   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

B. Papier) und zu beiden Seiten dieses letzteren je eine Schichte eines beim Schmelzen in der Hitze gut klebenden Isoliormittols (z. B. Schellack) gebracht und das Ganze nach dem Zusammenpressen erhitzt wird, dadurch gekennzeichnet, dass zwecks Verhinderung der Deformation im Betriebe die Spulen auch während ihrer Erhitzung einem in ihrer Achsenrichtung wirkenden hohen Drucke ausgesetzt werden. EMI2.1 Process for the production of field magnet coils from edgewise wound flat, bare copper strips for rapidly rotating magnetic wheels, in which a layer of an insulating material (e.g. paper) between the individual turns of the winding and on both sides of the latter a layer of one when melting in the Heat well-sticking isoliormittols (e.g. shellac) and the whole thing is heated after being pressed together, characterized in that in order to prevent deformation in operation, the coils are exposed to high pressure acting in their axial direction while they are being heated.
