DETAILED DESCRIPTION
(7) FIG. 1 is a cross-sectional view of a wire 10. The wire 10 has a first portion 12, a second portion 14 and a third portion 16. The third portion 16 connects the first portion 12 and the second portion 14. In the third portion 16, the wire has a reduced cross-section. The first portion 12 and the second portion 14 have a larger cross-section compared with the third portion 16. The first portion 12 and the second portion 14, when viewed in cross-section, are substantially round. The third portion 16 extends in the form of a connecting web between the first portion 12 and the second portion 14.
(8) The wire 10 has a curved shell surface MF. The shell surface MF is curved in the third portion 16 in the opposite direction to its curve in the first portion 12 and in the second portion 14. The shell surface MF is curved concavely in part in the third portion 16. In the first portion 12 and in the second portion 14, the shell surface MF is curved convexly in part.
(9) When viewed in an xy-coordinate system, the cross-section of the wire 10 changes along its extent in the x-direction. Starting from the starting point 12.sub.1 on the shell surface MF of the wire 10, the cross-section of the wire 10 increases, curved in the y-direction, to the apexes 12.sub.2 and 12.sub.3. Between the apexes 12.sub.2 and 12.sub.3, the first portion 12 of the wire 10 has its largest cross-section, or its greatest extent in the y-direction. Starting from the apexes 12.sub.2 and 12.sub.3, the cross-section of the wire 10 in the first portion 12 decreases, curved in the direction towards the third portion 16. In the third portion 16, the wire 10 has its smallest cross-section in the y-direction. Since the shell surface MF of the wire 10 also extends in a curved manner in the third portion 16, the wire 10 has its smallest cross-section in the y-direction in the third portion 16 between the apexes 16.sub.1 and 16.sub.2. Starting from the apexes 16.sub.1 and 16.sub.2, the cross-section of the wire 10 increases in the second portion 14 again in a curved manner to the apexes 14.sub.1 and 14.sub.2 of the curve of the second portion 14. Between the apexes 14.sub.1 and 14.sub.2 of the curve of the shell surface MF in the second portion 14, the wire 10 has its largest cross-section in the y-direction in the second portion 14. Starting with the apexes 14.sub.1 and 14.sub.2, the cross-section of the wire 10 decreases in the y-direction in the third portion 14 in a curved manner to the end point 14.sub.3.
(10) The third portion 16 is arranged between the first portion 12 and the second portion 14. The third portion 16 lies on an imaginary straight line through the starting point 12.sub.1 and the end point 14.sub.3, which is shown as a broken line in FIG. 1.
(11) The above description of the cross-section of the wire 10 can be summarized as follows. Between the apexes 12.sub.2, 12.sub.3 and 14.sub.1, 14.sub.2 of the curves of the shell surface MF in portions 12 and 14, the wire 10 in each case has an indentation EW.sub.1 and EW.sub.2, which reduce the cross-section of the wire 10 in the third portion 16. The indentations EW.sub.1 and EW.sub.2 extend towards one another in the y-direction and reduce the cross-section of the wire 10 in the third portion 16. As a result, the wire 10 has its smallest cross-section in the y-direction in the third portion 16.
(12) FIG. 2 shows a stranded wire 100. The stranded wire 100 has three of the wires shown in FIG. 1, which are denoted 10.sub.1, 10.sub.2 and 10.sub.3. The stranded wire 100 has an inlay element 18, which forms the midpoint of the stranded wire 100. The inlay element 18 has a round cross-section. The wires 10.sub.1, 10.sub.2 and 10.sub.3 are arranged around the inlay element 18 and each lie with their first portion 12 and their second portion 14 against the inlay element 18 in places. The wires 10.sub.1, 10.sub.2 and 10.sub.3 lie on a radius R around the midpoint of the stranded wire 100, that is to say on a radius R around the inlay element 18.
(13) The wires 10.sub.1, 10.sub.2 and 10.sub.3 touch one another at the points of contact BS.sub.1, BS.sub.2 and BS.sub.3. The second portion 14 of the wire 10.sub.1 lies against the first portion 12 of the second wire 10.sub.2 at the point of contact BS.sub.1. The second portion 14 of the wire 10.sub.2 touches the first portion 12 of the wire 10.sub.3 at the point of contact BS.sub.2. The second portion 14 of the wire 10.sub.3 contacts the first portion 12 of the wire 10.sub.1 at the point of contact BS.sub.3. The points of contact BS.sub.1, BS.sub.2 and BS.sub.3 between the wires 10.sub.1, 10.sub.2 and 10.sub.3 lie on the radius R around the inlay element 18 which forms the midpoint of the stranded wire 100.
(14) In the following, for reasons of clarity, only some points of contact are marked in the figures. For figures in which radii are depicted, it is to be assumed that points of contact lie on those radii, even if the points of contact are not shown in the corresponding figures.
(15) FIG. 3 shows a stranded wire 110. The stranded wire 110 has multiple inlay elements 18, 20, 22, 24, 26, 28, 30. The stranded wire 110 has six wires 10.sub.1 to 10.sub.6.

