    The invention relates to a method for producing an endless belt from at least two plate-shaped metal sheets.
    Furthermore, the invention relates to an endless belt.
    Moreover, the invention relates to a device which has at least two rollers between which an endless belt rotates.
    As small bands trained as endless belts, such as Radantriebsbänder, as used in vehicle test stands, or small bands as they can be used in devices for the production of laminated corrugated cardboard, are usually produced by bending and welding of metal sheets. This results in the problem that the raw material is often in the form of metal panels with a size dictated by the manufacturer of the metal panels, so that it is often necessary to weld metal panels together to achieve a desired strip length. So far, however, there is still no solution that allows a largely automated bending and welding of the metal sheets to an endless belt, so that a large number of manufacturing steps still have to be carried out manually.
    For the production of pipes from a metal sheet or a metal sheet, it is known from EP0701878 B1 to bend the metal sheet in a holding device by means of tension straps to a pipe or ring and weld the abutting free end edges together. The method known from EP0701878 B1 allows the fully automatic production of pipes from metal sheets. 2/21 N2012 / 30400 2
    However, until now it has not been possible to produce an endless belt consisting of two or more metal sheets with the known solution, since the known method is only suitable for processing a single metal sheet. It is therefore an object of the invention to find a way to overcome the above-mentioned disadvantage of the prior art.
    This object is achieved with a method of the type mentioned in the present invention, that the at least two metal sheets are inserted with one edge in advance in one of two opposing receptacles at least one removable connecting element and form a plate composite, whereupon free end edges of the plate assembly, the the edges arranged in the at least one connecting element of the metal sheets are opposite to each other, bent and welded together, whereupon the at least one connecting element removed and previously bent by the at least one connecting element interconnected edges of the metal sheets to each other and welded together.
    The solution according to the invention makes it possible, by using a connecting element, to connect two metal sheets to form a sheet composite, which can then be processed automatically like a single metal sheet. It is thus a merit of the invention to easily enable the automated production of an endless belt of a plurality of metal sheets.
    According to an advantageous embodiment of the invention, it may be provided that the metal sheets connected to one another are brought into a holding device by means of tension straps in an annular shape, wherein the free end edges of the plate assembly are clamped in a clamping device and moved towards each other until a gap between the free end edges is closed, whereupon the free end edges are welded together by means of a welding device. Here, the metal sheets are advantageously connected to each other before insertion into the holding device by means of at least one connecting element. 3/21 N2012 / 30400 3
    Particularly well, the invention is suitable for the production of a three-piece endless belt. According to a corresponding variant of the invention, it is provided that three metal sheets are used for the production of the strip, wherein in each case two adjacent metal sheets are connected to each other at least one connecting element to form a plate composite of the three metal sheets, the frontal, free end edges thereof bent to each other and welded together, whereupon at least a first disposed between a middle metal sheet and a first outer metal sheet connecting element is removed and the previously interconnected via the at least one first connecting element edges of the middle metal sheet and the first outer metal sheet are bent and welded together whereupon at least a second connecting element arranged between the middle metal sheet and a second outer metal sheet is removed and previously surrounded by the at least one second connecting element bent in mutually connected edges of the middle and the second outer metal sheet to each other and welded together.
    It is particularly advantageous for typical small-belt applications if the endless belt produced has three interconnected sections made of metal sheets and arranged one behind the other in the strip longitudinal direction, with two immediately adjacent sections being welded to each other at adjoining edges of the sections. Due to the special design of the endless belt according to the invention can be realized in a simple way from commercially prefabricated metal plates small bands for different applications.
    An embodiment of the invention which, for example, is particularly suitable for use as a wheel drive belt or for use in a device for producing laminated corrugated cardboard, provides that the endless belt has a circumferential length between 0.2 m and 10 m, in particular between 1 m and 3 m, a thickness between 0.1 mm and 1 mm, in particular between 0.2 mm and 0.8 mm and a width between 0.2 m and 4 m, in particular between 2 m and 3 m. 4/21 N2012 / 30400 4
    Particularly good wear and durability characteristics can be achieved by making the endless belt of a steel containing 0.09% C, 15.0% Cr, 7.0% Ni, 0.7% Cu and 0.4% Ti. The remaining portions of the steel according to this variant of the invention are formed by Fe.
    It has proven particularly advantageous for many applications if the strip has a tensile strength of 1200 to 1600 N / mm 2.
    According to a preferred embodiment, the band may have a modulus of elasticity of 190000 to 210000 N / mm 2.
    The endless belt according to the invention is particularly well suited for use in a device which has at least two rollers between which the endless belt revolves. Such a device can be, for example, a device for producing corrugated cardboard laminated on at least one side or else a test stand for automobiles.
    The invention together with further advantages will be explained with reference to some non-limiting embodiments, which are illustrated in the drawings. These show in a schematically simplified representation:

    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 names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions. All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. the indication 1 to 10 should be understood to include all sub-ranges, starting from the lower limit 1 and the upper limit 10, i. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.
    According to FIG. 1, an endless belt 1 according to the invention can be manufactured from three interconnected metal sheets 2, 3, 4. In the strip longitudinal direction are formed by the metal sheets 2, 3, 4 successively arranged sections I, II, III. Two immediately adjacent sections I, II, III are welded together at mutually adjacent edges of sections I, II, III. The weld may in this case extend transversely or obliquely to the tape longitudinal direction. Preferably, the endless belt 1 is a so-called small band. Thus, the endless belt 1 has a circumferential length between 0.2 m and 10 m, in particular between 1 m and 3 m, a thickness between 0.1 mm and 1 mm, in particular between 0.2 mm and 0.8 mm and a width between 0.2 m and 4m, in particular between 2 m and 3 m.
