Abstract

The invention relates to a band assembly (100) comprising a profiled plastic band (101), which includes a locking recess (103) for receiving a fixing rib for a water tank cover, and a one-piece protective plastic band (104) that can be mechanically locked to the locking recess (103) in a removable manner. Preferably, the profiled plastic band (101) is mechanically deformable and can be loaded without deforming the cross-section of the locking recess (103) in the process, and the locking recess (103) or the profiled plastic band (101) remains as intact as possible during assembly, transport, and / or storage.According to the invention, a first and second strip section (100a, 100b) are provided. The profiled plastic strip (101) is designed to extend only within the first strip section (100a), and the protective plastic strip (104) is designed to extend within both strip sections (100a, 100b) and lock with the locking recess (103) at least in certain places along the profiled plastic strip (101). Therefore, the protective plastic strip (104) protrudes and can be removed without tools without damaging the locking recess (103) or the profiled plastic strip (101) during the process. At the same time, the protective plastic strip (104) protects the assembly until immediately before final assembly.

Description

Technical field

[0001] The present invention relates to a strip arrangement and a method for its manufacture. State of the art

[0002] Plastic profile strips for attaching a vehicle water box cover to a vehicle windshield are known. These plastic profile strips include a locking recess for receiving a mounting rib of the water box cover, the locking recess being designed for a force-fit and / or form-fit engagement of the mounting rib.

[0003] During the manufacturing and installation of the plastic profile strip on the windshield, it can be subjected to very high mechanical stresses. These can include, for example, bending operations to adapt the plastic profile strip to various windshield contours. Very high forces can also occur along the plastic profile strip when pressing it against the windshield edge, especially along the locking recess. Therefore, a one-piece plastic protective strip can be provided, which can be mechanically detachably locked into the locking recess and, once locked, serves to protect the recess.

[0004] Furthermore, the plastic profile strip is often attached to the windshield even before installation, particularly at the windshield manufacturer. Due to their brittleness, such pre-assembled windshields are typically transported upright. The plastic profile strip can serve as a support edge in this process. The weight of the windshield can cause the plastic profile strip, and consequently its locking recess, to deform, potentially leading to problems and / or leaks when the cowl cover is later snapped into place. Here, too, the plastic protective strip plays a crucial role in protecting the plastic profile strip and / or the locking recess.

[0005] Overall, the plastic protective strip helps protect the geometry of the cross-section of the plastic profile strip and / or the locking recess, even under the most adverse external conditions. This ensures that the water tank cover can always be reliably, precisely, and tightly locked into the locking recess of the plastic profile strip. However, before the water tank cover can be locked into the recess, the plastic protective strip must be removed. The problem here is that, due to the mechanically very stable locking mechanism, the plastic protective strip cannot be removed ergonomically and is difficult to remove from the locking recess of the plastic profile strip. The removal process therefore takes varying amounts of time and is very tiring for the worker's hand muscles over time.The cycle time on the production line must be set to the worst-case scenario, which negatively impacts the overall efficiency of the assembly process. Furthermore, removing the plastic protective strip regularly results in damage to the plastic profile strip and surrounding vehicle components or surfaces (e.g., the paintwork), for example, due to the use of unsuitable tools such as screwdrivers, pliers, or similar implements. Finally, there is a risk of injury to the person performing the task, such as breaking a fingernail, if they attempt to pry the plastic protective strip out of its retaining recess using a fingernail.

[0006] To address this, patent application EP 2 253 556 A1 proposes providing a plastic protective strip with a grip tab that extends transversely and section by section along the plastic protective strip while it is locked into the locking recess of the plastic profile strip. Such designs can easily tear, and there is a risk of slipping when gripping the tab, especially when wearing gloves or under other adverse environmental conditions, as is common in vehicle manufacturing, e.g., with oily or dirty hands. A similar approach is pursued in patent application WO2014 / 041279A1. Particularly if the grip is a wire-shaped loop for pulling out the locked plastic protective strip, this poses a high risk of injury, as the wire can cut the worker's skin depending on the force required.Both solutions also require significant additional effort in the manufacture of the strip assembly and can lead to the entire strip assembly becoming caught on another component during handling (e.g., transport, assembly, storage, etc.), causing the plastic protective strip to be unintentionally and prematurely released from the locking recess or even resulting in deformation or damage to the entire assembly and / or surrounding components. Disclosure WO 2018 / 171972 A1 discloses a protruding plastic protective strip.

