Description

[0001] The invention relates to a winding machine for a musical string according to claim 1.

[0002] Some musical strings consist of only a single wire. However, most musical strings have a load-bearing core wrapped with at least one non-load-bearing winding element, which is wound helically around the core during the string's manufacture. This winding process takes place in or on a specially designed machine. This machine has two opposing clamping devices to which the two ends of the core are attached, rotating the core around its longitudinal axis for the winding process. The winding element is tensioned and wound around the rotating core in a helical pattern. This is achieved by moving or shifting the winding element parallel to the core's longitudinal axis.

[0003] CN 102 568 447 A describes a machine for the manufacture of musical strings, but does not show a guide device with three wheels, each of which is rotatably mounted parallel to the axis of rotation of the string core.

[0004] US Patent 4,338,772 A describes a device for winding strings. Although this device has several cylinders with axes of rotation parallel to the tailpiece axis, it is not a guide device for the winding process.

[0005] US 584,708 A describes a winding machine in which the string holder is guided on both sides next to the current winding point. It is pulled into a receptacle by the winding element. The winding point itself, however, remains unobstructed.

[0006] US Patent 3,990,220 A describes a winding machine in which the winding process takes place within a round opening, with the winding element also being fed through a closed round opening.

[0007] The object of the invention is to provide a winding machine for a musical string of the type mentioned above, with which the sound and playability of the musical string, in particular via its length, and therefore its sound and playability when playing, especially in different positions, can be predictably influenced and / or adjusted during or through the manufacturing process.

[0008] According to the invention, this is achieved by the features of claim 1.

[0009] This allows the sound and playability of the musical string to be predictably influenced and / or adjusted during or through the manufacturing process. This expands the possibilities for adjusting, specifying, or adapting the sound and playability of a musical string during or as a result of its production, independent of the materials used, its construction, and / or its dimensions. Therefore, it is not necessary to change the materials, construction, and / or dimensions to alter the sound and / or playability of the musical string.

[0010] The invention further relates to a method for manufacturing a musical string according to the preamble of claim 9.

[0011] The invention therefore further aims to selectively influence the sound of a musical string by means of the method of its manufacture.

[0012] According to the invention, this is achieved by the features of claim 9.

[0013] The advantages of the procedure correspond to the advantages of the aforementioned generic term.

[0014] The dependent claims relate to further advantageous embodiments of the invention.

[0015] The invention is described in more detail with reference to the enclosed drawings, in which only preferred embodiments are shown by way of example. These show: Fig. 1 a schematic diagram of a winding machine for the production of a musical string; Fig. 2 a floor plan of the winding machine according to Fig. 1 ; Fig. 3 a first preferred embodiment of a guide device together with a string core and a first winding element during the winding process in an axonometric view; Fig. 4 the order according to Fig. 3 in a first floor plan from a first line of view; Fig. 5 the order according to Fig. 3 in elevation; Fig. 6 the order according to Fig. 3 in a second floor plan from a second viewing angle; and Fig. 7 the order according to Fig. 3 in side view.

[0016] The Figs. 1 and 2 show a preferred embodiment of a winding machine 1 for a musical string 2, comprising a first rotatable clamping device 4 and a second rotatable clamping device 5, wherein the first clamping device 4 and the second clamping device 5 are configured for clamping a string core 7 of the musical string 2 and for rotation about a clamping device rotation axis 6 in a direction of rotation 28, further comprising a feeding device 11 for feeding at least one first winding element 13 in a first feeding direction 15 to the string core 7 during a winding process, further comprising a guide device 16 for predefinable, section-wise guiding of the string core 6, wherein the guide device 16 together with the feeding device 11 is movable parallel to the clamping device rotation axis 6 between the first clamping device 4 and the second clamping device 5, wherein the feeding device 11 and the guide device 16 are configured and interact such that at every point in time during the winding process an actual winding point 17 is formed in the guide device 16,where the first winding element 13 – to form a first winding layer 55 – begins to be wound around the string core 7, wherein the guide device 16 has a first cylinder 47 rotatably mounted about a first axis of rotation 42, a second cylinder 48 rotatably mounted about a second axis of rotation 43, and a third cylinder 49 rotatably mounted about a third axis of rotation 44, wherein the first, second, and third axes of rotation 42, 43, 44 are each arranged parallel to the clamping device axis of rotation 6, and wherein the first, second, and third cylinders 47, 48, 49 are arranged relative to each other and have such dimensions that they together form a stable position for the string core 7 at the winding point 17.

