[0019] The invention is explained in greater detail below with reference to the FIGS. 1-3.

[0021] FIG. 2 shows a sectional view through a wire outlet nozzle arrangement in a first position, and

[0022] FIG. 3 shows a sectional view through a wire outlet nozzle arrangement in a second position.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0023] The wire outlet nozzle arrangement 200 shown in FIG. 1 includes a plurality of wire outlet nozzles 202, through which wires 201 are guided from the device 200 in a feed direction X and are guided, for example, to a shaping core of a wave winding device not shown, where the wires 201 are then wound to form a wave winding.

[0024] The arrangement 200 shown further includes a first contour roller 220 and an optional second contour roller 230 situated downstream thereof in feed direction X. It is sufficient for the functionality of the invention if the arrangement 200 includes a total of merely one contour roller. To synchronize the nozzles, the embodiment shown requires the use of two contour rollers 200, 230 spaced apart from one another, so that during a movement of the nozzles 202 relative to one another in the arrow direction P1, P2, the nozzles do not tip and assume an angle relative to feed direction X. Suitable other guide mechanisms that achieve the same may also be used. The contour roller 220 is rotatable about an axis P3, this takes place via a drive 240, which is connected in the example shown by a gear train 241, 243 to the shaft of the contour roller 220. The optional additional contour roller 230 is synchronized with the second contour roller 220 insofar as it is rotated on the same drive 240 via the gears 241, 242 about the axis P4.

[0025] As may be seen in FIGS. 1, 2 and 3, the contour rollers 220 and 230 include grooves or recesses 221-223 and 231-223, in which the wire outlet nozzles 202 are situated.

[0026] As is particularly apparent from FIGS. 2 and 3, in which an additional optional contour roller 320 is situated below the wire outlet nozzles 202, the grooves extend circumferentially around the respective contour roller 220, 320. However, the plane defined by the direction of extension of each groove differs from groove to groove. Like the contour roller 230 in FIG. 1, the contour roller 320 is also optional. Instead of the contour roller 230, a slide bearing, for example, could also be present, on which the nozzles glide along in arrow direction P1 or P2. The contour roller 220 may then also be situated above the nozzles (as in the example shown) or also below the nozzles 202, in this case, for example, a slide bearing may be located above the nozzles 202.

[0027] Whereas a middle groove of the contour rollers 230, 320 has a plane of extension, which extends parallel to the direction L perpendicular to the rotation axes P3 and P5, these planes of extension are increasingly tipped, the further outward on the respective contour roller 220, 320, the corresponding groove 221, 222, respectively, 223 or 321, 22, respectively, 323 is located. This is indicated in FIG. 2 in the upper contour roller 220 by the angles .sub.1 and .sub.2 to the perpendicular (to the rotation axis P3, respectively, P5), which become increasingly larger toward the outside (in FIG. 2, .sub.1>.sub.2 applies). The result of this is that a movement of the nozzles 202 takes place when the contour rollers 220 or 320 are rotated, since each nozzle 202 is situated in a corresponding groove of the contour roller 220, respectively, 320 and is forcibly guided. Thus, when the contour roller rotates about the axis P3, respectively, P5, the nozzles shown in the configuration in FIG. 2 are displaced outwardly, depending on the angle of inclination of the plane of extension of the individual grooves 221, 222, 223, respectively, 321, 322, 323. Since the outer-lying grooves are more sharply inclined, the nozzles 202 situated therein are displaced further outwardly in the direction P1, respectively, P2. The displacement in the center of a contour roll is corresponding minimal or, at least in the case of nozzle 202, does not even take place.

[0028] A 180 rotation of the contour roller 220, 320 in the configuration from FIG. 2 leads to the position shown in FIG. 3. Whereas in FIG. 2 the nozzles 202 are spaced minimally apart next to one another, the spacing of the nozzles 202 in FIG. 3 is correspondingly maximal. This is due to the fact that each groove set in the axial direction P3, respectively, P5 rolls around the rotation axis P3, respectively, P5 during rotation of the corresponding contour roller 220, 320. As a result of this effect, the plane of extension of the grooves (depicted by the angles .sub.1 and .sub.2 to the perpendicular L in FIG. 2) migrates and assumes new angles perpendicular to the respective rotation axis, which are referred to in FIG. 3 by way of example of the upper contour roller 220 by .sub.1 and .sub.2, wherein here again .sub.i>.sub.2 is applicable.

[0029] In this way, it is possible, depending on the angle setting, i.e., the rotational position of the contour rollers 220, 320, to vary the spacings between the nozzles 202 as desired, which may be adjusted by a corresponding machine control. Thus, it is possible to set the machine control of a winding device, in particular, of a wave winding device, in such a way that the spacing of the nozzles 202 is reduced or increasedin particular, continuously, during the course of the process.