[0007] Therefore, an alternative strip arrangement is desirable which overcomes the described disadvantages of the prior art and by means of which the plastic protective strip can be removed from the locking recess without tools, whereby the strip arrangement should also be as inexpensive to manufacture as possible. Brief description of the invention

[0008] According to the invention, a strip arrangement according to claim 1 and a method for manufacturing a strip arrangement according to claim 8 are proposed. Additionally, a windshield with a strip arrangement according to the invention is recommended, and a vehicle with such a windshield is provided.

[0009] To realize the strip arrangement according to the invention, a one-piece plastic profile strip is provided, which is preferably made from an extruded first plastic strand (profile strip strand, strand section). The plastic profile strip includes a locking recess that extends along the plastic profile strip. Furthermore, to realize the strip arrangement, a one-piece plastic protective strip is provided, which is preferably made from an extruded second plastic strand (protective strip strand, strand section). The cross-sections of the plastic profile strip and the locking recess are preferably designed to correspond to each other, so that a friction-fit and / or form-fit locking mechanism can be achieved.

[0010] A water tank cover with a mounting rib having a cross-section substantially corresponding to the locking recess of the plastic profile strip can preferably be installed in the locking recess with less force than it can be removed. This can be achieved, for example, by means of flexible and / or protruding plastic lips and / or locking lugs extending along the locking recess and preferably produced by co-extrusion (i.e., combining similar or different plastic melts before exiting the profile die of the extruder), the Shore hardness of which may preferably be lower than that of the locking recess.

[0011] According to the invention, a first and a second strip section are provided, wherein the plastic profile strip is designed such that it extends exclusively within the first strip section and wherein the plastic protective strip is designed such that it extends, preferably exclusively, within both strip sections and is locked into the locking recess along the, preferably entire, length of the plastic profile strip, at least section by section.

[0012] Both strip sections can be directly adjacent to each other, so that the end of the first strip section immediately coincides with the beginning of the second strip section, and / or that the end of the first strip section coincides with the beginning of the second strip section. The second strip section can extend in space as a continuation of the longitudinal direction of the first strip section or extend in space at an angle perpendicular to the longitudinal direction of the first strip section.

[0013] The length of the plastic protective strip can be longer than the length of the plastic profile strip, so that the resulting excess length of the plastic protective strip is outside the technical tolerance limits of the manufacturing process and / or corresponds to a fraction of the plastic profile strip length. The excess length of the plastic protective strip can be dimensioned such that it is manually graspable by a worker. The excess length can roughly correspond to the finger thickness of an average adult, so that the plastic protective strip can, for example, be pinched between the index finger and thumb and thus grasped. The surface of the plastic protective strip can be designed in such a way that the worker does not slip when grasping the excess length, for example, by means of a surface roughening extending along the plastic protective strip and / or by means of a rubber coating.

[0014] Due to the leverage effect present when gripping, the forces required to manually release the plastic protective strip from the locking recess can be easily overcome. Furthermore, the strip assembly can be manufactured from continuous strands, preferably extruded, without additional components or assembly steps.

[0015] Advantageous embodiments are the subject of the dependent claims and the following description. Advantages of the invention

[0016] The invention enables, on the one hand, the inner walls of the locking recess and / or the opposing edges of the locking recess to be supported against each other when the plastic protective strip is locked in place. This prevents deformation of the cross-section of the locking recess when an external force is applied to the strip assembly along the locking recess. The strip assembly can therefore be processed (e.g., deformed), further processed (e.g., pressed against a windshield edge), or transported (e.g., pre-assembled on the edge of a windshield) during or immediately after its manufacture.

