Abstract

The superposed veneered layers (2, 3, 4) each have a thickness of between 1 and 3 millimetres, and are formed by placing them one after the other around a mould (1), dimensional in accordance with the required inner dimensions of the finished pipe. The successive layers (2, 3, 4) are pref. placed around the inner mould (1) such that the joint (20, 30, 40) in each is offset from the other joints (20, 30, 40), each layer (2, 3, 4) being held in place around the mould (1) by a gauze bandage (W, W').

Description


  
 



    Die Erfindung betrifft eine Holzröhre für Musikinstrumente, wie Alphömer, Büchel, Holzpfeifen, Orgelpfeifen und dergleichen, sowie ein Verfahren zur Herstellung dieser Holzröhre. The invention relates to a timber tube for musical instruments, such as Alphömer, Büchel, wood pipes, organ pipes and the like, and a method for manufacturing these wood tube.



    Holzröhren für Musikinstrumente, insbesondere für solche Blasinstrumente, deren Hohlraum keine zylindrische Form aufweist und daher nicht durch einfaches Bohres erhalten werden kann, werden in der Regel dadurch hergestellt, dass man ein geeignet vorbereitetes Holzstück der Länge nach teilt, die beiden Hälften entsprechend der gewünschten Hohlraumform aushöhlt und sie zu einer Röhre vereinigt. Wood tubes for musical instruments, in particular to those instruments whose cavity has no cylindrical shape and therefore can not be obtained by simply Bohres are generally produced in that one divides a suitable prepared wood pieces longitudinally, the two halves corresponding to the desired cavity shape hollowing and unites them into a tube.  Diese bekannte Herstellungsweise ist umständlich. This known production method is cumbersome.  Es ist ausserdem schwierig, beim Aushöhlen die beiden Hälften gleich und nach einer besonderen Längsschnittkurve so auszuhöhlen, dass das aus der Röhre gefertigte Instrument gut gestimmt ist. It is also difficult to erode when hollowing the two halves of the same and to a particular longitudinal section curve so that the instrument made of the tube is well tuned.  In der Regel besteht auch das Problem, dass bei mehreren Instrumenten eine erhebliche Abweichung der Stimmung von Instrument zu Instrument auftritt. As a rule, there is also the problem that several instruments a considerable deviation of the mood of the instrument appears to instrument.  Es kommt zudem nicht selten vor, dass die Stimmung eines Instrumentes zwar in einem Frequenzbereich, z. It also is not uncommon that the mood of an instrument while in a frequency range, eg.

   B. im höheren, mittleren oder tiefen Tonbereich, gut ist, in den übrigen aber mittelmässig oder schlecht ausfällt. As in the higher, medium or low tone range is good, but mediocre or bad fails in the other.  Selbst bei grösster Sorgfalt der Herstellung können sich Stimmungs Veränderungen auch nachträglich durch sogenanntes Arbeiten des Holzes ergeben. Even with the greatest care to the manufacture Mood changes may occur even later by so-called movement of the wood.



    Der Erfindung liegt die Aufgabe zugrunde, die geschilderten Nachteile zu vermeiden. The invention has for its object to avoid the disadvantages.



    Zur Lösung dieser Aufgabe wird eine Röhre für Musikinstrumente vorgeschlagen, welche dadurch gekennzeichnet ist, dass ihre Wandung aus mehreren miteinander verleimten Furnierholzschichten besteht. To achieve this object, a tube for musical instruments is proposed, which is characterized in that its wall a plurality of glued together veneer layers.



    Die Fasern aller Schichten sollen dabei in Röhrenlängsrichtung verlaufen. The fibers of all layers are in this case run in the tube longitudinal direction.



    Die einzelnen Furnierholzschichten können z. The individual veneer layers such.  B. eine Dicke von 1 bis 3 mm aufweisen. Example, have a thickness of 1 to 3 mm.  Die Röhren können ohne weiteres Längen von bis zu 4 m und mehr erreichen. The tubes can be up to 4 m and reach more readily lengths.



    Das erfindungsgemässe Verfahren zur Herstellung einer erfindungsgemässen Holzröhre ist dadurch gekennzeichnet, dass man ein dem Hohlraum der Röhre entsprechend dimensioniertes Kernmodell herstellt und darauf Furnierholzschichten übereinander verleimt. The inventive method for manufacturing of an inventive timber tube is characterized in that one produces a correspondingly dimensioned cavity of the tube core model and superimposed glued thereon veneer layers.



    Es ist vorteilhaft, vorerst von jeder Schicht ein Schnittmuster der Abwicklung vorzubereiten und jede Schicht danach zuzuschneiden. It is advantageous to prepare for the time being of each layer of a pattern processing and tailor each layer thereafter.



