossible to avoid the occurrence of a difference in yarn tension between adjacent yarns. According to the above-mentioned EP-A-0 845 550, a delivery mechanism is arranged between the spinning device and the winding device in order to change the yarn tension of the running yarn. The delivery mechanism includes two rollers rotatably supported, at least one of which is driven. The yarn is wound around both rollers in an S-shape or a Z-shape. Since the number of drive revolutions of the rollers is changed to affect the yarn tension, the degree of peripheral speed acting on the yarn will reduce or increase the yarn tension in proportion to the yarn traveling speed. In known devices, one delivery mechanism is provided for each yarn.

An apparatus of the type in which a plurality of rollers of a delivery mechanism simultaneously guide a group of a plurality of threads extending parallel to each other along a circumference is disclosed in International Patent Publication No. 96/96.
It is known on the basis of JP 09425. However, this known solution has the disadvantage that the change of the drive speed is delayed due to the inertia of the long rollers, but individual thread processing is not possible.

[0005]

An object of the present invention is to improve a device for winding at least one multi-yarn by melt-spinning so that a traveling yarn can be driven by a delivery mechanism without changing a driving speed. That is, the thread tension can be changed.

[0006]

According to another aspect of the present invention, a roller has a guide section having an axial gradient, and a yarn can be guided along the circumference of the guide section. In addition, a guide mechanism capable of changing an abutment travel position of the yarn in the circumference of the guide section in the axial direction is assigned (or correspondingly arranged) to the roller in the yarn travel path.

The outer diameter of the guide section changes due to the inclination of the rollers in the yarn guide area. Thus, a region having a relatively small outer diameter and a region having a relatively large outer diameter are formed in the guide section. When the driving speed of the roller is set, in relation to each outer diameter of the guide section,
Different peripheral speeds can be effective. For this purpose, the abutment travel position of the yarn which is in contact with the circumference of the guide section is changed by the guide mechanism in accordance with the desired yarn tension treatment. Therefore, it is possible to generate an operation state in which the peripheral speed of the roller is higher than the yarn traveling speed, or to generate an operation state in which the peripheral speed of the roller is lower than the yarn traveling speed.

[0008] The present invention is not limited to the novel device described above, but also encompasses a novel method according to claim 17. This method is known in principle from EP-A-0 845 550 mentioned at the beginning of the specification or from EP-A-0 539 866. In a known manner,
The yarn is guided along the circumference of the drive roller at a set yarn traveling speed in order to change the yarn tension of the traveling yarn. In that case,
The ratio between the roller peripheral speed acting on the yarn and the yarn running speed of the yarn is
It is controlled by a change in the driving speed of the roller. On the other hand, in the method of the present invention, the ratio between the peripheral speed of the roller acting on the yarn and the traveling speed of the yarn is controlled only by a change in the abutting traveling position of the yarn on the roller circumference. For this purpose, the yarn is guided along the circumference of a guide section of the roller formed with a gradient.

A particularly significant advantage of the present invention is that it allows precise adjustment of the thread tension and subtle changes in the thread tension. In this case, it is particularly advantageous if the guide section is frusto-conical.

[0010] A particularly advantageous embodiment of the invention as defined in claim 3 or claim 18 makes it possible to maintain a set yarn tension of the running yarn during the process. For this purpose, when the abutment travel position of the yarn in contact with the circumference of the guide section deviates from the target value of the yarn tension, the abutment travel position is shifted toward a smaller diameter of the guide section or toward the guide section. The guide mechanism is controlled or adjusted in relation to the target value of the thread tension of the thread so as to change towards a larger diameter of the thread. As a result, the yarn tension, in particular immediately before the winding device, is adjusted to a constant target value, irrespective of the previously applied yarn tension. For example, if the yarn tension falls below the target value in the yarn running path behind the delivery mechanism, the yarn supplied to the roller at a substantially constant yarn running speed will be increased based on the smaller diameter of the guide section. The contact running position is changed so as to be exposed to a small peripheral speed. As a result, the yarn is braked, so that a higher yarn tension is generated behind the roller as viewed in the yarn traveling path. When the target value of the yarn tension exceeds the target value, the peripheral speed is increased by a corresponding change in the running position of the yarn, so that a slip occurs between the roller and the yarn at a constant yarn running speed. Will be. As a result, the yarn tension is reduced, so that the yarn tension acting behind the roller as viewed in the yarn traveling path decreases.

