 EMI1.1 
 
 EMI1.2 
 zur magnetischen Flussrichtung angeordneten Drähten entsteht. Als Bindemittel zum Zusammenhalten der Drähte sind bisher Stoffe wie Harz, Bakelit, Schellack usw. vorgeschlagen worden. Aber meist sind diese Bindemittel der Beanspruchung des   Stückes   beim Zersägen nicht gewachsen, sondern die einzelnen Drahtteilchen splittern aus, und die gewünschte Form der Stücke geht verloren. 



   Nach der Erfindung lässt sich nun dieses Aussplittern dadurch vermeiden, dass man das Bindemittel in Verbindung mit einem Faserstoff zur Anwendung bringt. Dies kann auf verschiedene Weise geschehen. Man kann beispielsweise die zur Verwendung kommenden Drähte zunächst vollständig oder teilweise mit einem Faserstoff umspinnen und erst dann mit einem der genannten Bindemittel vereinigen, oder man kann auch den Faserstoff erst vor oder beim Aufbau des zur Zerkleinerung bestimmten Stückes zusetzen. Selbstverständlich können auch beide Massnahmen gleichzeitig angewandt werden. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Magnetkernen für Pupinspulen, bei denen als magnetisches   Material miteinander verkittete   Drähte senkrecht zum magnetischen Flusse angeordnet sind, dadurch gekennzeichnet, dass zwecks Erhöhung der mechanischen Festigkeit des Kernes zwischen die Drähte neben den an sich bekannten Bindemitteln Faserstoffe gebracht werden.

 EMI1.1
 
 EMI1.2
 wires arranged to the direction of the magnetic flux arises. Substances such as resin, bakelite, shellac, etc. have been proposed as binders for holding the wires together. But most of the time these binders are not able to withstand the stress on the piece when it is sawed. Instead, the individual wire particles splinter and the desired shape of the pieces is lost.



   According to the invention, this splintering can now be avoided by using the binder in connection with a fibrous material. This can be done in a number of ways. For example, the wires to be used can first be completely or partially spun with a fiber material and only then combined with one of the binders mentioned, or the fiber material can only be added before or during the construction of the piece intended for comminution. Of course, both measures can also be used at the same time.



   PATENT CLAIMS:
1. A method for producing magnetic cores for Pupin's coils, in which wires cemented to one another are arranged perpendicular to the magnetic flux as magnetic material, characterized in that fibrous materials are placed between the wires in addition to the known binders in order to increase the mechanical strength of the core.

The method according to claim l, characterized in that wires insulated with fiber material are cemented to one another with the aid of binders. 3. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass der Faserstoff vor oder während des Aufbaues des Kernes zugefügt wird. EMI1.3 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 3. The method according to claim 1, characterized in that the fiber material is added before or during the construction of the core.
