[0004] Device for guiding a yarn

[0005] The present invention relates to a device and a method for guiding at least one gam for the production of an effect gam as well as a textile machine for the production of a fantasy gam with such a device.

[0006] In the production of fantasy yarns, filament yarns, usually in their fully drawn state (FDY), are given bulk using a swirling or texturing nozzle. At least two yarns, or components, are combined in this process. The first component is a core yarn, and the second component is an effect yarn, which is arranged around the core yarn through texturing or swirling. The core yarn, which enters the texturing nozzle at a continuous speed, determines the firmness of the fantasy yarn. The effect yarn determines the tactile and visual properties of the fantasy yarn, such as its bulk or color gradient. The bulkiness of the fantasy yarn is further determined by the relative speeds at which the effect yarns enter the swirling or texturing nozzle.The more effect yarn per unit length of core yarn enters the nozzle, i.e., the faster the effect yarn enters the nozzle relative to the core yarn, the bulkier the resulting yarn becomes. If this bulkiness changes along the yarn's path, it is referred to as a so-called fantasy or effect yarn; otherwise, it is called a textured or swirled yarn. The term effect yarn is used both for the final yarn produced by the textile machine and for individual components used in the production of the endgame. In the following, the term effect yarn will only be used to describe a component of the endgame, while the term fantasy yarn will be used for the final yarn produced by the textile machine. It is known from the prior art to vary the bulkiness of the produced fantasy yarn. This is achieved by varying the amount of effect yarn supplied to the inlet of the texturing nozzle per unit of time, i.e., by varying the feed rate of the effect yarn. 08 / 08 / 2025.

[0009] From WO 2009 / 033697 A1, a device for producing effect yarns during yarn texturing by generating flames through brief yarn exposure is known, which has a motor-driven driver that is linearly movable away from the yarn path. The driver is attached to an endless belt.

[0010] 5 which is moved transversely to the yarn path. The driver deflects a yarn laterally from its yarn path to create an underfeed. Subsequently, the yarn is released from the driver at a deflection point located laterally to the yarn path to create the overfeed by abruptly ending the deflection of the chamfer. EP 3 246 438 A1 further discloses a generic

[0011] 10. Device in which the endless belt was replaced by a linearly moving back and forth driver.

[0012] US 4,368,612 discloses a device for deflecting a thread with a lever, wherein a pivoting movement of the lever deflects the thread from its path. The pivoting movement of the lever for deflecting the thread is achieved by a pneumatic cylinder with teeth that engage with mating teeth on a pivot axis to which the lever is attached. Once a predetermined deflection magnitude is reached, the cylinder is depressurized and the lever is pivoted back to its original position by a spring.

[0013] WO 2008 / 034457 A1 discloses a device in which a thread is carried over a

[0014] The thread guide edge is deflected. The thread guide edge is attached to the outside of a rotating body, which is moved along the thread path. The thread guide edge has at least one discontinuity to abruptly vary the deflection of the thread. A device of the same type is disclosed in JP 2010 053 498 A.

[0015] 25. A disadvantage of these known designs is that the yarn to be supplied is deflected by a carriage or lever, or a thread guide edge, and then released by it. However, if a high bulkiness is to be achieved, this requires a long pull of the gam from the original thread path. On the return to the original thread path, irregularities in the speed profile of the effect yarn occur at high production speeds, which affects the quality of the novelty yarn.

[0016] DE 40 11 458 A1 discloses a device for deflecting a thread using a rotating thread guide. The rotating thread guide is rotatably attached to a free end of a lever. The lever is rotated in a constant direction about a rotational axis, causing the rotating thread guide to move in a predetermined plane on a circular path. The movement of the rotating thread guide deflects the thread from its path and returns it to it. A disadvantage of this design is that changing the magnitude of the deflection requires replacing the lever or a pivot point of the rotating thread guide on the lever. In a device disclosed in US 4,080,777, the thread guide attached to a lever is moved via a cam. A disadvantage of this design is that changing the magnitude of the deflection requires replacing the cam.

[0017] The object of the present invention is therefore to provide a device and a method for supplying a gam for the production of an effect yarn, which enables under-delivery and over-delivery of the yarn with the smallest possible deflection of the yarn and thus a high quality and uniformity of the effect gam with a high production output.

