    The invention relates to a device and a method for forming a conductor package provided for insertion into a stator or rotor.
    As an important functional components of an electric motor whose stator and / or rotor are usually formed from a plurality of electrical conductor elements, which are arranged in or around an electromagnetically excitable core. In this case, the conductor elements are arranged such that e.g. a plurality of windings is formed in a stator, which cause the generation of an electromagnetic field when current flows through. Frequently, U-shaped conductor elements are used in stators and electrically connected to one another according to a predetermined interconnection pattern. The correct positioning of the often different length U-shaped conductor elements in the stator is associated with great manual effort, or can only be accomplished by means of complicated systems.
    For this purpose, DE 102014226224 A1 introduces a method for forming U-shaped winding elements, wherein an inner and an outer tool part of a setting tool are rotated against each other and the winding elements are gripped by one tooth each and a rod section of the winding element is reshaped.
    However, it would be advantageous to arrange the U-shaped conductor elements in a predeterminable position and to form a conductor package together before insertion into a stator or rotor. This object is achieved by the present invention, overcoming the disadvantages of the prior art, and discloses an apparatus and method by which a user is able to easily form a conductor package for insertion into a rotor or stator make.
    The inventive method for forming a conductor package provided for insertion into a stator or rotor comprises the steps of providing a plurality of substantially U-shaped conductor elements each having a first rod portion and a first conductor end and a second rod portion and a second conductor end, which rod portions are connected by a substantially arcuate connecting portion, - at least partially receiving the first bar sections in receptacles, which receptacles are formed on an outer periphery of an inner holding device, - prepositioning the second bar sections by moving a respective second bar section into proximity to a first bar section of another Ladder element, by means of a positioning device, - and gripping each formed of a prepositioned second rod portion and a radially adjacent, first rod portion Stababschnittspa by gripping elements guided in the radial direction towards the inner holding device, at least one gripping device arranged circumferentially around the inner holding device, wherein the first bar sections are at least partially rotatably received in the receptacles before the second bar sections are prepositioned and the second bar sections are free-standing ring-shaped around the outer circumference of the inner holding device radially outward from the outer circumference, and that the second bar sections are pushed for prepositioning by means of a positioning element of the positioning device guided circumferentially as well as radially towards the outer circumference of the inner holder, the ladder elements being respectively about a first longitudinal axis of the bar partially rotatably recorded in the recordings, first rod sections are rotated.
    By the method according to the invention, a pre-positioning, ie alignment, of the U-shaped conductor elements is achieved in a relatively simple manner in accordance with a predeterminable interconnection pattern. By the inventive leadership of the positioning in the circumferential direction and simultaneous movement in the radial direction inward a relatively simple rotational movement of the conductor elements. The first rod sections are arranged in the course of the Vorpositionierung by the twisting movement, without disadvantageous reshaping of the conductor elements, provided with second bar sections of another conductor element in the radial direction directly adjacent, whereby a respective rod section pair is formed. Thus eliminates any step of forming the conductor element, which would usually lead to a cross-sectional change and thus a change in resistance of the conductor element. The application or rotation of the conductor elements by the positioning element can take place in one or more revolutions around the inner holding device.
    The first rod portions of the conductor elements are only partially, so with a longitudinal part of the rod portion in contact, whereby only low frictional forces on the conductor element occur. This is advantageous because the conductor elements are usually provided with an insulation, which should not be damaged in the positioning of the rod sections to form the rod section pairs, respectively the conductor package.
    The prepositioning thus described thus describes the formation of a conductor package, with which a subsequent gripping operation of the conductor package or to the subsequent transfer and / or insertion process of the conductor package into a stator or rotor is significantly facilitated.
    Furthermore, it may be expedient if, during the provision, the picking up and the pre-positioning, the conductor elements are contacted by the respective levers which are rotatable around the first rod longitudinal axis of the respective first rod sections on the first and second rod sections and the levers are engaged during pre-positioning the second bar sections by a Einschwenkbewegung, analogous to the Andrückbewegung the second bar sections by the positioning, in the circumferential and radial directions.
    By using levers, the process reliability can be increased because the second rod sections are guided in the radial direction and / or circumferential direction. This is particularly advantageous for relatively long U-shaped conductor elements.
    Furthermore, provision can be made for the conductor elements to be contacted by at least one guide groove on the second rod section during provision, picking up and pre-positioning, and for the second rod sections to be guided by the positioning guide during the pre-positioning of the second rod sections by means of the respective guide groove. and radial direction.
