Description

\ N V E N T O R:
H t f u Dec. 10, 1929. J MAJCE METHOD OF MANUFACTURING WIRE COILS Filed Nov. 7, 1927 Patented Dec. 10, 1929 UNITED STATES J'OHANN MAJ'OE, OF VIENNA, AUSTRIA METHOD OF MANUFACTURING WIRE COILS Application filed. November 7, 1927, Serial No. 281,446, and in Austria November 10, 1926.
Wire coils for electro-technical purposes the windings of which are wound on rods of insulating material have been hitherto manufactured by cutting channels or the like in the rods for holding the individual convolutions and by laying the wires, during winding, in the channels. The making of the channels and the winding or coiling, which call for great precision and care, involve great loss of time.
The present invention consists of a method of manufacturing such coils, in which the cutting of the channels or the making of recesses or the like in the rods of insulating material is entirely eliminated, as the wire convolutions are laid onto smooth rods, but are nevertheless immovably mounted thereon. The present method is therefore much simpler and more rapid and permits a considerably greater saving intime and labour in the production of the coils than has hitherto been possible.
The invention is illustrated b way of example in the accompanying rawings, in wh1ch Fig. 1 is a perspective View of a coil made indaccordance w1th the present invention; an
Figs. 2 and 3 are vertical sectional views illustrating the appearance of the coil at different stages in its manufacture.
The wire convolutions a of the coilshown in Fig. l are wound onto smooth rods 1) of insulatin material in the usual manner. During t e winding the rods are softened, preferably by heatin the wire convolutions y sending an electric current through the same. In consequence of the heating of the wire convolutions the material of the rods b on the surface, i. e., under the convolutions, becomes soft and the convolutions form channels in the rods, in which they become automatically embedded (Fig. 2).
If desired the upper side of the rods can also be smoothed by means of hot elements. The material between the wire convolutions becomes softened and 8 read over the wires in such a manner that t e latter are covered completely by the material of the rod at the points where they lie, the upper surface becoming smooth and the coilassuming the appearance shown in Figs. 1 and 3. I
The method can be applied with all rods composed of insulating material used for such coils and can also be carried out by softening the rods carrying the windings in any desired manner.
What I claim is 1. The method of manufacturin wire coils which consists in supporting a p urality of rods of readily fusible insulating material in spaced relation to each other, and winding 3. length of wire in heated condition in contact with one side of each of saidrods, thereby to melt the material of the rods at the points of contact with the wire and cause said wire to embed itself in the rods.
2. The method of manufacturin wire coils which consists in supporting a p urality of rods of readily fusible insulating material in spaced opposin relation to, each other, winding a length 0 wire around said rods in contact with one side thereof, and simultaneously passing an electric current through said wire to heat the same and melt said rods at their intersections with said wire thereby to cause the wire to embed itself in the rods.
3. The method of manufacturing wire coils which consists in supporting a plurality of rods of readily fusible insulating material in spaced opposing relation to each other, winding a length of wire under tension around said rods in contact with one side of each, and simultaneously passing an electric current through said wire to heat the same and melt said rods at their intersections with said wire thereb to cause the wire to embed itself in the r0 s, and smoothing the material of said rods over the wire embedded therein.
In testimony whereof I have afiixed my signature.
