Description

[0001] The invention relates to a machine for manufacturing a musical string according to the preamble of 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 into which the core is held, rotating it around its longitudinal axis for the winding process. The winding element is taken from a spool and, under tension, moves along the rotating core. This tension inevitably causes the core to shift or bend during the winding process.

[0003] The object of the invention is to provide a machine for the production of a musical string of the type mentioned above, with which the sound of the musical string can be specifically influenced and / or adjusted during the production process.

[0004] According to the invention, this is achieved by the features of claim 1.

[0005] This allows the sound of the musical string to be predictably influenced during its manufacture. This opens up expanded possibilities for adjusting or predefining the sound and handling of a musical string during or as a result of its production, regardless of the materials and dimensions used.

[0006] This allows the bending stiffness of the music string to be predictably influenced. This allows the overtone behavior of the music string to be predictably adjusted.

[0007] This allows the sound and properties of the musical string when played by the musician to be specifically influenced and adjusted through the manufacturing process, without having to change the internal structure of the musical string.

[0008] By selectively influencing the deformation of the string core during winding with at least one initial winding element, the spinning angle of the respective first winding layer can be specifically controlled. Without altering the design or dimensions of the winding point, the spinning angle that the winding element assumes at the winding point relative to the string core can be adjusted by varying the free length of the string core, which can deform or bend laterally due to the tension. This allows the bending stiffness of the musical string and thus its overtone behavior to be influenced. Consequently, the damping of the musical string can be predictably controlled.

[0009] This allows the mass of the relevant winding layer, and consequently of the musical string, to be predictably influenced. This allows the fundamental frequency of a musical string to be predictably adjusted.

[0010] This causes the outer surfaces of the winding layers to be deformed in a predictable way.

[0011] Since the free length of the string core, which twists due to the tension of the first winding element during the winding process, is directly adjusted, the torsional stiffness is also influenced. This allows the torsional rigidity and consequently the asymmetrical torsional vibrations of the musical string to be specifically influenced and predefined.

[0012] The dependent claims relate to further advantageous embodiments of the invention.

[0013] 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.

[0014] The Fig. 1 and Fig. Figure 2 shows a machine 1 for manufacturing a musical string 2 with a predetermined musical string length 3, 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 have a common clamping device pivot axis 6, wherein the first clamping device 4 and the second clamping device 5 are designed for clamping a string core 7 of the musical string 2, wherein the first clamping device 4 and / or the second clamping device 5 is displaceable for predetermined clamping of the string core 7, wherein the machine 1 has a machine bed 8 with at least one straight guide track 9, which guide track 9 is arranged parallel to the clamping device rotary axis 6, wherein a slide 10 is arranged longitudinally displaceable on the guide track 9, wherein a discharge device 11 with a discharge point 12 for the predetermined discharge of at least one first winding element 13 during a winding process is arranged on the slide 10, wherein - for the predetermined guidance of the string core 7 during the winding process - a first support part 14 is arranged in a first position 15 in relation to the unwinding device 11, and wherein a first string contact point 16 of the first support part 14 has a predetermined first distance 17 to the unwinding point 12 and forms a first plane 18, preferably horizontal, with the clamping device rotation axis 6, and / or that the string contact point 16 is arranged substantially in the clamping device rotation axis 6.

[0015] This allows the sound of the music string 2 to be predictably influenced during its manufacture. This provides expanded possibilities for adjusting or specifying the sound and handling of a music string 2 during its production, independent of the materials and dimensions used.

[0016] This allows the sound and properties exhibited by the musician when playing the music string 2 to be specifically influenced and adjusted through the manufacturing process, without having to change the internal structure of the music string 2.

[0017] By selectively influencing the deformation of the string core 7 during winding with at least one first winding element 13, the spinning angle of the respective first winding layer can be specifically controlled. Without altering the construction or the dimensions of the unwinding point, the spinning angle assumed by the first winding element 13 at the winding point 29 relative to the string core 7 can be adjusted during the winding process by varying the free length of the string core 7, which can deform or bend laterally due to the tensile force. This allows the bending stiffness of the music string 2 and thus its overtone behavior to be influenced. The damping of the music string 2 can therefore be predictably controlled.

[0018] This allows the mass of the relevant winding layer, and consequently of the music string 2, to be predictably influenced. This allows the fundamental frequency of a music string 2 to be predictably adjusted.

[0019] This causes the outer surfaces of the winding layers to be deformed in a predictable way.

[0020] Since the free length of the string core 7, which twists during the winding process due to the tensile force 36 of the first winding element 13, is directly adjusted, the torsional stiffness is also influenced. This allows the torsional strength and consequently the asymmetrical torsional vibrations of the music string 2 to be specifically influenced and predefined.

[0021] The Fig. Figures 1 to 32 show schematic representations of a physical machine 1 for manufacturing a musical string 2, preferred positionings of different parts of the machine 1, and preferred embodiments of first and further support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 according to the invention. The proportions and the exact proportions need not correspond to the intended actual proportions. For better understanding, individual parts may be shown in a greatly enlarged view or with significantly exaggerated proportions.

