Description

[0001] Method for producing a musical string

[0002] The invention relates to a method for producing a musical string according to the preamble of patent claim 1.

[0003] For centuries, musical strings made from sheep gut have been used for string instruments. However, gut strings are not suitable for all types of strings due to their strength and are subject to fluctuations in tuning stability, as moisture absorption changes the tension of the strings.

[0004] Furthermore, it is well known that the specifications of pitch, scale length, and string tension are of particular importance for a musical string, especially for stringed instruments. Today's more common musical strings feature a string core and one or more windings, called coil layers. The string core is loaded when the string is tensioned and carries or absorbs the tuning weight, whereas the coil layer increases the mass of the musical string.

[0005] The disadvantage is that the material mix or mix of different materials used in musical strings is influenced by the environmental conditions, which means that the properties of the musical string change over time.

[0006] The object of the invention is therefore to provide a method of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, with which a musical string can be created in an efficient manner which resembles the sound character of a natural gut string, is less sensitive to moisture absorption and has a high tuning stability.

[0007] According to the invention, this is achieved by the features of patent claim 1.

[0008] This offers the advantage of creating a musical string with consistent properties over an extended period of time. The fluid can be used to adjust the damping of the string's vibrational behavior. This allows, for example, the string's tonal character, such as brilliance and warmth, as well as its timbre variety, such as rich and complex or pure, to be maintained. This reduces corrosion on the string and its moisture absorption. This allows materials to be used in the production of the string that, without protection from environmental conditions, particularly heat or humidity, exhibit significant fluctuations in their properties.In summary, this makes it possible to create a musical string for a specific musical instrument and musician from a material mix that comes close to the sound character of a natural gut string and is as insensitive as possible to the environmental conditions.

[0009] The invention further relates to a musical string according to claim 11.

[0010] The invention therefore has the further object of providing a musical string of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, which resembles the sound character of a natural gut string, is less sensitive to moisture absorption and has a high tuning stability.

[0011] According to the invention, this is achieved by the features of patent claim 11.

[0012] The advantages of the musical string correspond to the advantages of the above-mentioned process.

[0013] The subclaims relate to further advantageous embodiments of the invention.

[0014] The invention will be described in more detail with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example. In the drawings:

[0015] Fig. 1 shows a first preferred embodiment of a musical string in longitudinal section,

[0016] Fig. 2 shows a second preferred embodiment of a musical string in longitudinal section,

[0017] Fig. 3 shows a third preferred embodiment of a musical string in longitudinal section, Fig. 4 shows a fourth preferred embodiment of a musical string in longitudinal section,

[0018] Fig. 5 shows a fifth preferred embodiment of a musical string in longitudinal section.

[0019] 1 to 5 show at least parts of preferred embodiments of a musical string 1 comprising a supporting string core 2 and a first winding element 3, wherein the first winding element 3 is wound in the form of a helical line around the supporting string core 2, wherein at least one hardenable fluid 5 is arranged between the first winding element 3 and the supporting string core 2, which hardenable fluid 5 is treated electromagnetically in a predeterminable manner.

[0020] Furthermore, a method for producing a musical string 1 comprising a supporting string core 2 and a first winding element 3 is provided, wherein the first winding element 3 is wound in the form of a helical line around the supporting string core 2, wherein at a first string core location 4 - viewed along the string core 2 - before winding the first winding element 3, a hardenable fluid 5 is applied in such a way that the hardenable fluid 5 is arranged between the first winding element 3 and the supporting string core 2 after winding the first winding element 3, and wherein after winding the first winding element 3, the first string core location 4 is thermally treated or electromagnetically irradiated for at least a predeterminable time to harden the fluid 5.

[0021] This results in the advantage that a musical string 1 can be created which exhibits consistent properties over an extended period of time. The damping of the vibration behavior of the musical string 1 can thus be adjusted using the fluid 5. This allows, for example, the sound character of the musical string 1, such as brilliance and warmth, as well as the variety of timbres, such as rich and complex or pure, of the musical string 1 to be retained. This can reduce corrosion on the musical string 1 and the moisture absorption of the musical string 1. This allows materials to be used in the manufacture of the musical string 1 which, without protection from environmental conditions, such as heat or humidity in particular, exhibit significant fluctuations in their properties.In summary, this makes it possible to create a musical string 1 for a specific musical instrument and musician from a material mix that comes close to the sound character of a natural gut string and is as insensitive as possible to the environmental conditions.

