Description

Technical Field

[0001] The present invention relates to a spinning cone according to claim 1. The present invention relates to a fiber machine according to claim 11, particularly an air jet spinning machine. The present invention relates to a method for cleaning a spinning cone according to claim 12.

[0002] The spinning cone(s) of an air jet spinning nozzle are generally known in the prior art. They are used in fiber machines, particularly air jet spinning machines, especially for spinning the incoming fibers into yarns or threads. A single spinning cone particularly performs the function of yarn formation. At the tip of the spinning cone, the winding fibers of the fibers supplied from the supplied fiber composite rotate particularly in an air stream and are formed into yarns. Known spinning cones are prone to dirt, which can lead to deposits, so cleaning is necessary. This can cause downtime of the fiber machine, which restricts resources and causes costs.

[0003] Therefore, the object of the present invention is to reduce the cleaning effort, thereby particularly reducing resource consumption and associated costs. Furthermore, the object of the present invention is to improve the spinning quality, particularly. Furthermore, the object of the present invention is to improve the spinning stability, more preferably to affect the yarn characteristics.

[0004] The above object is particularly solved by a spinning cone having the features according to claim 1. More particularly, the above object is solved by a fiber machine having the features according to claim 11, particularly an air jet spinning machine. More particularly, the above object is solved by a method for cleaning a spinning cone having the features according to claim 12.

[0005] Preferred embodiments of the present invention are the subject matter of the dependent claims.

[0006] According to one aspect, the above object is solved by a spinning cone having the features of claim 1.

[0007] The spinning cone comprises an outer surface and a spinning cone cavity. The spinning cone cavity is designed and positioned to accommodate the supplied fibers for spinning yarn and to feed them into a yarn outlet channel adjacent to the spinning cone cavity. In other words, the spinning cone has an opening formed at the tip of the spinning cone, which transitions into at least one component of the so-called yarn outlet channel of the air-jet spinning nozzle, or into a yarn passage that completely forms the yarn outlet channel. In this case, the spinning cone is designed and positioned to perform a rotational cycle (rotationsumlauf) of the wound fibers of the supplied fibers with respect to the axis of symmetry of the spinning cone for spinning yarn. The spinning cone comprises at least one obstruction device, which is designed and positioned to impart motion, in particular vibration, to the rotational cycle of the wound fibers in contact with the obstruction device. In other words, the imparted motion is caused by the obstruction device and is different from the pure cyclic motion (umlaufbewegung) of the wound fibers around the spinning cone, which is normally generated by the vortex of air in the air-jet spinning nozzle. In that case, cleaning can be improved by imparting motion to the wrapped fibers, particularly by adding vibration to rotational cyclic motion.

[0008] Generally, fiber composites, also called fiber strands, are fed into a spinning cone for spinning yarn, and within an air-jet spinning nozzle, compressed spinning air is supplied as specified to generate an air vortex, separating them into core fibers and wound fibers, also called peripheral fibers, that are connected to the core fibers. The core fibers are drawn into the spinning cone cavity during the spinning process and guided along the adjacent yarn exit channel. In this case, the rotating wound fibers, which circulate around the spinning cone in the rotational direction, are carried into the spinning cone cavity by the core fibers and, as they are carried, rotate and wrap around the core fibers to form yarn, also called spun yarn.

[0009] Normally, during the spinning process, entangled fibers rotating around the spinning cone can contaminate its surface. These contaminants can include spinning agents, fiber components, or deposits on the outside of the nozzle protrusions due to dust. These contaminants can affect spinning behavior (yarn breakage) and yarn quality. Spinning cones with smooth, unstructured inlet and tip designs are particularly susceptible to contamination by fiber materials such as fiber residue and debris, which can accumulate on the cone's surface. In such cases, imparting motion, especially vibration, to the entangled fibers allows for interaction between the fibers and any deposits and / or contaminants that may accumulate on the cone's surface. This allows the contaminants and fouling to be detached from the cone's surface and expelled by air vortices. This, in particular, can prevent the accumulation of contaminants. Therefore, a spinning cone can function as a self-cleaning cone. As a result, contaminants are discharged, in particular, from textile machines equipped with air-jet spinning nozzles having spinning cones and from their air-jet spinning units.

