    The invention relates to a method for the production of a metal strip, in which a metal strip is provided which comprises at least two parts welded together at a weld seam. The invention also relates to a metal band which is produced by a method of the type mentioned. Finally, the invention also relates to a device for the production of a metal strip which has at least two parts welded to one another at a weld seam, encompassing two rollers or two flanges for holding and moving the metal strip.
    Basically, methods and apparatus for grinding welded metal strips of the prior art are known. Such metal tapes are manufactured for certain applications with a very high surface quality and are usually polished or even polished. The metal strips are used, for example, for the production of plate-shaped or film-like materials, in particular for films for photography, LCD screens or for "Engineered Stone". In this case, a liquid or pasty material is applied to a driven / moving belt and the at least partially solidified material lifted. The surface quality of the product produced with such a metal tape depends directly on the surface quality of the metal strip.
    In order to allow correspondingly wide belts for the efficient production of the above-mentioned products, individual sheet metal webs often have to be joined by welding, for example when these sheets are not manufactured by a steel producer in the required width.
    An object of the invention is therefore to improve the grinding of a weld on ei¬nem metal strip, or produce an improved metal strip. In particular, the weld produced during the joining of the metal strips should, as far as possible, be ground so that a homogeneous strip surface is produced in order to be able to meet the above requirements.
    This object is achieved by a method of the type mentioned in the introduction, in which the weld is transversely transverse to its longitudinal direction and the weld is then longitudinally ground in the longitudinal direction thereof.
    The object of the invention is also achieved with a metal strip made by a method of the above mentioned kind.
    Finally, the object of the invention is also achieved with a device of the type mentioned at the outset, comprising a) a first grinding device for transverse grinding of the weld transverse to its longitudinal direction and a second grinding device for subsequent longitudinal grinding of the weld in its longitudinal direction or b) a single grinding device for transverse grinding the weld transverse to the longitudinal direction and then longitudinally grinding the weld in its longitudinal direction, the single grinding device being rotatably mounted about an axis transverse to the weld.
    The proposed measures a particularly flat and high-quality surface of the metal strip is achieved. In doing so, one makes use of the circumstance that, during transverse grinding, the weld seam can be very selectively and almost selectively removed at relatively low grinding pressure, whereas the longitudinal grinding can be used very well for equalization or homogenization of the strip surface. Overall, the combination of the two methods makes it possible to achieve qualitatively very high quality tape surfaces.
    Welding as such may be part of the manufacturing process. There then results a method for the production of a metal strip comprising the
    steps
    Welding at least two parts to a metal strip,
    Transverse grinding of the weld transverse to its longitudinal direction and subsequent longitudinal grinding of the weld in its longitudinal direction.
    Further advantageous embodiments and modifications of the invention will become apparent from the subclaims and from the description in Zusammenschaumit the figures. It is advantageous if the weld runs in the longitudinal extent of the metal strip. This makes it possible to produce comparatively wide metal bands. It is also advantageous if the transverse grinding and / or longitudinal grinding of the weld seam is carried out with a grinding wheel or grinding roller and / or a grinding belt. The abovementioned grinding media are particularly suitable for the stated purpose, because they have a long service life and thus enable efficient and dimensionally stable grinding, since a change of the abrasive medium during the processing of the sometimes a few hundred meters long welding seam can omit a change of the grinding medium. Said movement would both increase the processing time and degrade the Maßhaltig¬, since steps in the strip surface after a change of the abrasive medium can not be prevented or only with great effort.
    It is advantageous if the contact between the metal strip and a grinding medium during transverse grinding takes place along a line. As a result, the weld seam can be removed in a particularly targeted manner during transverse grinding with relatively low grinding pressure. Particularly suitable for this purpose are (sometimes narrow) grinding wheels, grinding rollers, but also Schleifbän¬ which touch the belt surface along a line.
    It is also advantageous if the contact between the metal strip and the grinding medium during longitudinal grinding takes place on a surface. As a result, the belt surface can be homogenized or leveled out particularly well. In particular, sanding belts that lie flat on the metal belt are suitable for this purpose.
    However, it is also advantageous if the contact between the metal strip and the abrasive medium during longitudinal grinding takes place on a line. As a result, homogenization / leveling of the strip surface can take place at relatively low grinding pressure. In particular, for this purpose grinding discs / grinding rollers or abrasive belts can be used, which touch the belt surface along a line. It is also favorable if the feed during transverse grinding and longitudinal grinding takes place in the longitudinal direction of the weld seam. In this way comparatively long belts can be processed with relatively small grinding devices.
