PAUL nanscnnnnaon, or mnnu on-rnn-nnmn, Gramm assrenon m cannaan ELECTRIC oourm, a coaronnrron' or NEW roan.-
Application filed January 5, 1928. Serial No. 810,947.
To all whom it may concern Be it known that I, PAUL RAUsoHnNBAoH, a citizen of the German Realm, residing at Mehlem-on-the-Rhine, Germany, have 1nvented certain new and useful Improvements in Methods and Means for Winding Annular Bodies, of which the following is a specification. 7
In the machines for winding annular bodies heretofore known, the wire material used was taken from a supply-ring or wind ing-ring, which was rotated radially to the body to be wound. This arrangement had the disadvantage that each time, after the annular body to be wound was inserted in the winding or supply-ring (which was adapted to open out), the necessary wire material .had first to be wound on the supply ring before being used. This operation was repeated at every new beginning of the process. A second solution, now in practice, is better than the former this. solution consisting in substituting for the supply or winding-ring a carrier-ring on which is placed a coil containing the necessary wire material. By this method it is only necessary to exchange the coil for each new operation, and in this way a more rapid sequence in the winding process may be obtained. This method also has one disad'vantage, namely, a lack of ready accessibility to the point where the work is being done, and a restriction in the size of the coil for a given diameter of the annular body and therefore a restriction to a small quantity of wire.
By the present invention the above disadvantages are avoided. In addition to ready accessibility of the region where the operation is being efi'ected, and the greatest possible utilization of the available space, the machine affords the possibility of replacing very rapidly the material used.
In the accompanying drawing, Fig. 1 shows in diagrammatic form one illustrative construction of my invention, while Fig. 2 is a plan view of the feeding mechanism. In the embodiment of the invention shown, the material, which may be an electrically conducting wire, is first wound helically, then put into a two-part winding-rim of tubular cross-section, and then passed a out sections so that it maybe passed through the ring that is to be wound so as to interlink therewith. The winding material is first wound helically, then the helix 0 of wire thus formed is put into the open windingring, one end of the wire being passed between the two guide-rollers d and a? (Fig. 2) and out of the opening e on the inner side of the winding-ring. The guide-rollers d and d are to advantage located on the plug or closing device f, which has two projections engaging in the two halves of the ring. On the plugf is placed, in addition to the two guide-rollers, a guide spindle or tongue g which is slightly curved to conform to the windin -ring, and which extends into the wire he ix 0. The purpose of this tongue 9 is to prevent distortion of the wire on being drawn out. In the process ofwindin by reason of the tongue the turns of the helix 0 cannot be simp yradjusted, but the entire helix must rotate about its longitudinal axis in the winding-ring. the fact that the wire must first be passed about the guide spindle and then passed between the two gu1de-rollers d and d, there is a slight braking effect, which allows the wire to be drawn out easily without injuring the insulation, but which also prevents the wire from rolling up automatically, and therefore there is a sufiicient tension. Also it is immaterial whether the windin -wire is brought into the winding-ring in't e'form of a right-hand or left-hand-wound helix, since the exit opening for the wire is in the center, and the wire therefore places-itself against one or the other guide-roller d or (1, according as it is drawn about the guidespindle from one side or the other. No special device is necessary for keeping the wire tense so long as the central point of the winding-ring a lies in the cross-section to be wound. In this case the winding material is drawn off from the ring in all positions of the ring.
The winding-ring may, as shown in the drawing, be driven by friction rollers. On the machine frame It is mounted the swinging arm 21 which carries the actuating roller is. Moreover, the winding-ring or also lies between the two guide-rollers Z and m. Instead of a friction gearing of course a gearwheel drive may be used. In this case the winding-ring a would be provided with a toothed rim in which would engage a By reason of I toothed wheel instead of the friction-wheel 7c. The friction gearing however involves the great advantage that the winding-ring can be kept perfectly smooth outside, an
thus there is no possibility of harm to the insulation of the wire wound on the body in question. m
The process above described and the-device employed therefor are particularly adapted for such wires as are provided with a delicate insulation, for example, wires having a silk covering. By reason of the fact that the winding material is arranged in an entirely closed winding-ring, and by reason of the special employment of a guidespindle, it is impossible for the wire helix to become distorted so that in ury to the insulation is virtually impossible.
What I claim as new and desire to secure by Letters Patent of the United States, is,-
1. The method of winding annular bodies which consists in winding the material in the form of a helix, slipping the helix into a two-part winding-ring of tubular cross-.
section, and then leading the material to the body to be wound through an opening on the inner side of the winding ring, whereby the helix is rotated about its longitudinal ans.
2. Means for winding annular bodies comprising a tubular ring divided into sections so that it may be interlinked with the body to be wound, winding material wound into a helix and sli ped mto said ring, a guide spindle exten ing into said helix, a pair of guide rollers'for said material, and means for rotating said ring so as to wind said material on said body.
3. Means for winding annular bodies comprising a tubular winding ring divided into sections so that it may be interlinked with the body to be wound, winding material wound into a helix and slipped into said ring, a closing device at the joint between V the sections of said ring, a guide pin on said closing device extending into said helix, a pair of guide rollers on said device for said material, and means for rotating said ring so as to'wind said material on said body, whereby said helix is caused to rotate about its axis.
In witness whereof I have hereunto set no hand this 15th day of December 1922.