[0017] This allows the sound and playability of the second musical string to be predictably influenced and / or adjusted during or through the manufacturing process. This provides expanded possibilities for adjusting, defining, or adapting the sound and playability of a second musical string during or as a result of its manufacture, independent of the materials used, its internal structure, and / or its dimensions. Therefore, it is not necessary to change the materials, internal structure, and / or dimensions to alter the sound and / or playability of the second musical string.

[0018] In known manufacturing methods on previously used winding machines, the deformation and / or deflection of the string core at the current winding point 17, which can also be referred to as the winding point, cannot be specifically controlled or adjusted. During winding, the string core 7 and the first winding element 13 are deformed. These deformations are largely elastic and, depending on the magnitude of the tension force of the string core 7 and the magnitude of the initial tensile force 15 on the first winding element 13, also plastic. This lateral deflection, in conventional manufacturing methods and known machines, depends on the tension force on the string core 7 and the initial tensile force 14 on the first winding element 13.This deformation is further influenced by the angle between the approaching first winding element 13 and the clamping device rotation axis 6, as well as by the position of the current winding point 17 between the two clamping devices 4, 5.

[0019] Using the winding machine 1, this deformation can be preset independently of the aforementioned parameters. The deformation and / or deflection of the string core 7 or the musical string 2 during the manufacturing process can be preset on the winding machine 1 according to the invention without changing the tension force on the string core 7 and / or the initial tension force 15 on the first winding element 13 and / or the angle between the tapered first winding element 13 and the clamping element axis of rotation 6. Furthermore, the deformation and / or deflection can also be preset independently of the position of the current winding point 17 between the two clamping elements 4, 5. This makes it possible to produce musical strings with a predetermined sound and playability.

[0020] This allows the bending stiffness of the finished music string 2 to be predictably influenced. This allows the overtone behavior of the vibrating music string 2 to be predictably adjusted.

[0021] This allows the lateral deflection of the string core 7 from the tensioning device's axis of rotation 6 to be very finely adjusted at the spinning point or the current winding point 17. This also essentially prevents this deflection. Preventing this deflection has a direct influence on the winding process and the vibrational characteristics of the manufactured musical string 2. This enables particularly precise winding of the first winding element 13, as the string core 7 cannot yield unpredictably to the tension 14. This has proven especially advantageous when the tension on the first winding element 13 is varied along the length of the string core 7.

[0022] In the winding machine 1 in question, the string core 7 is not bent, or only slightly bent, during the winding process, thus preventing any return to its original position. This reduces the occurrence of irregular tension in at least one winding layer.

[0023] The winding machine 1 in question allows for more precise winding. This enables the targeted and repeatable formation of a winding layer in which the adjacent turns of the first winding element 13 touch but are not pressed against each other. This allows the first winding element 13 to be produced with a predefinable and highly repeatable distance between the individual turns. This, in turn, allows for the precise adjustment of the internal damping of the music string 2. The internal damping of the music string 2 can be increased to a predefinable degree. This significantly influences the vibration behavior of the music string.

[0024] When sound is produced by bowing, the music string 2 is set into a sawtooth vibration. As can be seen in an FFT, for example, each sawtooth is composed of many sine waves with different frequencies, with the high-frequency vibrations forming the tip of the sawtooth. The tip of the sawtooth directly determines the proportion of different high-frequency vibrations. This sawtooth tip can be shaped as needed by changing the contacts or contact forces between the adjacent windings. This allows for the direct generation of significantly clearer and more distinct high-frequency harmonic overtones. The manufacturing process on the winding machine 1 therefore has a direct influence on the playing and tonal characteristics of the music string 2.

[0025] Some instruments of the violin family produce a so-called wolf tone when excited in certain frequency ranges. The occurrence of a wolf tone causes a breakdown of the regular vibration of the fundamental tone, resulting in an irregular, uncontrollable sound. In the wolf tone range, an instrument is very difficult, if not impossible, to play. The tendency to produce a wolf tone is a characteristic of an individual instrument and not a characteristic of a specific type or genus of instruments. Therefore, not all string instruments exhibit one or more wolf tones. If an instrument, especially a violin or cello, exhibits a very pronounced wolf tone characteristic, this can significantly reduce the instrument's monetary value.