[0018] The problem is solved by a device with the features of the independent claims. A device for guiding a gam for generating an effect gam is proposed, wherein the device comprises a control unit and at least three yarn guides fixed in a base plate, and the yarn guides are arranged one behind the other in a guide axis. The yarn guides are designed as open loops, pins, closed or slotted rings. A yarn guide element is provided between each of the fixed yarn guides, wherein the yarn guide elements are arranged in an element axis and attached to a pivoting element provided with a drive and held in a pivot axis, wherein in a basic position of the pivoting element the 4

[0019] The yarn guide axis is arranged in or parallel to the guide axis. The yarn guide elements are designed as cylindrical bolts, hook-like structures, rings, or in other designs known for guiding yarns. Due to the arrangement of the yarn guides and yarn guide elements, the yarn runs alternately over a yarn guide and along a yarn guide element, or through a yarn guide element. Yarn guides and yarn guide elements are advantageously made with a wear-resistant coating or entirely from a wear-resistant material, such as ceramic.

[0020] The pivot axis around which the pivoting element is pivoted must be arranged such that a home position is reached in which the yarn runs through the yarn guides without being deflected by the yarn guide elements. In this home position, the yarn runs along the guide axis through the device. The pivot axis can be arranged parallel to or at any angle to the guide axis. With a suitable design of the pivoting element, it is ensured that the axis formed by the yarn guide elements lies in the home position of the pivoting element at or parallel to the guide axis formed by the yarn guides.

[0021] Because, in the pivoting element's home position, the element axis with the yarn guide elements is arranged in or parallel to the guide axis equipped with the yarn guides, the yarn runs along the guide axis without deflection due to the yarn guides and the yarn guide elements. When the pivoting element is now pivoted by the drive, the element axis with the yarn guide elements is moved from its home position, thus lengthening the path the yarn travels from one yarn guide to the next. Accordingly, a pivoting movement of the pivoting element causes the chamois to be delivered too far. After reaching its maximum deflection, the drive returns the pivoting element to its home position, thus achieving an over-delivery of the chamois. 08 / 08 / 2025

[0022] P14524WO

[0023] 5

[0024] The yarn guides, at least two in number, deflect the yarn at two points as soon as the pivoting element leaves its home position. These two simultaneous deflections allow for smaller deflections, resulting in an equivalent lengthening of the yarn path and thus a corresponding length compared to a single deflection.

[0025] 5 of the transmission process. In this way, a small pivoting motion is required, which allows for an increased frequency of pivoting movements and consequently an increase in the production of effect yarn. At the same time, the yarn movement is stabilized and vibrations of the chamfer during transmission are avoided.

[0026] 10 In an alternative application of the device, for example, a first yarn runs through the first and second yarn guide elements, and a second yarn runs through the second yarn guide element. The yarns also pass through the yarn guides between which the yarn guide elements assigned to each yarn are located. This causes both yarns to be deflected simultaneously by the pivoting movement of the pivoting element, but not by the same amount. The magnitude of the deflection depends on the arrangement of the yarn guides and the yarn guide elements, as well as the number of yarn guide elements that each yarn passes through. This application makes it possible to generate two effect games simultaneously, with the resulting effects being used for the

[0027] 20 Both games are not the same.

[0028] Advantageously, the pivoting element is held as a pivot arm in a pivot axis arranged perpendicular to the guide axis and attached to the base plate. Designing the pivoting element as a pivot arm minimizes the mass of the pivoting element that must be moved by the drive and enables

[0029] 25 light a dynamically stable design of the swivel element. Due to the perpendicular arrangement of the swivel axis on the guide axis, the largest possible deflections of the yarn guide elements relative to the fixed yarn guides result during a swivel movement of the swivel arm. Attaching the swivel axis, and thus also the swivel arm, to the base plate results in a compact

[0030] 30. Construction of the device. This allows the device to be constructed as a single unit using simple 6.

[0031] It can be easily installed in or removed from a textile machine. Furthermore, compared to a separate bracket for the swivel axis on the base plate, the necessary adjustments to achieve the swivel arm's home position relative to the guide axis formed by the arrangement of the yarn guides on the base plate are eliminated.