    In addition, it is favorable if the feed during transverse grinding also takes place transversely to the longitudinal direction of the weld seam. In this way, the welding area can be ground, in particular when using a grinding wheel or grinding wheel plane. In this case, the feed in the longitudinal direction beispiels¬weise an oscillating movement is superimposed in the transverse direction, or the movement takes place stepwise, that is, a feed in the longitudinal direction only beifertig carried out movement in the transverse direction. Of course, this variant is of course not limited to the use of grinding wheels / grinding rollers, but of course can also be used in abrasive belts, in particular when their contact with the metal strip is on a line.
    In a further advantageous variant of the production method, longitudinal grinding takes place over the entire bandwidth. As a result, a particularly smooth surface of the metal strip can be produced.
    It is also advantageous if the transverse grinding takes place in a reduced area compared to the entire bandwidth. This allows the grinding area to be concentrated on the weld seam, leaving areas of transverse grinding further away from the weld unimpaired.
    It is also advantageous if a wider Schleifmedi¬um is used for the longitudinal grinding than for the transverse grinding. As a result, during transverse grinding, a relatively high removal rate can be achieved with a comparatively low grinding pressure, whereas the surface of the metal strip is well leveled during longitudinal grinding by the wide abrasive medium.
    In an advantageous variant of the production method, the transverse grinding and longitudinal grinding takes place at positions offset in the longitudinal direction of the weld seam at the same time. In this case, a longitudinal grinding device is arranged in the feed direction behind a transverse grinding device. By doing so, the metal tape can be made particularly fast.
    In another advantageous variant of the production method, the transverse grinding and longitudinal grinding takes place in succession. In this variant, the transverse grinding and the longitudinal grinding are decoupled from one another, as a result of which very specific influence on the grinding result can be taken. In addition, there is also the basic possibility to use only a single grinding device for transverse grinding and longitudinal grinding, which is rotated in each case by 90 °.
    It is also advantageous if the grinding process takes place on the endless, closed belt. In this way, the grinding operations can be performed well in several passes. For example, the transverse grinding can be carried out in several passes and also the subsequent longitudinal grinding.
    Finally, it is also advantageous if the grinding operation takes place on the open belt. In this way, the grinding process can take place even in the case of long belts in a narrow space, for example in which the strip to be ground is unwound from a reel and the ground belt is reeled onto another reel. In principle, however, the abrasive belt can be laid even without the use of reels.
    It should be noted at this point that the variants disclosed for the production process and the resulting advantages relate equally to the disclosed device and vice versa.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description apply mutatis mutandis to the same parts with the same reference numerals. same component names can be transferred. Also, the location information chosen in the description, such as up, down, laterally, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis in a position change. Furthermore, individual features or combinations of features from the illustrated and described different exemplary embodiments may also represent separate, inventive or inventive solutions.
    Fig. 1 shows an exemplary and purely schematically illustrated plant for Ferti¬gung a metal strip in side view, Fig. 2 in plan view. Concretely, Figures 1 and 2 show a metal band 1 welded together along the weld 2 of two parts. The metal strip 1 is designed as an endless belt and guided around two rollers 3 and 4, of which at least one is driven. Furthermore, FIG. 1 shows a sanding roller 5, as well as a belt sanding device which comprises three deflection rollers 6, 7 and 8 as well as a sanding belt 9. Finally, in Fig. 1, a counter-plate 10 for Abstüt¬zung of the metal strip 1 is shown.
    The function of the arrangement shown in Figures 1 and 2 is now as follows:
    In a first step, the metal strip 1 is provided. In a further step, the weld 2 / the metal strip 1 is ground transversely to the longitudinal extent of the weld seam 2. In the concrete example, the grinding roller 5 is used for this purpose, whose grinding direction (not the feed direction) is set to " A " bezeichnetist. This movement is effected by rotation of the grinding roller 5 about a horizontal, along the weld 2 aligned axis. In a further step, the weld 2 / the metal strip 1 is ground in the longitudinal direction of the weld 2. In the concrete example, the belt grinder 7.9 is used for this purpose, whose grinding direction (not the feed direction) is set to " B " bezeichnetist. The metal strip 1 is rotated by means of the rollers 3 and 4 in the direction " C " moves and thus causes a longitudinal feed during transverse grinding and longitudinal grinding.
    In addition to the longitudinal feed in direction C, during transverse grinding, advancement also takes place in the direction D transverse to the longitudinal direction of the weld seam 2. In this way, the feed area in the longitudinal direction C can be superimposed with an oscillating movement in the transverse direction D, for example with a triangular, sawtooth or sinusoidal profile. The movement in the direction D can also take place in stages. In this case, feeding in the longitudinal direction C is performed only when the movement is completed in the transverse direction D. During the movement in the direction D, the metal strip 1 is thus stopped.