    In a similar manner as with the use of levers, by guiding the second bar sections within a guide groove of a slide, a very accurate positioning of the second bar sections on the intended first bar sections can be made.
    It is conceivable that several scenes are arranged one above the other in the axial direction and thus provide a multipoint support of the second bar sections in the axial direction, which can lead to an additional increase in the security of the conductor elements against unintentional tilting. This measure is particularly advantageous for very long conductor elements. Similarly, it is conceivable that both levers and at least one link, as well as a plurality of axially superposed levers are used.
    In addition, it can be provided that the positioning element is formed by a rotatably arranged on the positioning roller element, and that this roller element unrolls during the Vorpositionierens the second rod sections on the second rod sections or actively driven on the second rod sections is unrolled.
    The pressing of the second bar sections is accomplished by rolling in a material-friendly manner, whereby damage to the conductor elements or their isolation can be efficiently avoided. The approach of the positioning to the inner holder can be completed within a cycle, or even several rounds. The pressing, ie pre-positioning, of the second rod sections can thereby be carried out very precisely, which can contribute to an increase in process reliability.
    Also advantageous is a method, according to which it can be provided that the receptacles for the first rod sections are formed by outwardly open, extending in the axial direction receiving grooves, and that the first rod sections are at least partially included in these grooves, wherein during recording of the first sleeve sections and during the pre-positioning of the second rod sections around the first rod sections at least partially a sleeve is arranged, which sleeve the first bar sections immediately adjacent in the radial outward direction and secures during Vorpositionierens the first rod sections against displacement in the radial direction to the outside.
    The sleeve is thus temporarily provided as a limitation of the first rod sections in the radial direction, whereby a safeguard against tilting or displacement can be avoided to the outside. The sleeve may be arranged adjacent to the first rod sections, or separated by a small gap thereof, so as not to impede a rotational movement of the second rod sections. The sleeve can advantageously be arranged below the inner holding device or the receptacles.
    According to a development, it is possible to apply the second rod sections for pre-positioning on an outer sleeve lateral surface of the sleeve. This can be advantageous during pre-positioning, since the second rod sections are thus positioned in the immediate vicinity of the intended first rod sections but still have no contact. By means of this intermediate step possibly not correctly aligned second conductor sections can be precisely aligned by an additional rotation of the positioning in the circumferential direction relative to the first bar sections.
    Furthermore, it is expedient that, after the pre-positioning of the second rod sections, the sleeve is displaced downwardly in the axial direction with respect to the inner holding device into a region of the second conductor ends of the second rod sections, and that thereafter the second conductor ends of the prepositioned second rod sections by means of the positioning element or the Gripping elements of the gripping device are arranged circumferentially in an upper end portion of the sleeve, upwardly open positioning grooves are pressed.
    It can be released by the displacement of the sleeve thus the second rod sections relative to the assigned first rod sections in the radial direction and applied to these precisely. The rod section pairs thus formed are thus distributed substantially uniformly in the circumferential direction. The grooves of the receptacles of the inner holder may have a sufficient groove depth in the radial direction to accommodate the rod portion pair, or may be provided on the sleeve positioning grooves at least a lower portion of the second conductor ends. As a result, a displacement in the axial, radial and circumferential direction of the conductor pairs formed can be efficiently avoided.
    In addition, it can be provided that the first conductor ends of the first rod sections are supported during the pre-positioning of the conductor elements by means of a support device with at least one support surface in the axial direction.
    As a result, an unintentional slipping of the conductor elements in the axial direction can be avoided particularly well. The risk of jamming of the conductor elements in the pre-positioning is thereby also reduced.
    Furthermore, it can be provided that, during the pre-positioning of the second bar sections, a first bar section of at least one of the ladder elements is supported by means of at least one height-adjustable support surface of the support device in a different height relative to other ladder elements.
    The support device can thus form different levels of support surfaces for the first conductor ends in the axial direction. This is particularly advantageous for different length conductor elements, as they may be provided under certain circumstances to bridge different long groove jumps. Thus, it is necessary that individual second bar sections must be rotated over a greater or lesser number of ladder elements so that the second bar section can be correctly positioned with a first bar section of a designated ladder element. Due to the height adjustability of at least individual support surfaces of the support device in the axial direction thus jamming of the conductor elements can be avoided during Vorpositionierens.