[0022] The preferred embodiments shown in Figs. 1 to 5 are depicted in simplified form. The proportions may not necessarily correspond to the intended actual proportions. For better understanding, individual parts may be shown in greatly enlarged views.

[0023] The musical string 1 according to the invention is intended for generating tone-producing vibrations. A specific type of musical string 1 is intended for use with a specific type of musical instrument and further comprises a tuning pitch and a so-called tuning weight as features. The tuning pitch indicates the fundamental pitch at which a portion of the musical string 1—between its end regions—of the length of the scale of the specific type of musical instrument vibrates when the musical string 1 is loaded with the tuning weight, thus tensioned, and naturally excited to vibration.

[0024] The musical string 1 according to the invention has a string core 2 which is provided and designed to absorb the load or tension to which the musical string 1 is exposed when stretched on a musical instrument.

[0025] Preferably, the string core 2 may comprise metal and / or a polymer, in particular a plastic.

[0026] Preferably, the string core 2 consists of metal or a polymer, in particular of a plastic.

[0027] Preferably, the string core 2 can be made of polyamide, preferably nylon or Perlon, or of polyester or of a polyaryletherketone.

[0028] Preferably, the string core 2 can be made of a chrome steel or a carbon steel.

[0029] The string core 2 preferably has a predeterminable plurality of core elements 10. The core elements 10 of the string core 2 are shown as examples in Figs. 1, 4 and 5.

[0030] Particularly preferably, the core elements 10 are formed from plastic fibers. The core elements 10 formed in this way then form a so-called fiber bundle core.

[0031] Preferably, it can also be provided that the string core 2 is designed as a rope, in particular as a wire rope.

[0032] Alternatively, the string core 2 can be formed from a single strand. The string core 2 can preferably be formed from a single wire or plastic strand.

[0033] It is provided that a first winding element 3 is wound around the supporting string core 2. According to the invention, the first winding element 3 is wound helically around the supporting string core 2. Preferably, the first winding element 3 forms a first winding layer.

[0034] Preferably, the first winding element 3 is wound from a first end of the supporting string core 2 to a second end of the supporting string core 2.

[0035] Preferably, the first winding element 3 consists of a metal, a metal alloy or a plastic.

[0036] If there is a gap, particularly a helical gap, or a small distance between adjacent turns of the first winding element 3 or between the adjacent turns of a first winding element 3 and a second winding element, it is preferably provided that the at least one curable fluid is arranged in this gap. As a result, the cured fluid bonds the adjacent turns.

[0037] According to a first preferred variant, the first winding element 3 comprises a metal selected from the group: aluminum, magnesium, iron, chromium, nickel, silicon, silver, gold, platinum, rhodium, ruthenium, rhenium, palladium, osmium, copper, tungsten, tantalum, manganese, molybdenum, wherein each of the substances mentioned can be provided as a pure substance in the technical sense, but also as a component of an alloy.Musical strings 1 have proven particularly advantageous in which the first winding element 3 is formed from at least one alloy selected from the group: steel, aluminum-magnesium alloys, aluminum-magnesium-manganese alloys, silver-copper alloys, silver-platinum alloys, silver-rhodium alloys, silver-palladium alloys, iron-chromium-nickel-silicon-aluminum alloys, beryllium alloy, phosphor bronze, iron-aluminum-chromium alloys, iron-chromium-aluminum alloys, aluminum-iron-chromium alloys, aluminum-silicon-chromium alloys. Steel is preferably steel comprising alloying components selected from the group: carbon, chromium, nickel, molybdenum, vanadium, manganese, tungsten, with particular preference being given to carbon steels (C content of 0.01% to 0.03%) and chromium-nickel steels (Cr content of 17% to 20%, Ni content of 8% to 10%).Furthermore, it can be provided that the first winding element 3 has a surface coating, wherein a coating with at least one metal, in particular brass, tin, nickel, and / or a plastic, in particular a polymer, can be provided. Preferably, it can be provided that a predeterminable number of coatings are arranged one above the other.