[0010] The spinning cone may have a smooth, unstructured design at the entrance (also called the spinning cone cavity and / or tip with sides). The wound fiber slides particularly along the entrance slope of the spinning cone and, particularly here, in direct contact with the surface of the cone, especially in the region of the sides and / or the region of the spinning cone cavity. In this case, the spinning cone cavity is designed to accommodate the wound fiber and feed it into the yarn exit channel. This makes it possible to spin yarn. The smooth, unstructured tip does not generate vibration transmission of the fiber or yarn (imparting vibration to the rotational cycle motion).

[0011] The spinning cone allows the individual wound fibers of the supplied fiber to spin yarn by performing relative motion on the sides and / or surfaces of the spinning cone cavity through a rotational cycle about the central axis of symmetry of the spinning cone.

[0012] By providing the interference device according to the present invention, the wound fibers can vibrate and come into contact with the outer region (side) of the spinning cone. Alternatively or additionally, they can come into contact with the surface surrounding the spinning cone cavity. The transition from the spinning cone cavity located inside the spinning cone to the outer side is formed by an inlet slope. In this case, the contact of the wound fibers with the outer region improves the cleaning of the spinning cone in particular. This is especially true when using spinning cones in textile machinery for producing yarn or thread. In this case, the type of spinning cone described herein may also be called a self-cleaning spinning cone.

[0013] In one embodiment, contact between individual wound fibers and the outer surface of the spinning cone can also be achieved by forming a web.

[0014] In particular, a structure can be provided in the region of the inlet slope at the tip of the spinning cone in the fiber contact area (the transition area from the side to the spinning cone cavity). This can be described as an obstruction device. In embodiments, this can be formed with a gear-like design having lowered teeth and / or raised teeth.

[0015] By providing a structured inlet slope along the inlet radius or across the entire tip region of the spinning cone, the sliding wound fibers can be vibrated and excited, allowing them to directly contact the outer region of the spinning cone through vibration. This helps to keep this region virtually free of deposits.

[0016] The structure of the spinning cone, particularly the inner region surrounding the spinning cone cavity, can influence yarn quality and spinning stability by controlling the movement of wound fibers in the binding zone. In this case, the region where individual wound fibers are spun into yarn is specifically called the binding zone.

[0017] Rings or spiral webs can be formed on the outer surface of the spinning cone, particularly in the lateral regions, which, in their characteristic form, allow the wrapped fibers to come into direct contact with these regions of the spinning cone, and direct the airflow (air cushion) into so-called channels. In this case, the depressions in the structure are specifically called channels. This deflects the airflow into the channels, thereby achieving controlled contact of the wrapped fibers with specific regions of the spinning cone.

[0018] In another embodiment, the motion may include vibrations with respect to at least one surface. In this case, the surface can be selected from either the outer surface or one of the surfaces surrounding the spinning cone cavity. The surface may have an inner surface in particular. This inner surface may be structured, i.e., it is not smooth but has various features such as ridges and / or depressions. The motion may have a radial motion component with respect to the axis of symmetry. This may be designed to lift, at least temporarily, some of the entangled fibers interacting with the fringe device off the surface. In this case, in particular, by temporarily lifting the entangled fibers off the surface, a striking motion of the entangled fibers can be produced when the entangled fibers reappear on the surface. This can improve cleaning and, by extension, improve spinning quality.

[0019] Here and elsewhere, the receiving region can be called the spinning cone cavity, where the aforementioned wound fibers are combined with the core fibers of the supplied fibers, particularly under rotational cycle motion, to form a yarn, which can then be guided through a yarn exit channel (also called a yarn guide) adjacent to the spinning cone cavity. The surface that forms the surface surrounding the spinning cone cavity, which can be located within a diameter about the axis of symmetry, can be called the spinning cone cavity surface.

[0020] In that case, the expression that it can have a radial component of motion with respect to the axis of symmetry can be understood in particular as meaning that at least one of the vectors can form a motion vector system having a radial component of motion. In other words, at least one region of the wrapped fiber can be moved radially outward after interaction with the interfering device. Alternatively or additionally, a region of the wrapped fiber can also be moved radially inward, which may be a radial backward motion or a radially reverse motion. This can form the impact described here and elsewhere. This impact can prevent (or make it less likely for) fouling material to remain attached to the spinning cone and the aforementioned surface. This, in particular, increases the time until cleaning of the spinning cone is required, which reduces cleaning resources and, consequently, costs. Furthermore, this can also improve the quality of the spinning process. This may be particularly due to the slow increase of fouling material. Since large amounts of fouling material are not mixed into the spun yarn, the quality of the resulting yarn is improved.

