Description

Verfahren zum Verbessern von Resonanzholz Es ist bekannt, die Resonanzfähigkeit des Holzes dadurch zu verbessern, daß es in seiner Länge und Breite ineinandergestauchtwird, wie es im Patent 343 iog und in dem Zusatzpatent 368 187 beschrieben ist.Method for improving resonance wood It is known that the resonance ability to improve the wood by compressing it in length and width, as described in patent 343 iog and in additional patent 368 187.

Die Neuerung besteht nun darin, daß das Resonanzholz nur in der axialen Richtung, das heißt in der Faserrichtung, gestaucht wird. Es wird hierdurch ermöglicht, das Holz für ebene Resonanzplatten in einfacher Weise zu verbessern, dadurch, daß die Teile z. B. einerKlavierresonanzplatte einzeln in ihrer Längsrichtung gestaucht und dann zu einer Platte miteinander verbunden werden.The innovation now consists in the fact that the resonance wood is only in the axial Direction, that is, in the fiber direction, is compressed. This enables to improve the wood for flat soundboards in a simple manner, in that the parts z. B. a piano resonance plate individually compressed in its longitudinal direction and then joined together to form a plate.

Das Stauchen kann dadurch erfolgen, daß das Resonanzholz in der Faserrichtung mittels einer geeigneten Vorrichtung zusammengepreßt, in dieser Richtung also etwas verkürzt wird, in der Pressung sodann erwärmt wird, so daß das Holz nach dem Erkalten seine Veränderung, die es durch das Stauchen erfahren hat, behält.The upsetting can take place in that the resonance wood in the grain direction compressed by means of a suitable device, something in this direction is shortened, is then heated in the pressing, so that the wood after cooling retains the change it has undergone as a result of the upsetting.

Das Verfahren kann angewendet werden sowohl an fertig zugeschnittenen Hölzern wie auch an Rohhölzern, die erst nach dem Stauchen auf zweckentsprechende Längen und Dicken verarbeitet werden. Durch sehr lange Einwirkung der Pressung kann das Stauchen auch auf kaltem Wege erfolgen.The method can be applied to both pre-cut Wood as well as raw wood, which only after compression on appropriate Lengths and thicknesses can be processed. By applying the pressure for a very long time, the upsetting can also be carried out in a cold way.

Das Festhalten der in axialer Richtung zusammengepreßten Hölzer kann auch dadurch erfolgen, daß sie mit in axialer Richtung gehenden Leisten oder Rippen verleimt werden, die ein Zurückgehen in die alte Lage verhindern.Holding the wood compressed in the axial direction can also take place in that they are made with strips or ribs extending in the axial direction be glued, which prevent a return to the old position.

PATENTANSPRÜCHE: i. Verfahren zur Verbesserung von Resonanzholz, dadurch gekennzeichnet, daß das Resonanzholz in der Faserrichtung zusammengepreßt und gleichzeitig so stark erwärmt wird, daß es nach dem Erkalten die bewirkte Stauchung behält. a. Verfahren nach Anspruch i, dadurch gekennzeichnet, daß das Resonanzholz ohne Anwendung von Wärme so lange der Pressung ausgesetzt bleibt, bis nach dem Aufheben der Pressung genügende Stauchung zurückbleibt. 3. Verfahren nach Anspruch i und 2, dadurch gekennzeichnet, daß das zusammengepreßte Holz in bekannter Weise mittels Holzleisten oder Rippen in der Faserrichtung verleimt und dadurch in der gepreß ten Form erhalten bleibt.PATENT CLAIMS: i. Method of improving resonance wood, thereby characterized in that the resonance wood is compressed in the grain direction and simultaneously is heated so much that it retains the compression caused after cooling. a. Method according to claim i, characterized in that the resonance wood without application remains exposed to the pressure of heat until after the pressure is released sufficient compression remains. 3. The method according to claim i and 2, characterized in that that the compressed wood in a known manner by means of wooden strips or ribs glued in the grain direction and thus retained in the pressed form.
