[0001] Texturing unit, textile machine and method for texturing
[0002] The present invention relates to a texturing unit for a textile machine, comprising a heating device for heating at least one thermoplastic thread, a twist unit for introducing a twist into the at least one thread, and at least one twist stop element for stopping the twist. Furthermore, the invention relates to a textile machine and a method for texturing at least one thermoplastic thread.
[0003] EP 0 777 002 A2 discloses a device for producing a textured composite yarn comprising at least two threads. A disadvantage of this device is that the two threads are already significantly cooled by the ambient air upon meeting at a meeting point. Furthermore, the texturing zone is shortened and / or the machine dimensions are increased. Furthermore, the meeting of the two threads with a large angular offset and / or a yarn stop element arranged at the meeting point can result in damage to at least one of the threads. The yarn quality, particularly in microfilaments, can be impaired by mechanical influences, for example, by known yarn stop elements.
[0004] The object of the present invention is to eliminate the disadvantages known from the prior art.
[0005] The problem is solved by a texturing unit, a textile machine, and / or a texturing method having the features of the independent patent claims. A texturing unit for a textile machine is proposed, comprising a heating device for heating at least one thermoplastic thread, a twist unit for introducing a twist into the at least one thread, and at least one twist stop element for stopping the twist. The textile machine is preferably a texturing machine and / or a spinning machine.
[0006] In texturing machines, several texturing units are usually arranged side by side. Each of the texturing units is designed to process or produce crimped textile threads. The texturing units can perform the false twist process. During intended use of the texturing unit, the at least one thread is heated, drawn, and / or twisted or twisted. Preferably, the threads are additionally cooled. This textures the at least one thermoplastic thread, forming crimped threads. The heating device heats the at least one thread. The twisting unit twists the at least one thread or introduces a twist into the at least one thread.
[0007] If the textile machine is designed as a spinning machine, the texturing unit according to the invention can be connected to at least one spinning unit, so that, for example, the thread produced with the aid of the spinning unit is textured with the aid of the texturing unit.
[0008] A thread or thermoplastic thread can be understood to mean a straight or smooth thread. These are usually smooth filaments to which a crimped structure is to be given with the help of the texturing unit. Several smooth filaments can also form a thread. Furthermore, as is known from the prior art, several threads can be twisted together. The at least one thread can also be called filament yarn. By twisting the at least one thread, a textured thread or a textured yarn is formed. To prevent the twist of the thread from being introduced to an input feed mechanism of the texturing unit, the texturing unit has the twist stop element. With the help of the twist stop element, a texturing zone in which the twist acts on the at least one thread can be reduced. The texturing zone is the zone or the length between the twist unit and the twist stop element.In the texturing zone, the yarn is textured due to the effect of the twist. By reducing the texturing zone with the help of the twist stop element, the delivery speed, or what is known as the surging speed, can be increased. Above the "surging speed," the yarn would or could balloon, causing the yarn tension to become unstable. By increasing the "surging speed," a stable texturing process can be ensured even at high delivery speeds.
[0009] According to the invention, the at least one twist stop element is arranged on and / or within the heating device. In the prior art, twist stop elements are usually arranged outside, in particular in front of the heating device. The at least one thread reaches its maximum temperature inside and / or on the heating device. By arranging the twist stop element on and / or within the heating device, the thread can thus be twisted at the maximum temperature or a maximum twist can be exerted on the at least one thread. In this way, the greatest possible crimp of the thread can be generated. In addition, this makes it possible to create a texturing unit that is as compact as possible since, among other things, the twist stop element does not require any additional installation space or space along a conveying direction.
[0010] Advantageously, the texturing unit comprises a cooling device for cooling the at least one thread, wherein the cooling device is preferably arranged between the heating device and the twisting unit along a conveying direction of the thread. Thus, after the at least one thread has been heated, the cooling can be carried out. With the aid of the cooling device, the cooling of the at least one thread takes place more quickly than with the aid of the ambient air, whereby the texturing unit or its length in the conveying direction can be designed more compactly. Furthermore, the targeted heating and cooling allows the texturing process to be operated more stably, since the heating and cooling can be specifically adjusted.
