Description

Schichtholzplatte zum Herstellen von auf Zug, Schlag- und Biegefestigkeit beanspruchten Werkzeugen Gegenstand der vorliegenden Erfindung ist eine Schichtholzplatte zum Herstellen von auf Zug-. Bruch-, Schlag- und Biegefestigkeit beanspruchten Werkzeugen, Maschinenteilen o. dgl. Es war bekannt. Schichth:olzplatten aus mehreren miteinander verbundenen Lagen von künstlich verdichtetem Naturholz und gewöhnlichem Naturholz herzustellen. Die Erfindung besteht in der der Eigenart der Holzlagen angepaßten Verbindung der Laben. Es wird nicht die bekannte Verbindung durch Nut und Feder oder Schw.albenschwanzverzapfung und auch nicht die Verbindung (Verleimung) von zwei glattvif Flächen angewendet, und es werden auch nicht, wie sonst üblich, beide Teile gerieft, sondern es wird nur das Hartholz gerieft und das geriefte Hartholz mit seinen Kanten in dass Weichholz eingedrückt. Diese Verbindung, die sich nur bei Hölzern von großer unterschiedlicher Härte ausführen läßt, hat den Vorteil der einfacheren Herstellung. Die Bindeflächen des verdichteten Naturholzes sind genutet, und es werden die freien Kanten beim Zusammenpressen unter hohem Druck in das unverdichtete, weichere Naturholz eingedrückt, wodurch auch eine Verzögerung der Leimfläche eintritt.Laminated wood panel for producing tensile, impact and flexural strength claimed tools The present invention is a laminated wood panel for producing on train. Tools subject to breakage, impact and flexural strength, Machine parts or the like. It was known. Layered wood: wooden panels made of several together connected layers of artificially compacted natural wood and ordinary natural wood to manufacture. The invention consists in that adapted to the nature of the wood layers Connection of the Laben. The well-known tongue and groove connection will not be used or dovetail joint and also not the connection (gluing) of Two smooth surfaces are applied, and neither, as usual, are both Parts grooved, but only the hardwood and the grooved hardwood are grooved with its edges pressed into the softwood. This connection that is only can be performed with woods of great different hardness, has the advantage of easier manufacture. The binding surfaces of the compacted natural wood are grooved, and the free edges are pressed together under high pressure into the uncompacted, softer natural wood is pressed in, which also causes a delay in the glue surface.

Die Zeichnung veranschaulicht ein Erzeugnis des nach dem netten Verfahren hergestellten Schichtenholzes, und zwar ein Maschinenglied in der Form eines Schlagstockes als Webschützentreiber als Beispiel; es zeigt: Fig. i eine Flachansicht des Schlagstockes. Fig. a einen senkrechten Schnitt nach Linie <1-i der Fig. i und Fig.3 einen Querschnitt nach Linie C-D Naturmaßstab).The drawing illustrates a product of the nice process made of laminated wood, namely a machine link in the shape of a baton as a web protection driver as an example; It shows: FIG. 1 a flat view of the baton. FIG. A shows a vertical section along line <1-i of FIG. I and FIG. 3 shows a cross section according to line C-D natural scale).

Aus Fig. :! ist ersichtlich, daß die kernartige Zwischenlage i aus unverdichtetein Naturliolz keilförmige Form hat, auf deren Flachseiten je eine Lage verdichtetes Naturholz z von gleichem Querschnitt (Dicke) aufgebracht ist. Die Fig.3 läßt erkennen, daß die Bindeflächen genutet sind und die Vernutüng in an sich bekannter Weise eine gröllere Bindefläche bietet.From Fig.:! it can be seen that the core-like intermediate layer i from uncompacted natural wood has a wedge-shaped shape with one layer on each flat side compacted natural wood z of the same cross-section (thickness) is applied. The Fig.3 shows that the binding surfaces are grooved and the reason is more familiar Way offers a larger binding surface.