[0026] In addition to the behavior, especially the resonance behavior, of the affected instrument, the occurrence of the wolf tone or its "strength" or "pronouncement" can be influenced by the music string 2, which produces the sound with the relevant fundamental tone.

[0027] With the winding machine 1 in question, a musical string 2 can be specifically produced with which - in a correspondingly affected instrument - the occurrence of a wolf tone can be completely prevented or at least its "pronunciation" can be significantly reduced.

[0028] During the manufacturing process in the winding machine 1 in question, the internal damping of the musical string 2 can be preset within a predetermined frequency range, and in particular increased to such an extent that the instrument is damped in this range to such an extent that no wolf tone occurs, or if it does, it is only relatively weak. It should be noted that the relevant frequency ranges are very similar for different types of stringed instruments. For violins, this is the range between 450 Hz and 550 Hz, especially the range between B2 and C2.

[0029] The Figs. 1 and 2 The schematic representations of a physical winding machine 1 for the production of a musical string 2 are shown. Figs. 3 to 7Figure 16 shows a preferred embodiment of the guide device. The proportions shown do not necessarily correspond to the intended actual proportions. For better understanding, individual parts may be shown in a greatly enlarged view or with significantly exaggerated proportions.

[0030] The winding machine 1 is designed and constructed for winding a string core 7 during the manufacture of musical strings 2. A specific musical string 2 is intended for use on a particular type of musical instrument. The winding machine 1 is particularly intended for the manufacture of musical strings 2 for plucked or bowed string instruments. Preferably, the winding machine 1 is not intended for the manufacture of musical strings 2 for instruments that have a separate string 2 for each note and that are not plucked by the musician, but rather pressed against a fingerboard with their finger to produce different pitches. This applies in particular to the piano, the harpsichord, the zither, the harp, and similar instruments. Musical strings 2 for such instruments differ significantly in design from musical strings 2 for plucked or bowed string instruments.Furthermore, these strings also exhibit significantly different requirements, as the respective instruments and the excitation are entirely different. Due to these differences in musical string 2, the manufacturing processes and consequently the machines used to produce them also differ from those designed for the production of musical string 2 for plucked or bowed instruments.

[0031] The winding machine 1 has a machine bed 8. In its basic design, the winding machine 1 resembles a lathe, but exhibits some significant differences. In addition to the machine bed 8, the winding machine 1 has a straight guideway 9 on which a carriage 10 is longitudinally displaceable. Parallel to the guideway 9, the winding machine 1 preferably has at least one clamping guideway 32.

[0032] The winding machine 1 has two rotatable clamping devices 4 and 5, which are arranged opposite each other in or on the winding machine 1. The first clamping device 4 and the second clamping device 5 have a common clamping device axis of rotation 6. Both the guide track 9 and the clamping device guide track 32 are arranged parallel to the clamping device axis of rotation 6.

[0033] The first clamping device 4 and the second clamping device 5 are designed and configured for fastening or clamping a string core 7 of the musical string 2. In a simple embodiment, the first and second clamping devices 4, 5 are designed as hooks.

[0034] The first clamping device 4 and / or the second clamping device 5 are provided for predefinable clamping of the string core 7. At least one of the two clamping devices 4, 5, is arranged on an independent clamping device slide 33, which is longitudinally displaceable on a clamping device guide track 32 arranged parallel to the clamping device rotation axis 6. The clamping device slide 33 can also have a locking device to hold its position on the clamping device guide track 32. The first clamping device 4 is preferably fixedly connected to the machine bed 8.

[0035] The winding machine 1 has at least one drive motor which drives the two clamping devices 4, 5 and is preferably connected to them via a gearbox. In particular, the winding machine 1 has two drive motors, preferably with rotational angle control, each of which drives one of the clamping devices 4, 5. The two clamping devices 4, 5 are driven such that they cause a clamped string core 7 to rotate about its longitudinal extent. If a first winding layer comprising the first winding element 13 is already arranged on the string core 7 and a further winding layer is to be arranged around or on the first winding layer, then the assembly of string core 7 and the first winding element 13 arranged on it will, of course, be set into rotation about its longitudinal extent. The string core 7 orAn intermediate product in the manufacture of the musical string 2 is not twisted or warped during rotation. The rotation takes place in a direction 28, which is in . Fig. 3 marked.

