Description

Verfahren zur Herstellung von Kammplatten aus Kunsthorn Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Kammplatten aus solchem Kunsthorn, das aus Kasein, Brauereirückständen usw. gebildet ist. Die Erfindung besteht darin, daß in einer Materialplatte durch Pressen eine Anzahl von Kammplatten ger formt werden, die durch den Preßgrat verbunden sind und in diesem Zustande im Härtebade behandelt werden. Dadurch wird eine gleichmäßige Beschaffenheit der einzelnen Preßlinge erreicht und ein Verziehen und Verwinden der Katrimplatten während der Härtung vermieden, so daß tadelfreie, brauchbare Preßlinge zustande kommen.Process for the production of comb plates from synthetic horn The invention refers to a process for the production of comb plates from such artificial horn, that is formed from casein, brewery residues, etc. The invention consists in that a number of comb plates formed in a sheet of material by pressing which are connected by the press burr and in this state in the hardening bath be treated. This ensures that the individual compacts are uniform achieved and avoids warping and twisting of the Katrim plates during hardening, so that perfect, usable compacts are produced.

In der Zeichnung ist beispielsweise der Werdegang eines nach dem Verfahren hergestellten Kammes dargestellt, und zwar zeigt Abb. t eine Draufsicht auf eine geformte Materialplatte und Abb. a einen Querschnitt nach der LinieA-B der Abb. z.In the drawing, for example, is the career of a according to the method Manufactured comb shown, namely Fig. t shows a plan view of a shaped material plate and Fig. a a cross-section along the line A-B of Fig. z.

Patrize und Matrize sind so gearbeitet, daß die zwischen- den beiden Werkzeugen befindliche breiige Kunsthornmasse bei der Pressung eine Tafel bildet, die aus einer Anzahl Kammplatten a besteht, die durch den Preßgrat b untereinander verbunden sind, damit nicht jede einzelne Kammplatte aus der Form herausgenommen zu werden braucht. Die zusammenhängenden Stücke werden vor ihrer weiteren Verarbeitung in einem Härtebad behandelt, wobei durch die sie verbindende Haut die Gefahr des Verziehens der einzelnen Kammplatten a vermieden ist, wie dies bei der Behandlung einer einzelnen Plakette im Härtebad geschieht. Außerdem wird der infolge der Wirkung des Härtebades eintretende Schwund vermindert. Man braucht auch nicht jedes einzelne Stück aus dem Bade herauszunehmen, sondern die ganze Platte, und beschädigt so nicht die einzelnen Stücke, die, wenn sie einzeln in das Härtebad gelangen, mehr einlaufen, als wenn die zusammenhängenden Stücke in das Härtebad gebracht werden. Bei einem evtl. sich notwendig machenden Nachpressen nach dem Härtebade, also wenn sich die Platten verschoben haben, ist das Nachpressen der durch die Haut zusammenhängenden Stücke viel einfacher, als wenn jedes einzelne Stück nachgepreßt werden muß.The male and female molds are made in such a way that the between the two The pulpy synthetic horn compound in the tools forms a sheet when pressed, which consists of a number of comb plates a, which are interconnected by the press burr b are connected so that not every single comb plate is removed from the mold needs to become. The connected pieces are prior to their further processing treated in a hardening bath, whereby through the skin connecting them the risk of Warping of the individual comb plates a is avoided, as is the case with the treatment a single badge in the hardening bath happens. In addition, it will be a result of the effect the shrinkage occurring in the hardening bath is reduced. You don't need every single one Take the piece out of the bath, but the whole plate, and so does not damage it the individual pieces, which, when they get into the hardening bath individually, run in more, as if the connected pieces were brought into the hardening bath. At a possibly necessary re-pressing after the hardening bath, i.e. if the If plates have shifted, the re-pressing is the contiguous ones through the skin Pieces much easier than if every single piece has to be re-pressed.