[0011] It is advantageous if the heating device comprises at least one heating element extending at least partially along a conveying direction of the at least one thread and / or at least one heated godet. A heating element is understood to be an element past or through which the thread moves and is thereby heated and / or warmed. Since the heating element extends at least partially along the conveying direction, the thread is continuously heated along the conveying direction. Preferably, the heating element is uninterrupted or uninterrupted along the conveying direction. The heating element can, for example, comprise at least one heating rail that heats the at least one thread. Godets are often used to convey or transport the thread along the conveying direction. The thread can also be heated with the help of the at least one heated godet.
[0012] The twist stop element is preferably arranged on the at least one heating element, within the at least one heating element, on the at least one heated godet, between the heating element and the at least one heated godet, and / or between two of the heated godets. The twist stop element can, for example, be arranged directly on the at least one heating element, within the at least one heating element, on the at least one heated godet, between the heating element and the at least one heated godet, and / or between two of the heated godets. This improves the compact design of the texturing unit. In addition, the twist stop element can be mounted and / or connected to the heating device, in particular to the heating element. This eliminates the need for an additional bearing element. This also allows the texturing zone to be further shortened. Furthermore, the thread can be heated as a smooth thread, which results in better or more even texturing.higher heat input can be created.
[0013] It is also advantageous if the at least one twist stop element is arranged in the region of a thread outlet, in the region of a thread inlet, between the thread inlet and the thread outlet and / or within at least one groove of the at least one heating element and / or the at least one heated godet. The heating element is preferably designed as a one-piece heating element, within which the at least one thread can be guided, in particular with the aid of the at least one groove. Similarly, the at least one groove can be arranged on the surface of the at least one heated godet. For example, the at least one heating rail can be arranged on both sides or one side of the at least one groove. In this way, the thread can be heated or warmed up continuously. The thread inlet and the thread outlet are preferably the respective openings of the groove along the conveying direction for the thread.If the at least one groove is arranged on the at least one heated godet, the thread outlet and / or the thread inlet is designed, for example, as a circumferential opening of the groove.
[0014] If the at least one twist stop element is arranged in the region of the yarn outlet, the texturing zone is as short as possible. With the short texturing zone, the delivery speed can be increased, as already described above. In addition, the crimping effect can be increased by arranging the twist stop element in the region of the yarn outlet, since a very high yarn temperature can be achieved there. It is also conceivable for the twist stop element to extend along the conveying direction from the yarn inlet to the yarn outlet. It is also advantageous if the twist stop element is arranged in the region of a high-temperature section of the at least one heating element and / or the heated godet or of the at least one yarn in the at least one heating element and / or on the at least one heated godet and / or is arranged upstream of the high-temperature section along the conveying direction.The high-temperature section is understood to be the section and / or point within the heating device, in particular within the at least one heating element and / or on the at least one heated godet roll, at which the temperature of the thread or the thread temperature is at its highest or maximum. Since the twist is introduced by the twist unit, which is arranged downstream of the heating device along the conveying direction, the twist from the twist unit acts on the at least one thread against the conveying direction up to the twist stop element. In order to achieve the highest possible crimp of the at least one thread, the twist should act on the at least one thread in the region of the high-temperature section. The above-mentioned arrangement of the twist stop element in the region of the high-temperature section and / or upstream of the high-temperature section thus leads to very high crimp of the at least one thread.
[0015] The high-temperature section is preferably located in the region of the last third of the at least one groove and / or spaced from the yarn outlet. The last third of the groove extends from the yarn outlet opposite the conveying direction of the at least one heating element and / or the at least one heated godet. Thus, the texturing zone or texturing section can be designed or shortened as short as possible.