[0032] As an alternative to a swivel arm, the swivel element can be configured as a swivel disc mounted on a pivot axis perpendicular to the guide axis and attached to the base plate. Designing the swivel element as a swivel disc allows for an increase in the number of yarn guides without altering the symmetry of the swivel element's mass on the pivot axis. The yarn guides and guide elements are arranged on both sides of the pivot axis. Advantageously, one axis of the swivel disc is located along the pivot axis. The swivel movement corresponds to a rotational movement of the swivel disc, whereby the yarn guide elements on one side of the pivot axis move away from the guide axis in one direction, and those on the other side move away from the guide axis in the opposite direction.

[0033] In another embodiment of the swivel disc, the yarn guide elements on one side of the swivel axis are arranged at an angle to the yarn guide elements on the opposite side of the swivel axis. On one side of the swivel axis, a first yarn is guided through the yarn guide elements, and on the opposite side of the swivel axis, a second yarn is guided through the yarn guide elements. When the swivel disc swivels, the angled offset causes either the first or the second yarn to deflect. The home position for the yarn guides on one side of the swivel axis corresponds to a deflected position of the yarn guide elements on the opposite side. Thus, it is always either the axis of one yarn guide element or the axis of the opposite one that is deflected. (08.08.2025)

[0034] P14524WO

[0036] Yarn guide elements parallel to the guide axis of the respective chamois. The swivel disc never reaches a state in which none of the yarns are deflected.

[0037] Preferably, the yarn guide elements are in a closed, ring-shaped

[0038] 5. Design. Due to the arrangement of the yarn guides and yarn guide elements, the yarn alternately passes through a yarn guide and a closed yarn guide element. The yarn guides are particularly preferably designed in a closed, ring-shaped construction. This has the advantage that even with vibrations of the running yarn, no snagging or threading of the yarn from the yarn guides can occur. A closed, ring-shaped yarn guide, as well as a closed, ring-shaped yarn guide element, is designed, for example, as a single ring or as a combination of two open rings. In a design consisting of several open rings, the openings of the individual rings do not overlap, so that in the overall arrangement of the several open rings

[0039] Fifteen rings form a closed ring. This type of construction allows yarn to be threaded between the partially open rings without having to be pulled through a single, closed ring. Yarn guides and yarn guide elements are advantageously made with a wear-resistant coating or entirely from a wear-resistant material, such as ceramic.

[0040] 20. By designing the yarn guide elements as closed rings, the yarn is guided at all times in every position of the pivoting element and during its pivoting movement. The yarn does not need to be caught by an open guide for a subsequent pivoting movement, which on the one hand allows for a controlled change in the direction of the pivoting movement and on the other hand prevents the transmission of vibrations or after-oscillation of the yarn, even at short intervals or during interval changes. After reaching a maximum deflection of the pivoting element, it is returned to its home position by the drive, thus ensuring the yarn is passed through. Subsequently, the pivoting element can be pivoted in the opposite direction, which allows the

[0041] 30 has the same effect on the path to be traveled by the yarn, whereby the 08.08.2025

[0042] P14524WO

[0044] The pivoting element cannot be stopped in its home position. Because of this possible deflection of the pivoting element in both directions, without interrupting the pivoting movement between deflections, a short transmission interval can be achieved.

[0045] Preferably, the yarn guides and yarn guide elements are designed as closed rings with ceramic wear protection. Simple closed rings have proven advantageous compared to closed rings composed of several open rings. This simplifies the design of the ceramic wear protection. The resulting increased durability of the yarn guides and yarn guide elements outweighs the slightly more complex threading technique.

[0046] Preferably, the drive is mounted on the base plate and is designed as a frequency-controlled stepper motor with a motor shaft, the motor shaft corresponding to the pivot axis. Mounting the drive to the base plate completes the device as a single unit. Modern stepper motor designs allow for high frequencies of pivoting movements. Furthermore, the speed and magnitude of each individual movement of the motor shaft can be controlled. Using the motor shaft as the pivot axis eliminates the need for force redirection, for example, through a gearbox, resulting in reduced wear on the drive and backlash-free movement of the pivoting element. Additionally, the drive has a lower mass to move.