    According to a particular embodiment, it is possible that in the region of the first conductor ends of the first rod sections a Nutenring is arranged, are provided at the Nutenringumfang outwardly open, vertically extending Halterungsnuten, and that first conductor ends of the first rod sections before pre-positioning of the second rod sections in these retaining grooves are introduced.
    The arrangement of the Nutenrings lies in the axial direction below the inner holder whereby an additional, second bearing surface for the first bar cuts is created. The first bar sections can thereby be secured at least two points, at least in sections, with respect to a tilting in the radial direction. This promotes increased process stability.
    The pre-positioning device according to the invention for forming a conductor package provided for insertion into a stator or rotor comprises: an inner holding device with receptacles arranged along an outer circumference of the inner holding device and provided for at least partially receiving first bar sections with first conductor ends of substantially U-shaped conductor elements; a positioning device for pre-positioning second rod sections with second conductor ends of the conductor elements, which second rod sections are connected to the first rod sections by a substantially arcuate connecting section, at least one gripping device which can be arranged around the inner holding device in the circumferential direction and has gripping elements that can be adjusted in the radial direction relative to the inner holding device for gripping each of a prepositioned second rod portion and an adjacent, first rod portion formed rod portion Spaaren is trained. The pre-positioning device according to the invention is characterized in that the receptacles are dimensioned such that the first bar sections are at least partially rotatably receivable in the receptacles, and that the positioning device for pre-positioning the second bar sections comprises a positioning element spaced radially outward from the inner holding device , Which positioning element is circumferentially drivable in the circumferential direction of the inner holding device and at the same time radially inwardly adjustable.
    By means of the pre-positioning device according to the invention, the method steps described above can be carried out in a relatively simple manner. Due to the described design and arrangement of the individual components or sub-devices, it is possible to position a plurality of conductor elements according to a predetermined interconnection pattern in such a way that a conductor package is formed. This makes it possible with low cost to accomplish a comparatively fast and precise pre-positioning of the conductor elements, which is especially important in high quantities.
    The receptacles have at least one longitudinal extension in the axial direction, which makes it possible to contact the first bar sections at least in sections, as a result of which tilting during pre-positioning can be reduced. The embodiment of the positioning element of the positioning device which can be driven in the circumferential direction and is radially inwardly adjustable has the advantage that the second rod sections can be easily aligned by means of one or more circulating movements of the positioning element relative to first rod sections provided therefor.
    The positioning device and / or the gripping device can be designed to be displaceable in the axial direction in order to ensure a sequential sequence of the method steps. The gripping elements can be segmented and designed to be adjustable or displaceable relative to the inner holding device in the radial direction. In this way, a temporary fixation of the conductor package can be made in a simple manner after pre-positioning, after which a transfer to an insertion station or any subsequent process steps can be performed, which will not be discussed in detail here.
    Furthermore, it may be expedient if a lever guide device is formed with a number of levers corresponding to the number of conductor elements, wherein the levers are bow-shaped with a predeterminable lever length and two horizontally extending, pointing in the same direction, lever arms are formed, wherein the first Lever each having a first rod portion of the conductor element form compatible first rod portion receptacle, and wherein the second lever arm in each case has a second rod portion of the conductor element form compatible second rod portion receptacle, and the levers about a respective first Stababschnittsaufnahmeachse, which are aligned with a first rod longitudinal axis of the respective first rod sections , Are rotatably mounted and wherein the levers are distributed in the circumferential direction and arranged offset in the axial direction such that all levers are pivoted in the circumferential direction.
    The design of the lever guide device can be done in different ways, with only the pivotal movement of the lever in the circumferential direction must be able to occur freely. By forming the levers with respective rod portion receivers for the first and second rod portions, temporary guidance of the conductor members during pre-positioning can be ensured. As a result, a precise alignment of the second bar sections is favored over the first bar sections provided for this purpose and tilting of the ladder elements is avoided.
    Furthermore, it can be provided, a backdrop with one, the number of conductor elements corresponding, number of guide grooves is formed, wherein the guide from a, the inner holder facing inner diameter starting, as the backdrop in the axial direction penetrating openings, and in the circumferential and radial directions are formed circular arc.
    In this way, the guidance of the second bar sections can be favored during Vorpositionierens. The backdrop can be designed as a crank disc represent an independent or combined leadership with the above-described lever guide device for the second conductor sections. The slide can also be displaced in the axial direction and / or rotatable in the circumferential direction. This can facilitate the alignment of the slide against the inner holder and simplify the provision of the conductor elements on or in the inner holder.