[0016] The production speed can be increased by making the texturing zone as short as possible. Additionally or alternatively, the highest possible yarn temperature can be achieved in the twisted / twisted state of the yarn. This leads to high crimp in the yarn. Increasing the production speed can result in further advantages of the invention. Due to the increased production speed, it is conceivable for the texturing unit to be arranged in and / or downstream of the spinning unit and / or several spinning units of the textile machine designed as a spinning machine. The production of at least one yarn in the spinning unit usually takes place at a very high production speed. By shortening the texturing section and / or increasing the production speed of the texturing unit, the two production speeds of the spinning unit and the texturing unit can be brought closer to one another.
[0017] It is also advantageous if the at least one twist-stop element is designed as a pin and / or as a partition. A pin is understood to be an element that has a constant cross-section along a vertical direction. For example, the pin can be cylindrical. When the at least one thread is conveyed, it rests at least partially on the outer surface of the pin. In this way, the twist can be reduced and / or stopped as gently as possible. A partition is understood to be an element that is elongated along the conveying direction and against which the thread rests at least partially during conveyance. The twist can also be gently reduced in this way. Additionally or alternatively, the at least one twist-stop element designed as a partition and / or pin can be used to separate several threads from one another and / or from the thread to a part of the heating element.
[0018] It is advantageous if the twist-stop element has a circular, semicircular, elliptical, and / or angular cross-section and / or a circular, semicircular, elliptical, or angular end. If the at least one twist-stop element is designed as a pin, for example, it advantageously has the circular, semicircular, elliptical, or angular cross-section. If the at least one twist-stop element is designed as a partition, for example, it advantageously has the circular, semicircular, elliptical, or angular end. The end of the partition is to be understood as the component of the partition that last acts on the at least one thread along the conveying direction. This allows the stopping and / or reduction of the twist in the thread and / or the separation to take place very gently.It is also conceivable for the partition to have a circular, semicircular, elliptical, or angular cross-section. For example, the partition can extend along the conveying direction with a constant cross-section. This allows the path of at least one thread in the heating element or within the groove to be modified.
[0019] Furthermore, it is advantageous if the twist-stopping element, designed as a dividing wall, extends along the conveying direction from the yarn inlet to the yarn outlet or ends within the at least one heating element and / or the at least one heated godet. Along the conveying direction, the end of the dividing wall is the component of the dividing wall that stops and / or reduces the twist. Thus, the twist is stopped following the high-temperature section. Because the twist acts on the at least one yarn in the region of the high-temperature section, maximum crimping of the at least one yarn can be achieved.
[0020] It is also advantageous if the twist stop element is made of a wear-resistant, corrosion-resistant and / or high-temperature-resistant material, in particular ceramic, steel and / or chromium, and / or is coated with such a material. During operation of the texturing unit, the at least one thread acts on the twist stop element, so that wear phenomena can occur here. Additionally or alternatively, by arranging the twist stop element within and / or on the heating device, a corrosion-resistant and / or high-temperature-resistant material results in a longer service life. It is also advantageous if the heating device comprises the at least one heated godet. The at least one heating element is preferably arranged downstream of the at least one heated godet along the conveying direction.By arranging at least one heated godet and at least one heating element in series, the yarn can be preheated before entering the heating element. This allows the heating element to be shortened and / or simplified. This leads to a reduction in the heating length extending along the conveying direction and thus to a more compact texturing unit. Additionally or alternatively, this can increase production speed. If at least two yarns are textured using the texturing unit, different temperatures can be applied to the yarns very easily using multiple heated godets.
[0021] Furthermore, it is advantageous if the texturing unit comprises at least one thread guide arranged upstream of the at least one heating element within the heating device and / or along the conveying direction, wherein the at least one thread guide is preferably arranged along the conveying direction between the at least one heated godet and the at least one heating element. In this way, the at least one thread can be guided or deflected within the heating device, in particular from the heated godet to the heating element. In this way, the texturing unit can be made more compact. Additionally or alternatively, a higher conveying speed of the at least one thread is possible. In this way, several threads can also be guided with the aid of the thread guides in such a way that mutual contact is avoided.