[0021] In that case, the phrase "at least temporarily" refers specifically to a situation where such a backward movement can be used during the strike to return the wrapped fibers to one of the aforementioned surfaces. This makes it possible to perform a strike with the advantages described elsewhere.

[0022] In another embodiment, the motion may have vibrations including a motion component in a plane parallel to at least one surface. The surface can be selected from the outer surface and / or the spinning cone cavity surface. The spinning cone cavity surface may be the inner surface in particular. In this case, the motion component may be designed to change the velocity of at least some of the wrapped fibers that interact with the interfering device during the rotational cycle, at least temporarily. The velocity change may be acceleration and / or braking in particular. This allows a cleaning motion to be performed. Furthermore, by accelerating and / or braking at least some of the wrapped fibers, they can be guided particularly over a structured surface. This is applied to a number of wrapped fibers, relatively continuously.

[0023] The motion of the wrapped fibers described here and elsewhere applies particularly to at least one wrapped fiber, but especially to multiple wrapped fibers, though not necessarily to all wrapped fibers. In other words, this means that some wrapped fibers may not interact with the obstruction point during the rotational cycle, for example, due to interactions with other wrapped fibers. However, these may be lifted off the surface by other wrapped fibers.

[0024] A plane parallel to one of the described surfaces is, in particular, a plane that may have a tangent plane to a point and / or line segment of one of the surfaces. More specifically, a corresponding change in velocity can also be made directly on one of the aforementioned surfaces.

[0025] In another embodiment, the interfering device may have at least one embodiment that includes, namely, at least one notch, at least one tooth, and / or at least one surface structuring. This allows the interfering device to be formed by a geometric shape that is physically and structurally easy to realize in order to achieve the technical advantages and / or effects described elsewhere.

[0026] In that case, the notch can be, in particular, a material recess designed and arranged to expand the surface. In that case, the notch can be arranged in the region of the inlet slope. In that case, the wound fiber can be introduced into the notch, particularly in the rotation cycle, whereby on the one hand, a radial inward impact movement can be performed within the rotation cycle, but when going out, particularly when accelerating out of the notch, an outward movement can also be performed, so that an impact movement can be performed when the wound fiber lands again.

[0027] According to one aspect, at least one notch can be designed symmetrically. Alternatively, the notch can also be designed asymmetrically. In that case, the asymmetry makes it possible, in particular, to control the speed of the rotation cycle movement when entering the notch with respect to the movement of the wound fiber out of the notch. Thereby, the introduction of vibration can be improved.

[0028] The tooth can be an upper structure in which the inlet slope of the tip of the spinning cone extends in at least one direction parallel to the axis of symmetry. Thereby, the introduction of vibration with respect to the notch during the rotation cycle can be reversed. This may be advantageous depending on the structure of the base fiber and / or the wound fiber. In the above-described embodiment, the impact can bring about an improvement in cleaning.

[0029] According to one aspect, at least one tooth can be designed symmetrically or asymmetrically. In that case, the corresponding advantages and technical effects apply as described for the asymmetric notch.

[0030] According to one aspect, a surface structuring can be provided that extends, in particular, at least partially in a spiral shape. In that case, in particular, the surface structuring can be intended to structure the inside of the surface of the spinning cone cavity. Thereby, a region can be defined that makes it possible to guide the wound fiber into the spinning cone cavity. Thereby, the spinning quality can be improved.

[0031] According to another aspect, it is possible to assign an inner surface, particularly to the tip of a spinning cone having a surface structure, in which case the inner surface is formed in a concave shape. Thereby, a region can be defined that enables guiding the wound fibers into the spinning cone cavity. Thereby, the spinning quality can be improved.

[0032] As described elsewhere, in order to perform impacts and, as described elsewhere, to perform a translational movement relative to one of the surfaces, a hybrid form can be contemplated in which at least one tooth, at least one notch, and / or at least one region having a surface structure are provided. Thereby, the spinning quality can be improved. Thereby, the cleanliness of the spinning cone can be further improved.