    Vorzugsweise umwickelt man wenigstens die erste auf das Kernmodell aufgelegte Schicht mit geeignetem Material, z. Preferably, at least the first wrapped on the core model launched layer with suitable material, such.  B. B.   



   Gaze, um sie dem Kernmodell besonders gut anzupassen. Gauze particularly well adapted to the core model.



    Die Stossstellen der Schichten sollen aus Haltbarkeitsgründen zueinander versetzt angeordnet werden. The abutment points of the layers are to be arranged offset from durability reasons to each other.



    Als Holz kann ein für das betreffende Instrument übliches Holz verwendet werden, z. As wood a common instrument for that wood can be used for.  B. Tannenholz für Alphornröhren. B. pine for alphorn tubes.



    Ein wasserfester Leim, zB aus Kunststoff, ist zum Verleimen der Furnierschichten besonders geeignet. A water-resistant glue, for example made of plastic, is particularly suitable for gluing of the veneer layers.



    Die Schichtverleimung bietet grösste Gewähr für gute Masshaltigkeit der Röhre, so dass Veränderungen und dadurch bedingte Abweichungen der Stimmung nicht zu erwarten sind. The Multiple layers offers biggest guarantee for good dimensional stability of the tube so that changes and therefore are not expected deviations of humor.



   Durch die präzise Ausbildung des Hohlraumes, die durch die beschriebene Herstellungsweise besonders gut erzielbar ist, lässt sich von Anfang an eine hochpräzise und reproduzierbare Stimmung im gesamten Frequenzbereich erreichen. Through the precise formation of the cavity that is well achieved by the described method of production especially, can be achieved from the outset a highly accurate and reproducible atmosphere in the entire frequency range.



    Ein weiterer Vorteil der Erfindung liegt darin, dass man die altgewohnte Gesamtform und somit den äusseren, oft traditionsgebundenen Aspekt der Instrumente nicht zu verändern braucht, und trotzdem durch die präzise und saubere Form des Röhrenhohlraums eine bisher unbekannte Qualitätssteigerung erreichen kann. Another advantage of the invention is that it is not necessary to change the old habit overall shape, and thus the outer, often tradition-bound aspect of the instruments, and can still reach through the precise and clean shape of the tube cavity a previously unknown quality improvement.  Auch die Masshaltigkeit ist den bisherigen Röhren weit überlegen, was ebenfalls qualitätssteigernd wirkt. The dimensional accuracy is superior to previous tubes wide, which also acts to improve their quality.



    Die Erfindung soll nachstehend anhand der rein schematischen Zeichnung beispielsweise näher beschrieben werden. The invention will be described for example in detail below with reference to the purely schematic drawings.  Es zeigen: Show it:

   3 ähnlichen Schnittdarstellungen. 3 similar sectional views.



    Das Kernmodell 1 ist aus Holz gefertigt, wobei leicht einzusehen ist, dass die der gewünschten Innenform der Röhre entsprechende Gestaltung dieses Kernmodells 1 einfacher durchzuführen ist, als das sonst übliche Aushöhlen der beiden Röhrenhälften. The core model 1 is made of wood, being easy to see that this core model 1 is easier to carry out the desired internal shape of the tube corresponding design as the usual hollowing of the two tube halves.  Ausserdem besteht der Vorteil, dass das Kernmodell 1 praktisch unbeschränkt für weitere Röhren wiederverwendbar ist. In addition, there is the advantage that the core model 1 is practically unlimited reusable for more tubes.  Soweit sich bei Versuchen zeigen sollte, dass ein in Herstellung begriffenes Kernmodell stellenweise noch zu dick ist, kann es leicht durch weitere Bearbeitung abgetragen werden. If it should be shown in experiments that a begriffenes in manufacturing core model is at times too thick it can be removed by further processing easily.  Umgekehrt kann man auch zu dünn geratene Stellen durch entsprechenden Materialauftrag, wie Spachtelmasse, Klebband und dergleichen, korrigieren. Conversely, it is also too thin guessed points by appropriate application of material as filler, adhesive tape and the like, correct.  So kann ein perfektes Kernmodell 1 erhalten werden. So a perfect core model 1 can be obtained.