[0022] Furthermore, it is advantageous if the texturing unit comprises at least two twist-stop elements arranged in a row and / or spaced apart from one another along the conveying direction. As a result, the at least two twist-stop elements, in particular designed as pins, can separate several threads from one another as a common partition. It is also conceivable for twist-stop elements designed as pins and / or as a partition to be arranged in a row.
[0023] It is also advantageous if the heating device comprises at least two of the heated godets, at least two of the heating elements, the at least one heated godet with at least two of the grooves and / or the at least one heating element with at least two of the grooves, so that at least two threads can be heated, in particular at a different temperature. The at least two threads are separated from one another with the aid of the at least one twist-stop element or brought together along the conveying direction adjacent to the twist-stop element. Within the heating device, in particular at least up to the twist-stop element arranged within and / or on the heating device, the two threads move along the conveying direction in an untwisted or untwisted or smooth state. In this way, the two threads can be heated stably, quickly and effectively by means of the heating device.Additionally or alternatively, this can result in a reduction in energy consumption. Following the at least one twist-stop element along the conveying direction, the two threads are twisted or intertwined, thereby crimping them together. Different temperatures can be achieved for the two threads using at least two of the heating elements and / or heated godets.
[0024] It is also advantageous if the at least two grooves are separated from one another by the at least one swirl-stop element. Preferably, the at least two grooves are separated from one another by at least two of the swirl-stop elements designed as pins and / or the at least one swirl-stop element designed as a partition. In this way, a uniform separation of the two threads within the at least one heating element can be achieved. Furthermore, it is advantageous if the at least two threads form a connection point which follows the at least one swirl-stop element along the conveying direction, wherein the connection point is preferably arranged in the region of the high-temperature section, downstream of the high-temperature section along the conveying direction and / or between the heating device and a cooling device, in particular closer to the heating device.The connection point is the point where the at least two threads meet after heating or after the high-temperature section. Following the connection point, the at least two threads are twisted together. This allows the at least two threads to be crimped together. The shorter distance between the heating device and the connection point compared to a connection point with a cooling device, or the fact that the connection point is located within the heating device, ensures the highest possible crimp, since the threads at the connection point have a very high temperature.
[0025] Furthermore, it is advantageous if the texturing unit has an input feed unit and / or an output feed unit. The at least one thread is drawn between the input feed unit and the output feed unit. Furthermore, the at least one thread can be conveyed along the conveying direction.
[0026] It is also advantageous if the input feed mechanism is located upstream of the heating device along the conveying direction and / or if the at least one heated godet at least partially forms the input feed mechanism. This leads to a more compact design of the texturing unit.
[0027] Furthermore, a textile machine, in particular a texturing machine and / or spinning machine, with at least one texturing unit is proposed. According to the invention, the texturing unit is designed according to the preceding description, wherein the aforementioned features can be present individually or in any combination.
[0028] Furthermore, a method for texturing at least one thermoplastic thread using at least one texturing unit is proposed, in which the at least one thread is heated using a heating device. Furthermore, a twist is introduced into the at least one thread.
[0029] In the method according to the invention, the twist is stopped within and / or on the heating device, in particular with the aid of a twist stop element. This allows the texturing zone to be kept as small as possible. In addition, the conveying speed of the at least one thread can be increased. The texturing unit is preferably designed according to the preceding description, whereby the aforementioned features can be present individually or in any combination.
[0030] Further advantages of the invention are described in the following exemplary embodiments. It shows:

[0035] Figure 6 is a schematic representation of a texturing unit according to a sixth embodiment.
[0036] In the following description of the figures, the same reference numerals are used for identical and / or at least comparable features in the various figures. The individual features, their design, and / or mode of operation are usually only explained in detail when first mentioned. If individual features are not explained in detail again, their design and / or mode of operation correspond to the design and mode of operation of the features with the same or identical functions already described.
[0037] Figure 1 shows a schematic representation of a texturing unit 1 of a textile machine according to one exemplary embodiment. The illustrated exemplary embodiment shows a greatly simplified design of the texturing unit 1. For example, as is known in the prior art, at least one thread 3 to be textured with the aid of the texturing unit 1 can be deflected once or multiple times. Furthermore, the illustrated exemplary embodiment shows that at least two threads 3a, 3b are textured or twisted together simultaneously or together. It is also conceivable that only one of the threads 3a, 3b or more than two threads 3a, 3b are textured.
