KAISERLICHESIMPERIAL

PATENTAMT,PATENT OFFICE,

Das Verfahren besteht darin, daß eine oder mehrere Lagen aus Draht beliebigen Materials und beliebigen, vorzugsweise runden Quer-. Schnitts, welcher frei oder auf metallische 5 oder isolierende Schablonen, Rahmen u. dgl. gewickelt ist, in einer den Umrissen der anzufertigenden Spule angepaßten Preßvorrichtung in eine solche Form gedrückt werden, bei der sich die einzelnen Windungen ohneThe method consists in making one or more layers of wire of any material and any, preferably round, transverse. Cut, whichever is free or on metallic 5 or insulating stencils, frames and the like. Wrapped in one of the outlines of the Coil adapted pressing device are pressed into such a shape, in which the individual turns without

ίο raumvergeudende Luftzwischenräume auf das innigste aneinander schmiegen, und bei welcher die Spule infolgedessen eine geringere Höhe in Richtung des ausgeübten Druckes annimmt. Man kann die Spule beim Pressen in den zum Druck senkrechten Richtungen zur tunlichsten Verringerung ihrer Höhe sich entsprechend verbreitern und verlängern lassen, oder diese Formänderung durch geeignete Gestaltung der Preßform beim Pressen ganz oder teilweise ausschließen. Ebenso kann die Spule sowohl an ihrem ganzen Umfange, wie auch nur in einer oder mehreren bestimmten Richtungen gepreßt werden, so daß also der Querschnitt des zur Wicklung verwendeten Drahtes an den ungepreßten Stellen ungeändert bleibt. Durch das Drücken in der polierten Preßform erhält man zudem eine spiegelglatte, faser- und lückenlose Oberfläche , an der weder Staub noch Fasern haften können. Das Verfahren eignet sich daher in ganz besonderem Maße zur Herstellung von Drehspulen für elektrische Meßinstrumente mit engem permanenten Magnetfeld. ίο space-wasting air gaps on the most intimately nestle against each other, and in which the coil is consequently a smaller one Assumes height in the direction of the pressure exerted. You can press the bobbin in the directions perpendicular to the pressure to reduce their height as much as possible widening and lengthening accordingly, or this change in shape by means of suitable ones Completely or partially exclude the design of the mold during pressing. Likewise can the coil both in its entire circumference, as well as only in one or more specific areas Directions are pressed, so that the cross-section of the used for winding Wire remains unchanged at the uncompressed points. Pressing in the polished die also gives a mirror-smooth, fiber-free and gap-free surface, on which neither dust nor fibers can stick. The method is therefore particularly suitable for production of moving coils for electrical measuring instruments with a tight permanent magnetic field.

In beifolgenden Fig. la, 1 b, 2a und 2b sind rechtwinklig zur Längsrichtung der Windungen geführte Schnitte durchIn the attached Fig. La, 1b, 2a and 2b are cuts made at right angles to the longitudinal direction of the windings

1. eine in einer Lage auf einen Rahmen gewickelte Spule,1. a coil wound in one layer on a frame,

2. eine in zwei Lagen auf einen Rahmen gewickelte Spule dargestellt, und zwar a) in ungepreßtem Zustande der Spule, b) in gepreßtem Zustande der Spule.2. a coil wound in two layers on a frame is shown, namely a) in in the unpressed state of the bobbin, b) in the pressed state of the bobbin.

Muß der Draht aus bestimmten Gründen auf einen metallischen oder isolierenden Rahmen gewickelt werden, so kann man es durch die Wahl eines relativ weichen Materials hierzu erreichen, daß die einzelnen Windungen infolge des ausgeübten Druckes in diesen Rahmen eingebettet werden, wie Fig. ib und 2b zeigen. Dadurch wird eine weitere Raumersparnis in der Druckrichtung und eine größere Stabilität der ganzen Spule erzielt, sobald es sich um Spulen von geringem oder flachem Querschnitt handelt. In den Fig. 1 b und 2 b ist gleichzeitig die oben erwähnte, senkrecht zum Druck erfolgte Verbreiterung der Spule dargestellt.For certain reasons the wire has to be made of metal or insulating material Frame can be wrapped so one can do it by choosing a relatively soft material achieve this that the individual turns as a result of the pressure exerted embedded in this frame, as Fig. 1b and 2b show. This creates a further space saving in the printing direction and greater stability of the entire spool achieved as soon as the coils are of small or flat cross-section. In Figs. 1b and 2b, the above-mentioned is carried out perpendicular to the print at the same time Broadening of the coil shown.

Das Verfahren gestattet also die Unterbringung derartig gepreßter Spulen in einem Räume, welcher für. die Aufnahme der ungepreßten Spulen zu klein bemessen wäre. Es gestattet insbesondere bei gegebener Windungszahl die Verwendung von Draht größeren Querschnitts, also geringeren Wider-Standes, als dies ohne Pressung zur Unterbringung der Spule in einem gegebenen Räume möglich wäre. Man kann daherThe method thus allows such pressed coils to be accommodated in one Rooms, which for. the inclusion of the uncompressed bobbins would be dimensioned too small. It allows the use of larger wire, especially with a given number of turns Cross-section, so less resistance than this without compression for accommodation the coil in a given space would be possible. One can therefore

Draht aus Material von geringem spezifischen Gewichte entweder zwecks Erleichterung der Spulenwicklung bei gegebenem elektrischen" Widerstand und gegebener Windungszahl 5 oder zwecks Verringerung des elektrischen Widerstandes bei gegebener Windungszahl und gegebenem Gewicht der Spulenwicklung mit Vorteil verwenden.Wire made of material of low specific gravity either for the purpose of facilitating the Coil winding for a given electrical resistance and a given number of turns 5 or for the purpose of reducing the electrical resistance for a given number of turns and given weight of the coil winding to advantage.

Endlich gestattet das Verfahren die Unterbringung einer bedeutend größeren Windungszahl bei gegebenem Drahtquerschnitt auf einer in einem gegebenen Räume unterzubringenden Spule.Finally, the method allows a significantly larger number of turns to be accommodated for a given wire cross-section on one to be accommodated in a given room Kitchen sink.