[0033] According to another aspect, it can be contemplated that at least one notch transitions into at least one tooth. Thereby, the impact movement can be strengthened, whereby the cleaning can be further improved, and thereby it may be possible to further save resources. In that case, it can also be contemplated that the notch and / or the tooth are formed symmetrically and / or asymmetrically. In that case, this combination can be designed such that the effects of cleaning and movement control are particularly effective for the application. This may depend, for example, on the selected type of yarn or thread to be spun.

[0034] In another embodiment, at least one notch can be formed asymmetrically. In this case, the notch may have a long side (so-called long side) and a short side (so-called short side). These are arranged in particular at two notch angles. In this case, a steeper notch angle is arranged in particular in the direction of the rotational cycle. This allows for a quicker avoidance movement from the notch, thereby enhancing the striking motion. On the gently descending long side, the notch descends too quickly at this point, preventing the wrapped fibers from being lifted from one of the surfaces, so the wrapped fibers can "start moving" and, in this case, be guided. This improves the control of movement and thus improves cleaning. This can also improve spinning quality.

[0035] In another embodiment, the tip of the spinning cone may have an outer diameter. This is particularly designed symmetrically with respect to the axis of symmetry of the spinning cone. In this case, the interfering structure can be designed and positioned so that it protrudes beyond the outer diameter. This can amplify the vibration of the fibers. In this case, in particular, the wound fibers can be moved away from the sides by the protruding interfering device in a controlled motion, and then intended to strike the spinning cone again in a striking motion.

[0036] In another embodiment, the interfering device can be formed as a notch on the inner surface. In this case, the notch is designed such that the recess forming the notch does not penetrate the side surface. This allows the aforementioned principle to be applied to the inner surface, particularly the spinning cone cavity surface.

[0037] In an independent embodiment, the above problems can be solved in particular by a textile machine, in particular an air-jet spinning machine. The textile machine may be equipped with at least one air-jet spinning nozzle having a spinning cone, as described above. This makes it possible to reduce cleaning effort, and thereby reduce resource consumption and the associated costs. Furthermore, it is possible to improve spinning quality.

[0038] In that case, textile machinery can be described by its methods, and especially by its characteristics, effects, and advantages, as a system. Furthermore, textile machinery can be described by the characteristics of the spinning cone apparatus. In particular, characteristics across various categories are suitable for describing different categories.

[0039] In another independent embodiment, the above problem is solved by an air-jet spinning nozzle. The structure of an air-jet spinning nozzle is well known by the prior art. According to one preferred embodiment, the air-jet spinning nozzle may comprise a two-part housing, and the first and second housing portions may be designed to be movable relative to each other in order to allow the air-jet spinning nozzle to be opened and closed. The first housing member supports a fiber introduction element for supplying a fiber composite or fiber strand to be fed into the air-jet spinning nozzle into the internal space of the air-jet spinning nozzle. The second housing member is preferably located opposite the fiber introduction element in the closed state of the air-jet spinning nozzle and supports a yarn-forming element including a spinning cone according to one of the embodiments described above. A yarn exit channel may be formed by the spinning cone and preferably additionally by the remaining area of ​​the yarn-forming element. The yarn produced by the air-jet spinning nozzle is drawn out of the air-jet spinning nozzle through the yarn exit channel until it is led out therefrom. In the closed state of the air-jet spinning nozzle, the first and second housing portions define a vortex chamber surrounding at least the spinning cone, through which the nozzle opening is connected, and the nozzle opening, together with the first and / or second housing portions, may be designed to supply so-called spinning compressed air to the vortex chamber so that a vortex of air is generated in the vortex chamber. The vortex of air results in the rotational motion of the wrapped fiber described.

[0040] In another independent embodiment, the above problem is solved by a method for cleaning spinning cones, particularly the aforementioned spinning cones. The method may include the step of performing a rotational cycle of the wound fibers around the axis of symmetry of the spinning cone. The method may include the step of causing the wound fibers to interact with at least one interfering device during a complete rotational cycle. In this case, the interaction may be designed to produce the imparting of motion of the wound fibers interacting with the interfering device. The motion may be vibration in particular. This makes it possible to reduce cleaning effort, and thereby reduce resource consumption and consequently costs. Furthermore, it is possible to improve spinning quality.

[0041] In that case, the method can be described in particular by the features, effects, and advantages of the apparatus and / or system. Features across various categories are particularly suitable for describing different categories.

