    WOVEN SIEVE WITH FLAT CHAINS
    The invention relates to a woven wire, in particular forming fabric, for use in a machine producing and / or processing a fibrous web, in particular paper, board or tissue machine, according to the preamble of patent claim 1.
    At Formiers for use in paper, board or tissue machines a variety of often conflicting requirements are made. Thus, for the production of paper or cardboard of high quality, they must provide as smooth a web contact side as possible which can be brought into contact with the fibrous web and also have a dewatering behavior that is as uniform as possible over the web contact side. In order to ensure effective and rapid Entwäs¬serung especially in high-speed machines, such Siebeferner must have the lowest possible internal volume in order to keep the so-called "water hauling" as low as possible. On the other hand, however, drainage should not be too abrupt, as otherwise insufficient retention of fibers and fillers will be provided. In times of rising energy and raw material costs, such screens must not have a high load absorption on drive energy, for example because of low dimensional stability and / or due to slippage of the screens on the drive elements. The low dimensional stability can be caused, for example, by stretching of the wires in the machine direction (MD direction) and / or insufficient rigidity of such screens in the cross machine direction (CD direction) which can lead to "fluttering" of these screens. Furthermore, such screens must have a long service life in operation, which, among other things, requires a high wear volume on the machine contact side of such screens.
    In order to meet at least some of the above requirements, so-called SSB screens have been proposed in the past, which are constructed of two mutually independent layers of fabric, which in turn are connected by binding threads.
    A further development of such SSB sieves is given, for example, in US Pat. No. 6,179,013, in which, in order to reduce the internal volume of such sieves, it is advisable to use machine transverse direction yarns (CD yarns) with a flattened cross-section in the lower fabric layer providing the machine contact side , A disadvantage of the screening proposed in this document is its too low rigidity in the cross-machine direction, provided by the flattened machine transverse direction threads (CD threads), which provide a lower bending stiffness than CD threads with a circular cross-sectional area. Incidentally, it has been found that sieves with CD threads having a cross-sectional area with a flattened shape are difficult to produce, since the CD threads, which are usually weft threads, can often twist during weft insertion, resulting in a non-reproducible weave structure can lead.
    Also known from GB2157328 is a so-called two-ply wire having two superimposed layers of CD yarns interwoven with MD yarns of flattened cross-sectional shape by interweaving the MD yarns alternately with CD yarns of the two plies. Such screens known from GB'328 have the disadvantage that the MD-threads receiving the essential part of the drive power change between the two CD-thread layers and the MD threads therefore contract the CD-thread layers during tensile loading in the MD direction, which causes elongation Such screens in the MD direction result, whereby much drive power for the elongation is "destroyed". Furthermore, fabrics with flattened filaments at the web contact side exhibit unsatisfactory marking behavior due to increased hydraulic and topographical marks against screens with filaments of circular cross-sectional area at the web contact side.
    Based on the above-described disadvantages of known from the prior art sieves, it is the object of the present invention to provide sieves for use in Pa¬pier-, board or tissue machines, which with low tendency to mark a high dimensional stability associated with a low Provide internal volume, which, moreover, is easy and inexpensive to produce.
    The object is achieved by a woven wire according to the patent claim 1.
    Characterized in that the web contact side providing the first fabric layer is formed by threads with round cross-section, a first fabric layer is provided with low hydraulic and topographic marking.
    Characterized in that the second fabric layer includes MD threads with flattened cross-section, a screen is provided which provides a lower internal volume coupled with high dimensional stability. The substantial tensile load involved in operating a screen in a papermaking, paperboard or tissue machine is provided by the MD threads of the second, i.e. the fabric layer providing the machine contact side, since the MD yarns of the first, i.e., the web contact side, providing fabric layer must be very thin to avoid marks. In order to be able to ensure a given dimensional stability in the MD direction when the wire is operated in the machine, the MD threads of the second fabric layer must have a specific cross-sectional area. Since the MD yarns of the second fabric layer according to the invention have a flattened cross-sectional area, according to the invention, the dimensional stability can be maintained by reducing the height of the yarns while widening these yarns against fabrics with round MD yarns having the same cross-sectional area in the second fabric layer. As a result, the thickness of the second fabric layer and thus of the screen is reduced, whereby the so-called water drag can be effectively prevented. By extending the flattened filaments in the MD direction, the transverse stability of the screen, i. the CD-directional stability of the screen is not adversely affected, i. there is provided a second fabric layer, and thus a wire, which, in comparison to a screen with round MD yarns having the same cross-sectional area, has a reduced thickness with constant stability in the MD and CD directions.