[0038] The at least one thread 3 is moved along a conveying direction 6 within the texturing unit 1 and is thereby stretched and / or textured. For this purpose, the texturing unit 1 has at least one input feed mechanism 16 and at least one output feed mechanism 17. In the illustrated embodiment, a first thread 3a is twisted with a second thread 3b, forming a third thread 3c. The third thread 3c thus comprises the first thread 3a and the second thread 3b, which are twisted together. The third thread 3c can also be called a textured thread, yarn, or textured yarn. For guiding the at least one thread 3, in particular the first thread 3a and the second thread 3b, the texturing unit 1 comprises at least one thread guide 13.
[0039] The texturing unit 1 comprises a heating device 2 for heating the at least one thermoplastic thread 3. In the illustrated embodiment, the first thread 3a and the second thread 3b are heated, in particular independently of one another. Adjacent to the heating device 2 along the conveying direction 6, the texturing unit 1 in the illustrated embodiment has a cooling device 15 that cools the at least one thread 3, here the third thread 3c. Alternatively, it is also conceivable for the at least one thread 3 to be cooled by the ambient air instead of by the optional cooling device 15.
[0040] Furthermore, the texturing unit 1 comprises a twist unit 4 for introducing a twist into the at least one thread 3. In the exemplary embodiment shown, the twist acts on the third thread 3c via the twist unit 4. To stop or reduce the twist, the texturing unit 1 comprises at least one twist stop element 5. The at least one twist stop element 5 is arranged on and / or within the heating device 2. Thus, the twist introduced into the at least one thread 3, in particular onto the third thread 3c, by the twist unit 4 can be stopped and / or reduced at the twist stop element 5. The twist acting counter to the conveying direction 6, emanating from the twist unit 4, into the at least one thread 3, in particular onto the third thread 3c, can thus be stopped upstream of and / or within the heating device 2. A connection point 14 is formed along the conveying direction 6, following and / or adjacent to the twist stop element 5.From this connection point 14, the first thread 3a is connected or twisted with the second thread 3b to form the third thread 3c. In the illustrated embodiment, the connection point 14 between the heating device 2 and the cooling device 15 is arranged closer to the heating device 2.
[0041] In the exemplary embodiment shown, the heating device 2 comprises at least one heating element 7 and at least one heated godet roll 12a, 12b. Additionally or alternatively, the at least one heated godet roll 12a, 12b has at least one traversing roller 19 and / or the at least one traversing roller 19 is assigned to the at least one heated godet roll 12a, 12b. It is also conceivable for the heating device 2 to comprise only the at least one heating element 7 or the at least one heated godet roll 12a, 12b. In the exemplary embodiment shown, the input feed mechanism 16 is designed as at least one heated godet roll 12a, 12b. Thus, the at least one thread 3, in particular the first thread 3a and / or the second thread 3b, can be conveyed along the conveying direction 6 and also heated with the aid of the heated godet roll 12a, 12b.In the embodiment shown, the heating device 2 has two heated godets 12a, 12b, so that the first thread 3a and the second thread 3b can be heated or heated independently of one another and / or to different temperatures.
[0042] Additionally or alternatively, the at least one input feed mechanism 16 can be configured similarly to the output feed mechanism 17. Thus, the input feed mechanism 16, without the at least one heated godet roll 12a, 12b, can only ensure the transport of the at least one thread 3, in particular the first thread 3a and / or the second thread 3b. Additionally or alternatively, the texturing unit 1 can have at least one of the heated godets 12a, 12b for one of the at least two threads 3a, 3b and at least one of the unheated input feed mechanisms 16 for the other of the at least two threads 3a, 3b.