[0022] The machine 1 in question is designed and configured for the production of musical strings 2. Each musical string 2 is intended for use on a specific type of musical instrument. The machine 1 is particularly designed for the production of musical strings 2 for guitars or stringed instruments. Preferably, the machine 1 is not designed for the production of musical strings 2 for instruments that have a separate string for each note and where the musical string 2 is not plucked by the musician but rather pressed against a fret with their finger to produce different pitches. These include, in particular, the piano, the harpsichord, the zither, the harp, and similar instruments. Such musical strings 2 differ significantly in design from musical strings 2 for guitars or stringed 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 1 used for their production also differ.

[0023] Machine 1 has a machine bed 8. In its basic design, machine 1 resembles a lathe, but exhibits some significant differences. In addition to the machine bed 8, machine 1 has a straight guideway 9 on which a carriage 10 is longitudinally displaceable. Parallel to the guideway 9, machine 1 preferably has at least one clamping guideway 32.

[0024] Machine 1 has two rotatable clamping devices 4 and 5, which are arranged opposite each other in or on the 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.

[0025] The first clamping device 4 and the second clamping device 5 are designed and configured for 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 simple hooks.

[0026] 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 preferably has 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.

[0027] The 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. The two clamping devices 4, 5 are driven in such a way 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, or an intermediate product in the manufacture of the musical string 2, is not twisted or warped during the rotation.

[0028] In the manufacture of the musical string 2, the rotating string core 7 is helically wound or encased with at least one first winding element 13. To allow for the controlled dispensing of the first winding element 13 during the winding process, the 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 the manufacturing process. Preferably, the first winding element 13 is guided around a roller 37 before being wound onto the string core 7.

[0029] The unwinding device 11 has an unwinding point 12 at which the first winding element 13 rests and is pulled past for predetermined or controlled dispensing. The unwinding point 12 is the last point at which the first winding element 13—as it approaches the string core 7—contacts the unwinding device 11. Preferably, the unwinding device 11 has a rotatably mounted roller 37, which guides or spatially positions the first winding element 13 and is rotated by it. The unwinding point 12 is then the point at which the unwinding first winding element 13 leaves this wheel or roller 37. Fig. 1 and Fig. 2 shows an example of such a role 37. In Fig. Figure 12 shows a pipe-like drainage device 11.

[0030] 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 preferably occurs near the first tensioning device 4. The first winding element 13, now connected to the string core 7, is then tensioned with a predetermined tensile force 36, and the string core 7 is set into rotation. This rotation moves the first winding element 13 away from its source. In particular, it unwinds from the spool 34. The predetermined tensile force can be achieved and / or adjusted 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, or must be unwound due to the resistance. The higher the resistance, the higher the tensile force. Because the first winding element 13 now pulls laterally on the string core 7, the string core 7 is deflected or bent.This essentially corresponds to the behavior of a beam on two supports, on which a shear force acts.

[0031] By combining the rotation of the string core 7 and the movement of the unwinding device 11 essentially parallel to the clamping device's axis of rotation 6, the string core 7 is wound helically or helically by the first winding element 13. The contact point where the first winding element 13 touches the string core 7, and consequently the point where the tensile force 36 acts on the string core 7, is referred to as the winding point 29.

[0032] The machine 1 is designed to have at least one first support element 14, which is connected to the slide 10. This first support element 14 guides the string core 7 during the winding process in a predefinable manner or to a predefinable extent. It is arranged in a first position 15 relative to the unwinding device 11. The first position 15 refers to the unwinding device 11 and not to a stationary part of the machine 1. Therefore, if the unwinding device 11 moves, the first support element 14 moves with it or is carried along with it.

[0033] The first support element 14 can be fixedly connected to the discharge device 11. The first position 15 is then constant. According to a preferred embodiment of the invention, the first support element 14 is movably connected to the discharge device 11 in a predefinable manner. This allows the first position 15 to be modified or adapted to different requirements, for example, for the production of different musical strings 2. This allows the machine 1 to be brought into an advantageous first position 15 for the production of a first type of musical string, for example, a violin G string with a predefined structure, and in particular to be locked in this position, and for the production of a second type of musical string, for example, a cello G string with a predefined structure, to be brought into an advantageous second position and in particular to be locked in this position.This allows one machine to advantageously produce one different type of musical string with a different structure.

[0034] The adjustable positions can be achieved, for example, by a predefinable swiveling or tilting of a - as in the Fig. 1 and Fig. The fastening device 39, which connects the first support part 14 to the drain device 11, is shown schematically in Figure 2. However, the fastening device 39 can also be designed differently, for example with two bearing rails arranged at right angles to each other.

[0035] As stated above, it is preferably provided that the first support element 14 can be fixed in the different first positions 15 such that the set first position 15 is maintained during the manufacturing process. In a further preferred embodiment, the fastening device 39 can be designed, and in particular connected to the discharge device 11, such that the first position 15 can be continuously adjusted during the string manufacturing process on the machine 1, so that the first normal distance 19, or, in the case of several support elements 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48, the respective normal distances, is not kept constant, but follows a predefinable profile.

