Method for producing a musical string

The invention relates to a method for producing a musical string according to the

Preamble of patent claim 1.

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 their tuning stability, as moisture absorption can cause the tension of the strings to change.

is changed.

Furthermore, it is well known that for a musical string, especially for string instruments, the specifications of tone, scale length, and string tension are of particular importance. Today's newer musical strings have a string core and one or more windings, so-called winding layers. The string core is loaded when the musical string is tensioned and carries or absorbs the tuning weight, whereas the winding

Mass of the musical string increased.

The disadvantage is that the material mix or mix of different materials used in musical strings is influenced by the environmental conditions,

which causes the properties of the musical string to change over time.

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 high tuning stability. According to the invention, this is achieved by the features of patent claim 1.

This has the advantage of creating a musical string with consistent properties over a longer period of time. This allows the damping of the vibration behavior of the musical string to be adjusted using the fluid. This allows, for example, the sound character of the

musical string, such as the brilliance and warmth, as well as the variety of timbres, how rich

and complex or pure, of the musical string. This can reduce corrosion on the musical string as well as the absorption of moisture by the musical string. This allows materials to be used in the production of the musical string which, without protection from environmental conditions, such as heat or humidity, exhibit strong 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 closely approximates the sound character of a natural gut string while still retaining

is as insensitive as possible to environmental conditions. The invention further relates to a musical string according to claim 11.

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

It is resistant to moisture absorption and has high tuning stability. According to the invention, this is achieved by the features of patent claim 11.

The advantages of the musical string correspond to the advantages of the above-mentioned

Method. The subclaims relate to further advantageous embodiments of the invention.

The invention will be described with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example.

described in more detail. It shows:

Figs. 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 between the first winding element 3 and the supporting string core 2 a hardenable fluid 5 is arranged, which hardenable fluid

5 is predeterminably treated thermally or electromagnetically.

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 at least

thermally treated or electromagnetically irradiated for a predefined period of time.

This results in the advantage that a musical string 1 can be created which has consistent properties over a longer period of time. The damping of the vibration behavior of the musical string 1 can thus be adjusted by means of 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 maintained. 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, would be subject to strong fluctuations in their

properties. In summary, this makes it possible to make a musical string

1 for a specific musical instrument and musician from a material mix, which comes close to the sound character of a natural gut string

and is as insensitive as possible to the environmental conditions.

The preferred embodiments shown in Figs. 1 to 5 are shown in a simplified representation. The proportions do not necessarily correspond to the intended real proportions. For a better understanding,

individual parts may be shown in a greatly enlarged view.

When looking at 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 even more individually adapted to the musician and a specific musical instrument, as more freedom in the choice of materials is achieved during the production of the musical string 1, while still retaining the advantages of the hardenable fluid

5 can be formed on the musical string 1.

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.

Number of coatings arranged one above the other.

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.

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.

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 two flat strips 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.

Preferably, during winding, a respective winding tangent of the round wires

irradiated to achieve a predetermined hardness of the curable fluid 5.

According to a first preferred thermal treatment, it is provided that the hardenable fluid 5 is cooled to a predetermined degree before being wound or wrapped with the first winding element 3, in particular to a temperature of 4 to 18 degrees. This thickens the hardenable fluid 5. After the winding process, the intermediate product of the musical string 1 to be produced is heated, whereby the viscosity of the hardenable fluid 5 is reduced to a predetermined degree and it becomes

a targeted distribution of the curable fluid 5 in the spaces between

10

the string core 2 and the first winding element 3. In a subsequent

In this process step, the curable fluid 5 is cured or solidified.

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 uniform 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.

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 hardening.

The curable fluid 5 may comprise a solvent. Alternatively,

the curable fluid 5 must be solvent-free.

According to a fourth preferred thermal treatment, the curable fluid 5 necessarily comprises a solvent. A predetermined heating can be used to specifically cause the solvent to escape. This

leads to hardening of the curable fluid 5.

Furthermore, according to a fifth preferred embodiment, the curable fluid 5 is designed as a highly viscous adhesive which, before

The winding process is heated to reduce the viscosity.

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, a

another of the at least two components may be a synthetic resin.

Preferably, the thermal treatment of the first string core location 4 can also be a

11

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 an example of a string core location 2 of the musical string 1, wherein the reference numeral 4 indicates a cross-section of the musical string 1. As a result, the curable fluid 5 can advantageously be applied before winding the first winding element 3 around the supporting string core 2, but also in a

Work step in the winding, can be applied particularly easily.

Hardness is defined as the resistance of a material to the penetration of a harder body. Common hardness measurements, especially for polymers, are the Shore hardness measurement method or IRHD (International

Rubber Hardness Degree).

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 a Shore A hardness of at least 10, particularly preferably of at least

20, especially 40.

required to harden fluid 5.

The electromagnetic radiation preferably has a wavelength of at least 100 nm, particularly preferably of at least 400 nm, in particular of at least 780 nm.

Preferably, the electromagnetic radiation has a wavelength of maximum 1 mm, particularly preferably of maximum 780 nm, in particular of maximum 400 nm,

12

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, whereby the fluid 5 can be cured particularly easily. This allows the fluid 5 to be used in the production of the musical string 1.

can be hardened particularly easily.

Preferably, the electromagnetic radiation is UV radiation. UV radiation is in particular electromagnetic radiation between at least 100 nm and

maximum wavelength of 400 nm.