    If the sieve according to the invention is a flat-woven sieve, ie a sieve in which the MD threads are warp threads and the CD threads are weft threads, the solution according to the invention further provides a sieve of small thickness which is simple and reproducible can be produced.
    For the purposes of the present invention, MD threads are understood to mean those threads which, when the sieve is used as intended in the fibrous web, extend in its MD direction. For the purposes of the present invention, the term "CD yarns" is to be understood as meaning yarns which, when the fabric is used as intended in the pulp web, extend in its CD direction.
    Advantageous embodiments and further developments of the invention are specified in the subclaims.
    It is conceivable, for example, that the shape of the cross-sectional area of the second MD threads is rectangular, square, bone-shaped or elliptical, wherein the shape of the cross-sectional area of the second MD threads in particular an aspect ratio of height (H) to width (W ) of less than one, in particular in the range of 1: 1.15 to 1: 1.75. It has been found that with the aspect ratio given above, an effective reduction in thickness of the inventive sieve can be achieved, coupled with a "twist-proof" handling of the MD threads during the production of the sieve.
    A rectangular or square shape of the cross-sectional area may also include that the edges of the rectangle or square are rounded, i. E. These forms can also include the two mutually parallel and opposite sides Rundun¬gen which connect the sides together.
    An aspect ratio of height (H) to width (W) less than one should be understood in particular to mean that the height (H) of the MD threads, i. the extent of which in the thickness direction of the sieve is less than its width (W), i. their extension in machine cross-section of the sieve.
    Preferably, the ratio of the number of first MD threads to second MD threads is greater than 1, wherein the number ratio is not an integer, in particular. In particular, ratios of the number of first MD threads to second MD threads of 3: 2, 4: 3 or 5: 3 are conceivable in this connection. By providing a screen with more MD strands in the first fabric layer than in the second fabric layer, a first fabric ply with high fiber support area is provided with a second open, i.e., second, ply fabric. provided on the machine contact side fabric. The first fabric layer can be made thereby maintaining a warp filling degree with thin MD yarns and CD yarns, whereby the thickness of the wire can be further reduced. By, the provision of second MD threads with abge¬flachter cross-sectional area in the second fabric layer, the openness of the second Geweb¬lage and thus the drainage behavior can be controlled within certain limits, beispiels¬weise by setting the above aspect ratio. This is very useful, especially in screens for use in "critical machines", as it is thus possible to provide individual problem solutions for the respective machine.
    In particular, it is provided that the ratio of the number of first CD threads to second CD threads is greater than 1, in particular is not an integer. For example, ratios of the number of first CD threads to second CD threads of 2: 1, 3: 2 or 5: 3 are conceivable. By means of this measure, in particular the above-mentioned measure for obtaining a web-like first fabric layer with high fiber support can be further developed with simultaneously open second fabric layer on the machine side, whereby such wire meshes are particularly suitable for use in high-speed machines, which are used to produce be used on printable paper or cardboard.
    Accordingly, in particular the ratio of the number of first MD threads to the second MD threads and the ratio of the number of first CD threads to second CD threads are each greater than 1. In particular, ratios such as 3: 2 (MD1 : MD2) combined with 3: 2 (CD1: CD2) or 3: 2 (MD1: MD2) combined with 2: 1 (CD1: CD2) or 3: 2 (MD1: MD2) combined with 5: 3 (CD1: CD2) (Bern: MD1 means first MD threads, MD2 means second MD threads, CD1 means first CD threads, CD2 means second CD threads).
    A further possible embodiment of the invention provides that the Maschinenkon¬taktseite is provided essentially by the second MD threads. In this case, therefore, the second CD threads run for the most part inside the screen according to the invention. In other words, in this embodiment, the second MD threads run along the largest part of their weaving path on the side of the second fabric layer facing the machine contact side a large part of the machine contact side of the second fabric layer, whereas the second CD yarns along the major part of their Wiebpfads on the side facing the web contact side of the second fabric layer, ie run inside the sieve. Accordingly, in this embodiment, the second MD yarns provide a majority of the wear volume of the screen. It is a so-called "warp runner". The fact that the cross-sectional area of the second MD yarns have a flattened shape can thereby provide a higher wear volume than round MD yarns.
