[0001] Metal strip, sealing, decorative or edge strip with a metal strip as an insert and method for its production
[0002] The present invention relates to a metal strip as an insert for sealing, decorative or edge strips, in particular for motor vehicles, with a plurality of incisions which follow one another in the direction of the longitudinal extent of the metal strip, in particular periodically, and extend transversely to the longitudinal extent of the metal strip.
[0003] Furthermore, the present invention relates to a sealing, decorative or edge strip with such a metal strip as an insert and to a method for producing such a sealing, decorative or edge strip.
[0004] Metal strips of the type mentioned above are used particularly in the automotive sector as inserts for sealing strips for sealing engine compartment, trunk, and door openings, as decorative or edge strips. The continuously manufactured metal strips are coated with rubber and / or flexible or elastic plastic as a coating material and have cuts that are at least partially open to allow the coating material to penetrate the metal strip. This improves the adhesion or anchoring between the coating material and the metal, which is very poor due to the different materials. Adhesive-coated metal strips are also available, but these are relatively expensive and their production requires a lot of energy, resulting in climate-damaging emissions in the form of CO2 and solvents.Such metal strips can be produced by cutting, particularly rotary cutting or laser cutting, with the cut strips subsequently being elongated, particularly by rolling and / or rolling stretching, to open the cuts created by the cutting. Suitable metals include, in particular, aluminum, aluminum alloys, steel, including micro-alloyed or multi-phase steel, and stainless steel.
[0005] Before or after being coated with the coating material, the metal strips are bent into a mostly U-shaped clamping profile, which is clamped onto the sealing flanges of the vehicle opening. V-shaped and S-shaped clamping profiles are also known. Due to the incisions required to anchor the coating material to the metal strip, the problem arises that the metal strips do not have sufficient strength in the longitudinal direction of the metal strip. Particularly when coating the metal strips with the coating material, which is usually done by extrusion, the strips can break or tear.
[0006] The invention is therefore based on the object of providing a metal strip of the type mentioned above that does not have this problem, or only to a lesser extent. In particular, despite the coating being well anchored to the metal strip, sufficient strength of the metal strip in its longitudinal direction should be achieved.
[0007] This object is achieved by a metal strip having the features of claim 1.
[0008] Due to the at least one uncut area across the width of the metal strip, in which there are no incisions over the entire length of the metal strip, sufficient tensile strength of the metal strip can be achieved in its longitudinal direction. Since there is at least one area with incisions in addition to the at least one uncut area, sufficient anchoring of the coating of the metal strip to the metal strip can still be guaranteed. The uncut areas can have a width of 1 mm or more, in particular 1.5 mm or more, preferably 2 mm or more. This has proven advantageous for achieving sufficient tensile strength in the longitudinal direction of the metal strip.
[0009] At least one uncut area can comprise one of the two lateral edges of the metal strip. This edge of the metal strip therefore has no incisions. According to a particular embodiment of the invention, both lateral edges of the metal strip are formed without incisions, thus having an uncut area. Alternatively or additionally, an area without incisions can be provided in a central area of the metal strip. This allows a desired tensile strength of the metal strip to be adjusted particularly well in the longitudinal direction.
[0010] The uncut areas of the metal strip can be arranged symmetrically or asymmetrically to the central longitudinal axis of the metal strip. This increases the possibilities for combining suitable tensile strength with good adhesive properties of the metal strip.
[0011] The areas with incisions in the metal strip can also be arranged symmetrically or asymmetrically to the central longitudinal axis of the metal strip in order to advantageously adjust the desired properties.
[0012] The incisions in the metal strip can have an opening width in the longitudinal direction of the metal strip of 0.1 mm to 2 mm, in particular 0.2 to 1.2 mm, preferably 0.3 to 0.9 mm. The anchoring of a coating on the metal strip can thereby be advantageously adjusted. According to a further embodiment of the invention, the metal strip is produced by relative cutting or by laser cutting followed by lengthening, in particular by rolling. This yields advantageous results for the metal strip.
[0013] According to a further embodiment of the invention, the metal strip is roughened at least in some areas, viewed in the transverse direction of the metal strip, particularly in an area with incisions. This can further improve the adhesion of a coating to the metal strip.
[0014] According to a further embodiment of the invention, the metal strip can be rolled in the uncut areas. At least one uncut area can thus have a rolling mark. The properties of the metal strip, in particular its tensile strength in the longitudinal direction of the metal strip, can thereby be advantageously influenced.
