Description

Die Erfindung betrifft ein Verfahren zur Herstellung des Resonanzkörpers von Streichinstrumenten, insbesondere ei- .ner Geige und ein Gerät zum Formen des Bundes der Saiten eines Resonanzkörpers von Streichinstrumenten, insbesondere einer Geige.The invention relates to a method for producing the resonance body of string instruments, in particular a violin, and a device for shaping the fret of the strings of a resonance body of string instruments, in particular a violin.

Das bekannte und allgemein angewandte Verfahren zum Bau einer Geige und anderer Streichinstrumente besteht im Anpassen sämtlicher Elemente bei deren Montage mit Ausnahme des Zusammenklebens des Bassbalkens mit der oberen Platte, wo die Spannungen eingeführt bzw. die Vorspannungen erzeugt werden. Der Bassbalken wird vor dem Zusammenkleben derart gebogen, daß er sich an die Fläche der oberen Platte anpaßt. Die richtigeGestalt. des Bundes der Saiten wird beim Warmverformen der Saiten erzielt. Beim Formen wird in der Regel eine Aussen- oder Innenform angewandt. Eine derart fixierte Krümmung der Saiten und der Leisten gewährleistet einen spannungsfreien Zustand des Bundes vor dessen Ankleben an die eng angepaßte obere und untere Platte.The known and generally used method for building a violin and other stringed instruments consists in adapting all elements during their assembly, with the exception of gluing the bass bar to the top plate, where the tensions are introduced or the pretensions are generated. Before gluing, the bass bar is bent in such a way that it adapts to the surface of the top plate. The right shape. of the fret of the strings is achieved when the strings are thermoformed. An outer or inner shape is usually used for molding. Such a fixed curvature of the strings and the strips ensures a tension-free state of the fret before it is glued to the closely matched upper and lower plate.

Ein Nachteil des bekannten Verfahrens besteht darin, daß die nach dem herkömmlichen Verfahren ausgeführte obere Platte die von der Spannung der Saiten herrührenden Druck- .kraft übernimmt. (W. Kaminski, J. Swirek "Lutnictwo" - PWM, Kraköw, 1972).A disadvantage of the known method is that the upper plate made according to the conventional method takes over the pressure. Force resulting from the tension of the strings. (W. Kaminski, J. Swirek "Lutnictwo" - PWM, Krakow, 1972).

Entsprechend den Untersuchungen von Backhaus hängt die Qualität des Instrumentes von der Formantenverteilung in seinem Spektrum ab. Das Instrument ist desto besser, je näher die Bereiche der stärksten Formanten an 4000 Hz angenähert sind (S. Golechowski, N. Drobner - Akustyka muzyczna, PWN, 1953).Eine nach dem bekannten Verfahren hergestellte Geige besitzt diese Eigenschaft nicht und die Bereiche der stärksten Formanten befinden sich unter 3000 Hz.According to the studies by Backhaus, the quality of the instrument depends on the formant distribution in its spectrum. The closer the ranges of the strongest formants to 4000 Hz, the better the instrument Approximate (S. Golechowski, N. Drobner - Akustyka muzyczna, PWN, 1953). A violin made according to the known method does not have this property and the areas of the strongest formants are below 3000 Hz.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren zur Herstellung des Resonanzkörpers eines Streichinstruments anzugeben, mit dem es gelingt, den Bereich starker Formanten in das Frequenzintervall von 3000 bis 4000 Hz zu verschieben.The invention is therefore based on the object of specifying a method for producing the resonance body of a stringed instrument, with which it is possible to shift the range of strong formants into the frequency interval from 3000 to 4000 Hz.

Das Ziel wird durch ein neues Herstellungsverfahren, das in der Einführung der Vorspannungen in den Resonanzkörper zur Erreichung der die obere Platte streckenden Kräfte, welche die Rolle einer Membrane spielen soll, besteht so- - wie durch den Einsatz eines neuen Gerätes zum Formen des Bundes der Saiten erreicht.The goal is achieved by a new manufacturing process, which consists in the introduction of the prestressing in the resonance body to achieve the forces that stretch the upper plate, which is supposed to play the role of a membrane, as well as in the use of a new device for forming the federal government Strings reached.

Das erfindungsgemäße Verfahren besteht darin, daß dem Resonanzkörper durch die Ausbildung der unteren und oberen Platte in Form eines Bogens, der jeweils in entgegengesetzter Richtung zu der durch das Aufziehen der Saiten hervorgerufenen Biegetendenz gebogen ist, und durch federnde Gestaltung der Bünde der Saiten eine Vorspannung verliehen wird, wozu nach dem federnden Vorbiegen der Saiten die Leisten angeklebt, der Bund der Saiten bis in die Endgestalt elastisch geformt, anschließend der Bund der Saiten mit der oberen, in Form eines Bogens mit eingeklebtem Baßbalken ausgestalteten Platte zusammengeklebt und schließlich der Resonanzkörper durch die untere, ebenfalls bogenförmige Platte abgeschlossen wird.The method according to the invention is that the resonance body by the formation of the lower and upper plate in the form of an arc, which is each bent in the opposite direction to the bending tendency caused by the winding of the strings, and by resilient design of the frets of the strings the strips are glued on after the elastic pre-bending of the strings, the waistband of the strings is elastically shaped to the final shape, then the waistband of the strings is glued together with the upper plate, which is designed in the form of an arch with a glued-in bass beam, and finally the sound box through the lower , also arcuate plate is completed.