    Moreover, the endless belt 1 according to a preferred embodiment of the invention may be made of a steel which is 0.09% C, 15.0% Cr, 7.0% 6/21 N2012 / 30400 6
    Ni, 0.7% Cu and 0.4% Ti, wherein the remaining portions of the steel are preferably formed by Fe. Further, the endless belt 1 may have a tensile strength of 1200 to 1600 N / mm 2 and a modulus of elasticity of 190000 to 210000 N / mm 2.
    For the production of the endless belt 1 shown in FIG. 1, as shown in FIG. 2, in a first step, two adjacent metal sheets 2, 3, 4 each having a connecting element 5, 5 a connected to each other, to a plate assembly 6 of the three Metal sheets 2, 3, 4 to form.
    For this purpose, according to FIG. 3, two metal sheets 2, 3, 4, each with an edge 9, 10, 11, 12, can be inserted into one of two mutually opposite receptacles of the respective connecting element 5, 5a. The connecting elements 5, 5a can, as shown by way of example in FIG. 3, have an H-shaped cross-section. Alternatively, it would also be possible that the connecting elements 5, 5a are designed as end regions of the metal sheets 2, 3, 4 cross-sleeves without inner, the edges 9, 10, 11, 12 separating partition. Also, the connecting elements 5, 5a need not extend over the entire width of the metal plates as shown. Thus, e would also be possible that the length of the connecting elements 5, 5a are shorter than the length of the edges 9, 10, 11, 12. If the latter is the case, instead of a connecting element 5, 5a between two metal plates 2, 3, 4, a plurality of connecting elements 5, 5a arranged along the edges 9, 10, 11, 12 can also be arranged. Also, the connecting elements 5, 5a may be provided with fixing mechanisms, such as screws, or clamps to prevent slippage.
    After formation of the plate composite 6, free end edges 7, 8 of the plate composite 6, which are opposite to the arranged in the at least one connecting element 5, 5a edges 9, 10, 11, 12 of the metal sheets 2, 3, 4, bent and welded together. For welding, different welding methods can be used, for example laser welding, TIG welding, plasma welding, MIG-MAG welding etc. 7/21 N2012 / 30400 7
    The bending of the plate assembly 6 and the welding of the free end edges 7, 8 together preferably takes place with a device 13, as shown in FIGS. 4 and 5. The device 13 may, according to a variant of the invention, as described in EP 0 701 878 A1 mentioned above, be formed and have a holding device 14 with tension straps 15. The tension straps 15 are arranged one behind the other in the viewing direction in FIGS. 4 and 5, so that only the first of the tension straps 15 can be seen in the illustration. The holding device 14 may have adjustable side cheeks 16 and 17, the distance between them can be changed. The side cheeks 16 and 17 serve as a holder for the tension straps 15. The tension straps 15 can be guided over arranged on the side cheeks 16 and 17 deflections 18, 19. The free ends of the tension straps 15 can be wound on reels 20, 21, which can be connected to controlled drives for adjusting the length and the lateral positioning of the tension straps 15. The holding device 14, which can be arranged on a tool carriage which can be moved out of the device 13, can be located outside the device 13 for equipping with the plate assembly 6. For equipping the holding device 13 of the plate assembly 6 is placed on the tension straps 5, wherein the side cheeks 16 and 17 are moved apart. The tension straps 15 can be tensioned to a fixed position for the respective band diameter. By moving the side cheeks 16 and 17 of the plate assembly 6 is brought into a ringfömige form, wherein the free ends of the plate assembly 6 can be clamped in a clamping device 22. The clamping device 22 may have a support 23, for example in the form of a rod or tube, and two separately operable jaws 24, 25. Once the plate assembly 6 is brought into an annular shape and the end edges 7, 8 are clamped in the tensioning device 22, a gap between the free end edges 7, 8 can be closed by unilaterally increasing the tensile force on the tension straps 15. After pushing together the end edges 7, 8, the clamping force of the clamping device 22 can be increased and the position of the end edges 7, 8 are fixed, so that no displacement of the end edges 7, 8 longer possible. Hereupon, the plate composite 6 in the device 8/21 N2012 / 30400 8 13 can be welded by means of a welding device 26 along the mutually bent end edges 7, 8.
    After welding the end edges 7, 8, the holding device 14 can be moved out of the device 13 and the now annular plate assembly 6 are removed. Then the connecting element 5 is removed and the plate assembly 6 is again placed in the holding device 14 and the previously interconnected via the connecting element 5 edges 9, 10 are bent in the manner described above as before the end edges 7, 8 to each other and welded together. After welding the edges 9, 10, the entire process of removal and placement of the holding device 14 can repeat, in which case the connecting element 5a is removed and finally the previously interconnected via the second connecting element 5a edges 11, 12 to each other in the manner described above bent and welded together to form the endless belt 1.
    At this point it should also be mentioned that the production of the endless belt 1 from the plate assembly 6 by means of the device 13 before further processing steps, such as straightening, editing the edges of the metal sheets 2, 3, 4, loops can precede or follow.
    FIG. 6 shows by way of example a device 27 for laminating corrugated cardboard. The device 27 comprises an endless belt 1, as shown in Fig. 1, on. The endless belt 1 passes over two rollers or drums 28, 29. One of the rollers 28, 29 may be provided, for example, as a tension roller and the other as a deflection roller. Furthermore, the device 27 may include an upper corrugating roller 30 and a lower corrugating roller 31 which mesh with each other. A glue application can take place on a first paper web 32 by means of a glue application roller 33, wherein a second paper web 34 is pressed onto the applied adhesive layer by the endless belt 1, which is used here as a pressure belt.
    The endless belt 1 can also be used in devices not shown here, such as in drive devices for automotive test benches use. 9/21 N2012 / 30400 9
