Description

Verfahren zum Herstellen von Schallkörpern. Die Erfindung bezieht sich auf Verfahren zur Herstellung von Schallkörpern aus Harzen, Gespinstfasern u. dgl. und geeigneten Lösungsmitteln.Method for producing sound bodies. The invention relates focus on processes for the production of sound bodies from resins, woven fibers and the like and suitable solvents.

Sie besteht darin, daß der aus solchen Stoffen hergestellte Körper, nachdem er erhärtet ist, einige Zeit auf eine Temperatur, die etwas oberhalb seines Siedepunktes liegt, gebracht und dann durch Pressen zwischen geeigneten erhitzten Platten in die endgültige Form gebracht wird.It consists in the fact that the body made of such substances, after it has hardened, for some time to a temperature slightly above its own Boiling point is brought and then heated by pressing between suitable Plates are brought into their final shape.

Durch dieses nachträgliche Sieden wird erzielt, daß sämtliche Rückstände des Lösungsmittels und von Flüssigkeit aus der Masse entfernt werden, so daß der Schallkörper eine größere Härte und Festigkeit aufweist als ohne nachträgliche Erhitzung. Durch die größere Härte wird aber eine größere Schwingungsmöglichkeit und demgemäß auch eine bessere Klangfülle erzeugt.This subsequent boiling ensures that all residues of the solvent and liquid are removed from the mass, so that the Sound body has a greater hardness and strength than without subsequent heating. Due to the greater hardness, however, there is a greater possibility of oscillation and accordingly also produces a better sonority.
