Description

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

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

[0003] DE 27 36 567 A1 describes a winding machine which has a guide device that is not located at the winding point, but rather precedes it during the winding process. The machine according to DE 27 36 567 A1 merely limits the deflection of the string core due to the tensile force on the winding element.

[0004] US 2001 / 039722 A1 describes a winding machine, although the winding process within the play area is not relevant. Rather, it describes the attachment of the so-called button.

[0005] US Patent 3,990,220 A describes a winding machine in which the winding process takes place within a round opening, with the winding element also being fed through a closed round opening.

[0006] The object of the invention is to provide a winding machine for a musical string of the type mentioned above, with which the sound and playability of the musical string, in particular via its length, and therefore its sound and playability when playing, especially in different positions, can be predictably influenced and / or adjusted during or through the manufacturing process.

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

[0008] This allows the sound and playability of the musical string to be predictably influenced and / or adjusted during or through the manufacturing process. This expands the possibilities for adjusting, specifying, or adapting the sound and playability of a musical string during or as a result of its production, independent of the materials used, its construction, and / or its dimensions. Therefore, it is not necessary to change the materials, construction, and / or dimensions to alter the sound and / or playability of the musical string.

[0009] The invention further relates to a method for manufacturing a musical string according to the preamble of claim 10.

[0010] The invention therefore further aims to selectively influence the sound of a musical string by means of the method of its manufacture.

[0011] According to the invention, this is achieved by the features of claim 10.

[0012] The advantages of the procedure correspond to the advantages of the aforementioned generic term.

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

[0014] The invention is described in more detail with reference to the enclosed drawings, in which only preferred embodiments are shown by way of example. These show: Fig. 1 a schematic diagram of a winding machine for the production of a musical string; Fig. 2 a floor plan of the winding machine according to Fig. 1 ; Fig. 3 a first preferred embodiment of a guide device in axonometric view; Fig. 4 the control device according to Fig. 3 in the floor plan; Fig. 5 the control device according to Fig. 3 in elevation; Fig. 6 an elevation view of a second preferred embodiment of a guide device; and Fig. 7an elevation view of a third preferred embodiment of a guide device;

[0015] The Figs. 1 and 2 show a preferred embodiment of a winding machine 1 for a musical string 2, comprising a first rotatable clamping device 4 and a second rotatable clamping device 5, wherein the first clamping device 4 and the second clamping device 5 are configured for clamping a string core 7 of the musical string 2 and for rotation about a clamping device rotation axis 6 in a direction of rotation 28, further comprising a feeding device 11 for feeding at least one first winding element 13 in a first feeding direction 15 to the string core 7 during a winding process, further comprising a guide device 16 for predefinable, section-wise guiding of the string core 7, wherein the guide device 16 together with the feeding device 11 is movable parallel to the clamping device rotation axis 6 between the first clamping device 4 and the second clamping device 5, wherein the feeding device 11 and the guide device 16 are configured and interact such that at every point in time during the winding process an actual winding point 17 is formed in the guide device 16,where the first winding element 13 begins to be wound around the string core 7, the guide device 16 having a first contact part 21 with a first contact surface 18 and a second contact part 22 with a second contact surface 19, wherein a slit-shaped feed opening 31 for the first winding element 13 exists between the first contact part 21 and the second contact part 22, wherein - viewed along the clamping device rotation axis 6 - the first angle α between the first contact surface 18 and the second contact surface 19 is between 55° and 125°, preferably between 75° and 105°, wherein the first angle α is adjustable.

[0016] This allows the sound and playability of the second musical string to be predictably influenced and / or adjusted during or through the manufacturing process. This provides expanded possibilities for adjusting, defining, or adapting the sound and playability of a second musical string during or as a result of its manufacture, independent of the materials used, its internal structure, and / or its dimensions. Therefore, it is not necessary to change the materials, internal structure, and / or dimensions to alter the sound and / or playability of the second musical string.

[0017] In known manufacturing methods on previously used winding machines, the deformation and / or deflection of the string core at the current winding point 17, which can also be referred to as the winding point, cannot be specifically controlled or adjusted. During winding, the string core 7 and the first winding element 13 are deformed. These deformations are largely elastic and, depending on the magnitude of the tension force of the string core 7 and the magnitude of the initial tensile force 15 on the first winding element 13, also plastic. This lateral deflection, in conventional manufacturing methods and known machines, depends on the tension force on the string core 7 and the initial tensile force 14 on the first winding element 13.This deformation is further influenced by the angle between the approaching first winding element 13 and the clamping device rotation axis 6, as well as by the position of the current winding point 17 between the two clamping devices 4, 5.