[0017] The invention additionally enables the plastic protective strip to be removed manually or (semi-)automatically from the locking recess before the final assembly of the water box, with minimal time expenditure. Thus, the locking recess is optimally protected in any conceivable spatial position or arrangement until final assembly on the vehicle. The plastic protective strip is preferably removed manually and entirely without tools, by a worker grasping the plastic protective strip in the area of ​​the second section of the strip, for example, with their index finger and thumb, and pulling it out of the locking recess. This improves overall ergonomics and reduces the physical strain on the worker, as it is less tiring for the hand muscles. The risk of injury to the worker is virtually eliminated because they are no longer tempted to, for example,The plastic protective strip can be removed with a fingernail, and no other sharp-edged tools are needed. Auxiliary grips, such as wire loops or other loops, threaded into the strip arrangement between the plastic protective strip and the locking recess during manufacturing are no longer necessary.

[0018] This also minimizes the risk of assembly-related damage to the bodywork and / or the locking mechanism. Overall, this reduces assembly costs and prevents potential complaints. In the mass production of trim strips and vehicles, significant cost savings can be achieved because the duration of the "pulling out the plastic protective strip" step is now more predictable. The cycle time on the production line can be preset accordingly. In fact, the time required to remove the plastic protective strip from the locking mechanism is now negligible. A gripping device is now available for semi- or fully automated removal of the plastic protective strip, which can be easily grasped, for example, by a robot.

[0019] Advantageously, a second plastic profile strip with a locking recess is provided such that it extends exclusively within the second strip section, with the plastic protective strip additionally locking into the locking recess of this second plastic profile strip, at least partially. This increases the gripping surface of the protruding plastic protective strip and improves the grip when removing the plastic protective strip from the locking recess of the first plastic profile strip.

[0020] It is particularly advantageous if the plastic profile strip includes a contact surface for alignment along a windshield edge. Preferably, a double-sided adhesive tape is provided, comprising a first adhesive surface and a second adhesive surface covered by a protective film, preferably a single piece. The adhesive tape is advantageously applied to the contact surface via the first adhesive surface, and the protective film preferably extends within both sections of the strip.

[0021] The adhesive tape protective film can be longer than the plastic profile strip length, so that the resulting excess length of the adhesive tape protective film lies outside the technical tolerance limits of the manufacturing process and / or corresponds to a fraction of the plastic profile strip length. The resulting excess length of the adhesive tape protective film is dimensioned at least such that it can be grasped manually by a worker. The excess length can correspond approximately to the finger thickness of an average adult, so that the adhesive tape protective film can, for example, be pinched between the person's index finger and thumb and thus grasped. Preferably, within the usual manufacturing tolerance limits, the excess length is essentially identical to the excess length of the plastic protective strip.The surface of the adhesive tape's protective film can be designed in such a way that the worker does not slip when gripping the excess length, for example by means of a surface roughening and / or by means of a rubber coating.

[0022] The contact surface can simplify the assembly process, for example, while the plastic profile strip is being molded to and / or positioned against the windshield edge. The contact surface preferably serves as a guide when molding the plastic profile strip to the windshield edge, as long as the adhesive tape's protective film is in place on the second adhesive surface. Once the plastic profile strip has assumed the desired shape, the adhesive tape's protective film can be removed from the contact surface just as easily and efficiently, and with the same advantages, as the plastic profile strip can be removed from its recess. It even becomes possible to remove the plastic profile strip from the plastic profile strip simultaneously with the adhesive tape's protective film, i.e., in a single operation.However, it is preferable to first remove the adhesive tape protective film, then apply the plastic profile strip to the edge of the window, and only then remove the plastic protective strip from the locking recess.

[0023] Advantageously, one end of the plastic profile strip features a predetermined breaking point or a punched interface, essentially perpendicular to its longitudinal extent. Punching allows the plastic profile strip to be easily positioned within the predefined strip sections and is cost-effective, as the punching process can be easily integrated into the manufacturing process. A predetermined breaking point allows the strip arrangement to be adjusted later, for example, during the vehicle assembly process. In the latter case, in addition to the locking recess, the plastic protective strip is also protected from damage because it remains at least partially enclosed and guided by both locking recesses of the two plastic profile strips connected by the predetermined breaking point.