[0015] According to a further embodiment of the invention, at least two rows of consecutive incisions in the direction of the transverse extent of the metal strip are provided, wherein the incisions of the two rows are arranged alternately offset from one another in the direction of the longitudinal extent of the metal strip, so that the incisions of the two rows are not arranged at the same height when viewed in the direction of the longitudinal extent of the metal strip, and wherein the incisions of the two rows transverse to the longitudinal extent of the metal strip overlap one another at most minimally or are at most minimally spaced from one another. This results in a type of neutral fiber between the incisions of the said rows, which further increases the tensile strength of the metal strip in its longitudinal direction.According to one embodiment of the invention, the overlap of the incisions with each other is 1 mm or less, 0.8 mm or less, 0.5 mm or less, in particular 0.2 mm or less, preferably 0 mm. An overlap of this magnitude has proven particularly advantageous.
[0016] According to another embodiment of the invention, the distance between the incisions is 1 mm or less, 0.8 mm or less, 0.5 mm or less, in particular 0.2 mm or less, preferably 0 mm. This also allows an advantageous tensile strength of the metal strip to be achieved in its longitudinal direction.
[0017] According to one embodiment of the invention, the width of the incisions in the transverse direction of the metal strip is 0.5 mm to 10 mm, in particular 1 mm to 7 mm, preferably 1.5 mm to 4 mm. Particularly small incisions, which are thus made in large numbers, lead to good mechanical anchoring of the coating and to advantageous tensile strength of the metal strip in its longitudinal direction.
[0018] According to a further embodiment of the invention, in which the metal strip is produced by cutting and subsequent lengthening, the lengthening is preferably continued until a rounded shape is formed at the end(s) of the incisions located inside the strip. The resulting strip largely corresponds to a stamped strip, but is simpler and more cost-effective to produce. The incisions preferably have an opening width in the longitudinal direction of the metal strip of 0.1 mm to 2 mm, in particular 0.2 mm to 1.2 mm, preferably 0.3 mm to 0.9 mm.
[0019] The incisions of at least one of the two rows preferably end at one of the two side edges of the metal strip or at neither of the two side edges of the metal strip. This allows advantageous properties of the metal strip to be achieved with regard to its bendability and compressibility.
[0020] According to one embodiment of the invention, at least one further row of incisions is provided, wherein the incisions of at least one further row preferably open into one of the two side edges of the metal strip, or at least one further row does not open into either of the two side edges of the metal strip. This also allows advantageous properties of the metal strip to be achieved.
[0021] According to a further embodiment of the invention, which is also claimed separately, at least one row of consecutive incisions is provided in the longitudinal direction of the metal strip, the incisions being opened by lengths of the metal strip. The end regions of the incisions, viewed in the transverse direction of the metal strip, are closed again at least partially on at least one side by rolling following the opening. This also allows the tensile strength of the metal strip to be increased in the longitudinal direction. An advantageous adjustment of the bendability of the metal strip can also be achieved in this way.
[0022] According to a further development of the invention, the closed end regions of the incisions can have a length in the transverse direction of the metal strip of 0.1 mm to 10 mm, in particular 0.3 mm to 5 mm, preferably 0.5 mm to 2 mm. This allows advantageous properties of the metal strip to be achieved.
[0023] According to a further development of the invention, the rolling to close the cuts in an end region is preferably carried out with a rolling track depth of less than 0.3 mm, in particular between 0.01 mm and 0.2 mm, preferably between 0.02 mm and 0.1 mm. This also allows advantageous properties of the metal strip to be achieved, which positively influence the tensile strength in the longitudinal direction. This approach is comparable to a strip with at least one uncut region.
[0024] The metal strip according to the invention can advantageously be bent into a U-, V-, or S-shaped profile. Such profiles can be used particularly advantageously in the automotive sector.
[0025] The invention further comprises a sealing, decorative, or edge strip consisting of a metal strip of the type described above or a profile made therefrom and a coating of rubber and / or a flexible or elastic plastic, wherein the incisions in the metal strip are at least partially penetrated by the coating. Such strips can be advantageously used in the automotive sector.
[0026] It is particularly preferred that there be no bonding agent between the metal strip and the profile coating. This reduces costs and prevents environmentally harmful emissions.
[0027] According to a preferred embodiment of the invention, the metal strip is not broken in the finished strip. This advantageously maintains the tensile strength in the longitudinal direction of the metal strip.
[0028] The invention also relates to a method for producing a sealing, decorative, or edge strip of the aforementioned type, wherein the metal strip is coated without the use of an adhesion promoter. The coating is preferably carried out by extrusion. This, in turn, also allows costs to be reduced and emissions to be avoided. According to a further development of the method according to the invention, the coated strip is not broken. This, in turn, allows the tensile strength in the longitudinal direction of the metal strip to be maintained.
[0029] The metal strip is preferably produced by cutting, particularly by rotary cutting or laser cutting, and preferably by subsequent lengthening. This allows for waste-free production at high speed.