[0047] Advantageously, a first pivot angle is formed during a pivoting movement of the pivoting element in a first direction between the element axis and the guide axis, and a second pivot angle is formed during a pivoting movement of the pivoting arm in a second direction opposite to the first direction between the element axis and the guide axis. Distinguishing between the pivoting movements from the home position in a first direction and in a second direction allows for the possibility of asymmetry. Thus, the first 08.08.2025

[0048] P14524WO

[0049] 9

[0050] The first swivel angle, for example, may be fifty percent larger than the second swivel angle, resulting in a different transmission of the chamois and enabling a wide variety of patterns in the finished product.

[0051] Preferably, the swivel angles are limited by a stop for the swivel arm provided on the base plate. This mechanical limitation allows for simple calibration of the stepper motor. Approaching the stop resets the stepper motor. The mechanical limitation of the swivel angle also contributes to the safety of the device. By limiting the swivel angle and thus mechanically defining a maximum deflection of the swivel arm, it is prevented that in the event of damage to the drive, such as the motor or gearbox, or to the mounting of the swivel element on the swivel axis, the swivel element would be deflected too far and thereby damage surrounding components of the device.In a further development of the device, the stops for the swivel element are equipped with a sensor which triggers a shutdown of the drive when the swivel element comes into contact with the stop.

[0052] Furthermore, it is advantageous if the maximum swivel angles are less than 60 degrees, preferably 45 degrees. Excessive swivel angles lead to design difficulties. To prevent instability of the yarn running through the yarn guides and yarn guide elements at very large swivel angles, a swivel element with a correspondingly long extension along the element axis and a large number of yarn guide elements must be provided. It has been shown that a compact design can be achieved with a maximum swivel angle of 60 degrees.

[0053] Preferably, the control system predefines the swivel angle for each swivel movement in every direction. Because the control system determines a separate swivel angle for each swivel movement, the possibilities for designing patterns in the final product are increased many times over. August 8, 2025

[0054] P14524WO

[0055] 10

[0056] The swivel angle can also have a different magnitude for one swivel movement than for the subsequent swivel movement in the same direction.

[0057] Advantageously, the control system allows for up to 3,000 individual swivel movements per minute. Since the drive does not need to change direction between swivel movements in the first direction and a subsequent swivel movement in the second, a faster sequence of transmissions is possible than with known devices of this type. Due to the described operating principle of the device, it is advantageous if the swivel movements alternate between the first and second directions.

[0058] In a further development, the device for guiding two yarns is provided for the production of two effect yarns. The device has at least three yarn guides for each yarn to be guided, which are fixed in a base plate. The yarn guides are arranged one behind the other along a guide axis, and the yarn guide elements provided between the fixed yarn guides are arranged with their element axis between the guide axes. The yarn guide elements are designed as drivers, advantageously in a cylindrical form, so that during a pivoting movement from the home position in the first direction, they deflect one yarn, and during a pivoting movement from the home position in the second direction, they deflect the other yarn. In this way, only a single device is necessary to produce two effect yarns.

[0059] If the pivoting element is designed as a pivoting arm, one yarn is deflected during a pivoting movement from the home position in the first direction, and the other yarn is deflected during a pivoting movement from the home position in the second direction. The size, speed, and timing of each pivoting movement are determined by the control system. This also allows for multiple pivoting movements in the same direction before a pivoting movement in the opposite direction is executed. If the pivoting element is designed as a pivoting disc, simultaneous deflection of both yarns is possible when the yarn guide elements are arranged on both sides of the pivot axis.

[0060] Particularly preferred are four stationary yarn guides and a total of three yarn guide elements arranged between the stationary yarn guides on the pivoting element. It has been shown that this number of yarn guides and yarn guide elements optimizes the balance between the extension of the pivoting element and the lengthening path of the yarn during pivoting movements. During operation, the yarn is deflected from the guide axis at three points by the three yarn guide elements, resulting in high delivery even at small pivoting angles.