[0024] Preferably, the plastic profile strip comprises a core extending along the plastic profile strip and being plastically deformable at least in sections. The plastic profile strip is at least partially curved and ideally pre-bent to correspond to the windshield edge, preferably by means of a straight and / or oblique bend. A springback compensation is also preferably provided. This makes it easier to adapt, attach, and mount the plastic profile strip to the edge to be applied, thus speeding up the installation process. The profile strip core can be made in one piece or in multiple pieces, and can be made of metal or plastic. This plastic can differ from the plastic material of the profile strip containing the core with regard to Shore hardness and / or the material used.The profile strip core and the surrounding profile strip plastic can be produced using a co-extrusion process.

[0025] A windshield with a strip arrangement according to the invention, preferably pre-mounted on the windshield, is very well suited for the spare parts business, especially for suppliers specializing in windshield replacement. Such suppliers receive windshields from a wide variety of manufacturers, and these windshields occasionally need to be stored temporarily. In this case, the pre-mounted strip arrangement protects the longitudinal edge of the windshield during storage, transport, and / or installation. Furthermore, the still-engaged plastic protective strip protects the locking recess of the plastic profile strip from crushing caused by the windshield's own weight acting on the strip arrangement during storage.

[0026] Once the windshield is securely attached to the vehicle, the installer uses the protruding plastic protective strip as a grip to remove the entire strip from its locking recess. The installer can then lock the cowl cover's mounting rib into the recess. Thanks to the recess's design, as mentioned above, this process is particularly easy and requires minimal effort.

[0027] The inventive method enables a particularly cost-effective and efficient production of the inventive strip arrangement from single-piece strands, which are realized using plastics, preferably extruded and / or printed using a 3D printing process, and which are already joined together during the manufacturing process, e.g., by means of an interlocking mechanism. The sequence of the process steps is not determined by the sequence of the following description or the claims and can be varied within the scope of the claimed teaching.

[0028] The inventive method for producing a strip arrangement according to the invention comprises at least the following process steps: Provision of a profile strip string with a locking recess for receiving a fastening rib of a water box cover and a protective strip string which is mechanically detachable at least in sections with the locking recess, and division of the profile strip string into two parts in a machining area, wherein the protective strip string remains in one piece.

[0029] In a further development of the method, a strand section is separated from the profile strip strand and the protective strip strand before or after the splitting of the profile strip strand into two; this strand section comprises the processing area. The strand section is preferably formed from or includes the end sections of the profile strip strand and the protective strip strand. This strand section forms the basis of the strip arrangement.

[0030] In the processing area described here with regard to the method, the division into two parts creates a boundary or a transition area between the two strip sections described with reference to the strip arrangement according to the invention.

[0031] The splitting can occur before or after the production of a strand section, increasing flexibility and allowing for application-specific responses to customer requirements. The splitting can be achieved using a predetermined breaking point, enabling subsequent or delayed separation of the material. In this case, separation would only be possible after production and before, during, or after assembly. Alternatively or additionally, the splitting can be achieved by punching or cutting, which can be easily and preferably automatically integrated into the production process. This results in a material separation, cutting off a terminal section from the profile strip strand, which can optionally be removed from both the profile strip strand and the protective strip strand.The terminal section described here in relation to the method corresponds to or forms the second plastic profile strip described in relation to the strip arrangement according to the invention.

[0032] Preferably, a profile knife is used for punching, which is designed such that it at least partially recesses the protective strip strand or the plastic protective strip resulting from the protective strip strand, so that it remains intact or is at least not completely cut through. The profile knife is preferably designed to correspond to the cross-section of the profile strip strand or strand section or the plastic profile strip and preferably includes a recess for the cross-section of the protective strip strand or the plastic protective strip. Furthermore, the advantages of the method according to the invention correspond to the advantages explained above with regard to the strip arrangement according to the invention and the embodiments and variants mentioned in this context. Reference is therefore also made to this foregoing description with regard to the method according to the invention.Further advantages and embodiments of the invention will become apparent from the following description of the figures and the underlying drawings.