[0018] Using the winding machine 1, this deformation can be preset independently of the aforementioned parameters. The deformation and / or deflection of the string core 7 or the musical string 2 during the manufacturing process can be preset on the winding machine 1 according to the invention without changing the tension force on the string core 7 and / or the initial tension force 15 on the first winding element 13 and / or the angle between the tapered first winding element 13 and the clamping element axis of rotation 6. Furthermore, the deformation and / or deflection can also be preset independently of the position of the current winding point 17 between the two clamping elements 4, 5. This makes it possible to produce musical strings with a predetermined sound and playability.

[0019] This allows the bending stiffness of the finished music string 2 to be predictably influenced. This allows the overtone behavior of the vibrating music string 2 to be predictably adjusted.

[0020] This allows the lateral deflection of the string core 7 from the tensioning device's axis of rotation 6 to be very finely adjusted at the spinning point or the current winding point 17. This also essentially prevents this deflection. Preventing this deflection has a direct influence on the winding process and the vibrational characteristics of the manufactured musical string 2. This enables particularly precise winding of the first winding element 13, as the string core 7 cannot yield unpredictably to the tension 14. This has proven especially advantageous when the tension on the first winding element 13 is varied along the length of the string core 7.

[0021] In the winding machine 1 in question, the string core 7 is not bent, or only slightly bent, during the winding process, thus preventing any return to its original position. This reduces the occurrence of irregular tension in at least one winding layer.

[0022] The winding machine 1 in question allows for more precise winding. This enables the targeted and repeatable formation of a winding layer in which the adjacent turns of the first winding element 13 touch but are not pressed against each other. This allows the first winding element 13 to be produced with a predefinable and highly repeatable distance between the individual turns. This, in turn, allows for the precise adjustment of the internal damping of the music string 2. The internal damping of the music string 2 can be increased to a predefinable degree. This significantly influences the vibration behavior of the music string.

[0023] When sound is produced by bowing, the music string 2 is set into a sawtooth vibration. As can be seen in an FFT, for example, each sawtooth is composed of many sine waves with different frequencies, with the high-frequency vibrations forming the tip of the sawtooth. The tip of the sawtooth directly determines the proportion of different high-frequency vibrations. This sawtooth tip can be shaped as needed by changing the contacts or contact forces between the adjacent windings. This allows for the direct generation of significantly clearer and more distinct high-frequency harmonic overtones. The manufacturing process on the winding machine 1 therefore has a direct influence on the playing and tonal characteristics of the music string 2.

[0024] By surrounding the music string 2 around its circumference with the guide device 16 in such a way that the string core 7 or the string core 7 with the first winding element 13 arranged on it cannot "escape" the guide device 16, a predetermined contact pressure with which the first winding element 13 is pressed against the string core 7 can be set during the winding process with a certain independence from the tensile force 14 on the first winding element 13.

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

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

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

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

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

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

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

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

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

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

[0035] The winding machine 1 has at least one drive motor which drives the two clamping devices 4, 5 and is preferably connected to them via a gearbox. In particular, the winding machine 1 has two drive motors, preferably with rotational angle control, each of which drives one of the clamping devices 4, 5. The two clamping devices 4, 5 are driven such that they cause a clamped string core 7 to rotate about its longitudinal extent. If a first winding layer comprising the first winding element 13 is already arranged on the string core 7 and a further winding layer is to be arranged around or on the first winding layer, then the assembly of string core 7 and the first winding element 13 arranged on it will, of course, be set into rotation about its longitudinal extent. The string core 7 orAn intermediate product in the manufacture of the musical string 2 is not twisted or warped during rotation. The rotation takes place in a direction 28, which is in . Fig. 6 marked.

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

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

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

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

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

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

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

[0043] The guide device 16 has at least a first contact part 21 with a first contact surface 18 and a second contact part 22 with a second contact surface 19. Between the first contact part 21 and the second contact part 22, there is a slit-shaped feed opening 31 through which the first winding element 13 is guided to the string core 7 and the current winding point 17. The feed opening 31 is open wide enough to allow good access for the first winding element 13 and at the same time narrow enough to prevent, reduce, or control large deflections or vibrations of the winding element 13, thus maintaining a stable path for the first winding element 13.

[0044] The contact surfaces 18, 19, 20 are the surfaces of the respective contact parts 21, 22, 23, which face the string core 7 and / or touch it during the winding process. Furthermore, the first contact part 21 has a first feed opening surface 45. The second contact part 22 has a second feed opening surface 46. The two feed opening surfaces define the feed opening 31, both above and below, in the operating position.