[0042] In summary, and in other words, this means that two or more notches can be formed at the tip of the cone with asymmetrical or symmetrical notch angles. In this case, the asymmetrical notches can be designed so that the steeper notch angle is oriented in the direction of fiber rotation. This results in vibration transmission of the wrapped fibers. In this case, the notches at the tip of the cone can extend the selected contour beyond the outer surface of the cone, thereby amplifying the vibration of the wrapped fibers sliding along the outer contour. Wrapped fibers vibrated through the notches result in a particularly clean effect and better spinning stability.

[0043] The operating principle is based on the "impact" of the yarn-forming element with particularly vibrated wrapped fibers on the surface of the spinning cone. The vibration of the wrapped fibers is generated particularly through the corresponding contour of the tip of the spinning cone. The impact of the wrapped fibers on the surface of the spinning cone can cause the removal of dirt or deposits attached thereto, thereby automatically cleaning the surface of the spinning cone without the addition of any additives. Optionally, with respect to the apparatus and method, additives may be added to enhance and / or improve the cleaning effect.

[0044] Alternatively or additionally, the structure of the spinning cone, particularly in the region inside the spinning cone cavity, can be controlled to influence the movement of the wrapped fibers in the binding zone, thereby affecting yarn quality and spinning stability. In this case, the structure can be formed as a hindering device that imparts fiber movement in accordance with its structural characteristics.

[0045] A ring or spiral web can be formed on the outside of the spinning cone, which, in its characteristic form, allows the fibers to come into direct contact with these areas of the spinning cone and direct airflow (air cushion) into channels. In this case, the channels are particularly embossed structures or cavities and / or depressions between provided structures. This allows the airflow to be deflected into the channels, thereby achieving controlled contact of the wound fibers with specific areas of the spinning cone.

[0046] Alternatively or additionally, fouling of the outer region (or sides thereof) of the spinning cone can be reduced or completely avoided by increasing the smoothness of the spinning cone material (e.g., by a polishing process) or by providing a fouling-resistant layer (such as Teflon). [Brief explanation of the drawing]

[0047] The following describes exemplary embodiments of the present invention in detail with reference to the drawings. In this description, the following will be shown in general terms and exemplary. [Figure 1A]This figure shows one embodiment of a spinning cone tip having an asymmetrical recess. [Figure 1B] This figure shows one embodiment of a spinning cone tip having a symmetrical recess. [Figure 2] This is a diagram of one embodiment of an air jet spinning nozzle. [Figure 3A] This is a schematic side view of one embodiment of a spinning cone equipped with a spinning cone tip having a symmetrical recess. [Figure 3B] This is a schematic side view of one embodiment of the tip of a spinning cone having an asymmetrical recess. [Figure 3C] This is a schematic diagram of angles. [Figure 4A] This is a schematic cross-sectional view of one embodiment of the tip of a spinning cone. [Figure 4B] This is a cross-sectional view of one embodiment of an insert having a structured surface. [Figure 5] This is a schematic diagram of the method.

[0048] The same reference numeral is used for components or structures with the same function and / or similar type.

[0049] Figure 1A shows one embodiment of a spinning cone tip 110 having an asymmetric recess 10. In this case, the spinning cone tip 110 is located particularly on a spinning cone 100, as illustrated in Figure 3A. In this case, the spinning cone tip 110 has, in particular, an outer surface 20 and a spinning cone cavity 18. In this case, as shown in Figure 2, the spinning cone cavity 18 is designed and located particularly to accommodate the wound fibers 26a of the supplied fiber. In this case, the wound fibers 26a located in the spinning cone cavity 18 can be supplied to the yarn outlet channel 42 for spinning yarn 26b. This is done particularly by the spinning cone 100, which is designed and located to perform a rotational cycle 50 of the wound fibers 26a in the rotational direction U with respect to the axis of symmetry 34 of the spinning cone 100.

[0050] In the illustrated embodiment, the spinning cone 100 has two obstructing devices located on opposite sides of each other, which are exemplary asymmetric recesses 10. These may also be called notches. In this case, they are designed and positioned to contact the wound fiber 26a during its rotational cycle 50. In this case, as shown in Figure 2, the wound fiber 26a moves from the outer surface 20 in which they contact, over the spinning cone edge 16, into the spinning cone cavity 18, and is fed into the yarn exit channel 42. The wound fiber 26a travels around the spinning cone edge 16 during the rotational cycle 50, in which case it slides into the asymmetric recesses along the long side 12, thereby performing a first acceleration. Upon contact with the smallest part of the asymmetric recess 10, the wound fiber 26a is lifted by the short side 14. This allows further motion to be imparted to the rotational cycle motion.