In order to change the abutment travel position of the yarn, a guide mechanism according to an advantageous embodiment of the invention comprises a yarn guide reciprocally reciprocable in a transverse direction perpendicular to the yarn travel path; And a power generator cooperating therewith. In this case, the power generator controls the position of the thread guide relative to the thread tension. In this case, pins, eye rings, rollers or slit guides can be used as thread guides.

Depending on the configuration of the power generator, a mechanically automatic guiding mechanism as in an advantageous embodiment according to claim 5 or an electric control as in an advantageous embodiment according to claim 9 It is possible to configure a guide mechanism of the type or the electric adjustment type.

According to an embodiment of the device according to the invention, the power generator is configured as a pre-loaded spring. In this case, the spring generates a deflection force acting in the transverse direction perpendicular to the yarn traveling path along the yarn guide. The position of the thread guide is thus determined on the one hand by the generated deflection forces and on the other hand by the forces acting along the thread guide as a result of the thread tension.
The position of the thread guide is thus determined by the balance of the forces acting along the thread guide. In this embodiment of the device according to the invention, the thread guide has two functions: to guide the thread and to sense the thread tension. This embodiment is therefore particularly suitable for equalizing the yarn tension in the yarn running path in front of the roller.

The target value of the thread tension is influenced by the spring force based on the fact that the spring is preloaded. In order to change the desired value of the thread tension, it is proposed according to an advantageous embodiment to tension a spring between the pivotable guide bar and the holder. In this case, the free end of the guide bar acts as a thread guide. Since the position of the holder is variable with respect to the rotation axis of the guide rod, it is possible to set various target thread tension values.

In a particularly advantageous embodiment of the device according to the invention, both guide ends of one guide bar are used for thread guidance. In this case, one guide end guides the yarn in front of the guide section of the roller as viewed in the yarn traveling path,
The other guide end for this guides the yarn behind the guide section of the roller as viewed in the yarn travel path. The guide rod is supported so as to be pivotable about a pivot axis. Since one stationary thread guide is arranged between the guide end located behind the roller and the guide section as viewed in the yarn travel path, when the guide rod swings, the thread in the guide section is hit. While the contact running position is changed, the winding of the yarn in the yarn guide disposed downstream of the roller is also changed. With this configuration, the "yarn guide" function and the "yarn tension detection" function are separated so that the yarn tension is substantially detected in the yarn traveling path at the rear of the roller. Therefore, it is possible to advantageously influence the yarn tension behind the roller as viewed in the yarn traveling path.

If an automatic mechanical guide mechanism is used, the position of the thread guide can be simplified in a simple manner by additionally arranging a monitoring device and a position sensor. Can be grasped electronically. This enables thread break monitoring and / or thread tension measurement and is used for controlling the device and / or for quality assurance.

In a yarn spinning apparatus, a tension sensor is often used for quality maintenance. In the case of such a device, the guide mechanism can be configured in a simple manner as can be seen from the advantageous embodiment of the device according to the invention. For this purpose, controllable actuators are used as power generators. The actuator is connected to a controller provided with a tension sensor for detecting the yarn tension of the traveling yarn. In this case, a comparison between the actual value and the target value takes place inside the controller, and if a difference value is ascertained, a corresponding control signal is generated and transmitted to the actuator. In response to the control signal, the actuator changes the contact traveling position of the thread guide.

Whether the yarn tension at the rear of the roller as viewed in the yarn traveling path, that is, the yarn tension immediately before the winding device, or whether the yarn tension at the front of the roller near the spinning device as viewed in the yarn traveling path is changed. The tension sensor is arranged in front of the roller as viewed in the yarn travel path or behind the roller as viewed in the yarn travel path.

In a particularly advantageous embodiment of the invention, the controller is also connected to a roller drive for the rollers. Therefore, in order to change the peripheral speed at the roller, it is possible to directly superimpose by changing the abutment running position of the yarn and by changing the driving speed of the roller.

In order to change the peripheral speed of the rollers, the guide section can be designed to have a substantially constant gradient. However, if it is necessary to bridge a relatively large thread tension range, it is also possible to configure the guide sections of the rollers with a stepwise gradient. It is also possible to configure the gradient in a curved manner, or to configure curved sections with different curvatures, in which case the transition points extend, for example, in the tangential direction.

In order to obtain a yarn running speed which is as uniform as possible, it is proposed according to an advantageous embodiment of the invention to provide the delivery mechanism with two drive rollers. The two drive rollers are then advantageously driven by a common drive.