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 results in the advantage that a curable fluid 5 can be used, in which a chemical reaction to harden the fluid 5 is triggered by the UV light flash. This makes it particularly easy to harden the fluid 5 even in places that are hidden from the UV light, for example, by the first winding element 3. Preferably,

The curable fluid 5 may be an epoxy resin.

Preferably, the electromagnetic radiation is infrared radiation. Infrared radiation is defined as electromagnetic radiation between at least

780 nm to a maximum of 1 mm wavelength.

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 in such a way 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.

is applied.

13

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 one work step. This can further improve the workflow in the production of the musical string 1. For example, the supporting string core 2 can be clamped by its two ends in a machine, 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 before winding, for example by means of a brush or by spraying, for example by means of the spray nozzle, the curable fluid 5 is applied or applied to the supporting string core 2. For example, the brush or the

Spray gun must be attached to the arm of the machine.

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 one work step. This can further improve the workflow in the production of 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, for example, by means of a UV lamp or an infrared lamp, the curable fluid 5 is stimulated to harden. For example, the UV lamp or the infrared lamp can

be attached to the arm of the machine.

It has proven advantageous if the string core is tensioned to a predetermined extent during the application of the curable fluid 5 and, in particular, during the winding process. Such pre-tensioning has proven particularly advantageous during the curing process. Therefore, curing occurs with a string core 2 that exhibits a certain stretch in its longitudinal direction. This can ensure that the cured, curable fluid 5 has a reduced tendency to form gaps or cracks on the musical instrument.

cracks. This has proven to be advantageous for creating harmonious

Overtones proved.

Preferably, the application of the curable fluid 5 and the thermal treatment or electromagnetic irradiation can be carried out in one step. Preferably, 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 be carried out in one step. This allows the production of the musical string 1

in a particularly efficient manner.

It can preferably be provided that the first winding element 3 is made of a transparent material 6. This is shown by way of example in Fig. 3. The transparent material 6 is a material that allows electromagnetic waves to pass through. This allows the curable fluid 5 to be cured particularly easily using a UV lamp or an infrared lamp. This also results in freedom in the choice of the curable fluid 5 and in the application of the curable fluid 5. This also allows areas of the musical string 1 that would be covered by the first winding element 3 when the wound musical string 1 is irradiated to be cured particularly easily after the winding layer has been applied. The irradiation of the musical string 1 using UV

Light is preferably carried out using a conventional UV lamp.

Preferably, it can also be provided that the second winding element 8 or a

another winding element is made of the transparent material 6.

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 essentially parallel in pairs, sides 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 normal to

String core 2 and to measure. This allows a reflection of a

15

radiated electromagnetic wave on the sides of the first winding element 3, which additionally supports the hardening of the fluid 5. This results in a synergistic effect in the formation of the

first winding element 3 made of a transparent material 6.

It can preferably be provided that the first winding element 3 has a

has a substantially round cross-section.

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. Preferably, the width 7 can be the minimum width. The minimum width refers in particular to 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 value 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, the fluid 5 can thereby be particularly

can be easily cured using a UV lamp.

It can preferably be provided that the hardenable fluid 5 is additionally arranged between adjacent windings of the first winding element 3. In the case of 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 the hardenable fluid 5 can also be arranged between adjacent windings of the first winding element 3. This results in particular in additional advantages in the

Adjustment of the damping of the vibration behavior of the musical string 1.

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 between

the first winding element 3 and the supporting string core 2 and

that the hardenable fluid 5 is additionally arranged between adjacent windings of the second winding element 8. As a result, in the musical string 1, the hardenable fluid 5 can be arranged not only between the first winding element 3 and the second winding element 8, as well as between the second winding element 8 and the supporting string core 2, as shown by way of example in Fig. 5, but the hardenable fluid 5 can also be arranged between the adjacent windings of the second winding element 8. This allows additional advantages to be achieved in 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 hardenable fluid 5 can additionally be arranged between adjacent windings of the further winding elements

be arranged.

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.

Preferably, the curable fluid 5 may be a synthetic resin, in particular a polyester resin

or a polyurethane resin, or be formed from it.

Preferably, the curable fluid 5 may contain acrylic acid or itaconic acid as UV-curing

component.

Preferably, the curable fluid 5 may comprise a solvent. Preferably, the solvent may influence the curing of the curable fluid 5. This allows for better control of the curing of the curable fluid 5. For example, by adding the solvent, a slow post-curing of the curable fluid 5 may be achieved, thereby improving the sound character of the musical string 1, in particular the brilliance of the musical string 1, over time.

Since it is known that a conventional musical string can become

consistent sound character can be maintained.

It can also be preferred that only partial cross-linking takes place, which is limited to the outer sections or interfaces. This allows a solid outer surface to be achieved, which guarantees sufficiently high stability, while a viscous

Fluid which has a predeterminable internal damping.

Preferably, the thermal treatment of the curable fluid 5 can be carried out with a heat source, in particular an infrared lamp or a local heat source,

be performed.

Preferably, the thermal treatment of the curable fluid 5 can 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 introduced into an oven and thermally treated in the oven, in particular

subjected to temperature treatment.

Preferably, the electromagnetic irradiation of the curable fluid 5 with

a UV lamp, especially a UV-LED lamp.

In the following, the production of the musical string 1 according to the invention will be described using a

Example can be clearly explained.

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) such that the string core 2 can be set in rotation. The machine preferably comprises an arm which is movable from one end of the clamped string core 2 to the other end of the clamped string core 2. On the arm