[0036] Fig. Figure 15 shows a further adjustable or adjustable and preferably controlled-regulateable mounting device 39. In the present embodiment, this device has thirteen support elements 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48, each of which is mounted on an elongated support element of the mounting device 39 by means of an actuator 38. The actuators 38 are, in particular, electrically and / or pneumatically operated mechanical actuating units. The electrically operated actuating units are, in particular, comparable to so-called servos from the field of model aircraft. Preferred pneumatically operated actuating units are, for example, pneumatic guide cylinders, pneumatic piston cylinders, and / or servo-pneumatic positioning systems. This allows the distance of the support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or support counterparts 58, 62 to the clamping device rotation axis 6 to be set and predefinable.Furthermore, it is preferably provided that the distances 83, 84 between the support elements 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or support elements 58, 62 can be changed. Preferably, the fastening device 39 has correspondingly designed devices.

[0037] According to a preferred embodiment of an actuator 38, 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 support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or the opposing support element 58, 62 is moved within a predefinable range around a target point. Subsequently, a so-called fine adjustment is performed using the electric actuating unit. The support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or the opposing support element 58, 62 is thereby moved very precisely to the desired position.

[0038] In a preferred method for manufacturing a musical string 2 using an adjustable clamping device 39, the respective normal distance of the different support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 to the clamping element's axis of rotation 6 is continuously changed. In particular, the support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48, which are not yet positioned relative to the string core 7 at the start of the string manufacturing process, are spaced from the drive and / or bearing parts of the first rotatable clamping device 4 at such a distance that movement or longitudinal displacement of the discharge device 11 in the direction of the second rotatable clamping device 5 is supported or not hindered. Fig. Figure 2 shows a machine in which the straight guideways 9 run laterally alongside the housing that carries the rotatable clamping device 4. The housing in question is designed to be correspondingly narrow in order to provide the necessary space for the straight guideways 9 and the longitudinally displaceable slide 10 arranged on them.

[0039] In a further embodiment of an adjustable fastening device 39 with at least two support parts 14, 20, the distance between the adjacent support parts 14, 20 can be changed and adjusted parallel to the pivot axis 6 of the clamping device. This allows the musical string 2 to be manufactured even more precisely according to its requirements.

[0040] In a further development of the invention, it can be provided that a fastening device 39 is designed in such a way that both the distance between at least two adjacent support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and the respective normal distance to the clamping element rotation axis 6 of the two support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 can be predetermined.

[0041] The first support element 14 can have different designs and shapes, but it always has at least one first string contact point 16, which is intended to be in direct physical contact with the string core 7 or the music string 2. This first string contact point 16 has a predefinable first distance 17 to the release point 12 of the release device 11.

[0042] In the Fig. 2 and Fig. The first distance 17 is entered at 12. As can be seen, the first distance 17 is the shortest distance between the drain point 12 and the first string contact point 16. In Fig. Figure 2 shows a coordinate system that corresponds to the coordinate system commonly used for lathes. The Z-axis is parallel to the clamping device's axis of rotation 6. The X-axis is perpendicular to the Z-axis. The X- and Z-axes are preferably arranged in a first plane 18 or parallel to it. The first plane 18 is formed by the first string contact point 16 and the clamping device's axis of rotation 6. This first plane 18 is preferably a horizontal plane, but can also be formed at a predefinable angle to a horizontal. The first plane 18 is only defined in Fig. 1 and Fig. 8 shown. Fig. 8 is the spinning point; 29 is outside the clamping device rotation axis 6. In Fig. 1 is the first level 18 projected.

[0043] As an alternative to positioning the first string contact point 16 in the first plane 18, it is preferably possible that the string contact point 16 is arranged in the clamping device's axis of rotation 6. This is the case, for example, with the first support part 14 in the embodiments according to the Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 9 the case. In the embodiments according to Fig. 8 is the third support element arranged in the clamping device's axis of rotation 6. The axis of the string core 7 remains in the clamping device's axis of rotation 6 over a large area.

[0044] The first distance 17 is the resultant of a first X-distance and a first Z-distance, and can be determined from these using the Pythagorean theorem.

[0045] Preferably, the first spacing 17 is between 0.1% and 25% of the length of the musical string 3 and / or between 10 mm and 250 mm, particularly between 75 mm and 200 mm. These ranges or spacings have proven to be easy to implement and effective in the manufacture of a musical string 2. Within these ranges or spacings, a significant influence can also be exerted on the sound of a musical string 2 manufactured in this way.

[0046] The Fig. 3 and Fig. Figure 4 shows preferred positions - only - of a first support part 14.

[0047] In the first preferred positioning of the first support part 14 according to Fig. 3 This is arranged between the discharge point 12 and the first clamping device 4. In Fig. Figure 2 shows the first Z-distance 30. The first support part 14 is further arranged such that the first string contact point 16 lies in the clamping device rotation axis 6.

[0048] In the second preferred positioning of the first support part 14 according to Fig. 4 is arranged between the discharge point 12 and the second clamping device 5. The first support part 14 is further arranged such that the first string contact point 16 lies in the clamping device's axis of rotation 6.

[0049] Although both embodiments according to the Fig. 3 and Fig. 4. If the first support element 14 is arranged in the clamping device's axis of rotation 6, it can also be positioned such that a first perpendicular distance 19 exists between the first support element 14 and the clamping device's axis of rotation 6. This first perpendicular distance 19 is at least 1 mm, in particular 2.5 mm, preferably 10 mm. This allows the angle between the string core 7 and the first winding element 13 to be changed without altering the tensile force 36.