[0045] The feed opening surfaces 45, 46 can be flat surfaces. Preferably, and as shown in the Figs. 6 and 7As shown, at least one of the feed opening surfaces 45, 46, preferably both feed opening surfaces 45, 46, and in particular the second feed opening surface 46, has at least one rounded section. In particular, it is provided that the second feed opening surface 46 and / or the first feed opening surface 45 have predefinably rounded edges. This facilitates the feeding or penetration of the first winding element 13 into the feed opening 31. Figs. 6 and 7 The first contact part 21 shows correspondingly rounded edges.

[0046] The clearance or receiving space between the contact parts 21, 22, 23 has a length – viewed in a direction along or parallel to the clamping element's axis of rotation 6 – which is preferably between 1% and 14% of the scale length of the musical string 2 to be manufactured. For example, this length can be essentially 11 mm, or approximately 1%, for a scale length of 1100 mm. For a scale length of 215 mm, it can be essentially 30 mm, or approximately 14%.

[0047] A first angle α exists between the first contact surface 18 and the second contact surface 19. This first angle α is adjustable. For this purpose, it is provided in particular that the first contact part 21 and / or the second contact part 22 is arranged or mounted so as to be pivotable or tiltable.

[0048] The first angle α – viewed along the clamping device's axis of rotation 6 – is between 55° and 125°, preferably between 75° and 105°. It has been shown that different first angles α have advantageous effects in the production of different musical strings 2, allowing for targeted influence on the sound and playability of the musical string 2. Thus, a wider range of adjustability for the winding machine 1 enables its use in a broader range of applications. Conversely, a narrower range of adjustability is easier to implement from a design and machine construction perspective.

[0049] Fig. 7Figure 16 shows a guide device, with two different positions of the second contact part 22 depicted. It has proven advantageous for setting and using different first angles α if the second feed opening surface 46 – viewed along the clamping device rotation axis 6 – is designed as a circular segment, an elliptical segment, or an exponential function. This allows similar throughput characteristics of the feed opening 31 to be achieved for different first angles α.

[0050] Preferred and as in Fig. 6 As shown, the guide device 16 further features a third contact part 23 with a third contact surface 20. This allows the winding process to be influenced and controlled even further.

[0051] The third contact part 23 can be arranged in different positions. In particular, it is provided that the third contact part 23 is arranged in abutting the second contact part 22. This offers advantages with regard to the manufacture of the guide device 16. Furthermore, a high accuracy of the guide device 16 can be achieved in this way. Preferably, the second contact part 22 and the third contact part 23 are formed in one piece. However, if longitudinal displacement of the third contact part 23 is provided, it is further preferred that a groove-like guide exists between the second and the third contact parts 22, 23.

[0052] Between the second contact surface 19 and the third contact surface 20, a second angle β exists – viewed along the axis of rotation of the clamping device 6. This second angle β is in particular between 65° and 155°, preferably between 75° and 105°. Certain second angles β have proven to be particularly advantageous in the manufacture of certain types of musical strings 2.

[0053] It is advantageous, in principle – with regard to the breadth of different application possibilities of the winding machine 1 – if the second angle β is adjustable. However, it is preferred that the second angle β be fixed. This allows for a considerably simpler design of the guide device 16. In particular, it is provided that certain guide devices 16 are each intended for the production of specific musical strings 2, and that these are exchanged as a whole on the winding machine 1 when switching from the production of one type of musical string 2 to the production of another type of musical string 2.

[0054] The individual contact parts 21, 22, 23 can be fixed machine parts – apart from the tiltability of the first or second contact part 21, 22. However, it is preferred that the exact position of at least one of the contact parts 21, 22, 23 is adjustable. Fig. 5 and 6Corresponding straight lines are drawn to illustrate these changes in position. If the guide device 16 has a third contact part 23, it is specifically provided that this part is displaceable along or parallel to the second contact surface 19. This assists in positioning the string core 7 in the guide device 16. Furthermore, this allows the contact pressure of the first winding element 21 on the string core 7 to be adjusted independently of the first tension force 14.

[0055] The guide device 16 is connected to the feed device 11 by means of a fastening device 39. This fastening device 39 can be designed as a stationary machine component.

