DETAILED DESCRIPTION
[0039] Referring to FIG. 1, a first strip 100 composed of a first metal and a second strip 101 composed of a second metal are welded to one another in their longitudinal direction to form a first composite strip. In this case, the longitudinal direction is the direction in which the strips 100 and 101 have the greatest extent. Subsequently, in the embodiment in FIG. 2, the strips are cladded onto the third strip 102 composed of a third metal. It is also possible for the third strip 102 to be composed of the first or the second metal. Since the width of the third strip 102 corresponds to the sum total of the widths of the first strip 100 and of the second strip 101, the cladding operation can take place in a conventional cladding apparatus. No, or hardly any, specific features have to be observed. In particular, the first strip 100 and the second strip 101 cannot be displaced relative to one another during the cladding operation. It is also ensured that there is no gap between the first strip 100 and the second strip 101 after the cladding operation.
[0040] FIG. 3 illustrates that the third strip 102 has been cladded onto the first composite strip. In principle, this can be effected in the same way as in the case of the embodiment from FIG. 2. Similar or identical advantages are likewise produced.
[0041] FIG. 4 illustrates the use of a second composite strip and of a fourth strip 400. The fourth strip 400 may be composed for example of the same material as the first strip 100. However, it is also possible for the fourth strip 400 to be composed of another metal or an alloy. In contrast to FIGS. 2 and 3, the first composite strip also comprises the fourth strip 400 in addition to the first strip 100 and the second strip 101. The fourth strip 400 is arranged next to the second strip 101 and is welded to the second strip 101. The second strip 101 is thus arranged between the first strip 100 and the fourth strip 400 and is welded to these two strips.
[0042] The second composite strip is formed in the same way as the first composite strip. The third strip 102 in the embodiment from FIG. 4 is wider than the third strip 102 in the embodiments from FIGS. 2 and 3, since its width corresponds to the sum total of the widths of the first and second composite strips.
[0043] The third strip 102 is arranged between the first composite strip and the second composite strip. The connections between the third strip 102 and the two composite strips are achieved by way of a cladding operation.
[0044] In the embodiment as per FIG. 4, there is also the advantage that, owing to the welds within the composite strips, there are no gaps and a displacement of the strips relative to one another during the cladding operation is impossible or at least made considerably more difficult.
[0045] FIG. 5 illustrates a fifth strip 500 which may be composed of the same material as the third strip 102. However, it is also possible for the fifth strip 500 to be composed of another metal or an alloy. In the embodiment as per FIG. 5, the first composite strip is arranged between the third strip 102 and the fifth strip 500. The connections of the first composite strip to the third strip 102 and to the fifth strip 500 are achieved by way of a cladding operation.
[0046] In the embodiment as per FIG. 5, there is also the advantage that, owing to the welds within the composite strip, there are no gaps and a displacement of the strips relative to one another during the cladding operation is impossible or at least made considerably more difficult.
[0047] In the embodiment as per FIG. 6, a relatively wide third strip 102 and a relatively wide fifth strip 500 are used. This is associated with the fact that the first composite strip is also very wide, since said first composite strip comprises two first strips 100, three second strips 101 and two fourth strips 400, which are welded to one another. In this case, the fourth strips 400 are twice as wide as the first strips 100.
[0048] Also illustrated in FIG. 6 are two dashed lines which serve merely to illustrate lines along which the third strip 102, the fifth strip 500 and the first composite strip are severed in order to produce a plurality of composite materials, as illustrated in FIG. 5. A prerequisite for this is that the fourth strips 400 are twice as wide as the first strips 100 and are composed of the same material as the first strips 100.
[0049] With the embodiment from FIG. 6, it is possible to produce a comparatively large number of composite materials with relatively little effort. It is possible to first produce a coil with the embodiment from FIG. 6. The severing operation can subsequently be carried out, such that the number of composite materials is multiplied.
[0050] FIG. 7 likewise illustrates an embodiment which can be severed along the lines depicted in dashed fashion, in order to produce a relatively large number of composite materials with relatively little effort. In this case, the procedure is analogous to the procedure described in relation to FIG. 6. The advantages are also similar or identical. From the embodiment as per FIG. 7, it is thus possible to produce a relatively large amount of composite material, as illustrated in FIG. 4, with relatively little effort.
[0051] FIG. 8 illustrates a composite material comprising three layers of strips. A third strip 102 is arranged between a first composite strip and a second composite strip. The first composite strip and the second composite strip each comprise a first strip 100 and a strip 101 which is welded to the first strip 100. The embodiment as per FIG. 8 differs from the embodiment from FIG. 4 mainly in that the first and the second composite strip do not comprise a fourth strip.
[0052] FIG. 9 illustrates a composite material comprising three layers of strips. A first composite strip comprises a first strip 100 and a strip 101 which is welded to the first strip 100. The first composite strip is arranged between a third strip 102 and a fifth strip 500. The embodiment as per FIG. 9 differs from the embodiment from FIG. 5 mainly in that the first composite strip does not comprise a fourth strip.
[0053] The embodiment illustrated in FIG. 10 is similar to the embodiment illustrated in FIG. 6. The first composite strip is composed of first strips 100, second strips 101 and a fourth strip. Here, the fourth strip 400 is twice as wide as the first strips 100 and is composed of the same material as the first strips 100. The dashed lines in FIG. 10 illustrate severing lines along which the third strip, the fifth strip and the first composite strip are severed in order to produce a plurality of composite materials, as illustrated in FIG. 9. It is thus possible to produce a relatively large number of composite materials with relatively little effort.
[0054] The embodiment illustrated in FIG. 11 is similar to the embodiment illustrated in FIG. 7. The first and the second composite strip are composed of first strips 100, second strips 101 and a fourth strip 400. Here, the fourth strips 400 are twice as wide as the first strips 100 and are composed of the same material as the first strips 100. The dashed lines in FIG. 11 illustrate severing lines along which the first composite strip, the second composite strip and the third strip 102 are severed in order to produce a plurality of composite materials, as illustrated in FIG. 8. It is thus possible to produce a relatively large number of composite materials with relatively little effort.
[0055] An alternative to the above-mentioned welded connections is illustrated in FIG. 12. It concerns a first composite strip which comprises a first strip 1200 and a second strip 1201. The first strip 1200 is connected to the second strip in a form-fitting manner. The form-fitting connection is achieved by way of an interlocking of the two strips 1200 and 1201 with one another. In principle, this type of connection can be employed wherever two or more strips are connected to one another in a materially bonded manner by for example being welded to one another.