[0036] In the production of the musical string 2, the rotating string core 7 is helically wound or encased with at least one first winding element 13. For the controlled dispensing of the first winding element 13 during the winding process, the winding machine 1 has a feed device 11, which is arranged on the carriage 10. Preferably, the first winding element 13 is arranged on a spool 34, which is connected to the feed device 11 or the carriage 10, and is taken from or unwound from this spool 34 during production.

[0037] The feeding device 11 has a discharge section 12 against which the first winding element 13 rests and is pulled off for predetermined or controlled dispensing. The discharge section 12 is the last point where the first winding element 13 touches the feeding device 11 as it approaches the string core 7. The discharge section 12 is preferably a rotatably mounted roller. Figs. 1 and 2 The image shows an example of such a role. It can also be arranged in other positions, in particular at different angles to the clamping element's axis of rotation 6.

[0038] At the start of the production of the musical string 2, one end of the first winding element 13 is connected to a string core 7. This is preferably done near the first tensioning device 4. The first winding element 13, now attached to the string core 7, is then tensioned with a predetermined tensile force 14, and the string core 7 is set into rotation. The rotation moves the first winding element 13 away from its source, preferably unwinding it from the spool 34. The predetermined tensile force 14 can be achieved and / or adjusted, for example, by a resistance or brake on the spool 34, so that the first winding element 13 is unwound from the spool 34 with a certain force, hence the tensile force 14. The higher the resistance, the greater the tensile force 14.

[0039] By combining the rotation of the string core 7 and the movement of the winding device 11 essentially parallel to the clamping element's axis of rotation 6, the string core 7 is wound helically or spirally by the first winding element 13 during the winding process. The contact point where the first winding element 13 touches the string core 7 and begins to be wound around it, and consequently the point where the tensile force 14 acts on the string core 7, is referred to as the winding point 17 or current winding point 17.

[0040] Due to the first winding element 13, which now pulls laterally on the string core 7, the string core 7 would be deflected or bent or deformed, as is known from the classical mechanics of the carrier on two support points.

[0041] The winding machine 1 has a guide device 16 for the predefinable, section-by-section guidance of the string core 7. "Guide" is understood in particular to mean that the degree of lateral deflection or bending of the string core 7 due to the tensile force 14 can be predetermined or controlled, preferably prevented.

[0042] During the winding process, the guide device 16 moves parallel to the clamping device's rotary axis 6 together with the feed device 11. The feed device 11 and the guide device 16 are designed and arranged such that the winding point 17 is located within the guide device 16. Lateral deflections of the string core 7 during the winding process, caused by the tensile force 14, are now limited by the guide device 16. The guide device 16 therefore acts as a support for the string core 7 at the current winding point 17.

[0043] The guide device 16 has three cylinders, a first cylinder 47, a second cylinder 48 and a third cylinder 49.

[0044] Each of the three cylinders 47, 48, 49 is a body with a diameter, an axis of rotation, a length in the direction of the clamping device axis of rotation 6 and is made of a material.

[0045] The first cylinder 47 has a first diameter, a first axis of rotation 42, and a first length. The second cylinder 48 has a second diameter and a second axis of rotation 43. The third cylinder 49 has a third diameter and a third axis of rotation 44. The three axes of rotation 42, 43, 44 are each arranged substantially parallel to the axis of rotation of the clamping device 6.

[0046] Each of the three rotatably mounted cylinders 47, 48, 49 is preferably not actively driven. Rotations occur due to contact with the string core 7 or the first winding layer 13 or further winding layers. Figs. 1 and 2 schematically show a corresponding storage arrangement, wherein in Fig. 1 The connecting axes with cylinders 47, 48, 49 are not shown.

[0047] It is intended that the first cylinder 47, the second cylinder 48, and the third cylinder 49 are arranged relative to each other and have such dimensions that together they form a stable position for the string core 7 at the winding point 17. Stable, as is known from classical mechanics, means that the string core 7 returns to its resting position after a deflection.

[0048] As shown in the figures and viewed along the clamping device's axis of rotation 6, the second cylinder 48 is arranged between the first cylinder 47 and the third cylinder 49. This only concerns the basic positioning in one direction, but not that they physically form a single cylinder. It has proven advantageous if the second cylinder 48—viewed along the clamping device's axis of rotation 6—is arranged substantially adjacent to the first cylinder 47, and / or if the third cylinder 49 is arranged substantially adjacent to the second cylinder 48—viewed along the clamping device's axis of rotation 6. "Substantially adjacent" means that they are arranged so close to each other that independent rotational movements of the individual cylinders 47, 48, 49 are still possible without any contact or friction between them.In particular, the gaps between the adjacent cylinders each have a width that is less than the width of the first winding element 13. It may be provided that a lubricant is arranged in the gaps.