[0033] It is understood that the features mentioned above and already stated, as well as those to be explained below, may appear in the drawings not only in the combination of features specified, but also in other combinations not explicitly mentioned here, or individually or in isolation, without departing from the scope of the present invention. This applies in particular to all features shown and / or described in the various embodiments merely for the sake of completeness, which are not essential to the invention, i.e., not absolutely necessary to achieve the effects according to the invention.

[0034] The invention is subsequently illustrated schematically in the drawings with reference to the following exemplary embodiments and briefly described with reference to the drawings. Identical or equivalent features are designated with the same reference numerals unless otherwise specified. Brief description of the drawings

Figure 3 shows an end piece of the machined strip arrangement made of Figure 2 . Figure 4 shows a second strip arrangement processed according to the invention. Figure 5 shows the cross-section of the strip arrangement according to the invention. Figure 6 shows a windshield with a strip arrangement according to the invention. Figure 7 shows to Figure 5 an alternative embodiment for the cross-section. Detailed description of the drawings

[0036] Figure 1Figure 1 shows a one-piece, extruded and / or 3D-printed profile strip 100d made of at least one plastic. The profile strip 100d comprises a contact surface 102, preferably continuous, and a locking recess 103. A protective strip 104a, corresponding to the locking recess 103, is inserted into the locking recess in a form-fitting and / or force-fit manner. The protective strip 104a is also manufactured in one piece from a plastic, preferably by extrusion and / or 3D printing. A double-sided adhesive tape (not visible) is applied to the contact surface 102. The second adhesive side of the double-sided adhesive tape, which is not bonded to the contact surface 102, is covered with a protective film 105. The end sections of the profile strip strand 100d and the protective strip strand 104a form a strand section 100c, which forms the basis of the strip arrangement 100.The strand section can be separated from the profile strip strand 100d and the protective strip strand 104a by means of a punching and / or a cutting process.

[0037] Generally, thermoplastics and / or thermosets with and / or without fillers and / or in a wide range of Shore hardnesses are suitable plastics. Examples include PE (polyethylene), PP (polypropylene), PA6 (polyamide 6), PA12 (polyamide 12), PA6.6 (polyamide 6.6), ABS (acrylonitrile butadiene styrene), PVC (polyvinyl chloride), PVC / ABS, SAN (styrene / acrylonitrile), PC (polycarbonate), PMMA (polymethyl methacrylate), and others.

[0038] Figure 2 shows the Figure 1The known strand section 100c, which has been treated according to the invention, is used to create a strip arrangement 100 with a first and a second strip section 100a, 100b. In this embodiment, the plastic profile strip 101, with its enclosed locking recess 103 and contact surface 102 (largely covered by the double-sided adhesive tape 106 with adhesive tape protective film 105), extends exclusively within the first strip section 100a and within the usual manufacturing tolerances. In this embodiment, the plastic protective strip 104 extends exclusively within both strip sections 100a, 100b and along, preferably its entire length, the plastic profile strip 101 and is positively locked and releasably engaged with the locking recess 103, at least in sections.

[0039] In the preferred embodiment shown here, the plastic profile strip 101 extends in one piece and continuously from the beginning to the end of the first strip section 100a, and the plastic protective strip 104 extends in one piece and continuously from the beginning of the first strip section 100a to the end of the second strip section 100b. The plastic protective strip 104 thus bridges the boundary between the two strip sections 100a and 100b in one piece and continuously. In the area of ​​the second strip section 100b, the plastic protective strip 104 runs at least partially freely and / or without the guidance of a locking recess. Therefore, in the second strip section 100b, the plastic protective strip 104 is not, at least partially, surrounded by the plastic material of a locking recess and / or a plastic profile strip.The plastic protective strip 104 may preferably protrude at one end of the plastic profile strip 101, wherein this protruding section lies significantly outside the technical tolerance limits of the manufacturing process, at least such that the protruding section acts as a handle by means of which the plastic protective strip 104 can preferably be manually released from the locking recess of the plastic profile strip 101.