[0061] In a further development, one or more yarn guide elements are held in a sliding ring. The sliding ring, in turn, is movably mounted on the swivel disc and can be rotated around the swivel disc's axis, and thus around the pivot axis, independently of any movement of the swivel disc. This makes it possible to adjust the distance between the yarn guide elements and the guide axis and to influence the magnitude of the yarn deflection during a swivel movement. The sliding ring can be coupled to an additional drive. In this way, a dynamic change in the yarn feed from one swivel movement to the next can be achieved. When a swivel movement is combined with a displacement of the sliding ring, it can be ensured that a yarn guide element is not moved away from the guide axis, even when the swivel disc itself is swiveling.The corresponding yarn guide element becomes ineffective and contributes nothing to a deflection of the corresponding yarn. Furthermore, it is advantageous if, in a swivel element design as a swivel disc in a device for guiding two yarns, the yarn guide elements are provided with a geometry of cylindrical bolts of different lengths. The yarn guides are arranged at different distances from the swivel disc, so that, for example, a yarn does not pass through all yarn guide elements, but only through the longer ones.

[0062] The yarn guide elements are deflected. Meanwhile, the second yarn is deflected by all the yarn guide elements used during a pivoting movement.

[0063] Furthermore, a textile machine for the production of fantasy yarns is proposed, in which a device as described above is provided and its control is integrated into a central control system of the textile machine. Integrating the device's control into the central control system of the textile machine allows for a simplification of the device and enables operation of the device and input of parameters, such as swivel angle or number of swivel movements per unit of time, via a control panel of the textile machine.

[0064] Furthermore, a method for guiding at least one yarn for the production of an effect yarn is proposed, comprising a device with a control unit and at least three yarn guides fixed in a base plate, the yarn guides being arranged one behind the other in a guide axis. A yarn guide element is provided between each of the fixed yarn guides, the yarn guide elements being arranged in an element axis and attached to a pivoting element equipped with a drive and held in a pivot axis. In a home position, the element axis is arranged in or parallel to the guide axis, and the pivoting element is moved by the drive in a pivoting motion about the pivot axis from the home position and then returned to the home position.The pivoting movement moves the yarn guide elements away from the guide axis, so that the yarn path of the chamfer, determined by the yarn guides and the yarn guide elements, is lengthened and the chamfer is passed over when the pivoting element is swung back into the basic position.

[0065] It is advantageous if the pivoting element pivots from the home position in a first direction by a first pivoting angle resulting between the element axis and the guide axis, and then via the home position in a second direction opposite to the first direction by a 08.08.2025

[0066] P14524WO

[0067] 13. The second pivoting angle is achieved between the element axis and the guide axis. Due to this possible deflection of the pivoting element on both sides, a short interval between the transmissions can be achieved. However, it is also still possible for there to be an inconsistency between individual transmissions.

[0068] 5. Break in the rotation. Furthermore, differentiating the swivel angles according to the direction of the swivel movement leads to the greatest possible freedom in the design of the effect game.

[0069] Preferably, yarn patterns are generated by the control system through one or more of the following control interventions:

[0070] 10 - changing the swivel angle leads to a change in the size of the under-delivery or over-delivery of yarn;

[0071] - varying the speed of the swiveling movement, thereby achieving a speed at which the under-delivery or the over-delivery is formed;

[0072] - varying the waiting time between pivoting movements, thus the sub-deliveries and over-deliveries are not formed in direct succession;

[0073] - repeating the same swivel angle creates uniform or at least sectionally uniform patterns;

[0074] - repeating a sequence of unequal swivel angles;

[0075] 20 - repeat variations of the speeds of the swivel movements;

[0076] - repeating a sequence of variations in the speed of the swivel movements.

[0077] By repeating sequences and variations, pattern changes are generated in a given repeating sequence.

The drive element 19 is connected to the swivel arm 10, which is mounted in the pivot axis 12. With the aid of the drive 16, the swivel arm 10 is moved in a first direction 14 by a pivoting movement 13, thereby creating a first contact between the guide axis 6 and the element axis 9.

[0117] 10. Swivel arm 10 is pivoted by the drive 16 back to its home position and then pivoted in a second direction 15, resulting in a second pivot angle β between the guide axis 6 and the element axis 9. Due to the arrangement of the pivot axis 12 in the guide axis 6 in the home position, pivoting movements 13 in the first direction 14 and in the second direction 15, with identical first pivot angles α and second pivot angles β, result in identical path extensions for a yarn running through the yarn guides 5 and the yarn guide element 8 (shown only in the pivoted state 25), regardless of the direction of the pivoting movement 13. This allows for the halving of an interval in a production process.

