DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0024] The wire outlet nozzle arrangement 300 represented schematically in FIG. 1 includes a plurality of wire outlet nozzles 302 situated next to one another, from which corresponding winding wires 301 are fed in feed direction X. Also apparent is a first repositioning shaft 320, which rests on the wire outlet nozzles 302, the repositioning shaft 320 also including groove-like indentations, which positively attach to the outer contours of the wire outlet nozzles 302. A similar repositioning shaft 330 is similarly designed and abuts the nozzles 302 below the same. The repositioning shafts 320, 330 are henceforth also referred to as shafts for short. The shaft 320 is rotatably mounted about the axis P6 and in the present case is driven via a drive train, namely here via the gear 341, which is rotatable about a drive axis P5, and via the gear 342 coupled to the former, which is fixedly mounted on the shaft 320. The lower shaft 330 is rotatable about an axis P2. Here, too, there is a drive train 346, which is driven via a drive gear 345 which, in turn, is rotatable about the axis P1. However, this is merely one example for the drive of the two repositioning shafts 320, 330; the drive may also be achieved in completely different manner. The rotation of the two shafts 320, 330 about the axes P6, respectively, P2 is preferably synchronized.

[0025] In the example shown, the wire nozzle outlet arrangement according to the invention includes a substructure 370, in which the lower shaft 330 is rotatably mounted. This substructure 370 also serves as a base for supporting an upper part 350, which is mounted in the example shown on a carriage 355, which is mounted via the guides 360 so as to be movable in the direction P3 perpendicular to the feed direction X. The upper shaft 320 is rotatably mounted on the upper part about the axis 6. Thus, by moving the carriage 355 in the direction P3, the two shafts 320, 330 may in this way be moved relative to one another parallel to their axial direction. Moreover, the upper part 350 may be adjusted via a height adjustment 351 (in the example shown designed preferably as a lift cylinder) in direction P4 perpendicular to the direction P3 and perpendicular to the feed direction X. In this way, the two shafts 320, 330 may be displaced parallel relative to one another in direction P4.

[0026] Thus, with the mechanism depicted, the two shafts 320, 330 may be displaced relative to one another in the axial direction and perpendicular thereto. As a result, wire outlet nozzles 302 may be interchanged as is described below with reference to FIGS. 2-9.

[0027] In FIG. 2 depicts a specific arrangement of nozzles 302. For the sake of simplicity, these are numbered consecutively from left to right with 1-12. The two shafts 320 and 330 enclose the nozzle arrangement between them, wherein the nozzles 302 are situated next to one another in the sequence of 1-12 in corresponding grooves 321, 322, 323, respectively, 331, 332, 333 of the shafts 320, respectively, 330. The shafts 320, 330 include cams 325, respectively 335 situated in a comb-like manner, which are not shown in FIG. 2, because they are concealed in their rotational position by the shafts 320, 330. These are indicated in the sections in FIG. 3.

[0028] The shafts 320, 330as previously mentionedmay be rotated about their longitudinal axis. A quarter rotation yields the situation as it is depicted in FIGS. 4 and 5. The cams 325, respectively 335 now point toward one another and the shafts 320, 330 distance themselves from one another in direction P4. As is now apparent in FIG. 4, the even numbered nozzles 302 (2, 4, 6, 8, 10, 12) are situated between adjacent cams 325 of the upper shaft 320. Similarly, the odd numbered nozzles 302 (1, 3, 5, 7, 9, 11) are situated between adjacent cams 335 of the lower shaft 330. At the same time, the cams of the one shaft hold each of the opposite lying nozzles 302 between the cams of the respective other shaft. In this situation, which is shown in FIGS. 4 and 5, therefore, the even numbered nozzles are separated from the odd numbered nozzles and spaced apart from one another in direction P4, so that now they may be moved toward one another parallel to their axial direction by the relative movement of the two shafts.

[0029] FIGS. 6 and 7 show a situation in which, for example, the upper shaft 320 has been moved to the left relative to the lower shaft 330 in arrow direction P3, as opposed to the situation in FIG. 4. As a result of the comb-like cams 325, respectively, 335, the respective nozzles 302 are entrained, i.e. they follow this displacement movement. FIG. 6 shows a situation, in which the movement has taken place to the left by double the nozzle spacing in the direction of the arrow P3. The nozzles 2, 4, 6, 8, 10, 12 located on the upper shaft 320 are now situated again above exposed grooves of the lower shaft 330. If both shafts are then rotated, the cams disappear from the area between the shafts 320, 330 and the two shafts may again then be moved toward one another. This occurs preferably simultaneously, so that the nozzles 2, 4, 6, 8, 10, 12 associated with the upper shaft 320 may then be inserted again into the intermediate spaces between the nozzles 1, 3, 5, 7, 9, 11 on the lower shaft 330.

[0030] This results in the situation shown in FIGS. 8 and 9. As is apparent, the sequence of the nozzles relative to the starting situation in FIG. 2 has been interchanged by the process described; the sequence of nozzles is now 2, 1, 4, 3, 6, 5, 8, 7, 10, 9, 12, 11.

[0031] In this way, it is possible, for example, to implement a phase change by interchanging wires within a winding strand, which may be advantageous for the design of the wave winding and for the electromagnetic properties of the wave winding or of the symmetry of the components produced with the wave winding.