The advantageous embodiment of the invention according to claim 15 is particularly advantageous because, during melt spinning, a plurality of yarns are spun and wound simultaneously in parallel as usual, and are wound. A plurality of guide sections are formed along the rollers. Each thread has one guide section on the roller,
A guide mechanism cooperating with the guide section is assigned.

In the case of one roller with a plurality of guide sections, the guide mechanisms are advantageously arranged in a row. In this case, the yarn guides of the guide mechanisms can be controlled by one power generator or collectively by one common power generator.

[0024] Further advantageous embodiments of the invention are specified in the dependent claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 schematically shows a first embodiment of the device according to the invention. This apparatus includes a spinning device 1, a delivery mechanism 2 disposed below the spinning device 1, and a winding device 3 disposed below the delivery mechanism 2. In the spinning device 1, as shown in the drawing, one spinning beam 4 is shown, but a plurality of spinning nozzles 5 are arranged in parallel on the lower surface of the spinning beam. Below the spinning beam 4, a cooling cylinder 7 is provided for cooling the filament bundle 6 extruded through the spinning nozzle 5. At the outlet of the cooling cylinder 7, one filament 9
A plurality of collective yarn guides 8 are arranged in order to form. The spinning apparatus 1 of the present embodiment has a total of four yarns 9.1 and 9.1.
Suitable for co-spinning 9.2, 9.3, 9.4.

The delivery mechanism 2 disposed below the spinning device 1 comprises rollers 12 and 13. Roller 12
Is disposed before the roller 13 as viewed in the yarn traveling path. For this purpose, the roller 12 is rotatably supported by a roller support 14. The roller support 14 is fixed to a machine base 16. In this embodiment, the roller support 14 is configured to support the roller 12 at each shaft end. The roller 12 is connected to a driving device (not shown) at an end near the machine base 16. A second roller support 15 is arranged on the machine base 16 at a distance from the roller support 14. The roller support 15 serves to support the roller 13. The roller 13 is also connected to a drive unit, not shown, at the end of the machine base 16. The rollers 12 and 13 are advantageously driven together by one drive. The rollers 13 each have a guide section 17 in the yarn guiding area. In this embodiment, a total of four guidance sections 17.1,
17.2, 17.3, 17.4 are formed. The guidance section 17 will be described later in detail.

The roller 13 is provided with a plurality of guide mechanisms 18.1, 18.2, 18.3, and 18.4 in front of the yarn traveling path. In this embodiment, the guide mechanism 18.1 is in the guide section 17.1 on the roller 13, the guide mechanism 18.2 is in the guide section 17.2, and the guide mechanism 18.3 is in the guide section 17.3.
In addition, the guide mechanism 18.4 is arranged corresponding to the guide section 17.4. The structure and function of the guide mechanism will be described later in detail. The guide mechanism 18 includes the mechanical base 16.
Is mounted on a support 30 which is also fixedly connected.
The yarn is partially wound around each of the rollers 12 and 13.

Below the delivery mechanism 2, the yarns 9.1 to 9.1 are provided.
A winding device 3 is provided for winding 9.4 into packages 26.1 to 26.4, respectively. Package 26
Is formed on a winding spindle 24 driven via a spindle driving device 25. In this case, each yarn is supplied to the package 26 via the top yarn guide 21, the traverse device 22, and the pressure roller 23 which is in contact with the outer periphery of the package.

In the apparatus shown in FIG. 1, the polymer melt is
For example, it is supplied to the spinning device 1 by an extruder. Inside the spinning beam 4, the polymer melt is supplied to a spinning nozzle 5 via a spinning pump, and each spinning nozzle having a large number of nozzle holes extrudes a filament bundle 6. Each of the filament bundles 6 is collected into one yarn, and is drawn from the spinning device 1 via the delivery mechanism 2. In the region of the delivery mechanism 2, the yarn 9 is subjected to a yarn tension treatment, that is, the yarn pulled out by the winding device 3 is treated so as to have substantially equal tension values. The function for performing the yarn tension processing inside the delivery mechanism 2 will be described later in detail.

