Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Geschoßfuhrungsringen gemäß Patent 306327. Nach dem letzteren besteht der Geschoßführungsring aus einem gepreßten Papierkern, der mit einem Metallüberzug, insbesondere Kupferbezug, derart versehen ist, daß-er zur Erhöhung der Haltbarkeit den Papierring an mehreren Stellen gitterartig durchdringt. Der Metallüberzug wird zweckmäßig auf galvanischem Wege auf die Papiermasse aufgebracht. Hierzu wird der Papierkern mit Graphit bestrichen, um ihn an seiner Oberfläche elektrisch leitend zu machen. Dabei besteht aber die Gefahr, daß bei der starken Beanspruchung der Ringe im Betriebe der Metallüberzug abblättert.The present invention relates to a method for the manufacture of bullet guide rings according to patent 306327. According to the latter the bullet guide ring consists of a pressed paper core with a Metal coating, in particular copper cover, is provided in such a way that it is used to increase the Durability penetrates the paper ring in several places like a grid. The metal coating is expediently applied to the paper pulp by electroplating. This is done the paper core coated with graphite to make it electrically conductive on its surface do. But there is a risk that the rings in the heavy use Plants of metal peeling off.
Nach dem neuen Verfahren wird dies dadurch vermieden, daß der Papiermasse schon bei ihrer Herstellung Graphit zugesetzt wird,According to the new method, this is avoided in that the paper pulp is already graphite is added in their production,
so daß sie durch und durch leitend wird. Es braucht daher bei der Verkupferung der Papierkern nicht mehr mit Graphit bestrichen zu werden. Vielmehr findet beim Verkupfern eine innige Verschmelzung des Metallüberzuges mit der Papiermasse statt; indem die Kupferteilchen oder sonstigen Metallteilchen in die Papiermasse eindringen. Die innige Verbindung zwischen Papierkern und Metallüberzug wird hierdurch wesentlich erhöht, und ein Abblättern des letzteren ist ausgeschlossen.so that it becomes conductive through and through. It therefore needs the paper core for copper plating no longer to be coated with graphite. Rather, there is an intimate fusion of the metal coating with copper plating with the paper pulp instead; by placing the copper or other metal particles in the Penetrate paper pulp. The intimate connection between the paper core and the metal coating is hereby significantly increased and the latter does not flake off.
Es ist bereits bekannt, Faserstoffmassen mit Graphit zu vermischen. Doch dient in diesem Falle der Graphit nur dazu, die Züge des Laufes der Feuerwaffe-zu schmieren.It is already known to mix pulp masses with graphite. But serves in In this case the graphite only serves to lubricate the barrel of the firearm.
