Magneträder.

empfindliche Störung.
Diese Nachteile werden durch die gemäss vorliegender Erfindung hergestellten Spun'n behoben.
Beim neuen Verfahren kommt es darauf an, dass, nachdem zwischen die einzelnen Windungen der Wicklung je eine Lage Papier (oder ein anderer geeigneter Isolierstoff) und zu beiden Seiten desselben je eine Schichte eines in der Hitze schmelzbaren und gut lilebenden Isoliermittels (z. B. Schellack) gebracht worden ist, die Spulen einem während ihrer Erhitzung über die Schmelztemperatur des isolierenden Klebmittels aufrechterhaltenen in der Achsenrichtung der Spulen wirkenden hohen Drucke ausgesetzt werden. Dieser

Der hohe Druck kann zweckmässigerweise entweder durch eine hydraulische Presse oder durch Schrauben ausgeübt werden.
Da während des Schmelzens des isolierenden Klebemittels oin Teil desselben zwischen den Windungen seitlich austritt und der Druck nachgiebt, so müssen während des Er-

Wenn das Klebemittel unter diesem konstanten hohen Drucke erstarrt ist, so sind die einzelnen Gänge der aus hochkant gewickeltem, flachem Kupferbande hergestellten Spule miteinander äusserst fest verbunden, so dass die Spule einen massivf-n Zylinder bildet, welcher auf die Magnetschenkeln aufgeschoben und durflt die Polschuhe in seiner Stellung gesichert, unter dem hohen Drucke und der Erwärmung, denen die Spulen beim

sensitive disorder.
These disadvantages are eliminated by the spun produced according to the present invention.
With the new method, it is important that after a layer of paper (or another suitable insulating material) between the individual turns of the winding and a layer of a heat-fusible and well-living insulating material (e.g. Shellac), the coils are subjected to high pressures in the axial direction of the coils while they are being heated above the melting temperature of the insulating adhesive. This

The high pressure can expediently be exerted either by a hydraulic press or by screws.
Since during the melting of the insulating adhesive part of the same emerges laterally between the windings and the pressure yields, so during the

When the adhesive has solidified under this constant high pressure, the individual turns of the coil made of upright wound, flat copper tape are extremely tightly connected to one another, so that the coil forms a solid cylinder which is pushed onto the magnetic legs and passes through the pole shoes secured in its position, under the high pressures and warming that the coils experience