[0051] In this case, the imparted motion is, in particular, vibration with respect to at least one outer surface 20 or spinning cone cavity surface. In this case, a concave inner surface 17 can be formed, in particular as shown in Figures 4A and 4B. The motion has, in particular, a radial component. In this case, the radial component R originates, in particular, from the axis of symmetry 34. As described above, at least a portion of the wound fibers 26a interacting with the asymmetric recess can be lifted at least temporarily from at least one of the aforementioned surfaces. This can result in striking motion of the wound fibers 26a, in particular when the wound fibers 26a reappear on at least one surface. This motion, which occurs radially outward or radially inward, can be described as vibrational motion. In particular, the spinning cone 100 is cleaned by the striking of the surface by the wound fibers 26a.

[0052] Figure 1B shows the corresponding spinning cone tip 110 of the spinning cone 100, which is provided with a symmetrical recess 15. In the symmetrical recess 15, each side 13 is formed identically. In this case, the functional principle of the symmetrical recess 15 is equivalent to that of the asymmetrical recess 10, which is described in detail with reference to Figure 1A. In this case, the symmetrical recess 15 can be manufactured more easily. The symmetrical recess 15 can also be used when it is not necessary to provide additional acceleration by the long side 12.

[0053] Figure 2 shows a schematic of the functional principle of part of the air jet spinning nozzle 30 of the air jet spinning apparatus 24 of an air jet spinning machine, the air jet spinning nozzle 30 having a spinning cone 100 including a spinning cone tip 110. In this case, the wound fiber 26a moves clockwise around the spinning cone tip 110 in a rotational cycle 50 along the rotational circulation direction U (not shown in the plan view). A fiber guide 29 can also be positioned around an axis of symmetry 34 (not shown here; see Figures 3A and 3C). In this case, the fiber guide 29 can be positioned and designed to align the supplied fiber and feed it into the spinning cone 100. During the rotational cycle 50 described, an acceleration zone 28 can be formed. In this acceleration zone, the wound fiber 26a in particular is accelerated, for example, by interacting with one of the recesses 10, 15 mentioned above. As a result, the wound fiber 26a can be lifted from the outer surface 20, at least temporarily. In that case, when the wrapped fibers 26a come into contact with the outer surface 20 or the inner surface of the spinning cone cavity 18 again, deposits are removed in particular, thereby improving cleaning during operation.

[0054] After the wound fibers 26a have moved beyond the spinning cone edge 16 into the spinning cone cavity 18, the wound fibers 26a can be spun together with the core fibers, thereby forming a yarn 26b, which enters the yarn exit channel 42 and can be drawn out from the air jet spinning nozzle 30 through thereafter. In this case, the yarn exit channel 42 may differ from the spinning cone side region 25 in terms of the material of particular choice, and is particularly located within the spinning cone core 27.

[0055] Figure 3A shows a schematic side view of one embodiment of a spinning cone 100 having a spinning cone tip 110 including a symmetrical recess 15. Figure 3B shows a schematic side view of one embodiment of a spinning cone tip 110 having an asymmetrical recess 10. Figure 3C shows a schematic angle diagram related to Figures 3A and 3B.

[0056] In this case, Figure 3A schematically shows a side view of one embodiment of the spinning cone 100, which has a spinning cone tip 110 having a symmetrical recess 15. As previously mentioned, the sides 13 of equal length are arranged to form the corresponding symmetrical recess 15. In this case, it can be understood that the recess is formed by removing material from the height of the spinning cone edge 16 at the location of the symmetrical recess 15. For example, a notch can be formed.

[0057] In that case, the spinning cone tip 110 including the symmetrical recess 15 was described in detail with reference to Figure 1B. In Figure 3A, the arrangement of the axis of symmetry 34 is particularly clear. The spinning cone 100 has, in particular, the spinning cone tip 110, the spinning cone body 120, and the spinning cone base 36. In that case, the axis of symmetry 34 is designed and positioned such that an axis parallel to the axis of symmetry 34 divides the symmetrical recess 15, and an equal angle exists between this axis and the two similar sides 13.

