Description

[0001] The invention relates to a method for producing a wiring harness according to claim 1 and a wiring harness produced by the method according to claim 9.

[0002] Typically, cables are laid on a form board and, after the cables have been laid on the form board, taped. This involves wrapping a tape from a narrow roll around the wires of the wiring harness to bundle the cables together. This process is usually done manually and is therefore time-consuming.

[0003] It is an object of the invention to provide an improved method for producing a wiring harness and an improved wiring harness.

[0004] This object is achieved by a method according to claim 1 and by a wiring harness according to claim 9. Advantageous embodiments are specified in the dependent claims.

[0005] It has been recognized that an improved method for producing a cable harness can be provided by providing a first textile fabric, a second textile fabric, and a cable arrangement having at least a first and a second electrical cable. The second textile fabric is spread out. The cable arrangement is placed on the second textile fabric. A course of the cable arrangement is determined on the second textile fabric. The first textile fabric is applied to the cable arrangement and to the second textile fabric and mechanically connected to one another in a first partial region. In a second partial region adjoining the first partial region, the cable arrangement is held between the first textile fabric and the second textile fabric. A cutting pattern is determined on the basis of the determined course of the cable arrangement on the second textile fabric.Based on the pattern, the wiring harness is cut out of the first and second textile fabric.

[0006] This design has the advantage that the wiring harness can be manufactured particularly easily and cost-effectively in just a few process steps. In particular, by determining the routing of the cable arrangement, a precise arrangement of the electrical cables to form the cable arrangement on the second textile fabric is no longer necessary, and high tolerances in the positioning of the electrical cables to form the cable arrangement can be accepted. This makes the process particularly suitable for fully automated production of the wiring harness.

[0007] In a further embodiment, a predefined width of the first and / or second partial section is taken into account when determining the cutting pattern. This embodiment has the advantage that the predefined width provides sufficient space and material of the second textile fabric to ensure a secure mechanical connection between the first textile fabric and the second textile fabric.

[0008] In a further embodiment, the first textile fabric and the second textile fabric are connected to one another in the first partial region in a materially bonded and / or positively connected and / or non-positively connected manner. In particular, the first textile fabric and the second textile fabric can be glued and / or welded and / or riveted and / or screwed together, for example. It is also possible for the first textile fabric and the second textile fabric to be sewn together in addition to or as an alternative to the materially bonded connection. Tack fastening would also be possible. This configuration has the advantage that the first textile fabric and the second textile fabric are connected to one another particularly quickly and mechanically reliably.

[0009] In a further embodiment, at least the first cable and / or the second cable are mechanically connected, at least in sections, to the first textile fabric and / or to the second textile fabric. This configuration has the advantage that the cable harness is mechanically rigid due to the connection between the first electrical cable and / or the second electrical cable and the textile fabric, and bending of the cable harness due to the mechanical connection can thus be minimized. A material-to-material connection, for example an adhesive connection, between the electrical cables and the first and / or second textile fabric is particularly suitable.

[0010] In a further embodiment, the second textile fabric is unwound from a second roll and spread out over a surface. The first textile fabric is unwound from a first roll. This embodiment has the advantage that the first textile fabric and / or the second textile fabric can be provided in quasi-endless operation and setup times can therefore be kept to a minimum. In a further development, the first textile fabric and the second textile fabric can be unwound from a common first roll. First, the second textile fabric is unwound from the first roll, cut, and spread out. The first textile fabric is then unwound from the first roll in the same way, cut, and applied to the arrangement of second textile fabric and the cable arrangement.

[0011] It is particularly advantageous if, for example, after unrolling the first and / or second textile fabric from the first or second roll, an adhesive layer is applied locally, for example by means of an adhesive tape dispenser, to at least one of the two textile fabrics. This can be done, for example, before applying the cable arrangement. In a further embodiment, at least one first opening is cut into the first textile fabric and the second textile fabric. The first cable and / or the second cable is applied to the second textile fabric at the first opening. The first textile fabric is positioned on the second textile fabric and the cable arrangement in such a way that the first opening of the first textile fabric overlaps the first opening of the second textile fabric.Alternatively, it is also possible for at least one first opening to be cut into the first textile fabric and the second textile fabric, wherein the cable arrangement is placed on the second textile fabric before the first opening is cut into the first textile fabric and the second textile fabric.