[0038] According to a second preferred variant, the first winding element 3 comprises a plastic selected from the group: polymers and / or aramid and / or PEK and / or PAEK and / or PEEK and / or PBT and / or polyester and / or nylon and / or polyethylene and / or PET and / or PEET and / or PES and / or PE and / or PP and / or POM and / or PTFE and / or PVDF and / or PVDC and / or HPPE and / or PA and / or PVC.

[0039] The first winding element 3 is preferably designed as a round wire or as a flat strip, in particular with a substantially rectangular cross-section and a predeterminable edge configuration. A first winding element 3 designed as a flat strip, which first winding element 3 is wound around the supporting string core 2, is shown by way of example in Fig. 2.

[0040] Preferably, the first winding element 3 is formed as a round wire. This is shown by way of example in Figs. 1, 3, and 5.

[0041] Preferably, the first winding element 3, in particular the first winding element 3 formed as a round wire, can be ground flat after winding around the supporting string core 2. This allows a substantially flat outer surface to be obtained. This can be seen by way of example in Fig. 4.

[0042] It can preferably be provided that the musical string 1 comprises a second winding element 8, which second winding element 8 is wound in the form of a helical line around the supporting string core 2 before the application of the first winding element 3, and that the at least one curable fluid 5 is applied between the first winding element 3 and the second winding element 8. When viewing a cross-section of the musical string 1, starting from the core, first the second winding element 8 and then the first winding element 3 are wound around the supporting string core 2. This allows the properties of the musical string 1 to be adapted even more individually to the musician and a specific musical instrument, since more freedom in the choice of materials results in the production of the musical string 1, whereby the advantages of the curable fluid 5 are nevertheless formed on the musical string 1.

[0043] The use of different materials for the production of the musical string 1 can preferably also be referred to as the use of a material mix. The musical string 1 can thus preferably comprise a material mix, in particular a material mix of different materials. For example, the string core 2 of the musical string 1 can be made of a specific polymer, such as nylon, and the first winding element 3 can be made of a specific metal, such as chrome steel.

[0044] Preferably, the musical string 1 can have a further winding layer in addition to the first winding layer. The further, in particular the second, winding layer is preferably formed from the second winding element 8.

[0045] Preferably, the second winding element 8 consists of a metal, a metal alloy or a plastic.

[0046] According to a first preferred variant, the second winding element 8 comprises a metal selected from the group: aluminum, magnesium, iron, chromium, nickel, silicon, silver, gold, platinum, rhodium, ruthenium, rhenium, palladium, osmium, copper, tungsten, tantalum, manganese, molybdenum, wherein each of the substances mentioned can be provided as a pure substance in the technical sense, but also as a component of an alloy.Musical strings 1 have proven particularly advantageous in which the second winding element 8 is formed from at least one alloy selected from the group: steel, aluminum-magnesium alloys, aluminum-magnesium-manganese alloys, silver-copper alloys, silver-platinum alloys, silver-rhodium alloys, silver-palladium alloys, iron-chromium-nickel-silicon-aluminum alloys, beryllium alloy, phosphor bronze, iron-aluminum-chromium alloys, iron-chromium-aluminum alloys, aluminum-iron-chromium alloys, aluminum-silicon-chromium alloys. Steel is preferably steel comprising alloying components selected from the group: carbon, chromium, nickel, molybdenum, vanadium, manganese, tungsten, with particular preference being given to carbon steels (C content of 0.01% to 0.03%) and chromium-nickel steels (Cr content of 17% to 20%, Ni content of 8% to 10%).Furthermore, it can be provided that the second winding element 8 has a surface coating, wherein a coating with at least one metal, in particular brass, tin, nickel, and / or a plastic, in particular a polymer, can be provided. Preferably, it can be provided that a predeterminable number of coatings are arranged one above the other.

[0047] According to a second preferred variant, the second winding element 8 comprises a plastic selected from the group: polymers and / or aramid and / or PEK and / or PAEK and / or PEEK and / or PBT and / or polyester and / or nylon and / or polyethylene and / or PET and / or PEET and / or PES and / or PE and / or PP and / or POM and / or PTFE and / or PVDF and / or PVDC and / or HPPE and / or PA and / or PVC.