    In addition, it can be provided that the positioning element is formed by a rotatably arranged on the positioning roller element, said roller element is rotatably mounted without drive or is operatively connected to a drive member for actively driven rotation.
    It is conceivable that the positioning element is designed as a wedge, roller or similar pressure element. In any case, the pre-positioning of the second rod sections can be accomplished by rolling or pressing in the radial and circumferential direction in a material-friendly manner, whereby damage to the conductor elements or their isolation can be efficiently avoided. As a driving element, for example, electric motors in question.
    Also advantageous is an expression, according to which it can be provided that the receptacles for the first bar sections are formed by outwardly open, extending in the axial direction receiving grooves, and that a sleeve is formed, which is arranged below the receiving grooves, wherein a sleeve inner diameter of the Sleeve is chosen such that the sleeve for the first rod sections forms a boundary in the radial direction outwards.
    The sleeve can in this case be designed to be displaceable in the axial direction and thus serve only temporarily as a stop in the radial direction for the first rod sections. As a result, a tilting of the conductor elements is avoided whereby the process reliability can be increased. The sleeve also has a radially outer contact surface, which can be used for temporary application of the second rod sections. It is thus possible that, during the pre-positioning, the second rod sections are first applied to this contact surface before the sleeve is displaced and the second rod sections can be attached to the associated first rod sections. The accuracy of the Vorpositioniervorgangs can hereby be increased.
    Furthermore, it may be expedient if the sleeve and in an upper end region arranged in the circumferential direction, upwardly open positioning grooves, which positioning grooves are formed for receiving the second conductor ends of the second rod sections.
    The positioning grooves can preferably extend horizontally and emanate from a front end of the sleeve. The depth of the positioning grooves can be chosen such that a recording of the second conductor ends, at least in sections, can take place. The sleeve should be designed to be displaceable in the axial direction. Pushing the second conductor ends into the positioning grooves provided for this purpose can be done by an additional circulation of the positioning, or by the gripping device.
    In addition, it may be provided that a guide element is formed with positioning grooves, which positioning grooves are formed for receiving the second conductor ends of the second rod sections.
    This alternative embodiment can be carried out alternatively to a sleeve which can be displaced in the axial direction, in order to permit a temporary guidance of the second conductor ends in the axial, circumferential and / or radial direction.
    Furthermore, it may be provided that a support device is formed with at least one support surface, which support device is provided for axially supporting the first rod sections.
    The support device allows during the provision, the pre-positioning and / or the gripping of the conductor elements a correct positioning of the conductor elements in the axial direction. Hereby, an unintentional sliding down of individual conductor elements in the axial direction can be efficiently avoided.
    According to a particular embodiment, it is possible that the supporting device has at least one height-adjustable support surface.
    The support device may be made of e.g. be constructed a plurality of annular or disc-shaped elements which serve in the axial direction as a stop for the first conductor ends. The support device may therefore be structured in segments, wherein it may consist of at least two radially in the same direction having the same rings or discs. At least one of these rings is additionally broken in the circumferential direction at designated positions in the axial direction, while at least one of these rings or discs may have extensions in the axial direction. Such a construction of the support device makes it possible to provide the support elements of different lengths in the axial direction for positions provided in the circumferential direction. At least individual support surfaces of the support device are thus displaceable in the axial direction, whereby only selectable conductor elements can be moved in the axial direction. This offers the advantage that the rotational movement in the circumferential direction is made possible for the necessary rotation of the second rod sections for correct pre-positioning in relation to the first rod sections provided therefor, without adjacent conductor elements colliding with one another. This is particularly useful with a different number of Nutsprüngen, so if individual conductor elements are provided according to the interconnection pattern opposite circumferentially adjacent conductor elements shorter o the longer distances, useful.
    According to an advantageous development can be provided, a Nutenring is formed, are provided at the Nutenringumfang outwardly open, vertically extending Halterungsnuten, which support grooves are formed for at least partially receiving the first conductor ends of the first rod sections.
    The Nutenring can serve as a stop for the first rod sections in the radial direction inwards. The Nutenring thus provides at least in sections a second support surface for the first rod sections. As a result, tilting of the conductor elements from their vertical alignment along the axial direction can be avoided in a simple manner.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    An embodiment of the pre-positioning device 34 according to the invention is shown in FIG. The holding device 2 has a vertical main axis which serves as a reference axis. The axial direction 19 extends parallel to the vertical main axis of the inner holding device 2. The holding device 2 has an outer outer periphery 16, on which a plurality of receptacles 10 can be seen. The receptacles 10 may be designed as closed receptacles 10 or also as receptacle grooves 11, as shown in FIG. 1, in which the first bar sections 3 can be at least partially accommodated. To simplify the illustration, only five conductor elements 1 are shown.