[0012] This design has the advantage that the first opening can be used to define an exposed area of ​​the cable harness, preventing unwanted connection, particularly unwanted adhesion, of the electrical cables in the exposed area to the textile fabric. The exposed area can be used, for example, to attach a contact device to the cable assembly.

[0013] In a further embodiment, the cutting pattern opens into the first opening. This allows the length of a cut to be made for the cutting pattern to be kept short, so that the production time for cutting based on the predefined cutting pattern can be kept short.

[0014] In a further embodiment, the second textile fabric and the first textile fabric are pressed together. In the pressed state, the first textile fabric and the second textile fabric are mechanically connected to one another in the first partial region.

[0015] An improved wiring harness for a vehicle can be provided in that the wiring harness has a first textile fabric, a cable arrangement, and a second textile fabric. In a first partial region, the first textile fabric and the second textile fabric lie against one another and are mechanically connected. In a second partial region adjoining the first partial region, the cable arrangement is arranged between the first textile fabric and the second textile fabric. This configuration has the advantage that the two-layer design of the textile fabric can prevent unwanted breakage of a high bend in the wiring harness in a tight radius of the first and second textile fabric. Furthermore, the wiring harness is particularly rigid and has high vibration resistance.

[0016] In a further embodiment, the first textile fabric and the second textile fabric are integrally connected to one another in the first partial region. Additionally or alternatively, the first textile fabric is integrally connected to the cable arrangement and / or the second textile fabric is integrally connected to the cable arrangement in the second partial region. This allows the cable harness to be manufactured particularly easily and cost-effectively.

[0017] In a further embodiment, the first textile fabric and the second textile fabric in the first partial area are each formed as a single layer, extending away from the cable arrangement. As a result, the cable harness in the first partial area is designed as a tab, which can be used to secure the cable harness in the vehicle.

[0018] In a further embodiment, the first textile fabric and the second textile fabric have a circumferentially extending cut surface. The cut surface is designed to run parallel to the cable arrangement, at least in sections. This configuration has the advantage that the cut surface is arranged at a sufficient distance from the cable arrangement, thus providing sufficient width for the first section to be fastened in the vehicle.

[0019] In a further embodiment, fibers of the first textile fabric and / or the second textile fabric are welded together at the cut surface. This prevents unwanted unraveling or unraveling of the first and / or second textile fabric.

[0020] The invention is explained in more detail below with reference to the figures. These show: Fig. 1 a perspective view of a wiring harness; Fig. 2 a sectional view along a Fig. 1 shown section plane AA through the Fig. 1 wiring harness shown; Fig. 3 a production plant for the production of the Fig. 1 and Fig. 2 wiring harness shown; Fig. 4 a sectional view through a first textile fabric wound on a second roll; Fig. 5 a sectional view through a second textile fabric wound on a second roll; Fig. 6 a flow diagram of a process for producing the Fig. 1 and Fig. 2 using the wiring harness shown in Fig. 3 shown production facility; Fig. 7 a plan view of the first and second textile fabrics after a second process step; Fig. 8 a plan view of the first and second textile fabrics after a third process step; Fig. 9 a plan view of the second textile fabric after a fifth process step; Fig. 10 a plan view of the second textile fabric after a sixth process step; Fig. 11 a plan view of the first and second textile fabrics after an eighth process step; and Fig. 12 a plan view of the first and second textile fabrics after a tenth process step.

[0021] Fig. 1 shows a perspective view of a wiring harness 10.