[0048] Preferably, the second winding element 8 is designed as a round wire or as a flat strip, in particular with a substantially rectangular cross-section and a predeterminable edge formation.

[0049] Preferably, the first winding element 3 and / or the second winding element 8 can comprise a plurality of round wires or flat strips wound parallel to one another, side by side, around the supporting string core 2. These wound round wires or flat strips are wound simultaneously. For example, the first winding element 3 and / or the second winding element 8 can be formed from two flat strips, which are wound simultaneously from the first end of the string core 2 to the second end of the string core 2 around the supporting string core 2.

[0050] Preferably, during winding, a respective winding tangent of the round wires or flat strips can be parallel to each other.

[0051] Preferably, the second winding element 8 is formed between the first winding element 3 and the supporting string core 2. Preferably, the second winding element 8 is arranged between the first winding layer formed from the first winding element 3 and the supporting string core 2. This is shown by way of example in Figs. 4 and 5.

[0052] Preferably, the curable fluid 5 can be applied between the second winding element 8 and the supporting string core 2. Preferably, the curable fluid 5 can be applied by means of a spray nozzle or a spray gun or a brush. Preferably, as shown in Fig. 5, in the musical string 1, between the first winding element 3 and the second

[0053] The hardenable fluid 5 is applied between the first winding element 8 and the second winding element 8 and the supporting string core 2.

[0054] An applied curable fluid 5 can also be referred to as an applied curable fluid 5. Another term for applying can therefore also be "applying."

[0055] Preferably, the musical string 1 can have further winding elements in addition to the first winding element 3 and the second winding element 8.

[0056] It is provided that after the first winding element 3 is wound around the supporting string core 2, the first string core location 4 is thermally treated or electromagnetically irradiated for at least a predeterminable period of time. Preferably, the first string core location 4 is thermally treated or electromagnetically irradiated to achieve a predeterminable hardness of the hardenable fluid 5. According to a preferred embodiment, provision can be made for a thermal treatment to be carried out in addition to the electromagnetic irradiation.

[0057] According to a first preferred thermal treatment, the curable fluid 5 is cooled to a predetermined temperature, in particular to a temperature of 4 to 18 degrees, before being wound or wrapped with the first winding element 3. This thickens the curable fluid 5. After the winding process, the intermediate product of the musical string 1 to be produced is heated, whereby the viscosity of the curable fluid 5 is reduced to a predetermined extent and a targeted distribution of the curable fluid 5 occurs in the spaces between the string core 2 and the first winding element 3. In a subsequent process step, the curable fluid 5 is cured or solidified.

[0058] According to a second preferred thermal treatment, the curable fluid 5 is applied to the string core 2 and heated to a predetermined temperature together with the string core before the subsequent winding or wrapping process. The temperature depends in particular on the specific configuration of the curable fluid 5. This leads to a more even distribution of the curable fluid 5 on the musical string 1. After the winding process, the intermediate product of the musical string 1 to be produced is cooled.

[0059] In a third preferred thermal treatment, a curable fluid 5 is provided, which is designed such that crosslinking is activated by targeted heating in the curable fluid 5. Subsequent cooling leads to a predeterminable curing.

[0060] The curable fluid 5 may comprise a solvent. Alternatively, the curable fluid 5 may be solvent-free.

[0061] According to a fourth preferred thermal treatment, the curable fluid 5 necessarily comprises a solvent. Through predeterminable heating, the solvent can be deliberately released. This leads to the curing of the curable fluid 5.

[0062] Furthermore, according to a fifth preferred embodiment, the curable fluid 5 is designed as a highly viscous adhesive which is heated before the winding process in order to reduce the viscosity.

[0063] According to a sixth preferred embodiment, the curable fluid 5 contains at least two components, one of which is a hardener. The thermal treatment can activate the hardener and cause the curable fluid 5 to harden. Preferably, another of the at least two components can be a synthetic resin.

