Description

Klavierbespannung. Zu Klaviersaiten wird bisher ausschließlich Draht aus normalem Kohlenstoffstahl (Tiegelgußstahl) verwendet, der rücksichtlich seiner Elastizitätsgrenze nur mit einer Spannung von höchstens i2o bis i3o kg/qmm aufgezogen werden kann und daher, namentlich für den Diskant, wegen der Kürze der Saiten mangelhafte klangliche Eigenschaften ergibt.Piano covering. So far, only wire has been used for piano strings made of normal carbon steel (crucible cast steel), which takes into account its Elasticity limit only raised with a tension of at most i2o to i3o kg / sqmm and therefore, especially for the treble, inadequate because of the shortness of the strings results in tonal properties.

Nach der Erfindung werden für die Saiten statt des gewöhnlichen Kohlenstoffstahles Edel- oder Spezialstahlsorten, sogenannter legierter Stahl, verwendet, wie z. B. Nickel, Nickelchrom-, Vanadium-, Nickelvanadiumu. dgl. Stahl, und diese Saiten werden mit einer höheren Spannung, von 15o bis etwa 25o kg/qmm aufgezogen, was wegen der höher liegenden Elastizitätsgrenze zulässig ist. Dadurch ist es möglich, bedeutend längere oder stärkere Saiten zu verwenden, wodurch sich trotz der erhöhten Spannung und der dadurch hervorgerufenen größeren Steifigkeit der Saiten eine überraschende Verbesserung der klanglichen Eigenschaften des Klaviers, des Tonvolumens und der Gesangfähigkeit ergibt.According to the invention, instead of the ordinary carbon steel for the strings Stainless or special types of steel, so-called alloy steel, are used, such as B. Nickel, nickel chromium, vanadium, nickel vanadium etc. Like. Steel, and these strings are with a higher tension, from 15o to about 25o kg / sqmm, which is because of the higher elastic limit is permissible. This makes it possible to be significant Use longer or stronger strings, which increases the tension and the resulting greater rigidity of the strings a surprising one Improvement of the sonic properties of the piano, the tone volume and the Singing ability results.