[0043] In the exemplary embodiment shown, the heating element 7 extends at least partially along the conveying direction 6. The heating element 7 comprises at least one groove 10 through which the at least one thread 3, in particular the first thread 3a and / or the second thread 3b, can be transported along the conveying direction 6. In addition, the heating element 7 comprises a thread inlet 9 and a thread outlet 8 through which the at least one thread 3 can enter or exit. Thus, the at least one thread 3 is continuously heated along the conveying direction 6. In the region of the thread outlet 8, the at least one thread 3 thus reaches its maximum temperature. In the region of a last third of the heating device 2 and / or the groove 10, which is measured from the thread outlet 8 against the conveying direction 6, a high-temperature section 11 is arranged in the exemplary embodiment shown.The high-temperature section 11 can be regarded as the area and / or point within the heating device 2 where the maximum temperature prevails. Preferably, the at least one swirl-stop element 5 is arranged within the heating element 7 and / or within the groove 10, in particular in the area of the high-temperature section 11 and / or in the area of the thread outlet 8. The high-temperature section 11 is spaced from the thread outlet 8, as shown in the present embodiment of Figure 1. The temperature at the thread outlet 8 is usually already slightly reduced, in particular due to the interaction with the environment and / or the cooling device 15.
[0044] In the illustrated embodiment, the swirl-stopping element 5 is designed as a pin. Furthermore, the swirl-stopping element 5 has a circular or round cross-section. The swirl-stopping element 5 is arranged within the groove 10 of the heating element 7 and separates the first thread 3a from the second thread 3b. Due to the round cross-section, the swirl can be stopped as gently as possible. The connection point 14 can, as shown, be spaced apart from the swirl-stopping element 5 along the conveying direction 6 or, in particular due to the round cross-section, can rest against the swirl-stopping element 5. Alternatively, the at least one swirl-stopping element 5 can have a semicircular, elliptical, or angular cross-section.
[0045] Figure 2 shows a schematic section of a texturing unit 1 according to a second exemplary embodiment. In contrast to the exemplary embodiment in Figure 1, the section of the texturing unit 1 in the exemplary embodiment in Figure 2 shows only the heating device 2, in particular the heating element 7, the twist stop element 5 and the first thread 3a, the second thread 3b and the third thread 3c. The texturing units 1 shown here and in Figures 3 and 4 can have the components additionally shown in Figure 1, in particular the twist unit 4, the at least one heated godet roll 12a, 12b, the at least one thread guide 13, the cooling device 15, the input feed mechanism 16 and / or the output feed mechanism 17. It is also conceivable that the texturing units 1 of the exemplary embodiments in Figures 2 to 4 are designed to texture only one or more than two threads 3a, 3b.
[0046] Additionally or alternatively, the texturing units 1 can be designed without the heated godet 12a, 12b and / or the cooling device 15.
[0047] Additionally or alternatively, the texturing unit 1 can comprise only one of the two heated godets 12a, 12b and / or two heated godets 12a, 12b. It is also conceivable for the texturing unit 1 not to include a heating element 7. Reference is made to Figures 4 and 5.
[0048] In contrast to the embodiment of Figure 1, the embodiment of Figure 2 has a first twist-stop element 5a and a second twist-stop element 5b. The second twist-stop element 5b has essentially the same effect as the twist-stop element 5 of the embodiment of Figure 1. The first twist-stop element 5a, which can also be designed as a pin, is spaced from the second twist-stop element 5b along the conveying direction 6. This allows the first thread 3a and the second thread 3b to be separated from one another within the heating element 7. Contact between the first thread 3a and the second thread 3b can thus be prevented between the two twist-stop elements 5a, 5b.
[0049] In addition, the second twist-stop element 5b and the connection point 14 are arranged within the heating element 7 and within the groove 10, respectively. Thus, the twist of the at least one thread 3 can be stopped after reaching the highest possible or maximum temperature. A similar arrangement of the twist-stop element is also possible in the embodiment shown in Figure 1.
[0050] Figure 3 shows a schematic section of a texturing unit 1 according to a third embodiment. Similar to the embodiment of Figure 2, only the heating device 2, in particular the heating element 7, the twist-stopping element 5, and the first thread 3a, the second thread 3b, and the third thread 3c are shown here.