    Furthermore, a positioning device 12 is shown in Fig. 1, which is arranged above the inner holder 2 in the embodiment. The positioning device 12 in this case comprises a positioning element 13 which is designed to be displaceable or movable in the radial direction 18 and rotatable in the circumferential direction 17. The positioning element 13 may further be used as e.g. Roller element 23 may be formed, which is additionally rotatable about a vertical roller axis as shown in Fig. 1. The positioning device 12 may further comprise a drive member 44, which for driving the positioning device 12 and / or the
    Positioning element 13 may be provided. It is also possible, additional drive members 44 may be attached to the positioning device 11, the positioning member 13, but also the holding device 2 to, for example, the displacement of the positioning member 13, or the positioning device 12 to accomplish relative to the inner holder 2.
    In Fig. 1 and in particular Fig. 2 are exemplary some conductor elements 1 can be seen. The first and second bar sections 3, 6 of a conductor element 1 are connected via a substantially arcuate connecting section 8 and have a first 4, or second, conductor end 7. These connecting portions 8, as well as the first and second bar sections 3, 6 may be designed to be of different lengths depending on the intended arrangement and thus the distance to be bridged in the conductor package to be formed. As shown in FIG. 2, conductor elements 1 with different lengths of first and second bar sections 3, 6 can be used. Furthermore, a first rod longitudinal axis 5 can be seen for the first rod section 3, around which a rotational movement of the second rod section 6 takes place during the pre-positioning. For the Vorpositionierens can be used as a kind of setup help various supportive elements. FIGS. 3 and 4 show by way of example the use of a lever guide device 35 or a link 22.
    The lever guide device 35 in FIG. 3 a comprises a number of levers 20 corresponding to the number of conductor elements 1, which are each designed to be coupled to the first and second rod sections 3, 6 of a conductor element 1. Such a lever 20 is shown schematically in Fig. 3b. Each lever 20 has at least one first rod portion receptacle 38, which is intended for temporary connection with at least a portion of a first rod portion 3. The first rod section receptacle 38 has a first rod section receiving axis 41, which runs along the receiving opening and thus is oriented normal to the longitudinal extension of the lever 20. This rod portion receiving axis 41 coincides in the use of the lever 20 with the first rod longitudinal axis 5 of the conductor elements 1 during pre-positioning. It is thus formed a common axis of rotation about which each of the second rod portion 6 is rotated. Each lever 20 also has a first lever arm 37, or second lever arm 39, on, wherein the two lever arms 37, 39 are connected to each other via a connecting path. The entire length of a lever 20 may correspond to the predetermined position of the conductor element 1, and thus with the length of the connecting portion 8 of the intended conductor elements 1, and is accordingly selected by the person skilled in the art. The levers 20 in FIG. 3 a-c furthermore have a second rod section receptacle 40, which are provided for temporarily receiving and above all guiding the second rod sections 6.
    The state before pre-positioning is symbolically shown in Fig. 3a. The provided conductor elements 1 are arranged in the inner holding device 2 with their first bar sections 3. The levers 20 are positioned relatively close to the respective conductor ends 4, 7 in the illustrated form. The levers 20 may be arranged along the rod longitudinal axis 5 in the axial direction 19 also at other positions, preferably offset from one another. However, a collision of the levers 20 during pre-positioning should be avoided. A simple variant is shown in Fig. 3a, wherein the lever guide device 35 is e.g. are shown as a disk with rotatably mounted spacers to the individual levers 20. Of course, the arrangement of the levers 20 can also be carried out by the person skilled in the art in a different manner, or even differently shaped connecting sections of the individual levers 20 can be used. Decisive is a pivoting or rotational movement of the lever 20, respectively the conductor elements 1, to allow unhindered in the circumferential direction 17 to position the second bar sections 6 at the intended first bar sections 3 of another conductor element 1. An achievable final state after pre-positioning can be seen in Fig. 3c. It is clear to the person skilled in the art that the levers 20 ensure guidance of the second bar sections 6, whereby an exact positioning can take place. Thereafter, the following gripping, transfer and / or insertion process steps are not explained in detail here.