[0118] 20. The use of traditional methods allows for a significantly higher production speed. To execute and define parameters of the swivel movements 13, such as speeds or swivel angles a and ß, the drive 16 is connected to a control unit 3, which is shown as an example outside the device.

[0119] Figures 6a and 6b show a schematic representation of a fourth embodiment of a device according to the invention. The device shown makes it possible to produce two effect yarns. The device has a base plate 4. Three closed, ring-shaped yarn guides 5 for a first yarn 1 and three closed, ring-shaped yarn guides 5 for a second yarn 2 are fixedly attached to the base plate 4.

[0122] 18 a guide axis 6 and a guide axis 7 is formed by connecting the three yarn guides 5 intended for a second yarn 2. Furthermore, a pivot arm 10 is held on the base plate 4 in a pivot axis 12. In the embodiment shown, the pivot axis 12 is perpendicular to the guide axes 6.

[0123] 5 and 7 are arranged. A yarn guide element 8 in the form of a cylindrical bolt is attached to the swivel arm 10 between each of the yarn guides 5. In Figure 6a, the swivel arm 10 is shown in a basic position and additionally in a first, flexed state 25, shown in dashed lines. In Figure 6b, the swivel arm 10 is shown in the basic position and additionally in a second, flexed state, shown in dashed lines.

[0124] 10 swivel state 26 is shown. In the basic position of the swivel arm 10, an element axis 9 formed by the yarn guide elements 8 is arranged parallel to the guide axes 6 and 7 and between the guide axes 6 and 7.

[0125] Furthermore, a drive 16 is shown, which has a motor shaft 18 and a drive element 19, for example a belt drive. The drive element 19 is connected to the pivot arm 10, which is mounted in the pivot axis 12. With the aid of the drive 16, the pivot arm 10 is moved in a first direction 14 with a pivoting movement 13, resulting in a first pivot angle α between the guide axis 6 and the element axis 9, which leads to the first wasted state 25. A dotted line shows the course of the first game 1 in wasted state 25.

[0126] Figure 20 of the swivel arm 10 is shown, illustrating that the distance traveled by the first yarn 1 between the yarn guides 5 in a waste state 25 of the swivel arm 10 is greater than in the swivel arm 10's home position. With the aid of the drive 16, the swivel arm 10 is moved in a second direction 15 with a pivoting motion 13, resulting in a second pivot angle β between the guide axis 7 and the element axis 9, leading to the second waste state 26. A dotted line shows the path of the second yarn 2 in the waste state 26 of the swivel arm 10, illustrating that the distance traveled by the second yarn 2 between the yarn guides 5 in a waste state 26 of the swivel arm 10 is greater.

[0130] Pivoting movement 13 in the second direction 15 deflects the second yarn 1 from its home position. This arrangement of the yarn guides 5 and the yarn guide elements 8 enables the same device to feed two yarns 1 and 2. To execute and define the parameters of the pivoting movements 13,

[0131] 5 such as speeds or swivel angles a and ß, the drive 16 is connected to a control 3, which is shown by way of example outside the device.

[0132] Figure 1 shows a schematic representation of a fifth embodiment of a device according to the invention, and Figure 8 shows a schematic top view from direction C according to Figure 7. The device has a base plate 4. Three closed, annular yarn guides 5 are fixedly attached to the base plate 4. A guide axis 6 is formed by connecting the yarn guides 5. A pivot arm 10 is also held on the base plate 4 in a pivot axis 12.

[0133] In the illustrated embodiment, the pivot axis 12 is arranged parallel to the guide axis 6. A closed, annular yarn guide element 8 is attached to the pivot arm 10 between each yarn guide 5. Due to the arrangement of the pivot arm 10, a yarn passage 22 is provided in the base plate 4, lying in the guide axis 6. Figures 7 and 8 show the pivot arm 10 in a home position, and Figure 8 additionally shows the pivot arm 10 in a first waste state 25 and a second waste state 26 (shown in dashed lines). In the home position of the pivot arm 10, an element axis 9 formed by the yarn guide element 8 is arranged in the guide axis 6. However, in the waste states 25 and 26 of the pivot arm 10, the element axis 9 deviates from the guide axis 6.A connecting line arranged perpendicular to the pivot axis 12 to the yarn guide element 8 held on the pivot arm 10 forms the pivot arm axis 27.