[0022] The cable harness 10 is designed, in the embodiment, for a motor vehicle by way of example. The cable harness 10 has at least one cable arrangement 20. In the embodiment, the cable arrangement 20 has at least a first electrical cable 25 and a second electrical cable 30. The first electrical cable 25 and / or the second electrical cable 30 can be provided individually or multiple times for the cable arrangement 20. The first electrical cable 25 can be designed differently than the second electrical cable 30. In particular, the first electrical cable 25 can have a different length and / or a different cross-section and / or a different structure and / or a different color. For example, in Fig. 1, a plurality of first electrical cables 25 and a plurality of second electrical cables 30 are provided. The electrical cables 25, 30 each have an associated electrical conductor (in Fig. 1 not shown), each of which is electrically insulated by a cable sheath 35. The cable sheath 35 comprises, for example, an electrically non-conductive material, in particular a plastic. The respective electrical conductor of the electrical cable 25, 30 can be fine-wire or ultra-fine-wire. The electrical conductor can also be a wire.

[0023] For example, the electrical conductor is made of an electrically conductive material, in particular copper and / or aluminum.

[0024] The electrical cables 25, 30 of the cable arrangement 20 can, for example, be configured to transmit an electrical current for transmitting electrical drive power and / or a data signal for transmitting data information. The electrical cables 25, 30 can each be arranged in a bundle in the cable arrangement 20.

[0025] The cable harness 10 further includes a sheath 40. The sheath 40 includes a first textile fabric layer 155 and a second textile fabric layer 175. Of course, it is also possible for the sheath 40 to include additional textile fabric layers.

[0026] In the embodiment, the first textile fabric layer 155 is mechanically connected, for example, by a material bond and / or form-fitting connection, to the second textile fabric layer 175. The first textile fabric layer 155 and the second textile fabric layer 175 enclose the cable arrangement 20 in a first partial region 55 of the cable harness 10. In the first partial section 55, the first and second electrical cables 25, 30 of the cable arrangement 20 are mechanically connected to one another by the sheathing 40.

[0027] In a second section 60 of the cable harness 10, which adjoins, for example, the first section 55, the cable arrangement 20 protrudes beyond the sheathing 40. In the second section 60 of the cable harness 10, for example, a contact device 65 can be arranged to electrically connect the electrical cables 25, 30 to another electrical component, for example a control unit or a consumer, in the vehicle. The contact device 65 can also be connected to the Fig. 1 shown wiring harness 10 with another (in Fig. 1 (not shown) wiring harness.

[0028] The sheathing 40 has a cut surface 70, 75 on each of the textile fabric layers 155, 175. The cut surface 70, 75 extends, for example, at least in some areas, substantially similarly, preferably parallel, to a path of the cable arrangement 20.

[0029] Fig. 2 shows a sectional view along a Fig. 1 shown section plane AA through the Fig. 1 wiring harness 10.

[0030] The first textile fabric layer 155 is in Fig. 2, for example, on the top side, and the second textile fabric layer 175 is arranged, for example, on the underside of the cable arrangement 20. The first textile fabric layer 155 and the second textile fabric layer 175 define an interior space 80. The cable arrangement 20 is arranged in the interior space 80.

[0031] In the transverse direction perpendicular to the cable arrangement 20, for example, the cable harness is divided into a first partial region 85, a second partial region 90 and preferably a third partial region 95. The second partial region 90 is arranged in the transverse direction between the first partial region 85 and the third partial region and connects the first partial region 85 to the third partial region 95. In the first and third partial regions 85, 95, the first and second textile layers run parallel to one another and are preferably mechanically connected to one another, preferably directly, for example by means of an adhesive connection. In the second partial section 90, the cable arrangement 20 is arranged in the interior space between the first and second textile layers.

[0032] In the embodiment, the second textile fabric layer 155 extends substantially transversely along a plane over the first to third partial regions 85, 90, 95.

[0033] In contrast, the first textile fabric layer 155 extends laterally to the cable arrangement 20, also in a single plane, and runs parallel to the second textile fabric layer 175. In the area of ​​the cable arrangement 20, the first textile fabric layer 155 is shaped, for example, bulged. Across the first to third partial areas 85, 90, 95, the respective textile fabric 150, 170 and the associated textile fabric layer 155, 175 are formed as a single layer.

