The present invention relates to a device for orthocyclic winding of wire with a cylindrical bobbin, which is shallow between two flanges on its circumferential surface Has grooves with at least the wire diameter the same groove center distance.

It has hitherto been considered necessary in the known devices of this type, in the case of successive Winding layers unavoidable crossing points between the superimposed Concentrate turns on certain circumferential sections of the bobbin. This is how they go Grooves of the bobbin according to British patent specification 819 273 over about two thirds of its circumferential surface in planes perpendicular to the center axis of the winding body, while they are in the remaining third of the circumference are inclined to these planes so that each groove merges into the groove adjacent to it. Through this are the transition points of all winding layers in the same circumferential area, and the wound The coil is noticeably thicker in this area than the rest. The result is an imbalance that occurs at rapid Unwinding the wire can be extremely uncomfortable.

To compensate for the overlapping and the resulting thickening of the coil to achieve the resulting imbalance has been suggested in the German interpretation document 1046 715, to form a winding body from two diametrically opposed groups of slots, which each extend over about a third of the body circumference and around half a wire diameter are axially offset from one another, while the remaining third of the circumference of two opposite one another Flattening is taken. Two opposing turns are created on these for each wire turn Transition points at which the wire is cut laterally by half a wire diameter is moved. When winding, two diametrically opposed bobbin thickenings are formed, which, in a first approximation, should bring about an unbalance compensation. For an even Incidentally, spooling requires special control strips on the flanges of the bobbin so that the winding device according to the German Auslegeschrift 1046 715 not for a fast, automatic Winding of small coils is suitable. This is also expressed in the fact that the device is on a cable drum is limited, so on the large diameter cables are wound.

In contrast, the object of the invention is to avoid the disadvantages of the known devices Device for orthocyclic winding

of wire with a cylindrical bobbin

and to create a simply constructed and inexpensive to manufacture device, with the not only high Winding speeds, but also an even, practically unbalance-free winding without the Formation of thickenings in certain circumferential areas are possible, so that the winding is automatic can be done.

This object is achieved according to the invention in a device of the type mentioned at the beginning achieved in that all the grooves over their entire circumference in a direction perpendicular to the center axis of the winding body Planes run and that one of the two edge grooves adjacent to the flanges with her Groove center in a known manner by half, the other by a whole wire diameter from respective flange is removed.

In this way, a completely rotationally symmetrical winding body is created, which as a result of its extremely simple construction can be produced with minimal effort and at the same time a flawless one Orthocyclic winding is permitted with a high winding speed that can be used from the start. Against it In the known devices, the winding body is not rotationally symmetrical, but rather unbalanced in the execution according to British patent specification 819 273 and asymmetrical in the execution according to of the German Auslegeschrift 1 046 715 mirror symmetry, which leads to the mentioned one-sided and two-sided Leads to thickening of the wound coil.

increases and, in addition, the area of use as shown in FIG. 2, there is a coil 6 extended to very small coils. Moreover, it results from a flange XO on both sides a more even distribution of the wire on the 30 or 11 limited hub-shaped part 9. In this Winding body, so that with given dimensions hub-shaped part 9 is a series of shallow grooves Larger wire lengths can be wound up or 12 are provided, each with the same center distance for a given wire length Heinere winding bodies are sufficient up to the middle of each other in a perpendicular to the middle, axis 13 of the coil standing plane.

In the winding body according to the invention, the grooves adjoining the flanges 10 and 11 are found

exiting wire the position of the second turn right end of the hub-shaped part 9 of the coil 6

has been reached and the so-called base position has been laid. A further rotation of the coil 6 arises as a result the beginning of a second winding layer, as can be seen from FIG.

From Fig. 3 the fastening of the wire end in the coil 6 can be clearly seen. In contrast to the usual fastening, the fastening opening 14 is now directed in such a way that its central axis intersects the central axis of the coil 13 or crosses it close to it. It is possible to provide this opening 14 in such a way that the same is not provided in a plane perpendicular to the central axis 13 (as shown in FIG. 2), but in an inclined plane, so that the opening extends obliquely through the in Fig. 2 left flange extending hole.

The latter option is important if a full hub is used as a spool. Most of the time you will however, use a plastic, openwork coil with a hollow hub, as shown in the Fig. 2 and 3 is shown, in which case preferably an opening 14 directed perpendicular to the central axis 13 of the coil is used.

This design has the advantage that with a wound coil there is no protruding beginning of the Wire is available.

If you want to make coils of wire without placing the windings on a final reel the wire can be wound onto a sleeve pushed onto the mandrel 4, which, after being removed from the mandrel, disassembles in a manner known in the art can be.

Finally, it should be noted that the cylindrical coil, as shown in FIG. 2 shown in a simple manner can be created and adapted to the type of wire to be wound. This is achieved in that one with a profiled chisel during the rotation of the spool radially between the flanges 10 and penetrates, the chisel profile being precisely adapted to the size and position of the grooves 12 to be made is. At the same time you achieve with this profiled chisel that the distance between the inner sides of the flanges 10 and 11 is exactly made to measure.