    In this context, it is conceivable in particular that the second MD threads providing a large part of the machine contact side each form thread floats via at least four second CD threads adjacent to one another directly.
    In particular, according to an embodiment of the invention which is an alternative to the aforementioned embodiment, it is provided that the machine contact side is essentially provided by the second CD threads.
    In this case, therefore, the second MD threads extend for the most part of their web path inside the screen. In other words, in this embodiment, the second CD threads extend along most of their weaving path on the side of the second fabric layer facing the machine contact side, thereby providing a major portion of the machine contact side of the second fabric layer, whereas the second MD yarns run along most of its web path on the web contact side facing the second fabric layer, ie run inside the sieve. In this embodiment, accordingly, the second CD threads provide the wear volume of the screen. This is a so-called "shot-shooter". Because the cross-sectional area of the second MD yarns running inside the wire has a flattened shape, not only is the thickness of the second fabric layer per se reduced, but also because the flat MD yarns run inside the fabric, the distance between the two fabric layers is reduced whereby the relative mobility of the two fabric layers to each other and thus internal wear of the screen is effectively prevented.
    In order to further reduce the thickness of the screen, provision is made in particular for the second CD threads, which provide the majority of the machine contact side, to each form thread floatings via at least four directly adjacent second MD threads.
    It is also conceivable that the second CD threads ha¬ben a circular cross-sectional shape. As a result, a higher bending stiffness of the screen in the CD direction is achieved, in particular for a given cross-sectional area in comparison with screening with second CD threads which have been flattened.
    For screens which, for example, due to their weave structure already have sufficient bending stiffness in the CD direction, it may also be expedient to choose those with a flattened shape deviating from the circular shape instead of second CD threads having a circular cross-sectional area. This measure can in particular contribute to the further reduction in the thickness of the sieve.
    According to a further preferred embodiment of the invention it is provided that the ratio of the diameter (D) of the first MD threads to the height (H) of the second MD threads is in the range of 0.2 to 0.8, in particular 0.4 to 0.6. When sieving with the specified ratio, the inventive solution makes particularly positive, since the first or web contact side fabric layer is particularly fine compared to the second or machine contact side fabric layer and therefore the effect of thickness reduction paired with high dimensional stability especially in the MD direction and fine first fabric layer be¬sonders becomes apparent.
    Preferably, in this context, it is provided that the first CD threads and / or the binding threads have substantially the same diameter as the first MD threads. Essentially this is a deviation of not more than 20%, in particular a maximum of 10% to understand.
    If the sieve according to the invention is a so-called shot-type rotor, it is particularly useful if the ratio of the diameter (D) of the second CD threads to the height (H) of the second MD threads is greater than 1, in particular in the range of 1.5 to 3.0, preferably in the range of 1.6 to 2.5, since, without increasing the sieve thickness, the wear volume can be made large and the inner volume of the sieve can be kept small.
    If the sieve according to the invention is a so-called warp runner, it is particularly useful if the ratio of the diameter (D) of the second CD threads to the height (H) of the second MD threads is less than 1, in particular greater than 1 and is smaller than 1.5, since without increasing the sieve thickness, the wear volume can be made large and the inner volume of the sieve can be made small.
    Preferably, the binding yarns are arranged in pairs and are interwoven with yarns of the first and second fabric layers such that when a first binder yarn of the pair weaves with one or more yarns of the first fabric layer, the second binder yarn of the pair interweaves with one or more yarns of the second fabric layer, and vice versa In particular, by weaving the binding threads with the first MD threads and / or first CD threads, the weaving pattern formed by interweaving the first MD threads with the first CD threads is continued.
    Preferably, the binding threads extend in the CD thread direction. In this case, the weave pattern of the first fabric layer is formed by interweaving the binding yarns and the first CD yarns with the first MD yarns. Furthermore, it is preferably provided in this context that weaving patterns formed by interweaving the first MD threads with the first CD threads are continued by interweaving the binding threads with the first MD threads.
    Alternatively, it can be provided that extend the binding threads in MD Fadenrich-direction. In this case, the weave pattern of the first fabric layer is formed by weaving the first CD yarns with the first MD yarns and the binder yarns. Furthermore, it is preferably provided in this connection that the weaving pattern formed by interweaving the first MD threads with the first CD threads is continued by interweaving the binding threads with the first CD threads.