[0034] The first and second cut surfaces 70 extend substantially over the entire height of the casing 40 and form a side surface of the first and second textile fabric layers 155, 175, respectively. Furthermore, individual fibers of the textile fabric layer 155, 175 can be melted in regions at the first and / or second cut surfaces 70, 75, so that the individual fibers can be connected to one another, thus eliminating the need for additional sewing or seaming of the cut surfaces 70, 75.

[0035] The one in the Fig. 1 and Fig. The wiring harness 10 shown in Figure 2 has the advantage that it can be manufactured fully automatically with consistently high quality. Furthermore, natural materials, particularly natural fibers, can be used at least partially for the textile fabric layers, thus easily increasing the proportion of natural materials within the vehicle.

[0036] Furthermore, depending on the path of the cable arrangement 20, the cutting surface 70, 75 can be flexibly adapted to the path of the cable arrangement 20. The position of the cutting surface 70, 75 can be easily determined by a predefined distance and, for example, a predefined width of the first and third partial areas 85, 95.

[0037] Furthermore, the wiring harness 10 can be manufactured fully automatically in a production facility.

[0038] Fig. 3 shows a production plant 100 for producing the Fig. 1 and Fig. 2 shown wiring harness 10.

[0039] The production plant 100 has a first cutting machine 115, a first textile fabric storage 105, a second textile fabric storage 110, a layer storage 120, a scanner 125, a pressing device 130, a second cutting machine 135, a control unit 136 and a robot 200.

[0040] The control unit 136 is connected to the robot 200, the first and second cutting machines 115, 135 and the scanner 125 at least in terms of data technology for data exchange and for controlling the robot 200, the first and second cutting machines 115, 135 and the scanner 125.

[0041] In Fig. 3, the first textile fabric storage 105 and the second textile fabric storage 110 are arranged at the beginning of the production plant 100. In this case, Fig. 3, for example, shows a production direction along an x-axis from right to left. The first textile fabric storage 105 can be arranged above the second textile fabric storage. A first roll 140 with a first textile fabric 150 is arranged in the first textile fabric storage 105. A second roll 145 with a second textile fabric 170 is arranged in the second textile fabric storage 110.

[0042] At the beginning of the production plant 100, the first textile fabric storage 105 and the second textile fabric storage 110 are arranged, wherein the associated first roll 140 and the second roll 145 are inserted in each of the first and second textile fabric storages 105, 110. The first textile fabric 150 is unrolled from the first roll 140 along a conveying direction. Likewise, the second textile fabric 170 is unrolled from the second roll 145 along the conveying direction. The conveying direction runs in Fig. 3, for example, in the x-direction. The first cutting machine 115 is arranged downstream of the first and second textile fabric storage units 105, 110 in the conveying direction. Additionally, the production system can have means for transporting the first and / or second textile fabrics 155, 175, for example, driven rollers, within the production system 100.

[0043] The first cutting machine 115 is designed to cut the first and / or second textile fabric 150, 170.

[0044] Downstream of the first cutting machine 115 in the conveying direction, a belt guide is configured such that a first conveying path 190 and a second conveying path 195 are provided. The first conveying path 190 runs, for example, on the upper side to the second conveying path 195.

[0045] The robot is arranged on the second conveyor path 195 and the scanner 125 is arranged downstream of the robot 200 in the conveying direction. Fig. 3, in the z-direction the scanner 125 and / or the robot may be arranged between the first conveyor path 190 and the second conveyor path 195.

[0046] Downstream of the scanner 125, the first conveying path 190 and the second conveying path 195 merge before the pressing device 130. The second cutting machine 135 is arranged downstream of the pressing device 130.

[0047] Fig. 4 shows a section of a cross section through the first textile fabric 150.

[0048] The first textile fabric 155 has a first textile fabric layer 155, preferably a first adhesive layer 160, and a first protective film 165. The first adhesive layer 160 is applied to one side of the first textile fabric layer 155. The first adhesive layer 160 can comprise, for example, a pressure-sensitive adhesive and / or contact adhesive. The first protective film 165 is applied to the first adhesive layer 160 to prevent the first adhesive layer 160 from adhering to the first textile fabric layer 155 in the rolled-up state. Of course, it is also possible to omit the first protective film 165 and / or the first adhesive layer 160.