    In the present method, the grinding roller 5 is used for the transverse grinding of the weld seam 2, while the grinding belt 9 is used for the longitudinal grinding. Although the abovementioned grinding media are well suited for the stated purpose, because they have a long service life and thus enable efficient and dimensionally stable grinding, however This is not the only option. Of course, it is also conceivable that the transverse grinding and the longitudinal grinding with the grinding belt 9 takes place, or that the transverse grinding and the longitudinal grinding with the grinding roller 5 takes place, or that the transverse grinding takes place with the grinding belt 9 and the longitudinal grinding with the grinding roller 5. In particular, it is also generally conceivable to use, instead of the grinding roller 5, a grinding wheel whose essential difference from the grinding roller 5 is the larger diameter / width ratio. Lower contact surface reduces the grinding pressure, which promotes high removal rates.
    In general, it is advantageous if the contact between the metal strip 1 and the grinding medium 5 during transverse grinding takes place along a line, as shown in FIGS. 1 and 2. Instead of grinding wheels 5 or grinding wheels, abrasive belts can also be used for this, which contact the belt surface along a line (see also FIGS. 3 and 4). As a result of the line contact, the weld seam 2 during transverse grinding can be removed in a particularly targeted manner at a relatively low grinding pressure.
    It is furthermore advantageous if the contact between the metal strip 1 and the abrasive medium 9 takes place during longitudinal grinding on a surface, as shown in FIGS. 1 and 2. As a result, the strip surface can be homogenized or leveled particularly well.
    In principle, however, it is also possible for the contact between the metal strip 1 and the grinding medium 9 to take place on a line during longitudinal grinding. As a result, homogenization / leveling of the strip surface can take place at relatively low grinding pressure. In particular, sanding discs 5 or sanding belts 9 which contact the belt surface along a line can be used for this purpose (see also FIGS. 3 to 6).
    A further feature of the method illustrated with the aid of FIGS. 1 and 2 is that the longitudinal grinding takes place over the entire bandwidth. As a result, a particularly level surface can be produced on the metal strip 1. Furthermore, the transverse grinding in FIGS. 1 and 2 takes place in a region reduced in size over the entire bandwidth, which is denoted by Έ " bezeichnetist. Thereby, the grinding area can be concentrated on the weld seam 2, whereby regions of the transverse grinding which are further away from the weld 2 remain unaffected. In principle, however, it is also conceivable that the longitudinal grinding does not take place over the entire bandwidth and / or the transverse grinding over the entire bandwidth (see also FIGS. 3 and 4).
    A further feature of the method illustrated with the aid of FIGS. 1 and 2 is that a wider abrasive medium 9 is used for longitudinal grinding than for transverse grinding. As a result, a relatively high removal rate can be achieved with comparatively low grinding pressure during transverse grinding, whereas the surface of the metal strip 1 during longitudinal grinding is well leveled by the wide abrasive belt 9 (see also FIGS. 3 and 4).
    In principle, the transverse grinding and longitudinal grinding can take place at positions offset in the longitudinal direction of the weld 2 at the same time. In FIGS. 1 and 2, the sanding roller 5 and the sanding belt 9 are activated simultaneously. By means of this procedure, the metal strip 1 can be produced particularly quickly.
    However, it is also conceivable that the transverse grinding and longitudinal grinding takes place behind one another in terms of time, that is to say that the grinding roller 5 and the grinding belt 9 are not active simultaneously. The decoupling of transverse loops and Längsschlei¬fen can be selectively influenced on the grinding result. In addition, there is also the possibility in principle of using only a single grinding device for the transverse grinding and the longitudinal grinding, which is rotated by 90 ° in each case (see also FIGS. 3 and 4). This is favored by the fact that the
    Grinding process in Figures 1 and 2 at the endless, closed band 1 er¬folgen.
    FIGS. 3 and 4 now show a further embodiment, which is basically very similar to the variant shown in FIGS. 1 and 2. By contrast, a single belt grinding device 6.9 is now used for longitudinal grinding and transverse grinding. FIGS. 3 and 4 show the device in the position for longitudinal grinding. However, in this embodiment, the belt grinding device 6..9 can be rotated by 90 ° around its vertical axis (see the double arrow in FIG. 4), whereby only a single grinding device 6.9 is required for transverse grinding and longitudinal grinding. Of course, instead of a single belt grinder 6.9 but also two separate belt grinder 6..9 can be provided, which are rotated by 90 ° gegenei¬nander.