[0040] In a further advantageous embodiment of this design (not shown in this figure), the aforementioned double-sided adhesive tape 106 and / or the adhesive tape protective film 105 extends in one piece and continuously from the beginning of the first strip section 100a to the end of the second strip section 100b. The double-sided adhesive tape 106 and / or the adhesive tape protective film 105 thus bridges the transition area (or boundary) 110 between the two strip sections 100a and 100b in one piece and continuously. In the area of ​​the second strip section 100b, the double-sided adhesive tape 106 and / or the adhesive tape protective film 105 runs at least partially free of a contact surface. Therefore, in the second strip section 100b, the double-sided adhesive tape 106 and / or the adhesive tape protective film 105 is not arranged on a contact surface, at least partially.The double-sided adhesive tape 106 and / or the adhesive tape protective film 105 preferably protrudes at one end of the plastic profile strip 101, this protruding section being significantly outside the technical tolerance limits of the manufacturing process, at least such that the protruding section acts as a handle by means of which the adhesive tape protective film 105 can be detached from the adhesive tape 106 along the strip arrangement 101. Preferably, the protruding section is also free of double-sided adhesive tape 106 and comprises at least partially exclusively the adhesive tape protective film 105.In this case, the aforementioned double-sided adhesive tape 106 extends in one piece and continuously from the beginning of the first strip section 100a to the end of the first strip section 100a, and the adhesive tape protective film 105 extends simultaneously in one piece and continuously from the beginning of the first strip section 100a to the end of the second strip section 100b. A material interruption 108 of the plastic profile strip material at the end of the first strip section 100a is also shown.

[0041] Figure 3 The protruding plastic protective strip 104 shows the one from the Figure 2The known strip arrangement 100 is shown in perspective detail. Also easily recognizable is the strip section 100a with a plastic profile strip 101, a contact surface 102, a locking recess 103, the plastic protective strip 104, a double-sided adhesive tape 106, an adhesive tape protective film 105, and a profile strip core 107, preferably made of metal. The profile strip core 107 is preferably provided additionally and can, for example, comprise aluminum and be designed in multiple parts, as shown in the image. The locking recess 103 has an approximately U-shaped cross-section and comprises two locking hooks extending at least partially along the locking recess 103 and preferably opposing each other. The plastic protective strip 104 has an approximately T-shaped cross-section and is shaped such that the plastic protective strip 104 can be positively locked to the locking hooks, at least partially. Figure 3The arrangement is shown already locked in place. The cross-sectional area shown, which represents the end section of the plastic profile strip 101, can be realized by means of a predetermined breaking point 108, by means of a punching 108 or by means of a material cut 108.

[0042] Figure 4 shows the Figure 1The known strand section 100c is used as an intermediate product, which has been pretreated according to the invention, resulting in a strip arrangement 100 with a first and a second strip section 100a, 100b. In the preferred embodiment shown here, a (first) plastic profile strip 101 is shown with a locking recess 103 encompassed by it (not visible in the image) and a contact surface 102 (mostly covered by the double-sided adhesive tape 106 with adhesive tape protective film 105). The first plastic profile strip 101 extends exclusively within the first strip section 100a and within the limits of the manufacturing-specific tolerances.The preferably similarly designed second plastic profile strip 101', with a locking recess 103' encompassed by it and a contact surface 102' (largely concealed by the double-sided adhesive tape 106' with adhesive tape protective film 105), extends exclusively and within the manufacturing-specific tolerance limits within the second strip section 100b. The adhesive tape 106, 106' with the adhesive tape protective film 105 preferably extends continuously and in one piece within both strip sections 100a, 100b along and over both plastic profile strips 101, 101' and is bonded at least partially to the contact surfaces 102, 102' of both plastic profile strips 101, 101'.

[0043] The plastic protective strip 104 extends in one piece and continuously within both strip sections 100a, 100b along and over both plastic profile strips 101, 101' and is at least partially locked to the locking recesses 103, 103' of both plastic profile strips 101, 101' in a form-fitting and / or force-fitting and releasable manner.

[0044] In the preferred embodiment shown here, the first plastic profile strip 101 extends in one piece and continuously from the beginning to the end of the first strip section 100a. The second plastic profile strip 101' preferably extends in one piece and continuously from the beginning to the end of the second strip section 100b. The plastic protective strip 104 extends, preferably in one piece and continuously, from the beginning of the first strip section 100a to the end of the second strip section 100b. In all embodiments, the plastic protective strip 104 bridges the transition area 110 in one piece and continuously, within which both strip sections 100a and 100b abut each other.