[0050] According to a preferred embodiment of the present invention, the machine 1 has a second support part 20 for predefinable guidance of the string core 7 during the winding process. This second support part 20 is arranged in a second position 21 relative to the unwinding device 11. A second string contact point 22 of the second support part 20 has a predefinable second distance 23 to the unwinding point 12 and a predefinable third distance 24 to the first string contact point 16. This allows the formation of the first winding layer and subsequent winding layers to be further influenced.

[0051] The preferred dimensions of the second spacing 23 correspond to the preferred dimensions of the first spacing 17 and are between 0.1% and 25% of the length of the musical string 3 and / or between 10 mm and 250 mm, in particular between 75 mm and 200 mm. Preferably, the second spacing 23 is different from the first spacing 17. In particular, the second spacing 23 is larger than the first spacing 17.

[0052] The Fig. 5 and Fig. Figure 6 shows preferred positionings of a first support part 14 and a second support part 20. Fig. 12 shows this, in Fig. 6 marked details A.

[0053] By using at least two support elements 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or opposing support elements 58, 62, a walking process of the string core 7 or the music string 2 can be achieved. This allows the winding angle of the first winding element to be predictably influenced. The selected spacing allows the bending stiffness of the string core 7 to be predictably influenced. The precise position also affects the friction during the winding process. Such a walking process can also take place after all intended winding layers have been arranged on the string core 7.

[0054] In the first preferred positioning of two support parts 14, 20 according to Fig. In the preferred embodiment, the first support element 14 is arranged between the discharge point 12 and the first clamping device 4. The second support element 20 is also arranged between the discharge point 12 and the first clamping device 4. The first and second support elements 14 and 20 are each positioned in the clamping device's axis of rotation 6. Fig. 5 are the first position 15 and the second position 21 on the same side of the clamping device rotation axis 6, preferably in the first plane 18.

[0055] In the second preferred positioning of two support parts 14, 20 according to Fig. In the first support element 14, the first support element 14 is also arranged between the discharge point 12 and the first clamping device 4, and the second support element 20 is also arranged between the discharge point 12 and the first clamping device 4. The first support element 14 is furthermore arranged in the pivot axis 6 of the clamping device. In contrast to the embodiment according to Fig. 5 The second string contact point 22 is spaced apart from the clamping device rotation axis 6. There is a second normal distance 25 between these, which is at least 1 mm, in particular 2.5 mm, preferably 10 mm. In the preferred embodiment according to Fig. 6 the first position 15 and the second position 21 are arranged on different sides of the clamping device rotation axis 6, preferably in the first plane 18.

[0056] Fig. Figure 12 shows detail A according to Fig. 6. In this detail A, the first distance 17 and the second distance 23 are shown. Furthermore, the third distance 24 between the first string contact point 16 and the second string contact point 22, as well as the second normal distance 25, are shown. The third distance 24 is preferably between 7% and 15% of the music string length 3 and / or between 5 mm and 150 mm.

[0057] Preferably, the machine 1 may have a third support part 26 for predefinable guidance of the string core 7 during the winding process, this third support part 26 being arranged in a third position 27 relative to the unwinding device 11, and a third string contact point of the third support part 26 having a predefinable fourth distance to the unwinding point 12, a predefinable fifth distance to the first string contact point 16, and a predefinable sixth distance to the second string contact point 22. This allows for further targeted control of the deformations of the string core 7 during manufacturing.

[0058] The Fig. 7 and Fig. Figure 8 shows preferred positionings of a first support part 14, a second support part 20 and a third support part 26.

[0059] In the first preferred positioning of three support parts 14, 20, 26 according to Fig. The first support element 14 is arranged between the discharge point 12 and the first clamping device 4. The second and third support elements 20, 26 are arranged between the discharge point 12 and the second clamping device 5. Therefore, there are two support elements 20, 26 on the same side of the discharge point 12. The two support elements 14, 26 facing the clamping devices 4, 5 are arranged in the clamping device axis of rotation 6. The middle support element 20 is located on a different side of the clamping device axis of rotation 6 than the discharge device 11. The second support element 20 is opposite the first support element 14.

[0060] In the second preferred positioning of three support parts 14, 20, 26 according to Fig. In Figure 8, the first support element 14 and the second support element 20 are arranged between the discharge point 12 and the first clamping device 4, with the first support element 14 being located closer to the first clamping device 4. Only the third support element 26 is located in the clamping device's axis of rotation 6. The first and second support elements 14 and 20 are positioned on opposite sides of the clamping device's axis of rotation 6. The second support element 20 is located opposite the first support element 14.

[0061] Fig. Figure 9 shows a further preferred embodiment comprising four support parts 14, 20, 26, 35. The first and fourth support parts 14, 35 are arranged in the clamping device rotation axis 6, while the second and third support parts 20, 26 are each located on a different side of the clamping device rotation axis 6 than the - not shown - release device 11.