[0051] In contrast to the exemplary embodiments of Figures 1 and 2, the exemplary embodiment of Figure 3 has a swirl-stopping element 5 designed as a partition. The swirl-stopping element 5 designed as a partition extends along the conveying direction 6. In the exemplary embodiment shown, the heating element 7 comprises two grooves 10a, 10b that are separated from one another by the partition. The partition extends from the thread inlet 9 to the high-temperature section 11 and / or ends along the conveying direction 6 before the high-temperature section 11. In the exemplary embodiment shown, the partition ends within the heating element 7. As a result, one end 18 of the swirl-stopping element 5 designed as a partition is arranged within the heating element 7. The end 18 of the swirl-stopping element 5 designed as a partition can be circular, as shown in the exemplary embodiment. Alternatively, the end 18 can be elliptical and / or angular.Additionally or alternatively, the dividing wall can extend to the thread outlet 8. Additionally or alternatively, the twist-stop element 5 designed as a dividing wall can have a circular, semicircular, or elliptical cross-section. The cross-section is understood to be the cross-section normal to the conveying direction 6. This circular, semicircular, or elliptical cross-section of the twist-stop element 5 designed as a dividing wall can alter the course of the at least one thread 3 within the at least one groove 10a, 10b and / or guide the at least one thread 3 within the at least one groove 10a, 10b.
[0052] Figure 4 shows a schematic section of a texturing unit 1 according to a fourth embodiment. Similar to the embodiments of Figures 2 and 3, only the heating device 2, in particular the heating element 7, the at least one twist-stopping element 5, and the first thread 3a, the second thread 3b, and the third thread 3c are shown here.
[0053] Similar to the exemplary embodiment in Figure 3, the texturing unit 1 of the exemplary embodiment in Figure 4 also has the first twist-stop element 5a designed as a dividing wall. However, here the dividing wall extends along the conveying direction 6 from the thread inlet 9 to the thread outlet 8. In addition, the texturing unit 1 in the exemplary embodiment shown has the second twist-stop element 5b, which is designed as a pin. The pin is arranged or fastened to the heating element 7. For example, the second twist-stop element 5b designed as a pin is arranged and / or fastened to the first twist-stop element 5a designed as a dividing wall. Thus, the second twist-stop element 5b primarily has a twist-stopping effect on the at least one thread 3. The first twist-stop element 5a designed as a dividing wall ensures that the first thread 3a and the second thread 3b are separated from one another or run apart from one another within the heating element 7.The first swirl stop element 5a, designed as a partition wall, also separates the two grooves 10a, 10b of the heating element 7 from each other.
[0054] Since the second twist-stop element 5b, designed as a pin, is located or arranged at the end 18 of the first twist-stop element 5a, designed as a partition, this can, for example, be designed to be angular. The design of the end 18 of the first twist-stop element 5a, designed as a partition, is less relevant for the twist-stopping effect and / or the gentle deflection. For the gentle deflection of the at least one thread 3, the second twist-stop element 5b preferably has a circular, semicircular, or elliptical cross-section. As an alternative to the exemplary embodiment shown, it is also conceivable, among other things, for the second twist-stop element 5b, designed as a pin, to be semicircular, so that connection and / or fastening to the heating element 7, in particular to the second twist-stop element 5b, designed as a partition, is simplified.
[0055] Figure 5 shows a schematic representation of a texturing unit 1 of a textile machine according to a fifth exemplary embodiment. In contrast to the exemplary embodiments described above, the heating device 2 does not have a heating element 7 but rather at least two of the heated godets 12a, 12b. Furthermore, in contrast to the exemplary embodiment of Figure 1, the at least two heated godets 12a, 12b are arranged in a row along the conveying direction 6. The cooling device 15, the twisting unit 4, and / or the output delivery mechanism 17, however, are designed similarly to the exemplary embodiment of Figure 1 and will therefore not be described again.