The yarn 9 is fed to the delivery mechanism 2 for yarn tension processing.
Into each other in parallel. As shown in FIG. 2, the rollers 12 and 13 are arranged so that the yarn 9 is wound around the delivery mechanism 2 in a Z-shape. Roller 12,1
The yarn 9 has a substantially constant yarn running speed in each case, since the yarn 3 is driven at a constant speed in each case. For the thread guidance, the rollers 13 are each provided with one guide section 1 around the circumference.
7. The guide section 17 is formed in a frusto-conical shape having a gradient in the axial direction of the roller 13. Therefore, the guide section 17 has an outer diameter that increases and decreases in the axial direction of the roller 13 to guide the yarn. The guide section 17 of the roller 13 is provided with a guide mechanism 18 in front of it. The guide mechanism 18 comprises a movable yarn guide 20 and a power generator 19 for regulating the contact running position of the yarn 9 in the guide section 17 in relation to the yarn tension. When the yarn traveling path is adjusted by the guide mechanism 18, the yarn 9 is
The delivery mechanism 2 is provided with a thread guide 11.1 at the entrance of the delivery mechanism 2 in order to prevent movement in the axial direction along the line.

The yarn is then wound up in winding device 3 to form package 26.

FIG. 3 shows an automatic mechanical guide mechanism 18.
Is shown in FIG. In this case, the movable yarn guide 20 is formed by one guide rod 29. The guide rod 2
9 is rotatably supported at one end by a turning shaft 27. The pivot 27 is fixedly arranged on the support 30. The power generator 19 is formed by a tension spring 28. For this purpose, the tension spring comprises a holder 31 fixed to a support 30 at a distance from the pivot 27 and a guide rod 29.
It is stretched between.

The illustrations in FIGS. 3.1, 3.2 and 3.3 show the cooperation between the guide mechanism 18 and the guide section 17 on the roller 13. The drawing shows the first roller 12
FIG. 5 is a view as seen in the traveling direction of a yarn 9 conveyed obliquely from the second roller 13 to a second roller 13. However, the first roller 12 is not shown. The thread 9 is lightly contacted by a spring-loaded guide rod 29. The guide rod 29 is in a position perpendicular to the support 30 for the first thread tension (FIG. 3.1). During the further travel of the yarn, the yarn 9 reaches the frustoconical guide section 17 of the roller 13.

In FIG. 3.2, the guide rod 29 has been tilted slightly to the right, so that the thread 9 has been axially shifted on the guide section 17 of the roller 13. That is, the guide rod 29 is displaced based on the smaller second thread tension. By the way, if the number of rotations of the roller is constant, the yarn 9 is conveyed on a larger circumferential section of the roller 13. As the peripheral speed increases in proportion to the set yarn traveling speed, the yarn tension in the yarn traveling path in front of the roller increases. As a result, an increased resultant force acts on the guide rod 29, and the guide rod 29 is returned to the vertical position.

FIG. 3.3 shows the guide rod 29 in a position tilted to the left. This position is obtained if the thread 9 has a significantly higher third thread tension. The thread 9 runs on the guide section 17 of the roller 13 towards the area with the smaller diameter. Since the peripheral speed becomes low, the yarn tension in front of the roller as viewed in the yarn traveling path becomes smaller based on the ratio between the peripheral speed and the yarn traveling speed. Thus, the guide rod 29
Pushes the thread 9 back to a vertical position where the peripheral speed will generate the desired thread tension. Therefore, the desired thread tension specified as the target value by the spring force is automatically maintained. Therefore, the yarn tension of the yarns running in parallel to each other can be equalized without adjusting the driving speed of the roller 13. In practice, the pivoting movement of the guide rod 29 is significantly reduced. This is because the variation in thread tension is relatively small in terms of process and the system immediately corrects for force deviations.

FIG. 4 shows another embodiment of a guide mechanism, such as can be employed in the device shown in FIG. In this case, a plurality of guide mechanisms are arranged along one tubular support 30. In FIG.
1, 18.2 are shown. Each guide mechanism 18.1,
18.2 is formed by a pivotally mounted guide rod 29 and a tension spring 28, respectively. For this purpose, the guide rod 29 is supported at one end by a pivot 27. The guide end of the guide rod 29 opposite to the end is located outside the support 30 for guiding one thread. A holder 31 is provided at a distance from the turning shaft 27, and is for holding a spring 28 stretched between the holder 31 and the guide rod 29. The holder 31 is a shift rod 32
It is fixed to. The shift rod 32 is connected to each guide mechanism 1.
It is used for mounting the holder 31 arranged in 8.1, 18.2. The shift rod 32 is connected to one adjusting means 33. The adjusting means 33 can in this case be configured, for example, as an adjusting screw. Adjusting means 33
, The distance between the turning shaft 27 and the position of the holder 31 can be adjusted each time, so that the spring force can be varied to adjust the set thread tension. The adjusting force in that case acts equally on all the guide mechanisms 18 arranged on the support 30.