[0045] In the preferred embodiment shown here, the plastic protective strip 104 runs in the area of ​​the second strip section 100b, in contrast to the one shown in Figure 2The known arrangement is present, but no longer free. The plastic protective strip 104 is at least partially surrounded by the locking recess 103' of the second plastic profile strip 101'. This protruding arrangement, which, from the perspective of strip section 100a, lies clearly outside the technical tolerance limits of the manufacturing process and comprises the second plastic profile strip 101' with locking recess 103' and the plastic protective strip 104, now functions as a handle by means of which the plastic protective strip 104 can be easily manually detached along the locking recess 103 of the plastic profile strip 101.

[0046] In a further advantageous embodiment, the aforementioned double-sided adhesive tape 106 and / or the adhesive tape protective film 105 extends in one piece and continuously from the beginning of the first strip section 100a to the end of the second strip section 100b. The double-sided adhesive tape 106, 106' and / or the adhesive tape protective film 105 thus bridges the transition 110 between the two strip sections 100a and 100b in one piece and continuously. The double-sided adhesive tape 106, 106' and / or the adhesive tape protective film 105 thus bridges the boundary between the two strip sections 100a and 100b in one piece and continuously. In contrast to the above, the double-sided adhesive tape 106' and / or the adhesive tape protective film 105 runs in the area of ​​the second strip section 100b. Figure 2The aforementioned expedient further development of the arrangement shown there is no longer free. The double-sided adhesive tape 106' is therefore at least partially adhered to the contact surface 102' of the plastic profile strip 101'. This protruding arrangement, which, from the perspective of the strip section 100a, lies clearly outside the technical tolerance limits of the manufacturing process, and comprises the second plastic profile strip 101' with locking recess 103' and the plastic protective strip 104 and the double-sided adhesive tape 106' with adhesive tape protective film 105, now functions as a handle by means of which the plastic protective strip 104 and / or the adhesive tape protective film 105 can be easily removed manually along the locking recess 103 or the contact surface 102 of the plastic profile strip 101.The double-sided adhesive tape 106, 106' is preferably cut in the transition area 110 between the two strip sections 100a, 100b, so that only the adhesive tape protective film 105 remains in one piece and two adhesive tape sections adjoin the transition area 110. The transition area 110 can be realized by means of a predetermined breaking point 108, a punching 108, or a material cut 108. A profile strip core 107, 107' can preferably be provided on both sides and adjacent to the transition area 110 and may, for example, comprise aluminum, be multi-part, and / or be provided at different positions on the cross-section.

[0047] Figure 5 The cross-section of the strip arrangement 100 is shown. This cross-section describes the cross-section of strip section 100a, which is located in the Figure 2 shown strip arrangement 100 and the cross-sections of the strip sections 100a and 100b of the in the Figure 4shown strip arrangement 100.

[0048] The following components are shown in detail: the one-piece plastic protective strip 104, the plastic profile strip 101, 101', a free section of the contact surface 102, 102', the locking recess 103, 103', the double-sided adhesive tape 106, 106', the adhesive tape protective film 105, and a profile strip core 107, 107'.

A contact surface with double-sided adhesive tape for attaching the assembly along the windshield edge can be omitted here or is replaced by the mounting groove 109, 109'. Apart from this, all other features of the invention are also implemented here and are characterized by identical reference numerals. For further details, please refer to the description.

[0054] In all embodiments described and / or shown above, the plastic profile strip 101, 101' can be made of different materials. In particular, sections extending along a body opening and / or a vehicle window are preferably made, at least partially and / or in certain areas, of a plastic with a lower Shore hardness compared to the Shore hardness of the plastic profile strip 101, 101' and / or compared to the Shore hardness of the locking recess 103, 103'. The embodiments shown can preferably be manufactured by a co-extrusion process. Alternatively, a 3D printing process or the simultaneous use of both manufacturing processes would also be conceivable. Other processes, which preferably allow for the one-piece production of the strip assembly components as a continuous strand, are also applicable and recommended. List of reference symbols