[0062] The first distance 17 can remain constant throughout the entire winding process. In a preferred embodiment of the invention, the first distance 17 is adjusted during the winding process. In particular, it is provided that the first distance 17 is changed or shifted such that the first normal distance 19 follows a predefinable curve 31. This is exemplified in the Fig. 10 and Fig. Figure 11 shows that the curve 31 can have different shapes. Preferably, the curve 21 is a convex or concave curve with a common radius. Another preferred curve shape is—as shown in Fig. 10 and Fig. Figure 11 shows a semi-ellipse. This curve 31 can also be triangular. By adjusting the first normal distance 19 in a curved manner, the angle that the string core makes relative to the tensioning device's axis of rotation 6 can be influenced. In particular, the curve is designed such that the angle between the string core 7 and the tensioning device's axis of rotation 6 is kept essentially constant over large portions of the string core 7, or the length of the musical string 3, during the manufacturing process.

[0063] Fig. Figure 13 shows a further preferred embodiment comprising thirteen support elements 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48, which are arranged such that the string core 7 or the music string 2 essentially follow a predefinable curve. In the embodiment shown here, the support elements 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 are designed as guides which predefinably surround or at least partially encompass the string core 7 or the music string 2.

[0064] Fig. Figure 14 also shows a preferred embodiment, which has six support parts 14, 20, 26, 35, 40, 41, wherein adjacent support parts are arranged in a mirror-image fashion. This represents a further preferred possibility for the targeted and advantageous influencing of a musical string 2 solely through its manufacturing process.

[0065] The aforementioned embodiments of a machine 1 according to the invention all have at least one first support element 14. The first support element 14 and the further support elements 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48, as well as the opposing support elements 58, 62 of the preferred embodiments, can have different geometric shapes. Furthermore, they can be arranged not only in series one behind the other next to or on the clamping element's axis of rotation 6. Two or more support elements 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48, as well as opposing support elements 58, 62, can together form pairs or common arrangements at a point or position with respect to the longitudinal extent of the clamping element's axis of rotation 6.

[0066] Furthermore, the support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and support counterparts 58, 62 can be mechanically connected to the slide 10 in different ways or by different mechanical means.

[0067] The support elements 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and the opposing support elements 58, 62 can be fixedly arranged or their orientation relative to the clamping element's axis of rotation 6 remain constant at every position of the slide 10 during the manufacturing process, or they can be fixedly connected to the slide 10. Alternatively, or in a further development, they can also be connected to the slide 10 by means of an adjustable, movable, in particular rotatable, displaceable, and / or tiltable, support device 81. This allows the position of the at least one first support element 14 relative to the clamping element's axis of rotation 6 to be adjusted to different positions of the slide 10 on the guide tracks 9. This enables different positions to be used for the production of different types of musical strings 2.The position of at least one first support part 14 and / or the further support parts 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and support counterparts 58, 62 can further be lockable or predeterminable movable, wherein the machine 1 is designed accordingly.

[0068] According to a first, technically simple preferred embodiment, the first support part 14 is essentially designed as a cylinder 51. Fig. Figure 16 shows a schematic representation of such a support element 14. Besides a circular cross-section, the cylinder 51 can also have other cross-sectional shapes. In particular, an elliptical base has proven advantageous in operation. The first support element 14, which is shown in Fig. 1 and Fig. The first support element 14, which is arranged on the machine 1, has an elliptical base. The cylindrical first support element 14 can be arranged differently on the machine 1 and relative to the clamping device's axis of rotation 6. In particular, the cylinder 51 can be arranged at different angles relative to the clamping device's axis of rotation 6. Preferably, the axis of the cylinder 51 is arranged substantially parallel to a normal to the clamping device's axis of rotation 6. However, an angle between 70° and 110° relative to the clamping device's axis of rotation 6, deviating from 90°, is also possible.

[0069] In a further development of the cylindrical structure, which has a straight longitudinal profile, the support element 14 can be designed as a whole with a bent shape. This bending creates a profile that can be positioned relative to the string core 7 or the clamping device axis of rotation 6 in such a way that it forms a concave recess. This recess stabilizes the rotating string core 7. In particular, the first support element 14 is designed as a segment of a torus. This torus is preferably arranged substantially parallel to a normal to the clamping device axis of rotation 6. The concave side faces the clamping device axis of rotation 6. However, an angle between 70° and 110° to the clamping device axis of rotation 6, deviating from 90°, is also possible.

[0070] In a second preferred embodiment of a support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or support counterpart 58, 62 which in Fig. As shown schematically in Figure 17, it is provided that the support part 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 or the support counterpart 58, 62 is designed as a prism 52. Fig. Figure 17 shows a prism 52 with a rectangular base. Preferably, the base can also be pentagonal, hexagonal, heptagonal, octagonal and / or nine-sided. The basic shape can be either a symmetrical polygon or an asymmetrical polygon.

[0071] One of the outer surfaces of the prism 52 can form or encompass the first string contact point 16. Preferably, however, a side edge 53 of the prism 52 forms the first string contact point 16. The side edge 53 can be predefinably rounded. An outer surface of the prism 52 has a different effect on the string core 7 compared to a side edge 53 of the prism 52, so that even a simple twist of the prism-shaped first support part 14 can directly influence the manufacturing process and the properties of the manufactured musical string 2.

[0072] In addition to the design of the first string contact point 16, the position and angle relative to the clamping device's axis of rotation 6 also influence the effect of the first support element 14 and the further support elements 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and opposing support elements 58, 62 during the manufacturing process. Preferably, a side edge 53 of the prism 52 is arranged substantially parallel to a normal to the clamping device's axis of rotation 6. However, an angle between 70° and 110° relative to the clamping device's axis of rotation 6, deviating from 90°, is also possible.