[0134] Furthermore, a drive 16 is shown, which is held by way of example on the base plate 4 by means of fastenings 17. The drive 16 has a motor shaft 18 which is arranged in the pivot axis 12. The motor shaft 18 is connected to the pivot arm 10.

[0138] The pivoting movement 13 moves in a first direction 14, resulting in a first pivoting angle α between the pivot arm axis 27 in the home position and the pivot arm axis 27 in the first wasted state 25. Subsequently, the pivot arm 10 is returned to the home position by the drive 16 and beyond.

[0139] The pivot arm 5 is pivoted in a second direction 15, resulting in a second pivot angle β between the pivot arm axis 27 in the home position and the pivot arm axis 27 in the second pivoted state 26. Due to the parallel arrangement of the pivot axis 12 to the guide axis 6, pivot movements 13 in the first direction 14 and in the second direction 15 with identical first pivot angle α and second pivot angle β result in identical path extensions for a yarn (not shown) running through the yarn guides 5 and the yarn guide elements 8, regardless of the direction of the pivot movement 13. This allows for halving an interval in the production of transmissions, thereby achieving a significantly higher production speed.

[0140] 15 For the execution and determination of parameters of the swivel movements 13, such as speeds or swivel angles a and ß, the drive 16 is connected to a control 3, which is shown by way of example outside the device.

A yarn passage 22 is provided in the base plate 4 outside the yarn guides 5, so that a yarn 1 can be guided out of the device in the guide axis 6. Furthermore, a pivot element in the form of a pivot arm 10 is held on the base plate 4 in a pivot axis 12. In the embodiment shown, the pivot axis 12 is arranged perpendicular to the guide axis 6. Three yarn guide elements 8 are attached to the pivot arm 10. The yarn guide elements 8 are each

[0143] 30 arranged between two yarn guides 5. In Figures 9 and 10, the swivel arm 10 is shown in a basic position, and in Figure 10, the swivel arm 10 is additionally shown. 08.08.2025

In the home position of the swivel arm 10, an element axis 9 formed by the yarn guide elements 8 is arranged in the guide axis 6. However, in a waste state 25 or 26 of the swivel arm 10, the element axis 9 deviates from the guide axis 6. A dotted line shows the path of the yarn 1 in the waste state 25 of the swivel arm 10, illustrating that the distance traveled by the yarn 1 between the yarn guides 5 in a waste state 25 or 26 of the swivel arm 10 is greater than in the home position of the swivel arm 10.

[0146] Furthermore, a drive 16 is shown, which is held by means of fasteners 17 on the base plate 4. The drive 16 has a motor shaft 15. The drive 16 is connected to the swivel arm 10 via the motor shaft 18. With the aid of the drive 16, the swivel arm 10 is moved by a pivoting motion 13 in a first direction 14, resulting in a first pivot angle α between the guide axis 6 and the element axis 9. Subsequently, the drive 16 pivots the swivel arm 10 back to its home position and beyond, in a second direction 15, resulting in a second pivot angle β between the guide axis 6 and the element axis 9.Due to the perpendicular arrangement of the pivot axis 12 on the guide axis 6, pivoting movements 13 in the first direction 14 and in the second direction 15 result in identical path lengths for the yarn 1, regardless of the direction of the pivoting movement 13, with identical first pivot angle a and second pivot angle β. This allows for a halving of an interval in the production of transmissions, thereby achieving a significantly higher production speed.

[0147] To execute and define parameters of the pivoting movements 13, such as speeds or pivot angles a and β, the drive 16 is connected to a control unit 3, which is shown by way of example outside the device. Furthermore, a first stop 20 is provided for the mechanical limitation of the pivoting movement 13 in the first direction 14, and a second stop 20 is provided for the mechanical limitation of the rotation.