The wires 10.sub.1, 10.sub.3, 10.sub.4, 10.sub.6, 10.sub.7 and 10.sub.9 lie with their second portion 14 against the inlay element 18. The second portions 14 of the mentioned wires lie on the first radius R.sub.1. The wires 10.sub.2, 10.sub.5 and 10.sub.8 are arranged on the second radius R.sub.2. The wires 10.sub.2, 10.sub.5 and 10.sub.8 are arranged between the wires 10.sub.1, 10.sub.9 and 10.sub.3, 10.sub.4 and 10.sub.6, 10.sub.7 extending in pairs. The wires 10.sub.1 to 10.sub.9 are arranged in such a manner that they support one another and are thus able to maintain their predetermined position and/or location.
(38) FIG. 18 shows a stranded wire 240. The stranded wire 240 is of a similar structure to the stranded wire 230. In addition to the structure of the stranded wire 230 shown in FIG. 17, the stranded wire 240 also has the wires 10.sub.10 to 10.sub.18 arranged on the third radius R.sub.3.
(39) FIG. 19 shows a stranded wire 250. The stranded wire 250 has a hexagonal cross-section. The wires 10.sub.1 to 10.sub.9 are arranged against the inlay element 18 in such a manner that a hexagonal cross-section is obtained. The wires 10.sub.1, 10.sub.2 and 10.sub.3 lie with their two portions 12 and 14 against the shell surface of the inlay element 18 which forms the midpoint of the stranded wire 250. The wires 10.sub.4 to 10.sub.9 are arranged in such a manner that a first portion 12 of those wires in each case contacts a first portion 12 and a portion 14 of the wires 10.sub.1, 10.sub.2 and 10.sub.3, wherein the portions 12 and 14 do not always have to belong to a single wire 10.sub.1 to 10.sub.3.
(40) The wires 10.sub.1, 10.sub.2 and 10.sub.3 which touch the inlay element 18 also touch one another at the points of contact BS.sub.1. The points of contact BS.sub.1 lie on a common radius R. The wires 10.sub.4 to 10.sub.9 also touch one another at the points of contact BS.sub.2, wherein in each case a first portion 12 contacts a second portion 14. Owing to the hexagonal arrangement of the wires 10.sub.4 to 10.sub.9, the points of contact BS.sub.2 do not lie on a common radius.
(41) FIG. 20 is a cross-sectional view of a stranded wire 260. The stranded wire 260 has a similar structure to the stranded wire 250 which has been described with reference to FIG. 19. Compared with the stranded wire 250, the stranded wire 260 has additional wires 10.sub.10 to 10.sub.18, which are arranged along the wires 10.sub.4 to 10.sub.9. In respect of the wires 10.sub.10 to 10.sub.18, the portions 12 and 14 of each of the wires 10.sub.10 to 10.sub.18 together contact a first portion 12 or a second portion 14 of the wires 10.sub.4 to 10.sub.9, wherein the portions 12 and 14 do not always have to belong to a single wire 10.sub.4 to 10.sub.9, that is to say they can also be the first portion 12 and the second portion 14 of two wires 10.sub.4 to 10.sub.9.
(42) FIGS. 21 to 23 show drawing dies 300, 302, 304 which can serve to produce the wire 10 shown in FIG. 1. The drawing die 300 has a round opening 306 in order to draw a wire into a form with a round cross-section.
(43) The drawing die 302 according to FIG. 22 has a slot-shaped opening 308. By means of the slot-shaped opening 308, the wire acquires a cross-section that is oval in the broadest sense or also rod-shaped.
(44) The drawing die 304 brings the wire into the shape shown in FIG. 1. For that purpose, the drawing die 304 has an opening 310. A wire having the cross-section produced by the drawing die 302, for example, can be drawn through the opening s 310 of the drawing die 304 (see FIG. 22). The opening 310 has two substantially round portions 312 and 314 which are separated from one another by two projections 316 and 318. The projections 316, 318 protrude into the opening 310 and face one another. By means of the projections 316 and 318, the cross-section of the opening 310 is reduced in that region, that it so say the cross-section of the wire in the third portion 16 (see FIG. 1) is reduced by the projections 316 and 318.
(45) The wires 10 shown in FIG. 1 can be arranged in such a manner that they retain their predetermined position and/or location during production or during the stranding process. This means that the wires 10 are arranged in a predetermined position and/or location and are able to maintain that position and/or location during the production process. During the stranding process, all the wires 10 in a cable assembly twist, and the individual wires 10 cannot move because of their cross-section. With the wires 10 it is possible to produce a stranded wire with a round cross-section and also a circular cross-section, as is shown, for example, in FIG. 3 to 18. Owing to the round cross-sections of the stranded wire which are possible with the wire 10, insulating material can be saved, so that the production costs for a stranded wire are also reduced.
(46) Furthermore, as is shown in FIGS. 19 and 20, stranded wires with a hexagonal cross-section can also be produced. Stranded wires with an irregular structure, which have inlay elements in only some part-regions, can also be produced with the wire 10 shown in FIG. 1, without a constricted assembly forming or the cross-section of the stranded wire becoming increasingly constricted.
(47) With the drawing die shown in FIG. 23 it is possible to draw a wire 10 which, in a stranded wire, occupies the space of two conventional wires 10 with a round cross-section. The production time for the wire 10 can thereby be reduced and capacity at the production facility can be saved. In the case of aluminum wires, the transverse conductivity of the stranded wire is improved since no contact resistances occur between the wires 10 with the above-described cross-section.