    Um die Anbringung der einzelnen Furnierschichten 1, 2 und 3 zu erleichtern, kann man, wie in Fig. 2 dargestellt, ein Schnittmuster A für jede Furnierschicht herstellen, wobei man die Endbereiche nicht unbedingt korrekt runden muss, weil eine diesbezügliche Nachbearbeitung der fertigen Röhre leicht durch Beschneiden der Ende erfolgen kann. To facilitate the attachment of the individual veneer layers 1, 2 and 3, one can, as shown in FIG. 2, to produce a pattern A for each veneer layer, with one the end portions do not necessarily correctly round must, because a relevant post-processing of the finished tube slightly can be done by cutting down its end.



    Die einzelnen Furnierschichten 1 bis 3 (es könnten auch nur zwei odermehr als drei sein) werden im Zuge ihrer Anbringung (vgl. später zu Fig. 4) so plaziert, dass ihre Stossstellen 20, 30, 40 gegenseitig versetzt zu liegen kommen, wobei die in Fig. 3 gezeichneten Versatzwinkel variabel sind. The individual veneer layers 1 to 3 (it might also be just two or more than its three) are in the course of their mounting (cf.. Later to Fig. 4) so positioned that their joint locations 20, 30, 40 mutually offset come to lie, said 3 drawn offset angle are variable in Fig..



    Bei der Herstellung der Röhre geht man, wie in Fig. 4 ersichtlich, vor: Wie in Fig. 4 bei a gezeigt, wird vorerst das Kernmodell 1 vorbereitet, wobei die Oberfläche mit geeigneten Trennmitteln behandelt werden kann. In the production of the tube to go, as shown in Figure 4 can be seen before:.. As shown in Figure 4 at A, the core model 1 is initially prepared, the surface can be treated with suitable release agents.  Nun wird (vgl. b) die erste Furnierschicht 2 aufgebracht und vorzugsweise durch eine Bandage (insbesondere Gaze und dergleichen) am Kernmodell fest angepresst. Now (see FIG. B) applied the first veneer layer 2, and preferably is pressed firmly by a bandage (in particular, gauze and the like) to the core model.  Die Bandage ist hier mit W bezeichnet. The support is here designated W.  Ein Leimauftrag kann sowohl vor als auch während bzw. nach dem A glue application can be both before and during or after
 Bandagieren, dh Umwickeln, erfolgen. Bandaging, ie wrapping done.  Es wird das Stadium c erreicht. It reached the stage c.  Nun braucht nicht erst gewartet zu werden, bis die erste Schicht sich verfestigt hat, sondern man kann gleich, wie bei d gezeigt, die zweite Schicht 3 aufleimen und gewünschtenfalls wieder mit einer Bandage W' fixieren. Now needs does not wait to be, has until the first layer solidifies but can be the same, as shown at d, Glue the second layer 3 and 'fix, if desired, again with a bandage W.  Dann erfolgt, wie bei e gezeigt, das Aufleimen der Schicht 3, welche hier die letzte Schicht darstellen soll. Then, as shown at e, the gluing of the layer 3, which is intended to represent the last layer here.

   Auch sie kann (aber ohne Leim) durch eine Bandage gehaltert werden, wobei man nach dem Abbinden des Leims die Bandage entfernen kann. Also, they can be supported by a bandage (without glue but), it being possible to remove the bandage after setting of the glue.

 

    Wenn, wie hier angenommen werden soll, ein Alphorn herzustellen wäre, können dessen Teilrohre einzeln oder an einem Stück hergestellt werden. would be if, as will be assumed here produce a Alphorn, can be used individually or the component tubes are manufactured in one piece.  Sie können hierauf die übliche Aussenwicklung, Kupplungsmuffen und Endstücke (Mundstück und Trichter) erhalten und fertig veredelt werden. You can then be obtained outside the usual winding, coupling sleeves and end pieces (mouthpiece and funnel) and finished refined.

The core model 1 is made of wood, being easy to see that this core model 1 is easier to carry out the desired internal shape of the tube corresponding design as the usual hollowing of the two tube halves. In addition, there is the advantage that the core model 1 is practically unlimited reusable for more tubes. If it should be shown in experiments that a begriffenes in manufacturing core model in places is still too thick, it can be removed by further processing easily. Conversely, it is also too thin guessed points by appropriate application of material as filler, adhesive tape and the like, correct. So a perfect core model one can get.

To facilitate the attachment of the individual veneer layers 1, 2 and 3, one can, as shown in FIG. 2, to produce a pattern A for each veneer layer, with one the end portions do not necessarily correctly round must, because a relevant post-processing of the finished tube slightly can be done by trimming the end.

The individual layers of veneer 1 to 3 (it might also be just two or more than its three) are in the course of their mounting (see FIG. Later to Fig. 4) placed so that their butt joints 20, 30, 40 mutually offset come to lie, with the 3 drawn offset angle are variable in Fig..