[0064] Preferably, the thermal treatment of the first string core location 4 can also be a cooling of the first string core location 4. This can be the case, for example, if a heated or warmed curable fluid 5 is applied and, after the application of this fluid 5, this fluid 5 is cooled to room temperature. The first string core location 4 is a location along the supporting string core 2. Fig. 1 shows, by way of example, a string core location 2 of the musical string 1, with reference number 4 pointing to a cross-section of the musical string 1. As a result, the curable fluid 5 can advantageously be applied particularly easily before the first winding element 3 is wound around the supporting string core 2, but also in one step during the winding process.

[0065] Hardness is defined as the resistance of a material to penetration by a harder body. Common hardness measurements, especially for polymers, include the Shore hardness measurement method or IRHD (International Rubber Hardness Degree).

[0066] Particularly preferably, it can be provided that the first string core location 4 is thermally treated or electromagnetically irradiated until the curable fluid 5 has reached a Shore A hardness of at least 10, particularly preferably of at least 20, in particular 40.

[0067] It can preferably be provided that the musical string 1 is electromagnetically irradiated for at least 3 seconds, in particular at least 20 seconds, in particular at least 30 seconds. This can stimulate the curable fluid 5 to harden or to harden it to a certain hardness. Preferably, a curable fluid 5 can be selected that requires only a very short time for the stimulation to harden the fluid 5. The above-mentioned time sequences are also preferably provided for the preferred additional thermal treatment.

[0068] Preferably, the electromagnetic radiation has a wavelength range between 10 nm and 400 nm, in particular between 100 nm and 400 nm, and / or is UV radiation.

[0069] It can preferably be provided that, after winding the first winding element 3, the first string core location 4 is irradiated with UV radiation for at least a predeterminable time to cure the fluid 5. This results in the advantage that a commercially available UV lamp can be used to irradiate the curable fluid 5, allowing the fluid 5 to be cured particularly easily. This allows the fluid 5 to be cured particularly easily during the production of the musical string 1.

[0070] A first preferred embodiment of UV radiation has a wavelength range between 380 nm and 315 nm. This is also referred to as UV-A.

[0071] A second preferred embodiment of UV radiation has a wavelength range between 315 nm and 280 nm. This is also referred to as UV-B.

[0072] A third preferred embodiment of UV radiation has a wavelength range between 280 nm and 100 nm. This is also referred to as UV-C.

[0073] A fourth preferred embodiment of UV radiation has a wavelength range between 10 nm and 100 nm. This is also referred to as EUV. EUV is the abbreviation for extreme UV.

[0074] Each of these four embodiments is advantageous for different areas of application and different fluids 5.

[0075] The electromagnetic radiation can also have a broadband wavelength range and / or be a combination of two, three, or four of the aforementioned embodiments. Preferably, the at least one fluid 5, or at least one fluid 5 of a plurality of fluids, comprises a UV-curing varnish. Particularly preferably, the fluid 5 is a gel varnish. Gel varnishes are used, for example, as nail polish. Another name for this is Shellac. Such gel varnishes have good, proven curing properties. Furthermore, it has been shown that cured gel varnishes have advantageous acoustic properties when used as fluid 5 in a musical string.

[0076] Preferably, it can also be provided that the musical string 1 is irradiated with a UV light flash. A UV light flash is a locally placed flash of ultraviolet light. This offers the advantage that a curable fluid 5 can be used, in which the UV light flash triggers a chemical reaction to cure the fluid 5. This makes it particularly easy to cure the fluid 5 even in places that are concealed from the UV light, for example, by the first winding element 3. The curable fluid 5 can preferably be an epoxy resin.

[0077] It can preferably be provided that the curable fluid 5 is applied to each string core location - viewed along the string core 2 - before winding the first winding element 3 such that the curable fluid 5 is arranged between the first winding element 3 and the supporting string core 2 after winding the first winding element 3. This allows the curable fluid 5 to be applied between the first winding element 3 and the supporting string core 2 in a particularly simple manner, since the curable fluid 5 is applied before the step of winding the first winding element 3 around the supporting string core 2.