Das Gerät zum Formen des Bundes der Saiten eines Resonanzkörpers besteht erfindungsgemäß aus einem ovalen Ring mit mindestens vier in den Ringachsen angeordneten Löchern. Der Ring ist vorzugsweise mit vier Gewindehülsen für Druckschrauben und Korrekturschrauben in den Lochstellen versehen.The device for forming the fret of the strings of a resonance body according to the invention consists of an oval ring with at least four holes arranged in the ring axes. The ring is preferably provided with four threaded sleeves for pressure screws and correction screws in the holes.

Ein Vorteil des erfindungsgemäßen Verfahrens besteht in der Ausbildung des Resonanzkörpers mit Vorspannungen, die die Stellen von starken Verstärkungen (Formanten) nach höheren Frequenzen hin verschieben. Dadurch wird der Re-sonanzkörper zu einem Hochpaß umgesetzt, wodurch.die akustischen Bedingungen verbessert werden. Dies resultiert daraus, daß die Verstärkungskomponenten, die stärker harmonisch sind und höhere Frequenzen aufweisen, die Aussendung grösserer Energien ermöglichen, was eine bessere Tragfähigkeit des Instruments sichert. Durch das erfindungsgemäße Ge-rät kann dem Bund der Seiten bei Erhaltung seiner Elastizität eine Form gegeben werden, welche es erlaubt, derartige Kräfte zu erzielen, die den Resonanzkörper längs der Achse strecken.An advantage of the method according to the invention is the formation of the resonance body with pretensions which shift the points of strong reinforcements (formants) towards higher frequencies. Thereby, the R-e sonanzkörper is converted to a high-pass filter, wodurch.die acoustic conditions are improved. This results from the fact that the amplification components, which are more harmonic and have higher frequencies, allow the transmission of larger energies, which ensures a better carrying capacity of the instrument. E-advises by the inventive G can be given a shape to the collar of the sides while maintaining its elasticity, which makes it possible to achieve such forces that stretch the resonance body along the axis.

Der Erfindungsgegenstand ist anhand eines Ausführungsbeispiels in der Zeichnung dargestellt, die eine Ansicht des Gerätes zum Formen des Bundes der Seiten von Streichinstru-, menten zeigt.The subject matter of the invention is illustrated with the aid of an exemplary embodiment in the drawing, which shows a view of the device for forming the federal government of the sides of stringing instruments.

Das Gerät besteht aus einem ovalen Ring 1 mit acht Gewindelöchern 2 samt Gewindehülsen 3 für Druckschrauben 3, 4, 5 und Korrekturschrauben 6.The device consists of an oval ring 1 with eight threaded holes 2 together with threaded sleeves 3 for pressure screws 3, 4, 5 and correction screws 6.

Das Verfahren zur Ausbildung des Resonanzkörpers einer Geige ist wie folgt:

  • Die obere Platte des Resonanzkörpers wird in Form eines Bogens ausgeführt, der entgegengesetzt zu der Biegetendenz des Resonanzkörpers an den Saiten gebogen ist. Nach der nicht-ganz elastischen Vorbiegung der Saiten werden Leisten angeklebt, damit beim nächsten Verfahrensschritt ebenfalls elastisch der Bund bzw. die Zarge der Saiten bis auf die Endgestalt geformt werden kann. Der Bund der Saiten wird dann mit der oberen Platte zusammengeklebt, die in Form eines Bogens mit nach einem herkömmlichen Verfahren eingeklebtem Baßbalken ausgeführt worden ist. Nach dem Verkleben der beiden Elemente wird die obere Platte durch den Bund der Saiten mit den Leisten gestreckt.
The procedure for forming the sound box of a violin is as follows:
  • The top plate of the resonance body is designed in the form of an arc which is bent on the strings in the opposite direction to the bending tendency of the resonance body. After the not fully elastic pre-bending of the strings, strips are glued on, so that in the next process step the collar or the frame of the strings can also be resiliently formed to the final shape. The fret of the strings is then glued together with the top plate, which has been made in the form of an arc with a bass beam glued in according to a conventional method. After the two elements have been glued, the top plate is stretched through the strings with the strips.

Der Resonanzkörper wird durch die untere Platte abgeschlossen, die in Form eines in entgegengesetzter Richtung zu der Biegetendenz des Resonanzkörpers durch den Saitenaufzug gebogenen Bogens ausgeführt ist. Nach dem Zusammenkleben wird aus dem Resonanzkörper das Distanzstück herausgenommen.The resonance body is closed by the lower plate, which is designed in the form of an arc bent in the opposite direction to the bending tendency of the resonance body by the string elevator. After gluing, the spacer is removed from the sound box.

Mit dem Gerät wird wie folgt verfahren:

  • Der Bund der Saiten ohne Leisten, verklebt mit den Platten, wird in den Ring 1 eingelegt. Durch Anziehen der Druckschrauben 5 wird der Taillenumriß geformt. Schließlich werden nach dem Ankleben der Leisten an den Bund die Druckschrauben 4 und darauf die Korrekturschrauben 6 zur Erreichung der Endgestalt angezogen. Die Korrekturschrauben 6 dienen zur Korrektur eventueller Abweichungen der Gestalt des Bundes der Saiten von der symmetrischen Form. Zum Schutz der Oberfläche der Saiten vor einer Beschädigung werden Unterlagscheiben 7 und 8 zwischen dem Werkstück und den Stirnflächen der Schrauben eingesetzt.
The device is operated as follows:
  • The fret of the strings without strips, glued to the plates, is placed in ring 1. The waist outline is formed by tightening the pressure screws 5. Finally, after the strips have been glued to the collar, the pressure screws 4 and then the correction screws 6 are tightened to achieve the final shape. The correction screws 6 serve to correct any deviations in the shape of the fret of the strings from the symmetrical shape. To protect the surface of the strings from damage, washers 7 and 8 are inserted between the workpiece and the end faces of the screws.