[0049] The first textile fabric layer 155 may comprise at least one of the following fabrics and / or materials: polypropylene, polyethylene, aramid, textile, natural fiber, hemp, flax, cotton, coconut, synthetic fiber, pitch, chitin, silica, polyvinyl, polyamide, PET, PE, lurex Fig. 5 shows a sectional view through a second textile fabric 170 wound on the second roll 145.

[0050] The second textile fabric 170 can be configured identically to the first textile fabric 150. The second textile fabric 170 can comprise a second textile fabric layer 175, a second adhesive layer 180, and a second protective film 185, wherein, for example, the second adhesive layer 180 is arranged on one side of the second textile fabric layer 175. On a side facing away from the second textile fabric layer 175, the second adhesive layer 180 is covered by the second protective film 185.

[0051] In the embodiment, for example, the first textile fabric 150 and the second textile fabric 170 are identical to one another. Of course, it is also possible for the first textile fabric 150 to be different from the second textile fabric 170. For example, the first and / or second adhesive layer 160, 180 and, if appropriate, the first and / or second protective film 165, 185 can be omitted.

[0052] The second adhesive layer 180 can be configured identically to the first adhesive layer 160. It is also possible for the second adhesive layer 180 to be configured differently from the first adhesive layer 160. This can be the case, for example, in a geometric manner, in particular in a layer thickness of the second adhesive layer 180 compared to the first adhesive layer 160. It is also possible, for example, for the second adhesive layer 180 to have a different material composition than the first adhesive layer 160. In particular, the first adhesive layer 160 and the second adhesive layer 180 can be coordinated with one another in such a way that the first and second adhesive layers 160, 180 adhere particularly well to one another. At least one of the two adhesive layers can also be omitted.

[0053] Fig. Figure 6 shows a flow diagram of a method for producing the Fig. 1 and Fig. 2 shown wiring harness 10 by means of the Fig. 3 shown production plant 100. Fig. 7 shows a plan view of the first and second textile fabrics 150, 170 after a second method step 210. Fig. 8 shows a plan view of the first and second textile fabrics 150, 170 after a third method step 215. Fig. 9 shows a plan view of the second textile fabric 170 after a fifth method step 225. Fig. 10 shows a plan view of the second textile fabric 170 after a sixth method step 230. Fig. 11 shows a plan view of the first and second textile fabrics 150, 170 after an eighth method step 240. Fig. 12 shows a plan view of the first and second textile fabrics 150, 170 after a tenth method step 250.

[0054] In a first method step 205, the first roll 140 is inserted into the first textile fabric storage 105 and the second roll 145 is inserted into the second textile fabric storage 110.

[0055] In the second method step 210, the first textile fabric 150 is unrolled from the first roll 140, spread out and conveyed along the conveying direction in the direction of the first cutting machine 115.

[0056] In the second textile fabric storage 110, in the second method step 210, the second textile fabric 170 is unrolled, spread out and guided along the conveying direction in the direction of the first cutting machine 115.

[0057] In front of the first cutting machine 115, the first textile fabric 150 and the second textile fabric 170 are brought together so that the first textile fabric 150 and the second textile fabric 170 lie flat against each other.

[0058] In the unwound state, in the second method step 210, the first textile fabric 150 and the second textile fabric 170 are fed together and adjacent to one another to the first cutting machine 115 (cf. Fig. 7). The first cutting machine 115 can be designed, for example, as a laser cutting machine. Another configuration of the first cutting machine 115 is also conceivable.

[0059] In the third procedural step 215 (cf. Fig. 8) the first cutting machine 115 cuts at least one first predefined opening 305, preferably a plurality of predefined openings 305, 310, 315, 320, into the adjacent first and second textile fabrics 150, 170. The opening 305, 310, 315, 320 is designed, for example, as a through-opening and thus extends through the two textile fabrics 150, 170. This can be done, for example, by means of a bundled laser beam.

[0060] Furthermore, the textile fabric residues cut from the opening 305, 310, 315, 320 are preferably removed automatically.

