KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Für manche Zwecke, wie sie zum Teil auch bei der Herstellung von elektrischen Meßinstrumenten in Betracht kommen, ist es vorteilhaft, eine Stromspule anzuwenden, welche aus einem hochkant gewundenen Metallstreifen erhalten ist. Doch bietet die Anfertigung derartiger Spulen, zumal wenn die zu verwendenden Metallstreifen von geringer Dicke sind, ziemliche Schwierigkeit.For some purposes, such as those used in the manufacture of electrical measuring instruments come into consideration, it is advantageous to use a current coil, which consists of an edgewise wound metal strip is preserved. But the production of such coils offers, especially if the Metal strips of small thickness to be used are quite difficult.
ίο Bei Anwendung des im folgenden beschriebenen Verfahrens gelingt es jedoch leicht, derartige Spulen aus einem zusammenhängenden Blechstück lediglich durch Umbiegen herzustellen:ίο When using the one described below However, it is easy to produce such coils from a coherent process To produce a piece of sheet metal simply by bending it over:
Man schneidet oder stanzt aus einem längeren Blechstreifen die in Fig. 1 gezeichnete mäanderförmige Figur aus und klappt jetzt längs der Linien α von unten nach oben und längs der Linien b von oben nach unten um, wodurch ohne weiteres die gewünschte Spulenform erhalten wird.The meander-shaped figure shown in FIG. 1 is cut or punched from a longer sheet metal strip and now folds along the lines α from bottom to top and along lines b from top to bottom, whereby the desired coil shape is easily obtained.
Auch aus der etwas komplizierteren Fig. 2 läßt sich dieselbe Spule herstellen, indem man bei α von oben nach unten und bei b von rechts nach links, umklappt.The same coil can also be produced from the somewhat more complicated FIG. 2 by folding over from top to bottom at α and from right to left at b.
Fig. 3 zeigt die Form des Metallbandes, welche eine Spule von kreisförmiger Windungsfläche liefert, wenn man bei α nach oben und bei b nach unten umklappt.Fig. 3 shows the shape of the metal strip which provides a coil with a circular winding surface when folded upwards at α and downwards at b.
Natürlich kann auch in allen diesen Fällen den einzelnen Windungen eine verschieden große Windungsfläche gegeben werden, so daß ζ. B. unter Anwendung der in Fig. 3 gezeichneten Metallbandform ohne Schwierigkeit eine Spule mit kugel- oder ellipsoidförmigem Hohlraum herstellbar ist.Of course, the individual turns can also be different in all of these cases large winding area can be given, so that ζ. B. using the in Fig. 3 drawn metal strip shape without difficulty a coil with spherical or ellipsoidal Cavity can be produced.