    Analogous to FIGS. 3 a and 3c, the use of a guide 22 with guide grooves 21 can be seen from FIGS. 4 a and 4b. Again, only a few conductor elements 1 are shown for ease of illustration. FIG. 4 a shows the state before pre-positioning, in which the provision of the conductor elements 1 can be detected. As a result of the rotational movement of the positioning device 12 during pre-positioning, the second bar sections 6 are rotated along the guide grooves 21 to their intended first bar sections 3 of another ladder element 1. As shown in Fig. 4a and Fig. 4b, the guide grooves 21 of the link 22 are formed as axially continuous openings extending from one of the inner holder 2 facing inner diameter 42 in the circumferential 17 and radial 18 arcuate. In Fig. 4b, a preliminary end position after the pre-positioning of the second bar sections 6 is shown.
    FIG. 5 shows, by way of example, an inner holding device 2 with a number of conductor elements 1. Furthermore, a sleeve 24 can be seen, which is displaceable in the axial direction 19 at least up to an upper position, which corresponds to a flush termination of the upper end portion 26 of the sleeve 24 with the top of the inner holder 2. The sleeve inner diameter 43 can be selected such that the first rod sections 3 are prevented from falling out in the radial direction 18 by the sleeve 24. As a result, during the pre-positioning, that is to say the pivoting movement of the second bar sections 6 in the peripheral 17 and radial direction 18 to the first bar sections 3, the second bar sections 6 can be applied, for example, to the sleeve lateral surface 25 of the sleeve 24. In the selected representation in Fig. 5, the sleeve 24 is in a lower position, whereby the second bar sections 6 are freely movable and thus flush with the first bar sections 3 can be applied. As can further be seen in FIG. 5, the sleeve 24 in the upper end region 26 has outwardly extending positioning grooves 27 in the radial direction 18 and upwardly open in the axial direction 19. These positioning grooves 27 can serve to receive the second conductor ends 7 of the second rod sections 6, and therefore have different groove depths in the axial direction 19 corresponding to the individual length of the second rod sections 6.
    Furthermore, exemplary embodiments are shown in FIGS. 5 and 6 which have a grooved ring 31 with a groove ring circumference 32. On Nutenring 31 18 outwardly open, vertically extending mounting grooves 33 are arranged in the radial direction. The Nutenring 31 may, for at least temporary support of the first rod sections 3 in the Halterungsnuten 33, be designed to be displaceable in the axial direction 19 and is preferably arranged in the region of the first conductor ends 4.
    As an alternative to a sleeve 24 designed to be displaceable in FIG. 5, a guide element 28 may be provided with positioning grooves 27. The positioning grooves 27 are analogous to the positioning grooves 27 of the sleeve 24 for receiving the second conductor ends 7 of the second bar sections 6 to allow temporary guidance of the second conductor ends 7 in axial 19, circumferential 17, and / or radial direction 18. On the separate representation of such a guide element 28 is therefore omitted and referenced at Fig. 5 at this point.
    In Fig. 6, an embodiment is shown, which shows a supporting device 29 with a plurality of support surfaces 30, which are formed horizontally. These supporting surfaces 30 serve to support the first bar sections 3 in the axial direction 19. The illustrated supporting device 29 comprises a disk element which is divided several times in the circumferential direction 17 and serves as a stop for the first conductor ends 4 in the axial direction 19. This disk element is further broken in the circumferential direction 17 at designated positions in the axial direction 19, and at these positions extensions of a further arranged in the axial direction 19 further disk element can be seen. As a result, in the exemplary representation all first conductor ends 4 are temporarily held in the same vertical position. The structure of the support device 29 can thus be adapted accordingly that differently long conductor elements 1 are provided in the axial direction 19 at associated for circumferential direction 17 provided support surfaces 30. In this case, a distance of the two disc elements shown in Fig. 6 of the support device 29 can be seen, which can be reduced to each other in displacement of one of the two disc elements in the axial direction 19, whereby at least individual support surfaces 30 of the support device 29 in the axial direction 19 are displaced. As a result, only selectable conductor elements 1 can be displaced or raised in the axial direction. The second bar sections 6 shown in FIG. 6 have been rotated in the circumferential direction 17 for correct pre-positioning with respect to the first bar sections 3 provided therefor, without neighboring ladder elements 1 colliding with one another. The bridging of different distances by the respective conductor elements 1 for correct positioning according to the interconnection pattern can be easily understood in FIGS. 5 and 6 using the example of the "longer" conductor element.