[0061] With respect to the first and second conveying directions, the two adjacent textile fabrics 150, 170 are separated from one another downstream of the first cutting machine 115 and guided along the first conveying path 190 and along the second conveying path 195.

[0062] In a fourth method step 220 following the third method step 215, the first textile fabric 150 is transported along the first conveyor path 190. The second textile fabric 170 is transported along the second conveyor path 195.

[0063] In the fifth method step 225 following the fourth method step 220, the first protective film 165 is removed from the first adhesive layer 160 and preferably wound up. In this embodiment, the first protective film 165 is removed from the side facing the second textile fabric 170.

[0064] Furthermore, in the fifth method step 225, the second protective film 185 is removed from the second adhesive layer 180, preferably on the side facing the first textile fabric 150, and wound up automatically (cf. Fig. 9). The first and second protective films 165, 185 removed can be stored and wound up in the layer storage 120.

[0065] In the sixth method step 230 following the fifth method step 225 (cf. Fig. 10), downstream of the removal of the second protective film 185, preferably onto the uncovered second adhesive layer 180, for example, along a predefined laying area 325 between the openings 305, 310, 315, 320, for example by means of the robot 200, the first and second electrical cables 25, 30 are laid individually or at least partially together onto the second adhesive layer 180 and onto the second textile fabric layer to form the cable arrangement 20. The electrical cables 25, 30 can also be pre-assembled and laid as the cable arrangement 20. Furthermore, the cables 25, 30 preferably protrude into the openings 305, 310, 315, 320.

[0066] By configuring the second adhesive layer 180, preferably with a contact adhesive and / or pressure-sensitive adhesive, at least some of the electrical cables 25, 30 remain adhered to the second adhesive layer 180, so that the cable sheath 35 of the first and / or second electrical cable 25, 30 is firmly bonded to the second adhesive layer 180 and, via the second adhesive layer 180, to the second textile fabric layer 175. This prevents the cable assembly 20 from slipping during further transport.

[0067] In a seventh method step 235 following the sixth method step 230, the cable arrangement 20 is placed on the second textile fabric layer 175 and fed to the scanner 125. The scanner 125 scans the cable arrangement 20 on the second adhesive layer 180 and / or determines a path of the cable arrangement 20 on the second layer. Furthermore, the scanner 125 determines the arrangement of the cable arrangement 20 relative to the first to fourth openings 305, 310, 315, 320.

[0068] In the seventh method step 235, the scanner 125 provides information about the arrangement of the cable arrangement 20 relative to the openings 305, 310, 315, 320 to the control unit 136. For example, the scanner 125 provides at least one, preferably several, images to the control unit 136. The control unit 136 can, for example, use an image recognition algorithm to determine a position of the cable arrangement 20 relative to the openings 305, 310, 315, 320 and / or at least one path of the cable arrangement 20 on the second textile fabric 170.

[0069] Based on the determined course of the cable arrangement 20 on the second textile fabric 170 and a predefined width of the first partial region 85 and the third partial region 95, the control device 136 determines a cutting pattern 330 in the eighth method step 240. The control device 136 provides the cutting pattern 330 to the second cutting machine 135.

[0070] In the ninth method step 245 following the eighth method step 240 or carried out in parallel to the eighth method step 240 (cf. Fig. 11), the cable arrangement 20 is transported further on the second textile fabric 170. Furthermore, the first textile fabric 150 is transported to the second textile fabric 170 via the first conveyor path 190 and pressed onto the second textile fabric 170 and the cable arrangement 20 at the pressing device 130. In this case, for example, the first adhesive layer 160 comes into direct contact in the first partial area 85 and the third partial area 95 with the second adhesive layer 180 or, if the second adhesive layer 180 is not provided, into direct contact with the second textile fabric layer 175. In this case, by using a pressure-sensitive adhesive for the first and / or second adhesive layers 160, 180, a material-to-material connection is formed in the first partial area 85 and / or third partial area 95, which connects the second textile fabric layer 175 to the first textile fabric layer 155.

[0071] If the adhesive layer 160, 180 is completely omitted, the first and third partial areas 85, 95 can be connected to each other in a different way, for example. For example, a positive and / or material-locking and / or force-locking connection is possible. For example, the textile fabrics 150, 170 can be sewn and / or welded and / or riveted.

