    Background of the invention The invention relates to a dryer fabric, which has a bottom surface and a surface facing a web of paper to be dried and which is woven with a plurality of longitudinal machine direction yarns and a plurality of cross-machine direction yarns; and wherein in the dryer fabric there are at least two superposed machine direction yarn systems, namely the machine direction yarns on the paper side and the machine side yarns on the back side; and in which dryer fabric there is at least a first cross-connect end and at least one second cross-connect end, each of the connection ends comprising a seam area and at the outermost edge outside of the connection end, a plurality of seam loops for interconnecting the connection ends of the dryer fabric and for providing a dryer fabric in the form of a closed loop; and which sewing zone has a predetermined length in the machine direction extending from the sewing loops to a cross-machine line where the basic structure of the dryer fabric begins; and wherein a plurality of first paper-side machine direction yarns are arranged to form said seam loops and wherein a plurality of second paper-side machine direction yarns are arranged to form the outermost edge of the sewing area; and wherein the paper-side machine direction yarns are cut and stitched in the seam area on the back side of the dryer fabric so that in the sewing area there is at least one row of stitches in the cross direction; and further wherein the machine direction yarns on the rear side extend to said stopping row.
    The invention also relates to a dryer fabric stitch zone at a dryer fabric connection end comprising: a bottom surface and a surface facing a web of paper to be dried; a plurality of cross-machine direction yarns and a plurality of machine direction longitudinal yarns arranged to form at least two superposed machine direction yarn systems, namely a paper-side machine direction yarn system and a yarn-in-sense system machine on the back side; the first outermost edge of the seam area comprising, a plurality of seam loops; the seam area having a predetermined length in the machine direction extending from the first edge to the second edge on the side of the base structure of the dryer fabric; in which sewing area, a plurality of first paper-side machine direction yarns are arranged to form said sewing loops and in which a plurality of second paper-side machine direction yarns are arranged to form the outermost edge; outside the sewing area; and wherein the paper-side machine direction yarns are cut and stitched in the stitching zone on the back side of the dryer fabric so that there is at least one crosswise stopping row in the seam area and, in addition, in which the machine direction yarns on the rear side extend to the stopping row.
    The drying section of a paper machine employs dryer cloths by which the paper web to be dried is applied through the drying section. The dryer fabric is made of yarns resistant to high temperatures and humidity using appropriate weaves for the dryer fabric to have a given permeability. The dryer cloth is run over the paper machine like an endless loop. The dryer fabric can be made endless or it can be provided with a seam. For stitching, there may be provided at both ends of the dryer fabric, seaming loops which may be intertwined during assembly to form a seam loop passage in which a sewing thread or a corresponding member may be arranged to Interconnect the ends of the fabric. A problem with conventional dryer fabrics is that the sewing areas to be made at the ends of the dryer fabric on the seam machine are cumbersome and time consuming.
    brief description
    The object of the invention is to provide a new improved dryer fabric with stitching, and a seam area of the dryer fabric.
    The dryer fabric of the invention is characterized in that the seam area comprises at least two cross-machine stopping rows at a machine direction distance from each other; in that the machine direction yarns which form seam loops have been stopped in a first stopping row and the machine direction yarns which form an edge of the seam area have been stopped in at least a second row of stitches. stop; and in that a stopping row is substantially at the start line of the stitch area.
    The seam area of the dryer fabric according to the invention is characterized in that the seam area comprises at least two lines stopped in cross direction at a machine direction distance from each other; in that the machine direction yarns which form seam loops have been stopped in a first stopping row and the machine direction yarns which form an edge of the seam area have been stopped in at least a second row of stitches. stop; and in that a stop row is substantially at the second edge of the seam area.
    The basic idea of the invention is that the basic structure of the dryer fabric comprises at least two superimposed machine direction yarn systems, namely a paper-side machine direction yarn system and a yarn-in-sense system. machine on the back side. Some of the paper side machine direction yarns form seam loops at the dryer fabric connection ends and some of the paper side machine direction yarns form an edge of the seam area at the connecting end. All of the paper-side machine direction yarns therefore turn back at the connecting end and are stopped on the back side of the fabric on a separate seam machine. The paper-side machine direction yarns are woven using appropriate weave on the sewing area and are cut. At the cutoff point, there is provided a stopping point and a plurality of aligned stopping points form a crosswise stopping row. There are at least two stopping rows, because the threads forming stitching loops are stopped in the first stopping row. The threads forming the edge of the seam area are stopped in one or more second stopping rows at a distance from the first stopping row. The stopping rows are therefore located at different points seen in the machine direction. In addition, one of said stopping rows is placed substantially on the demarcation line between the stitch area and the base fabric. The machine direction threads of the back side system are woven to the stopping rows.
    The invention has the advantage that stop rows should not be separately reinforced by means of silicone or the like, because the stitching row of the threads forming seam loops is at a different location than the row of stitches. stopping the threads forming the edge of the sewing area. In addition, when a stopping row is provided on the demarcation line between the stitch area and the base fabric, the advantage is obtained that the stitch area is rapidly woven on the sewing machine. In fact, at the level of the machine direction yarn stopped on the demarcation line of the base fabric, it is not necessary to weave a machine-less thread from the back side to the sewing machine in the sewing area and, therefore, the number of work cycles on the seam machine is lower and therefore, the work can be done more quickly.