    With regard to the cross feed in the direction D, the statement corresponding to FIGS. 1 and 2 applies mutatis mutandis. That is to say, the transverse feed can take place in an oscillating manner (for example triangular, sawtooth or sinusoidal) simultaneously with the longitudinal feed in direction C, or in temporal succession.
    In Figs. 3 and 4, the abrasive belt 9 contacts the metal belt 1 both in cross grinding and in longitudinal grinding along a line. It is also conceivable, however, that for the longitudinal grinding a contact between the grinding belt 9 and metal belt 1 is provided on a surface, as already shown in FIGS. 1 and 2. This can be accomplished by the two-part belt grinder 6..9 are provided, which are rotated by 90 ° about their Hoch¬ axis against each other, with the provided for the transverse grinding Bandschleifeinrichtung 6..9 only with the roller 6 rests (line contact) and the the longitudinal grinding provided belt grinder 6..9 as inFig. 1 and 2 is arranged (surface contact). Alternatively, it is also imaginable that a single belt grinding 6.9 can be rotated not only by 90 ° about the Hoch¬achse, but also about the axis of the roller 6 (60 ° here), so switched between line contact and surface contact
    Miorrlon can be used for the purpose of longitudinally grinding and transverse grinding of differently wide abrasive belts 9. In principle, it is furthermore conceivable to provide surface contact between the grinding belt 9 and the metal belt 1 even during cross grinding.
    Another feature of the method illustrated with the aid of Figures 3 and 4 is that the longitudinal grinding does not occur over the entire bandwidth, but the transverse grinding over the entire bandwidth (see also the area E) C also during longitudinal grinding an oscillating movement in the direction D can be superimposed, or they can also be carried out one behind the other.
    Figures 5 and 6 show a further variant, which is similar to the variants shown so far. In contrast, however, a grinding wheel 11 is used for the transverse grinding and a grinding roller 5 for the longitudinal grinding. In this context, it is also noted that the transverse grinding and longitudinal grinding is also conceivable with a single grinding roller 5 which can be rotated 90 ° about its vertical axis (compare FIGS. 3 and 4).
    Finally, FIGS. 7 and 8 show a variant embodiment in which the grinding operation takes place on the open band 1. Concretely, the tape 1 to be ground is unwound from a reel 12 and the ground tape 1 is reeled onto another reel 13. In this way, the grinding process can take place even in long bands 1 in a narrow space. Of course, all of the previously mentioned embodiments can also be applied to the grinding of open tape 1. Of course, even a newly laid (and not reeled) metal strip 1 can be ground in the specified manner.
    It is also noted at this point that the individual grinding operations can generally be carried out in several passes. For example, the transverse grinding can be carried out in several passes and also the subsequent longitudinal grinding.
    It is also conceivable that the longitudinal feed in the direction C is not effected by a movement of the metal strip 1, but by a movement of the Schleifeinrich¬ tions 5..9. A combination of both variants is possible.
    It should also be noted that, although the manufacturing process has been explained with reference to a metal strip 1 whose weld 2 is oriented longitudinally, it is of course equally applicable to transverse welds.
    Finally, a method results for the production of a metal strip 1, um¬fassend the steps
    Providing a metal strip 1 which comprises at least two parts welded together at a weld seam 2,
    Transversely grinding the weld 2 transverse to its longitudinal direction and then longitudinally grinding the weld 2 in the longitudinal direction thereof. The welding of the at least two parts to a metal strip 1 may of course be part of the manufacturing process.
    The proposed measures a particularly flat and high-quality surface of the metal strip 1 is achieved. In this case, one makes use of the fact that the weld 2 can be very selectively and almost selectively removed during transverse grinding at a relatively low grinding pressure, whereas the longitudinal grinding can be used very well for the leveling or homogenization of the strip surface. Overall, the combination of the two methods makes it possible to achieve qualitatively very high quality belt surfaces.
    The exemplary embodiments show possible embodiments of a production method for a metal strip 1, wherein it should be noted at this point that the invention is not restricted to the specifically illustrated embodiments thereof, but rather various combinations of the individual embodiments are possible among each other and this Variati Because of the doctrine of technical action by means of independent invention, it is possible for the skilled person skilled in the art to obtain this option. So there are all conceivable variants, by
    Combinations of individual details of the illustrated and described Ausfüh¬rungsvariante are possible, including the scope of protection.
    In particular, it is also noted that the illustrated devices may in reality also comprise more or fewer components than shown and are sometimes shown in greatly simplified form in the figures.
    Finally, for the sake of convenience, it should be noted that the illustrated devices as well as their components have also been shown partly out of scale and / or enlarged and / or reduced in size for a better understanding of their construction.
    The problem underlying the independent inventive solutions can be taken from the description.