[0049] Preferred and those in Figs. 3 to 7 As shown, the first axis of rotation 42 is essentially the third axis of rotation 44. These are arranged essentially parallel to the clamping device axis of rotation 6. In a first direction 71, they have a first distance 73 from the clamping device axis of rotation 6. The position of the second axis of rotation 43 has a second distance 74 from the clamping device axis of rotation 6 in a second direction 72. These values ​​refer to a plane normal to the clamping device axis of rotation 6. The two directions 71, 72 differ from each other and are distinguished in Fig. 5The diagram shows the positions 71, 72 and the distances 73, 74. Preferably, the two distances 73, 74 may also differ. In particular, however, they are of the same length. When selecting the specific positions 71, 72 and distances 73, 74, the diameters of the cylinders 47, 48, 49 must also be taken into account to ensure a stable position for the string core.

[0050] Each of the three cylinders is a body made of a material. Preferably, all three cylinders 47, 48, 49 are made of the same material. Metals, especially steel, bronze, brass, and titanium alloys, are primarily considered as materials. Alternatively, they can also be made of a plastic. Furthermore, cylinders made of a ceramic material have proven advantageous.

[0051] The guide device 16 has a length – viewed in a direction along or parallel to the clamping device's axis of rotation 6 – which is composed of the first length of the first cylinder 47, the second length of the second cylinder 48, and the third length of the third cylinder 49. The length of the guide device 16 is preferably between 1% and 14% of the scale length of the musical string 2 to be manufactured. For example, with a scale length of 1100 mm, this length can be essentially 11 mm, or approximately 1%. With a scale length of 215 mm, it can be essentially 30 mm, or approximately 14%.

[0052] In particular, it is provided that the cylinders 47, 48, 49 have predefinable surface roughnesses, or that the surface roughnesses are not uncontrolled random properties. It is especially preferred that the first surface roughness of the first cylinder 47, the second surface roughness of the second cylinder 48, and the third surface roughness of the third cylinder 49 are designed or selected such that static friction exists between the string core 7 or the first winding layer 55 already applied to it and the guide device 16, i.e., the three cylinders 47, 48, 49. This causes them to rotate along with the string core 7. The string core 7 or the first or subsequent winding layers 13 are therefore not pulled across a surface with contact with the body and thus not altered.

[0053] The surface roughness depends in particular on the type of manufacture of the cylinders 47, 48, 49, for example whether they are specifically ground down, but can also depend on the material, since especially low surface roughness cannot be achieved with every material.

[0054] The second cylinder 48 can have an uninterrupted path. It has proven advantageous for guiding the first winding element 13 and forming the current winding point 17 if the second cylinder 48 has a corresponding guide element. In particular, it has proven advantageous for the second cylinder 48 to have a recess 75 in which the first winding element 13 is guided.

[0055] To support a safe advance of the first winding element 13 and the current winding point 17, it is provided in particular that a first transition 77 between the recess 75 or the corresponding inner surface and a second outer surface 79 of the second cylinder 48 is a stop for the first winding element 13 and is designed accordingly.

[0056] To ensure that the first winding element 13 is fed undamaged to the string core 7, it is further preferably provided that a second transition 81 between the recess 75 and a second outer surface 79 of the second cylinder 48 has at least a rounded circumferential area 82.

[0057] The guide device 16 is connected to the feed device 11 by means of a fastening device 39. This fastening device 39 can be designed as a stationary machine component.

[0058] With familiar strings on bowed and plucked instruments, the sound and handling / playability generally change when the musician moves their finger from a so-called low action (corresponding to a lower pitch and consequently a relatively long vibrating section of the string) to a so-called high action (corresponding to a higher pitch and a relatively short vibrating section of the string). Instruments of the violin family always have a fingerboard over which the string runs. The distance between the fingerboard and the string changes along the string's path from the nut and bridge of the instrument. At the nut, this distance is relatively small. At the end of the fingerboard opposite the bridge, this distance is significantly larger, usually two to three times the distance at the nut.These varying distances influence the sound, handling, and excitation characteristics of the musical string, and are a major reason for the different properties of different fundamental tones. Due to these varying distances, when the string is pressed against the fretboard, the string is stretched differently depending on where on the fretboard it is plucked.