[0073] According to a preferred embodiment, it is particularly provided that the support part 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or support counterpart 58, 62 has a first receiving notch 54, receiving groove, or receiving recess within which the first string contact point 16 is arranged or which forms it. The string contact point 16 is in particular not a single point in three-dimensional space, but a linear progression or a series of individual points which essentially follow or span a line, and which, in operation, make direct contact with the string core 7 or a winding element 13 arranged on the string core 7.

[0074] A special receiving notch 54 allows the string core 7 to be guided precisely and securely during the winding process. This reduces the likelihood of the string core 7 breaking out or "jumping" over the support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 or the opposing support element 58, 62. The first receiving notch 54 is preferably arranged substantially parallel to the axis of rotation 6 of the clamping device, but can also be arranged at an angle to it, for example at an angle of up to ± 15°.

[0075] Fig. Figure 18 shows a schematic representation of a first support element 14 according to a third preferred embodiment. The first receiving notch 54 has a substantially semicircular cross-section 55. The cross-section 55 may deviate from the semicircular shape and, for example, include straight end regions. Furthermore, the cross-section 55 can also be semi-elliptical. Preferably, the shape of the receiving notch 54 follows an exponential function. Preferably, the semicircle or the segment of a semicircle provided has a radius that is predefinably larger than the radius of the string core 7. Preferably, the radius is also larger than the radius of the combination of the string core 7 with the first winding element 13 arranged thereon. The cross-section is to be considered perpendicular to a longitudinal extension of the receiving notch 54 or to the longitudinal direction of the clamping device's axis of rotation 6.The first support element 14 is preferably arranged on the machine 1 such that the longitudinal extent of the receiving notch 54 lies parallel to the clamping device rotation axis 6. In a further preferred embodiment of the third preferred design, the cross-section 55 has a constant change in the radius of curvature.

[0076] Fig. Figure 19 shows a schematic representation of a support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or support counterpart 58, 62 according to a fourth preferred embodiment. In this embodiment, the receiving notch 54 has a substantially V-shaped cross-section 56. This provides the receiving notch 54 with two first string contact points 16, which allows the position of the string core 7 to be defined more precisely, since it does not experience any lateral vibrational deflections from a center point. The cross-section is to be considered perpendicular to a longitudinal extension of the receiving notch 54. The support part 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or support counterpart 58, 62 is preferably arranged on the machine 1 such that the longitudinal extent of the receiving notch 54 is parallel to the clamping device rotation axis 6.

[0077] In addition to the preferred forms of the individual support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or the individual support counterparts 58, 62 discussed above, which - as in the Fig. 1 to 15 shown - in different numbers and different positions, a further development of the invention provides that at least two support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 or at least one support part 14 and at least one support counterpart 58 together form a unit or a first support part device.

[0078] The Fig. 26 and Fig. Figure 27 shows a sixth preferred embodiment of a support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or support counterpart 58, 62. This embodiment, like the third preferred embodiment according to Fig. 18 a receiving notch 54, the cross-section of which essentially corresponds to a circular segment or an ellipse. The side edges or end regions of the receiving notch 54 are rounded or chamfered. Fig. Figure 27 shows the section view B - B. The rounded side edges of the receiving notch 54 are visible.

[0079] Fig. Figure 20 shows a fifth preferred embodiment of a first support part 14, which is part of a support device 57.

[0080] The first support element 14 according to the fifth preferred embodiment has a receiving groove 54 which has a convex shape in the longitudinal direction of the clamping element's axis of rotation 6. This has proven advantageous because it prevents sharp bending of the string core 7. A convex shape has different effects on the manufactured musical string 2 than a sharp-edged shape. Both variants can be used to achieve different desired properties of the musical string 2.

[0081] The support device 57, which is in Fig. As shown in Figure 20, the first support element 58 further comprises a first support element 58, which in this preferred embodiment is arranged essentially opposite the first support element 14. In this embodiment, the first support element 58 has a receiving groove 54, which has a concave profile. This ensures that the string core 7 is subjected to opposing forces and is held and guided within the support device 57 transversely to its longitudinal extent. The first support element 14 and the first support element 58 preferably have recesses whose profiles do not have the same radii, but are each specifically adapted to the string core 7.

[0082] Between the first support part 14 and the first support counterpart 58, there is a first distance 67, which is the distance between the first string contact point 16 and the first string counter-contact point 59. The first string contact point 16 is the location of the receiving notch 54, which makes initial contact with the string core 7. Similarly, the first string counter-contact point 59 is the location of the first support counterpart 58, which makes initial contact with the string core 7. In the embodiment according to Fig. 20 the first support opposite 58 therefore has two first string opposite contact points 59.

[0083] Preferably, the first distance 67 is adjustable. Preferably, the support device 57 comprises a mechanical or electromechanical arrangement or device which is at least indirectly connected to the first support part 14 and the first support counterpart 58 in order to adjust the first distance 67. The adjustability of the first distance 67 serves to apply a predetermined first compressive force to a string core 7 arranged between the first support part 14 and the first support counterpart 58 in a targeted and controllable manner.

