   Gruppen   derart   anzuordnen,   dass die Länge der einzelnen Schenkel verringert wird. Durch die kleinere Länge der   einzelnen   Elemente wird erreicht, dass eine geringere Form- und Lage-   veränderung   derselben durch die Wärme hervorgerufen und dadurch die Gefahr eines Kurz-   schlus'es durch Berührung   der Nachbarschenkel infolge der   Ausdehnung   beseitigt wird. Wie aus Fig. 5 der Zeichnung ersichtlich ist, ist der Leiter z. B. in zwei Gruppen angeordnet, von'denen jede eine halbe Kreisfläche einnimmt.

   Hiedurch wird die Länge jedes einzelnen Schenkels auf die Hälfte   herabgemindert.   Diese Gruppen können sowohl parallel als auch hintereinander ge-   schaltet sein.   



   PATENT. ANSPRÜCHE : 
1. Verfahren zut Herstellung eines in schlangen- bezw. Zickzachlinien verlaufenden elektrischen Widerstandes mit flachem Querschnitt, dadurch   gekennzeichnet, dass entweder   ein Flachdraht hochkantig gebogen und die an der Innenseite der Biegungen sich gegebenenfalls ergebenden Materialverdickungen durch Pressen verflacht werden oder aber ein Draht von

 EMI2.1
   Arrange groups in such a way that the length of the individual legs is reduced. The smaller length of the individual elements ensures that the heat causes less change in shape and position of the same, thereby eliminating the risk of a short circuit through touching the neighboring legs as a result of the expansion. As can be seen from Fig. 5 of the drawing, the conductor is z. B. arranged in two groups, each of which takes up half a circular area.

   This reduces the length of each individual leg by half. These groups can be connected in parallel or one behind the other.



   PATENT. EXPECTATIONS :
1. Process for the production of a snake or. Zigzag lines running electrical resistance with a flat cross-section, characterized in that either a flat wire is bent on edge and the material thickenings that may arise on the inside of the bends are flattened by pressing or a wire from

Claims (1)

nach erfolgter Flachpressung des Drahtes infolge der in den Bogenstücken enthaltenen Spannung parallel legen. After the wire has been pressed flat, lay it in parallel due to the tension contained in the curved pieces. 3. Vorrichtung zur Ausführung des Verfahrens nach Anspruch 2, dadurch gekennzeichnet, dass in einer Platte (8, 9) je nach den herzustellenden Windungen angeordnete Stifte (11) in Locher (10) passend eingesetzt oder federnd angeordnet sind, welche beim folgenden Pressen des um dieselben gewundenen Drahtes tiefer in die Löcher eindringen. 3. Apparatus for carrying out the method according to claim 2, characterized in that in a plate (8, 9) depending on the turns to be produced, pins (11) are appropriately inserted or resiliently inserted into holes (10), which during the subsequent pressing of the penetrate deeper into the holes by the same twisted wire.