[0059] To compensate for this effect, individual parts of stringed and plucked instruments are adjusted accordingly. In particular, with instruments of the violin family, the fingerboard is often shaped differently along its length. This is called fingerboard hollowing. This adjustment must be made individually for each instrument by a luthier. This is a time-consuming, complex, and expensive process for the luthier.

[0060] In a further development of the invention, it can be provided that the distance between the guide device 16 and the clamping device rotary axis 6 is adjustable. The winding machine 1 has an adjustable or adjustable and preferably force-controllable and / or displacement-controllable fastening device 39.

[0061] The fastening device 39 is designed in such a way that the relevant distance or normal distance can be continuously and predictably adjusted along the length of the string core 7. In particular, such that this distance follows a predictable profile.

[0062] This allows the production of musical strings 2 which, at different vibrating lengths (i.e., when played in different positions), exhibit a sound and / or playability that differs considerably from conventionally manufactured musical strings 2. This is because different deflections can be achieved during production in the winding machine 1 than are possible with known manufacturing methods. Thus, a musical string 2 can be produced which, at specific fretted lengths or positions, exhibits predefinable tonal characteristics and / or specific playability.

[0063] This allows for the creation of musical strings that are easily playable even on an instrument with a simple fretboard, i.e., a fretboard without a hollow cut. This can positively influence the sound of simpler and less expensive instruments. As a result, the costly work of an instrument maker can be avoided.

[0064] This allows the contact forces between adjacent windings to be very precisely adjusted and, above all, predictably varied along the length of the music string 2. This has a direct influence on the bending stiffness of the vibrating length of the music string 2. By adjusting the contact forces, the bending stiffness can be adapted to the vibrating string length, i.e., changed along the length of the music string 2.

[0065] The fastening device 39 includes a corresponding actuator. The actuator is, in particular, an electrically and / or pneumatically operated mechanical positioning unit. The electrically operated positioning unit is particularly comparable to a so-called servo from the field of model aircraft. A preferred pneumatically operated positioning unit is, for example, a pneumatic guide cylinder, a pneumatic piston cylinder, and / or a servo-pneumatic positioning system.

[0066] This allows the distance of the guide device 16 to the clamping device rotation axis 6 to be set and predefinably changed.

[0067] According to a preferred embodiment of the actuator, it comprises both a pneumatic actuating unit and an electric actuating unit, the electric actuating unit being arranged on the pneumatic actuating unit. This allows for coarse adjustment using the pneumatic actuating unit, in which the guide device 16 is moved within a predefinable range around a target point. Subsequently, a so-called fine adjustment is performed using the electric actuating unit. The guide device 16 is thereby moved very precisely to the desired position.

[0068] In a method for manufacturing a musical string 2, in particular with a winding machine 1 as described, it is provided that that a first end of a string core 7 of the musical string 2 is attached to a first clamping device 4, wherein a second end of the string core 7 is attached to a second clamping device 5, wherein a predetermined section of the string core 7 is guided in a guide device 16 with a first cylinder 47 having a first axis of rotation 42, a second cylinder 48 having a second axis of rotation 43 and a third cylinder 49 having a third axis of rotation 44, which are arranged relative to each other and have such dimensions that they together form a stable position for the string core 7, wherein in a winding process at least one first winding element 13 is fed to the string core 7 in a first feeding direction 15 along the second cylinder 48 by means of a feeding device 11, wherein the feeding device 11 and the guide device 16 interact in such a way thatthat at each point in the winding process a current winding point 17 is formed in the guide device 16, at which the first winding element 13 begins to be wound around the string core 7, wherein the first winding element 13 is tensioned with a predefinable tensile force 14, wherein the clamping means 4, 5 are rotated about a clamping means rotation axis 6, and wherein the guide device 16 together with the feed device 11 is moved parallel to the clamping means rotation axis 6 between the first clamping means 4 and the second clamping means 5.

[0069] In a preferred method for manufacturing a musical string 2 using an adjustable fastening device 39, it is provided that the respective normal distance of the guide device 16 to the clamping means rotation axis 6 is continuously changed.

[0070] The following are principles for understanding and interpreting the disclosure in question.

[0071] Characters are usually introduced with an indefinite article "ein, eine, eines, einer". Unless the context indicates otherwise, "ein, eine, eines, einer" should therefore not be understood as a numeral.