[0030] Embodiments of the invention are illustrated schematically in the drawings and are described below. They show:
[0031] Fig. 1 to 30 show a plan view (even-numbered figures) and a cross-section (odd-numbered figures) of embodiments of a metal strip according to the invention and
[0032] Fig. 31 to 40 a plan view of further embodiments of the metal strip according to the invention.
[0033] The metal strips 1 shown in the figures have a plurality of successive incisions 2 in the longitudinal direction I of the metal strip. The incisions 2 are arranged in each case in periodic succession in the longitudinal direction I of the metal strip 1 in adjacent rows 3, viewed in the transverse direction II of the metal strip 1. The incisions 2 can open into one of the two lateral edges 4 of the metal strip 1. However, incisions 2 can also be provided that do not open into either of the two lateral edges 4 of the metal strip 1. The metal strips 1 of Figures 13 to 38 are stretched so far in the longitudinal direction I of the metal strip 1 that a rounding results at the ends of the incisions 2.
[0034] 1 and 3 there are two rows 3i and 3s of incisions 2, each of which ends in a lateral edge 4 of the metal strip 1. In addition, there are three rows 32, 3a and 34 of incisions 2 that do not end in either of the two lateral edges 4 of the metal strip 1. Between the incisions 2 that do not end in a lateral edge 4 of the metal strip 1 and the incisions 2 that end in an edge 4 of the metal strip 1 there is an uncut area 5. In Fig. 1 these two uncut areas 5 are not rolled, whereas in the metal strip of Fig. 3 they are rolled, so that a rolling track 12 can be seen in each case. The incisions 2 that do not end in one of the two edges 4 of the metal strip 1 overlap with one another as viewed in the transverse direction II of the metal strip 1.
[0035] The metal strip of Fig. 5 largely corresponds to the metal strip of Fig. 3. However, the metal strip has a surface roughening 7 in the area of the incisions that do not open into one of the two side edges 4 of the metal strip 1, while such a roughening is not present in the metal strip of Fig. 3.
[0036] 7 and 8 has no incisions in the area of its two side edges 4. In the area between the two side edges 4 of the metal strip 1, there are nine rows 3 of incisions 2 which do not open into either of the side edges 4 of the metal strip and which overlap one another when viewed in the transverse direction II of the metal strip 1. The uncut areas 5 of the metal strip 1 are again rolled here, i.e., have a rolling mark 12. The metal strip of Figs. 9 and 10 corresponds to the metal strip of Figs. 7 and 8, but does not have a rolling mark 12. In the metal strip of Figs. 11 and 12, in addition to the two uncut areas 5 in the area of the two side edges 4 of the metal strip 1 in Figs. 7 and 8, there is also an uncut area 5 in the middle of the metal strip 1. The uncut areas 5 each have a rolling mark 12.
[0037] The metal strip of Figs. 13 and 14 largely corresponds to the metal strip of Figs. 3 and 4. However, the incisions 2 that do not terminate in a side edge 4 of the metal strip 1 do not overlap with each other in the metal strip 1 of Figs. 13 and 14. They are also not spaced apart, but rather form a neutral fiber 6 between them.
[0038] The metal strip of Figs. 15 and 16 largely corresponds to the metal strip of Figs. 13 and 14. However, the metal strip of Figs. 15 and 16 has a surface roughening 7 in the area of the incisions 2 that do not open into one of the two side edges 4 of the metal strip 1, while such a roughening is not present in the metal strip of Figs. 13 and 14.
[0039] The metal strips of Figs. 17 to 20 largely correspond to the metal strip of Figs. 15 and 16. However, the uncut regions 5 are arranged asymmetrically to the longitudinal center III of the metal strip 1 and also have a different width B in the transverse direction II of the metal strip 1.
[0040] 21 to 24 largely correspond to the metal strips in Fig. 7 to 10. In contrast to these metal strips, however, the incisions 2 do not overlap with one another when viewed in the transverse direction II of the metal strip 1. Rather, they each form a neutral fiber 6 between them. The metal strips 1 in Fig. 21 to 24 can be designed with or without surface roughening 7 in the region of the incisions 2. The metal strip 1 in Fig. 25 and 26 largely corresponds to the metal strip in Fig. 11 and 12. Here, too, the difference is that the incisions 2 do not overlap with one another when viewed in the transverse direction II of the metal strip 1, but rather form a neutral fiber 6 between them. The metal strips 1 in Fig. 25 and 26 can also be designed with or without surface roughening 7 in the region of the incisions 2.
[0041] The metal band of Fig. 27 and 28 corresponds to the metal band 1 of Fig. 25 and
[0042] 26 largely corresponds. In contrast to that, the metal band 1 of Fig.
[0043] 27 and 28, however, do not show rolling track 12.