FIG. 5 schematically shows an embodiment of a guide mechanism capable of turning into a yarn running path. In FIG. 5.1, the guide mechanism 18 is in the operating position, and in FIG. 5.2, the guide mechanism 18 is in the inoperative position. In this case, the guide mechanism
It may have the structure described in FIG. Support 30
Is connected to a swing arm 34 via a rotary joint 35. The swivel arm 34 is connected to a machine base by a swivel bearing 36. At the start of the spinning process, the guide mechanism 18 is initially in the inactive position shown in FIG. 5.2. The thread 9 is guided by rollers 13. After the end of the thread contact process with the rollers, the guide mechanism 18 is pivoted by the pivot arm 34 into the operating position shown in FIG. The thread guide of the guiding mechanism catches the thread 9 and thus determines the abutment position of the thread in the guide section 17 of the roller 13.

FIG. 6 shows a second embodiment of the apparatus of the present invention. The structure of this embodiment of the device according to the invention largely corresponds to the preceding embodiment shown in FIG. 1, so that reference is made to the above description. Here, only the substantial differences will be described.

FIG. 6 shows a yarn traveling path of one yarn. In this embodiment, a processing device 37 is provided between the spinning device 1 and the delivery mechanism 2. In this case, the processing device 37 has a drawing mechanism including a plurality of godet rollers in order to draw one or a plurality of yarns from the spinning device and draw the yarn. The structure of the processing device 37 is merely exemplary and substantially related to the manufacturing process.

The delivery mechanism 2 includes a first roller 12 rotatably supported by a cantilever, and a second roller 13 also rotatably supported by a cantilever. The first roller 12 is driven via a roller driving device 47. The second roller 13 is driven via a roller driving device 48. The rollers 12 and 13 are connected to each other in the delivery mechanism 2 by S
It is arranged in the yarn running path so as to generate a letter-shaped yarn winding. The second roller 13 has a frusto-conical guide section 17. The guide section 17 is in this case a roller 1
3 extending over the full width of 3. One guide mechanism 18 is provided in the yarn traveling path between the first roller 12 and the second roller 13. The guide mechanism in this case has a power generator configured as a controllable actuator 40. The actuator 40 is connected to the movable thread guide 20. Actuator 40 is controlled via controller 38. For this purpose, the controller 38 is operatively connected to a yarn tension sensor 39. The yarn tension sensor 39 is arranged in the yarn traveling path between the delivery mechanism 2 and the winding device 3. Furthermore, the controller 38 is connected to a roller drive 48.

In the device according to the invention shown in FIG. 6, the yarn 9 is fed to the winding device 3 with a substantially uniform yarn tension.
For this purpose, the yarn tension is measured by a yarn tension sensor 39 just before the entrance to the winding device. The measurement signal is sent to the controller 38
Is transmitted to Within the controller 38, the actual value and the target value of the yarn tension are compared, and if a difference value exists, a control signal is generated. The control signal is transmitted to an actuator 40, which adjusts the movable thread guide 20 so as to change the abutment running position of the second roller 13 in the guide section 17. If an excessively high yarn tension is measured in the yarn running path behind the second roller 13, the movable yarn guide 2
0 is the contact running position of the yarn in the guide section 17;
It is adjusted so that the diameter of the guide section shifts in the direction of larger diameter. Accordingly, the second roller 13 generates a higher peripheral speed that causes a slip between the second roller 13 and the yarn 9 when the yarn traveling speed is adjusted to be constant. Accordingly, the yarn tension is reduced, so that the yarn tension in the yarn traveling path behind the second roller 13 is reduced. Therefore, based on the sensor signal generated by the yarn tension sensor 39, the yarn running is always adapted to the set target value of the yarn tension.

