Description

[0001] The invention relates to a winding machine for 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 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 consisting of a V-shaped support which is arranged next to the winding point.

[0004] US 2001 / 0039722 A1 describes the attachment of a button-like end piece to the music string.

[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 8.

[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 8.

[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. 6the control device according to Fig. 3 in side view; Fig. 7 a second preferred embodiment of a guide device in axonometric view; Fig. 8 the control device according to Fig. 7 in the floor plan; Fig. 9 the control device according to Fig. 7 in elevation; Fig. 10 the control device according to Fig. 7 in side view; Fig. 11 a third preferred embodiment of the guide device in plan view.

[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 axis of rotation 6 in one direction of rotation, 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 axis of rotation 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, and at the current winding point 17 the string core 7 – viewed in the first feed direction 15 – rests against the guide device 16, wherein the guide device 16 – viewed in the plane formed by the first feed direction 15 and the clamping device rotation axis 6 – is tiltable.

[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] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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 11Figure 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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 clamping device 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 wound during rotation.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Due to the first winding element 13, which now pulls laterally on the string core 7, the string core 7 would be deflected or bent or deformed, as is known from the classical mechanics of the carrier on two support points.

[0040] 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.

[0041] 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.

[0042] The guide device 16 is designed and configured for the predetermined, section-by-section guidance of the string core 7. For this purpose, the guide device 16 has at least one contact part 21, and in particular a second contact part 22, which is designed and configured so that the length portion or section of the string core 7 rests against it during the winding process.

[0043] The feed device 11 and the guide device 16 are designed and interact in such a way that at every point during the winding process, a current winding point 17 is formed at which the first winding element 13 begins to be wound around the string core 7. The current winding point 17 is therefore located at or within the guide device 16 during the manufacture of the music string 2. A section of the string core 7 rests against the first contact part 21 of the guide device 16. In the preferred and in the Figs. 3 to 10 In the illustrated embodiments, the guide device 16 has a first and a second contact part 21, 22. The current winding point 17 is formed in the free space between the two contact parts 21, 22.

[0044] The first contact part 21 has a first string core contact surface 93 and / or the second contact part 22 has a second string core contact surface 94. The guide device 16 has a length – viewed in a direction along or parallel to the clamping device's axis of rotation 6 – which is the distance between the two string core contact surfaces 93, 94. In the second preferred embodiment according to Figs. 7 to 10 The distance between the two outer edges of the contact parts 21, 22 is the distance. This length is preferably between 1% and 14% of the scale length of the musical string 2 to be manufactured. For example, with a scale length of 1100 mm, this length can be essentially 11 mm, or approximately 1%. With a scale length of 215 mm, it can be essentially 30 mm, or approximately 14%.

[0045] The guide device 16 can have different shapes. Preferably, the guide device 16 has a T-shaped plan. The T-shaped plan comprises a mounting section 97 and a contact carrier section 99. The two sections 97 and 98 together form the T-shaped guide device 16 and are preferably manufactured as a single piece. The contact carrier section 99 carries the two contact parts 21 and 22, which are arranged or attached, in particular, to an underside of the contact carrier section 99 when viewed in its operating position. The mounting section 97 carries a connecting element receptacle 98, in particular a through-hole, and connects it to the contact carrier section 99. The contact carrier section 99 is preferably arranged substantially at a right angle to a longitudinal extension of the mounting section 97.

[0046] According to the first preferred embodiment, see Figs. 3 to 6 The contact parts 21, 22 are each designed as a combination of several cylinders. In each case, one cylinder 89 is designed as the primary contact part 21, 22, or arranged accordingly. In the preferred embodiment, two limiting elements 104, 105 are provided, which secure the position of the string core 7 on the cylinders 89 and prevent it from "jumping off". The cylindrical contact parts 21, 22 can be rotatably mounted.

[0047] According to the second preferred embodiment, see Figs. 7 to 10 The contact parts 21, 22 are each designed as rigidly fixed prisms. These preferably each have a guide groove 103, in particular a V-shaped one. The lateral edges or entry areas of the guide groove 103 for the string core 7 can be flattened.

[0048] The guide device 16 is designed to be tiltable, rotatable, or pivotable in the plane formed by the first feed direction 15 and the clamping device axis 6. This tiltability can be achieved in various ways, with two variants proving particularly advantageous.

[0049] In the first preferred embodiment, which is described in the Figs. 3 to 6 as shown, as well as the second embodiment, which is in the Figs. 7 to 10As shown, the guide device 16 is connected to the feed device 11 by means of a tiltable, rotatable, or pivotable connecting element 90. The connecting element 90 is preferably designed as a rotatable axis 91, which penetrates the connecting element receptacle 98 of the guide device 16. As an axis 91, no torque is transmitted via it, as would be the case with a shaft. Preferably, the guide device 16 is connected to the axis 91 by means of a ball bearing.

[0050] In the third preferred embodiment, which is described in Fig. 11As shown, it is specifically provided that the connecting element 90 is designed as a spring element 92. This allows a predefinable braking effect, which can also change depending on the angle of twist, to be implemented by selecting the appropriate spring element 92. This has proven advantageous in the manufacture of certain types of musical strings 2.

[0051] The spring element 92 can be designed as a separate or independent spring, with one end section of the spring being connected to, and in particular attached to, the guide device 16. The second end section of the spring is connected to, or attached to, the feed device 11. In this embodiment, the spring is an independent part.