[0056] On stringed instruments, the sound and handling (playability) of the instrument typically change when the musician moves their finger from a lower action (corresponding to a lower pitch and consequently a relatively long vibrating section of the string) to a higher action (corresponding to a higher pitch and a relatively short vibrating section of the string). Violins always have a fingerboard over which the string runs. The distance between the fingerboard and the string varies along the string's path from the nut and bridge. At the nut, this distance is relatively small. At the end of the fingerboard opposite the bridge, this distance is significantly larger, usually two to three times the distance at the nut.These varying distances influence the sound, handling, and excitation characteristics of string 2, and are a major reason for the different properties observed with different fundamental tones. Due to these varying distances, when the string is pressed against the fretboard, it is stretched differently depending on where on the fretboard it is plucked.

[0057] To compensate for this effect, individual parts of stringed and plucked instruments are adjusted accordingly. In particular, with instruments of the violin family, the fingerboard is often shaped differently along its length. This is called fingerboard hollowing. This adjustment must be made individually for each instrument by a luthier. This is a time-consuming, complex, and expensive process for the luthier.

[0058] In a further development of the invention, it can be provided that the distance between the contact parts 21, 22, 23 of the guide device 16 and the clamping device rotary axis 6 is adjustable. The winding machine 1 has an adjustable or adjustable and preferably force-controllable and / or displacement-controllable fastening device 39.

[0059] The fastening device 39 is designed such that the relevant distance or normal distance can be continuously and predictably adjusted along the length of the string core 7. In particular, such that this distance follows a predictable profile.

[0060] This allows the production of musical strings 2 which, at different vibrating lengths (i.e., when played in different positions), exhibit a sound and / or playability that differs significantly from conventionally manufactured musical strings 2. This is because the winding machine in question allows for different deflections than are possible with known manufacturing methods. Thus, a musical string 2 can be produced which, at specific fretted lengths or positions, exhibits predefined tonal characteristics and / or specific playability.

[0061] This allows for the creation of musical strings that are easily playable even on an instrument with a simple fretboard, i.e., a fretboard without a hollow cut. This can positively influence the sound of simpler and less expensive instruments. As a result, the costly work of an instrument maker can be avoided.

[0062] This allows the contact forces between adjacent windings to be very precisely adjusted and, above all, predictably varied along the length of the music string 2. This has a direct influence on the bending stiffness of the vibrating length of the music string 2. By adjusting the contact forces, the bending stiffness can be adapted to the vibrating string length, i.e., changed along the length of the music string 2.

[0063] The fastening device 39 includes a corresponding actuator. The actuator is, in particular, an electrically and / or pneumatically operated mechanical positioning unit. The electrically operated positioning unit is particularly comparable to a so-called servo from the field of model aircraft. A preferred pneumatically operated positioning unit is, for example, a pneumatic guide cylinder, a pneumatic piston cylinder, and / or a servo-pneumatic positioning system.

[0064] This allows the distance of the guide device 16 or its contact parts 21, 22, 23 to the clamping device rotation axis 6 to be set and predefinable.

[0065] According to a preferred embodiment of an actuator, it comprises both a pneumatic actuating unit and an electric actuating unit, the electric actuating unit being arranged on the pneumatic actuating unit. This allows for coarse adjustment using the pneumatic actuating unit, in which the guide device 16 is moved within a predefinable range around a target point. Subsequently, a so-called fine adjustment is performed using the electric actuating unit. The guide device 16 is thereby moved very precisely to the desired position.

[0066] In a method for manufacturing a musical string 2, in particular with a winding machine 1 as described herein, it is provided that a first end of a string core 7 of the musical string 2 is attached to a first clamping device 4, wherein a second end of the string core 7 is attached to a second clamping device 5, wherein a predetermined section of the string core 7 is guided in a guide device 16 with a first contact part 21 having a first contact surface 18 and a second contact part 22 having a second contact surface 19, wherein - viewed along the clamping device rotation axis 6 - the first angle α between the first contact surface and the second contact surface is between 55° and 125°, preferably between 75° and 105°, wherein the first angle α is set, wherein in a winding process by means of a feeding device 11 at least one first winding element 13 is fed to the string core 7 in a first feeding direction 15 through a slit-shaped feeding opening 31 between the first contact part 21 and the second contact part 22, wherein the feeding device 11 and the guide device 16 interact in such a way that at every point in time of the winding process an actual winding point 17 is formed in the guide device 16,where the first winding element 13 begins to be wound around the string core 7, wherein the first winding element 13 is tensioned with a predefinable tensile force 14, wherein the clamping devices 4, 5 are rotated about a clamping device rotary axis 6, wherein the guide device 16 together with the feed device 11 is moved parallel to the clamping device rotary axis 6 between the first clamping device 4 and the second clamping device 5.

[0067] The following are principles for understanding and interpreting the disclosure in question.

[0068] 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.

[0069] 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.
