    The invention relates to an endless belt with a metal band body.
    In the production of laminated corrugated board devices with endless belts of the type mentioned are used. Due to the process, the conventional devices for producing corrugated cardboard are structurally limited in their length available for production. However, this represents a significant limitation in terms of increasing the productivity of existing equipment.
    It is therefore an object of the invention to provide the ability to increase the productivity of existing equipment for the production of laminated paperboard without increasing their length in the material flow direction.
    This object is achieved with an endless belt of the aforementioned type according to the invention that the ratio of a circumferential length of the endless belt to a width extending transversely to the circumferential length of the endless belt is less than or equal to 1.5.
    The solution according to the invention provides endless belts whose width is very high in relation to their circumferential length. In this way, the surface area of the endless belts available for the production of laminated paperboard is substantially increased without increasing the process length of the devices. This makes it possible to produce significantly more corrugated board in the same production time.
    According to a variant of the invention, which is characterized by a simple manufacturability, it can be provided that end edges of the band body are welded together so that the band body forms a closed ring bil det, the endless belt in a connecting region of the end edges of the band body at least one Has weld.
    An advantageous embodiment provides that the at least one weld of the endless belt has an average roughness depth which is a maximum of 8.0 pm.
    In order to ensure a uniform heat transfer over the entire endless belt, the at least one weld of the endless belt can have a flatness deviation of less than or equal to 0.3 mm.
    According to an advantageous development of the invention, the weld has a seam width of less than or equal to 4 mm. According to a variant of the invention, the at least one weld can advantageously have a straightness deviation between 0 and 15 mm over its entire seam length.
    Depending on the shape of the available starting material to achieve the dimensions according to the invention, the band body may be formed from a single part or from at least two parts which are welded together at facing longitudinal edges and / or at mutually facing end edges, all Welding seams of the endless belt according to one of claims 2 to 5 are formed, wherein a difference in thickness between each weld and immediately adjacent areas of the endless belt is less than or equal to 0.1 mm or 0 - 20% of an average thickness of the endless belt.
    According to an advantageous development, it can be provided that, viewed over its entire circumferential length, the endless belt has a deviation of the width between 0 and 5 mm.
    Furthermore, it can be provided that a difference in length between a first circumferentially extending side edge of the endless belt and a second extending in the circumferential direction of the endless belt side edge of the endless belt between 0 and 5 mm, wherein the distance between the two side edges of the width of the endless belt corresponds. Conveniently, the tape body has an average thickness between 0.2 and 2 mm, in particular between 0, 5 and 1 mm, wherein the average thickness varies over the entire circumferential length of the endless belt by less than 20%.
    According to one embodiment of the invention, the endless belt may have a flatness index that is less than or equal to 8.
    According to a variant of the invention, the endless belt can have a circumferential length between 0.2 m and 10 m, in particular between 1 m and 4 m, a thickness between 0.1 mm and 1 mm, in particular between 0.2 mm and 0.8 mm and have a width between 0.2 m and 10 m, in particular between 2 m and 4 m.
    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.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    In each case, in a highly simplified, schematic representation:
    Fig. 1 is a perspective view of an endless belt according to the invention and
    Fig. 2 is a diagram showing a ripple of the endless belt.
    By way of introduction, it should be noted that in the embodiments described differently, identical parts have the same reference numerals or the same component designation.
    Drawings are provided, wherein the disclosures contained in the entire description can be transferred mutatis mutandis to the same parts with the same reference numerals or identical 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 these position information in a change in position mutatis mutandis to transfer to the new location. All statements of value ranges in the present description should be understood to include any and all sub-ranges thereof, e.g. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all sub-areas 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 has a metal belt body 2. The band body 2 forms a closed ring and, according to one embodiment, can be formed integrally and continuously without a weld.
    As an alternative to a design without a weld, however, end edges 3, 4 of the band body 2 can also be welded together. In a connecting region of the end edges 3 and 4, the endless belt 1 then has a weld seam 5. The weld 5 can in this case transversely (90 °) or obliquely at any angle, for example 45 °, 80 °, etc., to a band longitudinal direction. The ratio of a circumferential length l of the endless belt 1 to a width b of the endless belt 1 running transversely to the circumferential length l is less than or equal to 1.5.