[0052] According to an alternative preferred embodiment, the spring element 92 is designed as a part of the guide device 16, particularly as a single piece. In this embodiment, for example, a portion of the mounting section 97 may have a reduced cross-section, thereby enabling greater deflection. The guide device 16 can also be designed in two parts, with the mounting section 97 being made of a softer or more elastically compliant material than the contact element carrier section 99, which would be made of a stiffer material. In this case, the mounting section 97 would, in particular, be designed entirely as a spring.

[0053] The tilting movement of the guide device 16 will be subject to a certain resistance. In the case of mounting by means of an axle 91, this would be the frictional resistance. When the connection is formed by means of a spring, the resistance results from the spring constants. Nevertheless, in both different implementation variants, the respective resistance is solely determined by the design, but otherwise – excluding aging effects – they are the same. In a further development of the invention, it is preferably provided that the connecting element 90 has a resistance adjustment means for predefinable setting of a tilting resistance.

[0054] The pivoting motion is preferably unrestricted within its maximum deflection angles and therefore has no lateral limitations. However, in a further development, lateral stops can be provided to limit the deflection of the guide device 16 during or due to tilting.

[0055] The guide device 16, together with the feed device 11, is guided parallel to the clamping device rotation axis 6 between the first clamping device 4 and the second clamping device 5 and is moved during the winding process. The distance 96 between the connecting element 90 and a first core contact surface 93 of the first contact part 21 and / or a second core contact surface 94 of the second contact part 22 can remain constant.

[0056] With familiar strings on bowed and plucked instruments, the sound and handling / playability generally change when the musician moves their finger from a so-called low action (corresponding to a lower pitch and consequently a relatively long vibrating section of the string) to a so-called high action (corresponding to a higher pitch and a relatively short vibrating section of the string). Instruments of the violin family always have a fingerboard over which the string runs. The distance between the fingerboard and the string changes along the string's path from the nut and bridge of the instrument. At the nut, this distance is relatively small. At the end of the fingerboard opposite the bridge, this distance is significantly larger, usually two to three times the distance at the nut.These varying distances influence the sound, handling, and excitation characteristics of the musical string, and are a major reason for the different properties of different fundamental tones. Due to these varying distances, when the string is pressed against the fretboard, the string is stretched differently depending on where on the fretboard it is plucked.

[0057] To compensate for this effect, individual parts of stringed and plucked instruments are adapted accordingly. In particular, in instruments of the violin family, the fingerboard is often shaped differently along its length. This is called fingerboard hollowing.

[0058] This adjustment must be made individually for each instrument separately by an instrument maker. This is a time-consuming, complex, and costly process for the instrument maker.

[0059] It has been shown that varying the distance 96 of the guide device 16 – relative to the clamping element's axis of rotation 6 – offers more possibilities for selectively influencing the sound and playing characteristics of the music string 2. According to a preferred embodiment of the winding machine 1, the guide device 16 therefore includes a distance adjustment device 95 for predefinably setting a distance 96 between the connecting element 90 and a first string core contact surface 93. This distance adjustment device 95 is designed, in particular, for continuously adjusting the distance 96, preferably depending on the position of the guide device 16 between the first clamping element 4 and the second clamping element 5. This allows the sound and playability characteristics of the music string 2 to be predefinably adjusted via its length.

[0060] This allows the production of musical strings that, at different vibrating lengths (and therefore when played in different positions), exhibit a sound and / or playability that differs significantly from conventionally manufactured musical strings. This is because the winding machine in question allows for different vibration levels than are achievable with conventional methods. Thus, a musical string can be produced that, at specific fretted lengths or positions, possesses predetermined 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, thus eliminating the need for the costly work of a luthier.

[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] In a method for manufacturing a musical string 2 using a winding machine 1, the first end of the string core 7 of the musical string 2 is attached to the first clamping device 4. The second end of the string core 7 is attached to the second clamping device 5. During the manufacturing process, the two clamping devices 4 and 5, together with the attached string core 7, are rotated around the clamping device axis of rotation 6.

[0064] During the winding process, at least the first winding element 13 is fed to the string core 7 in a first feeding direction 15 by means of the feeding device 11. The first winding element 13 is tensioned with a predefinable tensile force 14 during the feeding process. During the winding process, the string core 7 is guided in a predefinite section of a guide device 16. At each point during the winding process, a current winding point 17 is formed at which the first winding element 13 begins to be wound around the string core 7, and thus at which the initial contact between the continuous first winding element 13 and the string core 7 takes place.

[0065] The guide device 16 is tiltably connected to the feed device 11. The feed device 11, 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.

[0066] According to a preferred embodiment of the method, it is provided that – during the movement of the guide device 16 between the first clamping device 4 and the second clamping device 5 – the distance 96 between a connecting element 90 – which connects the guide device 16 to the feeding device 11 – and a first string core contact surface 93 of the guide device 16 is predefinable, preferably continuously, depending on the position of the guide device 16 between the first clamping device 4 and the second clamping device 5. This allows the advantages described above for the distance adjustment device 95 to be achieved.

[0067] Furthermore, it is preferably provided that a tilting resistance of a connecting element 90 – which connects the guide device 16 to the feed device 11 – is predefinable, in particular depending on the position of the guide device 16 between the first clamping device 4 and the second clamping device 5, preferably continuously. This prevents certain vibrations from superimposing and forming a resonance. This improves stability during the manufacturing process.

[0068] The above-mentioned procedural steps do not have to be carried out in the order given above.

[0069] The following are principles for understanding and interpreting the disclosure in question.

[0070] 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.