    In order to provide a first fabric layer with an extremely low marking web contact surface, a preferred embodiment of the invention provides that the weave pattern of the first fabric layer is a plain weave.
    To provide a good wear volume paired with low tendency Markmark¬ inclination, it proves to be advantageous if the weave pattern of the second fabric layer is an Atlas binding, such as a 5-händige, 6-schäftige or 7- schäftige Atlasbinding.
    According to a further embodiment of the invention, the sieve has a thickness, which is in particular in the range of 0.65 mm to 1.2 mm, more preferably in the range of 0.75 mm to 1.0 mm.
    In particular, the woven wire according to the invention has a permeability in the range of 310 cfm to 470 cfm, measured according to PCA: "Approved Standard Measuring Methods", Section E 4; Edition June 2002.
    Preferably, the first fabric layer provides in the range of at least 1600 support points to a maximum of 2200 support points per cm2.
    The invention will be further explained in a preferred embodiment with reference to FIGS. 1 shows a forming fabric according to the invention in the cutting direction along binding threads running in the CD direction, FIG. 2 shows the forming fabric according to the invention in the cutting direction along CD yarns, and FIG. 3 shows various possibilities of shapes of the cross-sectional surface. [0040] FIG the second MD threads.
    FIGS. 1 and 2 show a forming fabric 1 according to the invention which comprises a first fabric ply 2 providing a web contact side 2a and a second fabric ply 3 providing a machine contact fabric 3a, which are joined together by binding yarns 4, 5 extending in CD direction in pairs are.
    In the present case, the weave pattern of the first fabric layer 2 is a plain weave, which is formed by interweaving first MD threads 6 with the binding threads 4, 5 and by interweaving the first MD threads 6 with first CD threads 7.
    In this case, according to the invention, the first MD threads 6, the first CD threads 7 and the binding threads 4, 5 have a circular cross-sectional area of substantially equal size.
    The weave pattern of the second fabric layer 3 is a 5-strand satin weave which is formed by interweaving second MD yarns 8 with second CD yarns 9. Since the binding threads 4, 5 have a substantially smaller cross-sectional area than the second MD threads 8, and as the second CD threads 9, they do not contribute to the weave pattern of the second fabric layer 3.
    Here, the second MD yarns 8 have a cross-sectional area of a flattened shape, and the shape of the cross-sectional area of the second MD yarns 8 has an aspect ratio of height (H) to width (W) of 1: 1.65. Specifically, the shape of the cross-sectional area of the second MD yarns is rectangular in the present case, and the edges are rounded. Further, the second CD yarns 9 have a cross-sectional area in a circular shape.
    2, in this embodiment, the second CD threads 9 run along the major part of their weaving path on the side of the second fabric layer 3 facing the machine contact side 3a and in this case form a large part Machine contact side 3a of the second fabric layer 3 ready, whereas the second MD yarns 8 along the largest part of their Webpfads on the web contact side 2a facing side of the second fabric layer 3, ie run inside the sieve 1. As can be seen in FIG. 2, the second CD threads 9 provide, on the side of the second fabric layer 3 facing the machine contact side 3a, respective thread floats via at least four directly adjacent second MD threads 8.
    Accordingly, in this embodiment, the second CD threads 9 provide the wear volume of the screen. It is a so-called "shot runner".
    As can further be seen from the illustration of FIGS. 1 and 2, the ratio of the number of first MD threads 6 to second MD threads 8 in the present case is greater than 1 and not an entire number, namely 1.5. The present screen may further have a ratio of the number of first CD threads 7 to second CD threads 9 of 3: 2 or 2: 1.
    Further, the ratio of the diameter (D) of the first MD yarns 6 to the height (H) of the second MD yarns 8 is in the range of 0.45 to 0.5.
    FIG. 3 shows various possibilities of shapes of the cross-sectional area of the second MD threads 8.
    Here, the figure 3a shows a second MD yarn 8a whose cross-sectional area einerechteckige shape without rounded edges with an aspect ratio H to W of 1: 1.2.
    Furthermore, FIG. 3b shows a second MD yarn 8b whose cross-sectional area has a rectangular shape with rounded edges with an aspect ratio H to W of 1: 1.2.
    Further, Figure 3c shows a second MD thread 8c whose cross-sectional area is in the form of a dumbbell or bone, the aspect ratio H to W being 1: 1.7.