    The circumferential length I can be between 0.2 m and 10 m, in particular between 1 m and 3 m. Furthermore, the endless belt 1 may have a thickness between 0.1 mm and 1 mm, in particular between 0.2 mm and 0.8 mm and a width (b) between 0.2 m and 10 m, in particular between 2 m and 4 m , Thus, in one embodiment, the endless belt 1 according to the invention may for example have a length l of about 2900 mm and a width b of about 2800 mm.
    The surface of the endless belt 1 may be treated or untreated. Thus, the surface may be polished, ground, painted, etched, structured or smooth, kiss-gel and / or sandblasted and / or coated, for example with a chrome coating or a protective and / or non-stick coating.
    The weld 5 of the endless belt 1, for example, have an average roughness Rz, which is a maximum of 8.0 pm. Furthermore, the weld 5 may have a flatness deviation of less than or equal to 0.3 mm. The flatness deviation can be determined by means of a hair ruler in a known per se. Here, the hair ruler with a measuring edge, for example, transversely to the longitudinal extent of the weld to be tested 5 are placed. In the backlighting, the deviation of the weld seam from a straight surface, referred to as "flatness deviation", can be determined on the basis of the size of a light gap lying between the measuring edge of the hair ruler and the surface of the weld 5. A quantitative measurement of the gap can be made by means of a feeler gauge. The determination of the flatness deviation of the weld seam 5 is preferably carried out at a belt tension of the endless belt 1 of 30 N / mm 2.
    In addition, the weld 5 may have a seam width of less than or equal to 4 mm. Also, the weld 5 over its entire seam length may have a straightness deviation between 0 and 15 mm. To determine the straightness deviation of the weld seam 5, a straight line can be laid through a start and an end point of the weld seam 5, a normal distance of points of the weld seam 5 lying next to this straight line being used as a measure of the straightness deviation of the weld seam 5.
    The band body 2 may also consist of two or more parts 6, 7, 8, which are welded together at mutually facing longitudinal edges and / or at mutually facing end edges. Thus, the endless belt 1 can be made of three or more interconnected metal sheets, which can be arranged in the tape longitudinal direction one behind the other. Two immediately adjacent plates can each be welded to each other at adjacent edges miteinan of. The welds between the sheets can here transverse or oblique to the tape longitudinal direction.
    Alternatively or in addition to the embodiment mentioned in the last paragraph, the endless belt 1 can also consist of two or more adjacent parts 6, 7, 8, which are welded together at side edges in the belt longitudinal direction, as shown for example in Fig. 1. In Fig. 1, the longitudinal welds, over which the parts 6, 7 and 8 are connected, indicated by the reference numerals 9 and 10. Preferably, the welds 9, 10 of the endless belt 1 are similar to the weld 5, wherein a difference in thickness between each weld 5, 9, 10 and immediately adjacent areas of the endless belt 1 is less than or equal to 0.1 mm or 0 - 20% average thickness of the endless belt is 1.
    As an alternative to a multi-part embodiment and to a non-welded embodiment, the band body 2 may be formed by a helically wound metal sheet which is held together by a helical weld. In this case, the weld also preferably has all the above-described properties of the weld 5, with the exception of the specifications for the straightness deviation.
    The endless belt 1, viewed over its entire circumferential length, has a deviation of the width b between 0 and 5 mm, wherein a difference in length between a side edge 11 of the endless belt 19 running in the first circumferential direction and a second side edge 12 of the endless belt 1 extending in the circumferential direction of the endless belt 1 between 0 and 5 mm, wherein the distance between the two side edges 11,12 corresponds to the width b of the endless belt 1.
    Furthermore, the band body 2 may have an average thickness between 0.2 and 2 mm, in particular between 0, 5 and 1 mm, wherein the average thickness over the entire circumferential length I of the endless belt 1 considered by less than 20%, in particular by less than 15% or less than 10%, varies.
    Moreover, the endless belt 1 according to a preferred embodiment of the invention may be made of a steel having 0.09% C, 15.0% Cr, 7.0% 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.
    Preferably, the endless belt according to the invention has a flatness index I which is less than or equal to 8, in particular less than or equal to 6 or less than or equal to 4. The flatness index is determined as shown in FIG. 2 as the ratio between the difference in the length of the wavelength L * and the wavelength L to the wavelength L, and becomes larger
    This results in simplified:
    With L * = length of the wavy line, L = wavelength and h = wave height (double amplitude).
    For the sake of order, it should finally be pointed out that in order to better understand the construction of the endless belt according to the invention, this or its components have been shown partially unevenly and / or enlarged and / or reduced in size.