A delivery mechanism for guiding a plurality of yarns in parallel with each other is configured as shown in FIG. In this case, a pair of rollers consisting of a first roller 12 and a second roller 13 is arranged corresponding to each yarn. In FIG. 7, the first
The three working parts consisting of the first roller 12.1, 12.2, 12.3 and the second roller 13.1, 13.2, 13.3 are shown. All the rollers are supported by a single machine base 16 and can be driven individually or collectively. Each second roller 13 has a frustoconical guide section 17.1, 17.
2,17.3. Each first roller 12 is provided with a yarn guide 11.1 and each second roller 13 is provided with a yarn guide 11.2. Guide mechanisms 18.1, 18.2, and 18.3 are provided in the yarn traveling path between the first roller 12 and the second roller 13, respectively. In this case, the movable yarn guides 20.1, 2 of each guide mechanism 18
Both 0.2 and 20.3 are controlled by one power generator 19. Power generator 19 and movable yarn guide 20.1, 2
Power transmission between 0.2 and 20.3 takes place via a link rod 46.

FIGS. 8 and 9 illustrate another embodiment of a delivery mechanism such as may be employed in the apparatus illustrated in FIGS. In this case, the yarn tension of the yarn 9 is controlled just before the entrance to the winding device 3. This embodiment can be used when there is a risk that the winding device 3 or the package will cause a fluctuation in the yarn tension.

FIG. 8 schematically shows a front view of the delivery mechanism. The first roller 12 supplies the yarn 9.
The yarn from the first roller 12 is conveyed to the second roller 13 along a vertical path. The yarn is wound around the second roller 13 at a winding angle of 180 ° and guided to the top yarn guide 21 of the winding device 3. Below the second roller 13, a guide mechanism is provided, which is equipped with a pivotable guide rod 41 having two guide ends 42,43. In this case, the thread 9 is guided by the guide end 42 before riding on the second roller 13 and by the guide end 43 after exiting from the roller 13. A yarn guide 11.2 is arranged between the guide end 43 and the second roller 13.

FIG. 9 is a schematic plan view showing the arrangement of the winding device 3. FIG. 9.1, FIG. 9.2 and FIG.
3, the second roller 13 with one guide section 17
Are shown, in which case the roller 13 is partially covered by a support 44. The thread 9 rides on the guide section 17 on the right side of the roller and is again delivered on the left side of the roller and again on the left side of the roller. Thread 9 before riding
Are contacted by a first guide end 42, which determines the riding position of the thread 9 in the guide section 17 of the second roller 13. Thread guide 11.2 is thread 9
Guides the thread after the roller 13 has separated from the roller 13. Then the second guide end 43 of the guide rod 41 comes into contact with the thread. The guide rod 41 is rotatably mounted on the turning shaft 45 and is connected to the power generator 19. For this purpose, the power generator 19 has a spring 28, which is provided with a guide rod 41.
And a holder 31. Holder 31
Can be shifted relative to the support 44,
Different spring forces can be adjusted. Guide rod 4
1 is configured such that a lever arm on a yarn advancing side in front of the winding device is longer than a lever arm on a yarn advancing side between rollers. This ensures that the yarn tension before the winding device is the guide control quantity.

In FIG. 9.1, a spring-loaded guide rod 41 is shown.
Shows how the yarn 9 is shifted to the right after the advance from the roller 13. At this position, the desired yarn tension occurs before the winding device. The thread 9 then runs automatically by the guide end 42 to the desired position in the guide section 17.

FIG. 9.2 shows the yarn 9 loaded by undesirably high yarn tension. Both yarn guides 11.
Between 1.1 and 11.2 the thread 9 is effectively tensioned as if it were a plumbing cable. The guide end 43 is shifted toward the left hand against the spring force. Based on this, the guide end 42 is displaced toward the right hand. The thread 9 now travels along the roller 13 at the position where the diameter of the guide section 17 increases. As a result, the yarn 9 is conveyed at a higher peripheral speed, so that the yarn tension before the winding device is reduced and the guide rod 41 is displaced back to the position shown in FIG. 9.1.

FIG. 9.3 shows a yarn 9 having a low yarn tension before the winding device 3. Guide rod 43 is thread 9
, So that the guide end 42 has displaced the thread 9 towards the smaller diameter of the guide section 17. As a result, the yarn conveying speed is reduced, and the yarn tension before the winding device 3 is immediately increased. Swivel axis 4
Due to the difference in lever arm length with respect to 5, a reliable operation mode can be obtained. In this case, the yarn tension acting within the yarn that advances along the guide end 43 is always in front of the winding device.
Guiding the opposite guiding end 42 is guaranteed.

This function can be applied to the individual delivery mechanisms shown in FIG. 3 to 5, 8