[0056] In the illustrated embodiment, the at least two threads 3a, 3b are first looped around a first heated godet 12a. The at least two threads 3a, 3b are heated and transported along the conveying direction 6. Subsequently, the at least two threads 3a, 3b loop around a second heated godet 12b. It is conceivable that the at least two threads 3a, 3b loop around the at least two heated godets 12a, 12b several times, so that the heat input can be increased. Preferably, the at least two heated godets 12a, 12b are rotated and / or operated at different speeds, so that the at least two threads 3a, 3b are drawn.
[0057] Furthermore, in the illustrated embodiment, each of the heated godets 12a, 12b is assigned at least one of the laying rollers 19. With the aid of the at least one laying roller 19, the at least two threads 3a, 3b can be guided and / or laid parallel to one another on the at least one heated godet 12a, 12b and / or on the surface of the at least one heated godet 12a, 12b.
[0058] As already described above, the at least two threads 3a, 3b wrap around the at least one heated godet 12a, 12b. Due to the constant heat input to the at least two threads 3a, 3b, the high-temperature section 11 in the illustrated embodiment is arranged on the surface of the second heated godet 12b, in particular shortly before the at least two threads 3a, 3b reach the thread outlet 8 and / or detach from the surface of the second heated godet 12b.
[0059] In the illustrated embodiment, the twist stop element 5 is arranged in the region of the second heated godet roll 12b or between the thread inlet 9 and the thread outlet 8 of the heating device 2. The twist stop element 5 preferably acts on the at least two threads 3a, 3b at the last and / or penultimate wrap between the traversing roller 19 and the second heated godet roll 12b. As a result, the twist of the twist unit 4 acts on the at least two threads 3a, 3b or on the third thread 3c in the region of the high-temperature section 11. Here, too, the twist stop element 5 is preferably designed as a pin.
[0060] Figure 6 shows a schematic representation of a texturing unit 1 of a textile machine according to a sixth exemplary embodiment. Similar to the exemplary embodiment in Figure 5, the heating device 2 here also does not have a heating element 7 but at least two of the heated godets 12a, 12b, 12c. In contrast to the exemplary embodiment in Figure 5, three heated godets 12a, 12b, 12c are shown here by way of example. The first heated godet 12a and a third heated godet 12c of the exemplary embodiment in Figure 6 can, similar to the exemplary embodiment in Figure 5, also be designed as the common first heated godet 12a. Accordingly, in the exemplary embodiment in Figure 5, it is also conceivable for the first heated godet 12a to be divided into two heated godets 12a, 12c in accordance with the exemplary embodiment in Figure 6.The cooling device 15, the swirl unit 4 and / or the output delivery mechanism 17 are also designed similarly to the embodiment of Figure 1 and are therefore not described again.
[0061] In the embodiment of Figure 6, the at least two threads 3a, 3b enter the heating device 2 via the thread inlet 9. The first thread 3a wraps around the first heated godet 12a, and the second thread 3b wraps around the third heated godet 12c. To guide the at least two threads 3a, 3b on the first heated godet 12a and / or the third heated godet 12c, a respective traversing roller 19 is assigned to each of them. Heat transfer occurs along the plurality of wraps of the at least two threads 3a, 3b on the at least one heated godet 12a, 12b, 12c.
[0062] In the embodiment shown in Figure 6, the twist-stop element 5 is designed as a partition wall. The partition wall is preferably arranged and / or attached to one of the heated godets 12a, 12b, 12c. For example, the twist-stop element 5 can be designed as a twist-stop element that rotates with the at least one godet 12a, 12b, 12c. This also ensures that the twist acts on the at least one thread 3a, 3b in the area of the high-temperature section 11.
[0063] Additionally or alternatively, it is conceivable that the at least one groove 10 of the at least one heating element 7 according to the embodiments of Figures 1 to 4 is arranged on the surface of at least one of the heated godets 12a, 12b, 12c. Thus, the guidance of the at least one thread 3a, 3b can be assumed with the aid of the at least one groove 10 and / or the at least one groove 10 can have the at least one twist-stop element 5.