[0078] It can preferably be provided that the application of the curable fluid 5 and the winding of the first winding element 3 around the supporting string core 2 are carried out in a single work step. This can further improve the workflow during the production of the musical string 1. For example, the supporting string core 2 can be clamped into a machine at both ends, wherein the two ends of the string core 2 are clamped to two rotatably mounted shafts of the machine, which two shafts run axially in a line, and an arm of the machine, which is movable from one end of the string core 2 to the other end of the string core 2, winds the first winding element 3 around the supporting string core 2, wherein the curable fluid 5 is applied or applied to the supporting string core 2 prior to winding, for example by means of a brush or by spraying, for example using a spray nozzle.For example, the brush or spray gun can be attached to the arm of the machine.

[0079] It can preferably be provided that the winding of the first winding element 3 around the supporting string core 2 and the thermal treatment or electromagnetic irradiation are carried out in a single work step. This can further improve the workflow for producing the musical string 1. Similar to the example described above, for example, the first winding element 3 can be wound around the supporting string core 2 by means of the machine, wherein after winding, the curable fluid 5 is stimulated to harden, for example, by means of a UV lamp. For example, the UV lamp can be attached to the arm of the machine.

[0080] It has proven advantageous if the string core is tensioned to a predefined degree during the application of the curable fluid 5, and in particular during the winding process. Such pretensioning has proven particularly advantageous during the curing process. Curing therefore occurs with a string core 2 that exhibits a certain stretch in its longitudinal direction. This results in the cured, curable fluid 5 being less likely to form gaps or cracks on the musical instrument. This has proven advantageous for generating harmonic overtones.

[0081] Preferably, the application of the curable fluid 5 and the thermal treatment or electromagnetic irradiation can be carried out in a single work step. In this case, the application of the curable fluid 5 and the winding of the first winding element 3 around the supporting string core 2 and the thermal treatment or electromagnetic irradiation can preferably be carried out in a single work step. This allows the production of the musical string 1 to be carried out in a particularly efficient manner. It can preferably be provided that the first winding element 3 is formed from a transparent material 6. This is shown as an example in Fig. 3. The transparent material 6 is a material that transmits electromagnetic waves. As a result, the curable fluid 5 can be cured particularly easily using a UV lamp. This further results in freedom in the selection of the curable fluid 5 and in the application of the curable fluid 5.This allows even areas of the musical string 1 that would be concealed by the first winding element 3 during irradiation of the wound musical string 1 to be cured particularly easily after the application of the winding layer. Irradiation of the musical string 1 with UV light can preferably be carried out using a conventional UV lamp.

[0082] Preferably, it can also be provided that the second winding element 8 or a further winding element is formed from the transparent material 6.

[0083] It can preferably be provided that the first winding element 3 has a substantially angular cross-section. Preferably, the first winding element 3 with the substantially angular cross-section can have rounded corners. This is shown by way of example in Fig. 2. It can preferably be provided that the first winding element 3 has a cross-section with at least two, preferably three or four, straight, in particular substantially parallel sides in pairs, and rounded connecting regions between the sides. In this case, the first winding element 3 can preferably have a cross-section with a width 7 and a height 9. The height 9 is arranged perpendicular to the string core 2 and is to be measured. This makes it possible to achieve a reflection of an irradiated electromagnetic wave on the sides of the first winding element 3, which additionally assists the curing of the fluid 5.This results in particular in a synergistic effect in the formation of the first winding element 3 from a transparent material 6.

[0084] It can preferably be provided that the first winding element 3 has a substantially round cross-section.

[0085] It can preferably be provided that the first winding element 3 is wound around the supporting string core 2 in such a way that distances are formed between adjacent turns of the first winding element 3 which are smaller than the width 7 of the first winding element 3. The width 7 can preferably be the minimum width. The minimum width means in particular the width which results when the width of the first winding element 3 is measured at different points along the first winding element 3 and the average is calculated from these measured values. This allows the curable fluid 5 to be arranged particularly well between the first winding element 3 and the supporting string core 2. This allows, for example, a low-viscosity curable fluid 5 or a curable fluid 5 with a low viscosity to be held well between the turns until it has been cured to the desired hardness.Furthermore, Fluid 5 can be cured particularly easily using a UV lamp.

[0086] It can preferably be provided that the hardenable fluid 5 is additionally arranged between adjacent windings of the first winding element 3. In the musical string 1, the hardenable fluid 5 can be arranged not only between the first winding element 3 and the supporting string core 2, but also between adjacent windings of the first winding element 3. This results in additional advantages, in particular, in adjusting the damping of the vibration behavior of the musical string 1.