[0084] Fig. Figure 25 also shows an arrangement consisting of a first support part 14 and a first support counterpart 58, each essentially comprising a support part 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and support counterpart 58, 62 according to Fig. 18 or Fig. 26, Fig. 27 correspond to or resemble. The first support part 14 is arranged opposite the second support part 58, so that a string core 7 can be arranged between the two and enclosed by them. The two support parts, 14 and 58, are each connected to a part of a support device 57 or a carrying device 81, respectively. This connection can – also in other embodiments – include a spring.

[0085] The first support element 14 and the first support element 58 are arranged, according to a first preferred arrangement, essentially directly opposite each other and essentially parallel to each other. The respective positions of the two elements relative to each other are predeterminable. A first angle 64 exists between the first support element 14 and the first support element 58, which is preferably between 165° and 195°, and more preferably between 175° and 185°. The first angle 64 is the angle that exists between a first connecting section 65 and a second connecting section 66. The first connecting section 65 is the straight line between the clamping element's axis of rotation 6 and the first string contact point 16. The second connecting section 66 is the straight line between the clamping element's axis of rotation 6 and the first string contact point 59. Fig. Figure 21 shows a corresponding embodiment, wherein the first support part 14 and the first support counterpart 58 are arranged at the first angle 64 to each other, which is approximately 175°.

[0086] According to a preferred embodiment of the support device 57, the first angle 64 is adjustable. This allows the machine 1 to be set up for the production of different musical strings 2. Furthermore, it is preferably provided that the first angle 64 is continuously or location-dependently changed during an ongoing production process.

[0087] In addition to the first support part 14 and the first support counterpart 58, the machine 1 preferably further comprises a second support part 20 with a second string contact point 61.

[0088] The second support element 20 is arranged, with respect to the cross-section of the string core 7, between the first support element 14 and the first support counterpart 58, whereby – in the operating position – this can be above or below the clamping device rotation axis 6. The second support element 20 has a second string contact point 61. The second support element 20 preferably has the same design or configuration as the first support element 14.

[0089] Preferably, a second angle 68 between the first support part 14 and the second support part 20, which is predefinable and preferably also adjustable, is between 30° and 105°, preferably between 60° and 95°. The second angle 68 is the angle between the first connecting section 65 and a third connecting section 69. The third connecting section 69 is the straight line between the clamping device's axis of rotation 6 and the second string contact point 61. Fig. Figure 22 shows an embodiment with a second support part 20, in which the second angle 68 is also shown.

[0090] In addition to the first support part 14, the first support counterpart 58 and the second support part 20, the machine 1 preferably further comprises a second support counterpart 62 with a second string counter contact point 63.

[0091] The second support element 62 is arranged, with respect to the cross-section of the string core 7, between the first support element 14 and the first support element 58, or opposite the second support element 20, whereby – in the operating position – this can be above or below the pivot axis 6 of the clamping device. The second support element 62 has a second string contact point 63. The second support element 62 preferably has the same design and configuration as the first support element 14.

[0092] Preferably, a third angle 70 is provided between the first support part 14 and the second support counterpart 62, which is predefinable and preferably also adjustable, and measures between 75° and 105°, preferably between 85° and 95°. The third angle 70 is the angle between the first connecting section 65 and a fourth connecting section 71. The fourth connecting section 71 is the straight line between the clamping device's axis of rotation 6 and the second string counter-contact point 63. Fig. Figure 22 shows an embodiment with a second support element 62, with the third angle 70 also shown.

[0093] Furthermore, the position of the second support element 62 relative to the second support element 20 is preferably also predetermined. A fourth angle 72 exists between these, which is preferably between 165° and 195°, and more preferably between 175° and 185°. The fourth angle 72 is the angle between the third connecting section 69 and the fourth connecting section 71. The embodiment according to Fig. Figure 22 also shows a second support element 62. Furthermore, the fourth angle 72 is also shown.

[0094] The individual support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and support counterparts 58, 62 can be arranged or positioned in very different ways and thus adapted to the different advantageous arrangements for the manufacture of a certain type of musical string 2.

[0095] As explained above regarding the first distance 67 between the first support part 14 and the first support counterpart 58, it is preferably also provided that a second distance between the second support counterpart 62 and the second support part 20 is adjustable. This allows a predefinable second compressive force to be applied to the string core 7, which is arranged or clamped between the second support part 20 and the second support counterpart 62.

[0096] The Fig. 23 and Fig. Figure 24 shows another preferred embodiment. This embodiment comprises the first support part 14, the second support part 20, and a third support part 26. The second support part 20 and the third support part 26 are arranged one behind the other, parallel to the clamping device's axis of rotation 6. In the operating position, they are preferably arranged substantially horizontally. The second support part 20 and the third support part 26 are preferably arranged at different distances from the clamping device's axis of rotation 6, since the diameter of the intermediate product of the musical string 2 being manufactured changes as soon as the first winding element 13 or a further winding element is wound around the string core 7. In the example according to Figure 24, the diameter of the intermediate product of the musical string 2 being manufactured changes as soon as the first winding element 13 or a further winding element is wound around the string core 7. Fig. 23 The distance of the third support part 26 to the clamping device rotation axis 6 corresponds essentially to the radius of the string core 7. The distance of the second support part 20 to the clamping device rotation axis 6 is the radius of the string core together with the thickness of the first winding element 13.