[0044] 29 and 30, an uncut region 5 is present in the area of one lateral edge 4, while in the area of the other lateral edge 4 there are incisions 2 leading into this region. The end of these incisions 2 on the inside of the strip is adjoined by a further uncut region 5. Between the two uncut regions 5 there are eight rows of incisions 2 which do not lead into either of the lateral edges 4. These incisions 2 do not overlap with one another as viewed in the transverse direction II of the metal strip 1. The uncut regions 5 each have a rolling track 12. The metal strip 1 of Figs. 29 and 30 can be designed with or without surface roughening 7 in the area of the incisions 2.
[0045] The metal strip of Fig. 31 largely corresponds to the metal strip of Fig. 13. In contrast to this metal strip, the two uncut areas 5 are so small that these two uncut areas 5 can be equated with a neutral fiber 6. In this embodiment, there is only one row 3 of central incisions 2, which do not open into either of the side edges 4. The area of these incisions 2 can be designed with or without surface roughening 7. The metal strips of Figs. 32 and 33 have two uncut areas 5 in the central area of the metal strip 1. There are two rows of incisions 2, each of which opens into a side edge 4 of the metal strip. Between the two uncut areas 5 there are five further rows of incisions 2, which do not open into either of the side edges and do not overlap with each other when viewed in the transverse direction II of the metal strip 1.In the metal strip of Fig. 32, the uncut areas 5 are provided with a rolling track 12, whereas in the metal strip 1 of Fig. 33, this is not the case. The metal strip 1 of Fig. 32 and Fig. 33 can be designed with or without surface roughening 7 in the area of the central incisions 2.
[0046] In the metal strip of Fig. 34, three uncut regions 5 are present, one uncut region 5 being located in the region of a side edge 4 of the metal strip and the two other uncut regions 5 being located in the central region of the metal strip 1. Further incisions 2 open into the other side edge 4 of the metal strip 1. The uncut regions 5 each have a rolling track 12. Between the uncut regions 5, there are three rows of incisions 2 which do not open into any side edge 4 of the metal strip 1 and which, viewed in the transverse direction II of the metal strip 1, do not overlap with one another and are also not spaced from one another.
[0047] The metal strip of Fig. 35 has two uncut regions 5, one of which is located in the region of a lateral edge 4, while incisions 2 open into the other lateral edge 4. Between the two uncut regions 5 there are eight rows of incisions 2 which do not open into either of the two lateral edges 4 of the metal strip 1 and which, viewed in the transverse direction II of the metal strip 1, do not overlap with one another and are not spaced from one another. The uncut regions 5 are in turn each provided with a rolling track 12. The metal strip of Fig. 36 largely corresponds to the metal strip of Fig. 35. However, between the two uncut regions 5 there are eleven rows of incisions 2 which do not open into either of the two lateral edges 4 of the metal strip and which, viewed in the transverse direction II of the metal strip 1, do not overlap with one another and are not spaced from one another.In addition, the uncut areas 5 of this metal strip do not show any rolling marks.
[0048] The metal strip of Fig. 37 largely corresponds to the metal strip of Fig. 11 and 12. However, the incisions 2, viewed in the transverse direction II of the metal strip 1, do not overlap with each other and are not spaced apart, but each have a neutral fiber 6 between them.
[0049] The metal strip of Fig. 38 largely corresponds to the metal strip of Figs. 7 and 8. Here, too, the difference is that the incisions 2, viewed in the transverse direction II of the metal strip 1, do not overlap with each other and are not spaced apart from each other, but form a neutral fiber 6 between them.
[0050] The metal strips of Fig. 34 and 35, as well as 37 and 38 can be designed with or without surface roughening 7 in the area of the incisions 2.
[0051] The metal strip of Fig. 39 has two rows 3i and 3s of incisions 2, each of which ends in a side edge 4 of the metal strip 1. On the inside of each of these two rows 3i and 3s, there is an uncut area 5. Between the two uncut areas 5 are three rows 32, 3a, and 34 of incisions 2, which end in one of the two side edges of the metal strip 1. The incisions 2 are each widened by lengths of the metal strip 1. The special feature of the metal strip of Fig. 39 is that the end regions 13 of the incisions 2, viewed in the transverse direction III of the metal strip 1, have been at least partially closed again by rolling. Thus, between each two adjacent rows 3 of incisions 2, there is a rolling track 12.
[0052] In the metal strip of Fig. 40, the end regions 13 of the incisions 2 are also partially closed by rolling. In contrast to the metal strip of Fig. 39, however, there are only three rows 3 of incisions 2, which do not terminate in any lateral edge 4 of the metal strip. Instead, there are uncut regions 5 in the area of the two lateral edges of the metal strip 1.