[0087] It can preferably be provided that the musical string 1 comprises the second winding element 8, which second winding element 8 is wound in the form of a helical line around the supporting string core 2, that the second winding element 8 is arranged between the first winding element 3 and the supporting string core 2, and that the curable fluid 5 is additionally arranged between adjacent turns of the second winding element 8. As a result, in the musical string 1, the curable fluid 5 can be arranged not only between the first winding element 3 and the second winding element 8 and between the second winding element 8 and the supporting string core 2, as shown by way of example in Fig. 5, but the curable fluid 5 can also be arranged between the adjacent turns of the second winding element 8. As a result, additional advantages can be achieved when adjusting the damping of the vibration behavior of the musical string 1.Preferably, if the musical string 1 comprises further winding elements in addition to the first winding element 3 and the second winding element 8, the curable fluid 5 can additionally be arranged between adjacent turns of the further winding elements.

[0088] It can preferably be provided that the hardenable fluid 5 is applied to the supporting string core 2. This allows the supporting string core 2 to be particularly well protected from environmental conditions, such as humidity, whereby, on the one hand, the string core 2 can be protected from corrosion and the absorption of humidity, and, on the other hand, the sound character of the musical string 1 can be protected from changes.

[0089] Preferably, the curable fluid 5 may comprise or be formed from a synthetic resin, in particular a polyester resin or a polyurethane resin.

[0090] Preferably, the curable fluid 5 may comprise acrylic acid or itaconic acid as UV-curing component.

[0091] The curable fluid 5 can preferably comprise a solvent. The solvent can preferably influence the curing of the curable fluid 5. This allows the curing of the curable fluid 5 to be better controlled. By adding the solvent, for example, a slow post-curing of the curable fluid 5 can be achieved, whereby the tonal character of the musical string 1, in particular the brilliance of the musical string 1, can be improved over time. Since it is known that a conventional musical string has a "duffier" tonal character after extended periods of play, a consistent tonal character can be achieved with the musical string 1 according to the invention even after extended periods of play by adding the solvent and the resulting post-curing of the curable fluid 5.

[0092] It can also preferably be provided that only partial crosslinking takes place, which is limited to the outer sections or interfaces. This makes it possible to achieve a solid outer surface or area, which guarantees sufficiently high stability, while a viscous fluid exists inside, which has a predeterminable internal damping. The thermal treatment of the curable fluid 5 can preferably be carried out using a heat source.

[0093] The thermal treatment of the curable fluid 5 can preferably be carried out in an oven. After the first winding element 3 has been wound around the supporting string core 2, the musical string 1 can preferably be placed in an oven and thermally treated, in particular subjected to a temperature treatment, in the oven.

[0094] Preferably, the electromagnetic irradiation of the curable fluid 5 can be carried out with a UV lamp, in particular a UV-LED lamp.

[0095] The manufacture of the musical string 1 according to the invention will be explained in more detail below using an example.

[0096] Preferably, based on the specifications of tone, scale length, and string tension, a material mix, in particular a mix of different materials, is selected for the string core 2, the first winding element 3, and possibly further winding elements of the musical string 1. The string core 2 of the musical string 1 is preferably clamped in a machine for applying the winding layer(s) in such a way that the string core 2 can be set in rotation. The machine preferably comprises an arm that is movable from one end of the clamped string core 2 to the other end of the clamped string core 2. A spray gun for applying the curable fluid 5 and a UV lamp for curing the fluid 5 are preferably arranged on the arm of the machine. The spray gun is preferably arranged in front of the UV lamp, viewed in the winding direction.The arm of the machine preferably moves from one end of the clamped string core 2 to apply the first winding element 3, applies the curable fluid 5 before applying the first winding element 3 and cures the fluid 5 after application, in particular at the first string core location 4 with the UV lamp.

[0097] The following are principles for understanding and interpreting the disclosure in question. Features are typically introduced with the indefinite article "a, an, one, one." Therefore, unless the context indicates otherwise, "a, an, one, one" is not to be understood as a number.

[0098] For ranges of values, the endpoints are included unless the context indicates otherwise.