[0097] Between the second support part 20 and the third support part 26, in the embodiment according to Fig. 23 and Fig. 24 - the first support element 14 is arranged. The first support element 14 is arranged at a predetermined angle to the second support element 20 and the third support element 26. The angle is preferably selected such that the tensile force 36 on the first winding element 13, as well as the friction or frictional forces due to the rotational movement of the string core 7, press the string core 7 or the intermediate product against all three support elements 14, 20, 26. This ensures that the position of the spinning point 29 can be determined very precisely.

[0098] In further development, it is preferably provided that a pair consisting of the first support part 14 and the first support counterpart 58 - adjacent in the longitudinal direction of the string core - is arranged adjacent to the second support part 20 and / or the second support counterpart 62.

[0099] Fig. 18, Fig. 20 as well Fig. Figures 30 each show a preferred embodiment of a support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or support element 58, 62, or of a machine 1. The support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or support element 58, 62 preferably further comprises a receiving bore 80, which serves to receive a shaft or axle, in particular a load-bearing one. When receiving a shaft or axle, it is particularly provided that it is rotatably connected to the slide 10, preferably by means of one or two ball bearings, at least indirectly. The receiving bore 80 does not necessarily have to be produced by means of a drill. The receiving bore 80 preferably runs essentially perpendicular to the clamping device rotation axis 6.

[0100] The Fig. 18 and Fig. Figures 20 each show embodiments in which the support part 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or the opposing support part 58, 62 have a substantially prismatic basic structure. The receiving bore 80 is arranged such that, in the intended machine 1, it lies perpendicular to the clamping element's axis of rotation 6 and allows a tilting movement in the direction of, or parallel to, the clamping element's axis of rotation 6. This allows the support part 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and / or opposing support part 58, 62 to adapt to the respective position of the string core 7 or the music string 2. This prevents the occurrence of compressive forces at the corners of the support parts 14, 58, 20, 62. This positively influences the surface structure of the musical string. Due to the geometry of the base body of the in Fig. 18 and Fig. The support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 and the opposing support parts 58, 62 shown in the figure do not allow for complete rotation of the same, nor is such rotation intended.

[0101] Fig. Figure 30 shows a further preferred embodiment of a support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48. In this embodiment, the support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 has a substantially cylindrical basic shape, with the side surfaces extending concavely inwards. The support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 has an axis of rotation. The support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 is rotatably mounted, preferably on both sides. In the illustrated embodiment, a ball bearing 82 is arranged at the top and bottom, connecting the support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 to a support device 81. The support element 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 is rotatable. Due to sliding friction, the support parts 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 rotate when the slide 10 moves.This prevents sliding along the music string 2 or the string core 7. This allows for different surface properties of the first and subsequent winding elements 13. The concave shape of the support part 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 more precisely defines the position of the string core 7 and prevents the string core 7 from slipping out or jumping out of the support part 14, 20, 26, 35, 40, 41, 42, 43, 44, 45, 46, 47, 48 during the winding process.

[0102] The Fig. 31 and Fig. Figure 32 shows three cylindrical support parts 14, 26, 20, which are also rotatable and arranged in predefinable positions relative to each other. Fig. Figure 32 shows the arrangement from the perspective of position C, which is located in Fig. Figure 31 is shown. The first support element 14 and the third support element 26 are arranged in series with each other, i.e., one behind the other, and have the same axes of rotation. A space exists between the two, in which the second support element 26 is arranged, which has a different axis of rotation than the first and third support elements 14, 20. The two axes of rotation are, in particular, substantially parallel to each other. The two serial support elements 14, 20 and the single support element 26 arranged between them are positioned such that the string core 7 rests against all three support elements 14, 26, 20 and is pressed against them by its rotational movement and static friction. The distance between the two axes of rotation of the support elements 14, 26, 20 is selected such that the string core 7 is held between the support elements 14, 26, 20 during the winding process. In addition to the parallel spacing, the diameters of the support parts 14, 26, 20 must also be selected.These are preferably at least 3, in particular 5, times larger than the diameter of the string core 7.

[0103] As already mentioned Fig. As described in section 21, it may be provided in particular that the first and / or subsequent angles 64, 68, 70, 72 can be set or predefinably adjusted. The first and / or one of the subsequent support elements 14, 26, 20 are therefore preferably rotatably or tiltably arranged on the support device 57 or a carrying device 81. The respective set position is preferably mechanically lockable.

[0104] Fig. Figure 28 shows a further development in which the carrying device 81 can be pivoted, thereby allowing the support element 14 to be adjusted in height. Furthermore, this support element is connected to the carrying device 81 by a tiltable support device 57. These possibilities allow the musical string to be manufactured to be further influenced, and its properties – independent of its construction – to be further modified. Fig. Figure 29 shows a similar embodiment in which the carrying device 81 can have different lengths 85.

[0105] The following are principles for understanding and interpreting the disclosure in question.

[0106] 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.

[0107] The phrase "essentially" in conjunction with a numerical value includes a tolerance of ± 10% around the stated numerical value, unless otherwise indicated by the context.

[0108] Value ranges include the endpoints unless the context indicates otherwise.