Furthermore, a pivot element in the form of a swivel disc 11 is held on the base plate 4 in a pivot axis 12. In the embodiment shown, the pivot axis 12 is arranged perpendicular to the guide axis 6. Four cylindrical yarn guide elements 8 are attached to the swivel disc 11. The yarn guide elements 8 are each arranged between two yarn guides 5. In Figure 11 and Figure

[0153] Figure 15 shows the swivel disc 11 in a home position, and in Figure 12 the swivel disc 11 is additionally shown in a dashed line in a waste state 25. In the home position of the swivel disc 11, an element axis 9 formed by the yarn guide elements 8 is arranged parallel to the guide axis 6. In the waste state 25 of the swivel disc 11, however, the element axis 9 deviates from the guide axis 6.

[0154] The pivot axis 9 deviates from its parallelism to the guide axis 6. A dotted line shows the path of the yarn 1 in the slack state 25 of the swivel disc 11, illustrating that the distance traveled by the yarn 1 between the yarn guides 5 in a slack state 25 of the swivel disc 11 is greater than in the basic position of the swivel disc 11. By designing the swivel element as a swivel disc 11, a large number of yarn guide elements 8 can be accommodated with a low overall height by means of a central arrangement of the swivel disc 11 on the pivot axis 12.

[0160] 5 of the parameters of the swivel movements 13, such as speeds or swivel angles a and ß, the drive 16 is connected to a control 3, which is shown by way of example outside the device.

[0161] Figure 13 shows a schematic representation of an eighth embodiment of a device according to the invention. The device shown makes it possible to produce two effect yarns. The device has a base plate 4. Five closed, annular yarn guides 5 for a first yarn 1 and five closed, annular yarn guides 5 for a second yarn 2 are fixedly attached to the base plate 4. A guide axis 6 is formed by connecting the five yarn guides 5 for a first yarn 1, and a guide axis 7 is formed by connecting the five yarn guides 5 for a second yarn 2. A pivoting disc 11 is also held on the base plate 4 in a pivot axis 12. In the embodiment shown, the pivot axis 12 is arranged perpendicular to the guide axes 6 and 7. A yarn guide element 8 in the form of a cylindrical bolt is attached to the pivoting disc 11 between each of the yarn guides 5.Figure 13 shows the swivel arm 10 in a home position and additionally, in dashed lines, in a first waste state 25 and a second waste state 26. In the home position of the swivel disc 11, an element axis 9 formed by the yarn guide elements 8 is arranged parallel to and between the guide axes 6 and 7.

[0162] Furthermore, a drive 16 is shown, which is arranged in the pivot axis 12 and connected to the swivel disk 11 mounted in the pivot axis 12.

[0166] Yarn guide elements 8 deflect the first yarn 1 and the second yarn 1 is deflected by the yarn guide elements 8 located below the pivot axis 12. A dotted line each shows the path of the first yarn 1 and the second yarn 2 in the wasted state 25 of the pivot disc 11, thus clarifying

[0167] 5, the distance traveled by the first yarn 1 and the second yarn 2 between the yarn guides 5 in a waste state 25 of the swivel disc 11 is greater than in the swivel disc 11's home position. With the aid of the drive 16, the swivel disc 11 is moved in a second direction 15 with a pivoting motion 13, resulting in a second pivot angle β between the guide axis 7 and the element axis 9, which leads to the second waste state 26. The pivoting motion 13 in the first direction 14 deflects both yarns 1 and 2 from their home positions, and the pivoting motion 13 in the second direction 15 also deflects both yarns 1 and 2 from their home positions. This arrangement of the yarn guides 5 and the yarn guide elements 8, in combination with a swivel disc 11, enables the simultaneous delivery of two yarns 1 and 2 with the same device.

In Figures 14 and 15, the pivot disc 11 is shown in a basic position, and in Figure 12, the pivot disc 11 is additionally shown in a dashed line in a slack state 25. In the basic position of the pivot disc 11, an element axis 9 formed by the yarn guide elements 8 is arranged parallel to the guide axis 7. In the slack state 25 of the pivot disc 11, however, the element axis 9 deviates from its parallelism to the guide axis 7 and is parallel to the guide axis 6. A dotted line indicates the path of the first game 1 in each case.