[0072] In the second partial area 90, the first textile fabric 150 with the first adhesive layer 160 is pressed directly onto the cable arrangement 20 by the pressing device 130, wherein the first adhesive layer 160 forms a materially bonded connection to the cable arrangement 20. The first textile fabric 150 and the second textile fabric 170 are aligned with each other such that the openings 305, 310, 315, 320 in the first and second textile fabric layers 150, 170 overlap (cf. Fig. 11).

[0073] By pressing the first and second textile fabrics 150, 170 together, which can be done for example by means of elastic rollers, a good mechanical connection between the first textile fabric 150 and the second textile fabric 170 as well as the first textile fabric layer 155 and the second textile fabric layer 175 to each other and each to the cable arrangement 20 is ensured.

[0074] In the tenth method step 250 following the ninth method step 245 (cf. Fig. 12), the wiring harness 10 is cut out by the second cutting machine 135 based on the cutting pattern determined by the control device 136. For example, the wiring harness 10 can be severed using a laser that penetrates the first and second textile fabric layers 155, 175.

[0075] The cut to form the cut surfaces 70, 75 is made at a distance from, essentially parallel to, the cable arrangement 20, with a predefined projection that determines the width of the first and third partial areas 85, 95. The cutting pattern 330 is further selected, for example, such that it ends at the openings 305, 310, 315, 320, thereby completely separating the first and second textile fabrics 150, 170 from a remaining textile fabric remnant 335.

[0076] In an eleventh method step 255 following the tenth method step 250, the remaining textile fabric residue 335 of the first and second textile fabric layers 155, 175 adhering to one another is disposed of.

[0077] Particularly when using textile fabric 150, 170 made of natural fibers, the interconnected textile fabric remnants 335 from the first and second textile fabric layers 155, 175 can be recycled very easily. This is particularly the case if, for example, a material is used for the adhesive layer 160, 180 that is recyclable or made from natural products.

[0078] Furthermore, the scanner 125 can easily detect a different arrangement and position of the cable arrangement 20 on the second textile fabric 170, and thus even a slight mispositioning of the cable arrangement 20 by the robot 200 can be easily compensated. This has the advantage that only minimal requirements need be placed on the laying properties of the robot 200 for positioning the cable arrangement 20 and, in particular, for laying the individual cables 25, 30 on the second textile fabric 170. As a result, the described method and the production system 100 described above are particularly suitable for the fully automated production of the cable harness 10.

[0079] Because the textile fabric layers 155, 175 protrude laterally beyond the cable assembly 20, the wiring harness 10 can be easily secured in the vehicle in the first sub-area 85 and / or third sub-area 95 using fasteners (not shown). Clips, screws, or similar fasteners are suitable, for example.

[0080] Should additional fastening openings be necessary for this purpose, these can be additionally cut into the first and / or third partial region 85, 95, for example, during the tenth method step 250. In particular, the control device 136 can thereby position the fastening openings in the transverse direction such that the fastening opening is sufficiently spaced from the first and second cut surfaces 70, 75 as well as from the cable arrangement 20.

[0081] Furthermore, the method for producing the cable harness 10 is particularly suitable for the fully automated production of cable harnesses 10.

[0082] Furthermore, the described method allows for simple, customized, and fully automated production of the wiring harness 10. This makes the wiring harness 10 particularly suitable for installation in customized vehicles or vehicles produced in small quantities. This allows the respective equipment, particularly with regard to electrical loads, to be easily taken into account during the production of the wiring harness 10, making the wiring harness 10 particularly lightweight.

[0083] In particular, it is further noted that the above-described sequence of method steps is the preferred sequence in this exemplary embodiment. Of course, it would also be possible to choose a different sequence of method steps. For example, the first openings 305 can only be introduced into the first and second textile fabrics 150, 170 once the cable arrangement 20 has already been arranged on at least the second textile fabric 170.

[0084] It would also be possible for the first and second textile fabrics 150, 170 to be unwound, cut and spread out from a common first roll 140.