[0058] This is not particularly true in embodiments that include an asymmetrical recess 10, as shown in Figure 3B. As shown in Figure 3C, a particularly steep angle 37 is formed between the short side 14 and the axis parallel to the axis of symmetry 34 (for simplicity, these axes will be treated as the same in the following designation). In that case, a particularly flat angle 38 is formed between the long side 12 and the axis parallel to the axis of symmetry 34.

[0059] As outlined in Figure 3A, the spinning cone tip 110 can be mounted on the spinning cone 100 by the mounting edge 22. In this case, the spinning cone tip 110 can be made particularly interchangeable. This allows the spinning cone tip 110 shown in Figure 3A to be replaced with the spinning cone tip 110 shown in Figure 3B. This makes it particularly quick and easy for the user to switch between the two functions.

[0060] Figure 4A shows a schematic cross-sectional view of one embodiment of the spinning cone tip 110. Figure 4B shows a cross-sectional view of one embodiment of an insert having a concave inner surface 17 including a structured surface.

[0061] Figure 4A shows a cross-sectional view of one embodiment of the spinning cone 100, which in particular has a concave inner surface 17. Within this concave inner surface 17, in particular, inner recesses 11 are arranged. In this case, these do not penetrate the outer surface 20. In this case, they perform the functions and characteristics described in particular with respect to the symmetrical recesses 15 and asymmetrical recesses 10 with reference to Figures 1A and 1B. In this case, the inner recesses 11 can be configured to impart striking motion to the wound fibers 26a (or the region of the wound fibers 26a). In this case, the region of the wound fibers 26a is subjected to striking motion transmitted along the inside of the spinning cone cavity 18. This imparts striking motion to the movement of the wound fibers 26a on the inside, particularly within the concave inner surface 17.

[0062] Figure 4A shows, in particular, that the concave inner surface 17 has a height h2. In this case, the height h1 is the height of the spinning cone tip 110 in particular. As already described with reference to Figure 3A, the axis of symmetry 34 also extends through the spinning cone 100 and therefore through the spinning cone tip 110. The spinning cone cavity 18 has an outer diameter D on the inlet slope. In this case, the aforementioned radial direction R is also shown, which extends particularly perpendicularly outward from the axis of symmetry 34.

[0063] The concave inner surface 17 of the spinning cone cavity 18 is particularly adjacent to a yarn exit channel 42. The yarn exit channel may extend in the lower region of the spinning cone body 120, for example, in the transition region 49. A wider yarn guide region 45 may extend thereafter. In this case, the yarn exit channel 42 is designed to allow the formed yarn 26b to be fed out of the air jet spinning nozzle 30 by a rotational cycle 50 in the rotational cycle direction U, as shown and described in relation thereto in Figure 2, see also Figure 2. The transition region 49 and the adjacent wider yarn guide region 45 reduce frictional resistance as the yarn 26b slides through the spinning cone 100. For simplicity' sake, the spinning cone 100 is shown cut off at the cut edge 48.

[0064] Figure 4B illustrates a concave inner surface 17 with a helical shape as a surface structure 19. In this case, the wound fibers 26a flowing into this concave inner surface 17 of the spinning cone cavity 18 are guided through the helical shape. This improves the guidance of the wound fibers 26a, which also improves spinning quality. In this case, the concave inner surface 17 can be inserted into the spinning cone tip 110 by an exemplary embodiment of the concave spinning cone insert 23 shown. In this case, the spinning cone insert 23 can be placed on the spinning cone tip 110, particularly via the mounting surface 21. Fixation can be performed by a locking device 44, which ensures that the concave spinning cone insert 23 does not come off during the operation of the spinning cone 100.

[0065] Figure 5 shows a schematic diagram of a method 200 for cleaning a spinning cone 100. The method 200 for cleaning a spinning cone 100 includes, in particular, the step of placing a wound fiber 26a on the spinning cone 100. The method includes, in particular, performing a rotational cycle 50 of the wound fiber 26a 220. In this case, the rotational cycle is performed in particular around the axis of symmetry 34 of the spinning cone 100. The method includes, in particular, a step 230 of interacting with the wound fiber 26a. In this case, the interaction 230 is performed in particular with at least one interfering device during a complete rotational cycle 50. The interfering device may be a correspondingly described symmetrical recess 15 or an asymmetrical recess 10. In this case, the interaction 230 is configured to generate motion, in particular vibration 240, onto the motion of the wound fiber 26a interacting with the interfering device.