    The basic idea of one embodiment is that the first stopping row is substantially on the line of demarcation of the stitch area and the base fabric. Thus, at the threads forming the edges of the seam area, the back side machine direction yarns are woven on the sewing machine on the seam area to the second stitching row.
    The basic idea of one embodiment is that the dryer fabric comprises at least two superposed layers of fabric, namely a topsheet and a backdrop. The top canvas is on the paper side and the backdrop is on the back side. Between the canvas and the backdrop, there may be one or more intermediate canvases. Each fabric layer may be an independent fabric layer that includes specific longitudinal yarns and specific transverse yarns. The fabric layers can be woven simultaneously on the weaving machine and interconnected by a plurality of threads.
    The basic idea of one embodiment is that the longitudinal threads of the topsheet are stopped with substantially the same weave pattern as the longitudinal threads of the backdrop in the base structure of the dryer fabric.
    The basic idea of one embodiment is that the longitudinal threads of the topsheet are stopped with a different weave pattern than the longitudinal threads of the backdrop in the base structure of the dryer fabric.
    The basic idea of one embodiment is that, seen in the cross direction, every second machine direction yarn of the topsheet is arranged to form the sewing loops mentioned above and each other yarn in the sense The machine's top cloth is arranged to form the outermost edge of the seam area.
    The basic idea of one embodiment is that the dryer fabric comprises cross-threaded bottom wires, i.e., bottom frames, at least in the base structure of the dryer fabric. The dryer fabric may also include bottom fields in the seam area.
    The basic idea of one embodiment is that the seam area has a monolayer structure.
    The basic idea of one embodiment is that between the topsheet and the backdrop there is a plurality of cross-way fillers and the fillers are arranged in the dryer fabric without crisscross with the threads of the canvas and the backdrop. The fillers can provide increased tension to the structure of the dryer fabric. In addition, the filling threads can add rigidity in cross-machine direction of the dryer fabric and can therefore make the fabric more stable.
    The basic idea of one embodiment is that the topsheet and the backdrop include a 4-ply weave.
    The basic idea of one embodiment is that the machine direction yarns of the topsheet and the backdrop are of flat section, for example oval or rectangular yarns. As is known, the flat wires are rigid in one direction and very flexible in another direction. As a result, the flat wire woven fabric layer is very sturdy in the plane of the fabric. The flat wires support the structure of the fabric in the surface direction thereof. In addition, when flat wires are used, the bottom surface may be smoother than in the case of round wires, and therefore the fabric carries less air. So the canvas has good aerodynamic properties and good behavior on the paper machine. In addition, the surface facing the web to be dried may be smoother when using flat yarns rather than using round yarns.
    The basic idea of one embodiment is that the dryer fabric has a monolayer base structure in which there are at least two superposed layers of machine direction yarns and a crosswise yarn layer.

    DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS OF THE INVENTION FIG. 1 shows a greatly simplified view of a dryer fabric 1 which can run in the machine direction MD and which has a width in the cross direction CDM. The dryer fabric 1 may comprise one or more seams 2 separately woven on the seam machine, whereby the fabric may be connected to a closed loop in the drying section of a paper machine. The seam makes the assembly of dryer fabric 1 easier and faster.
    Figure 2 shows a dryer fabric 1 of the invention CMD cross-sectional view. Dryer fabric 1 has a paper-side surface P, against which the paper web to be dried can be arranged in the drying section. In addition, on the opposite side of the dryer fabric, there is a bottom surface T which can be supported against the rolls of the paper machine. The dryer fabric 1 may comprise at least two superposed canvases, namely a top fabric 3 on the paper side and a backdrop 4 on the back T. The top fabric 3 and the backdrop 4 are formed on the weaving machine and they may each comprise specific yarn systems, i.e. MD machine direction yarns 5, 6 and CMD 7, 8 cross-machine direction yarns. bottom 4 can be woven on the same weaving machine at the same time. The topsheet 3 and the backdrop 4 may be interconnected such that a plurality of machine direction threads 5 of the topsheet 3 run through the cross-machine direction yarns 8 of the backdrop 4 and correspondingly, the machine direction yarns 6 of the backdrop 4 run through the cross-machine direction yarns 7 of the topsheet 3. All of the machine direction yarns, or just a few, may participate in the binding. The dryer fabric 1 can be woven in such a way that the machine-direction running threads 5, 6 MD are warp threads and the CMD-running threads 7, 8 are weft threads. Between the fabric layers 3, 4, there may be a plurality of cross-directional filling threads 9 which render the structure of the dryer fabric 1 more dense. The filling threads 9 can be arranged during the weaving in such a way that they do not intersect at all with the threads in the topsheet 3 and the backdrop 4. In addition, the backdrop 4 can comprise cross-machine grounding yarns 10 which bond with the machine-direction yarns 6 of the backdrop 4. The topsheet 3 and the backdrop 4 may have a 4-ply weave structure.
    FIG. 2 also shows, in addition to the base structure 11 of the fabric, a connection end 12 of the fabric, which comprises seam loops 13 and a seam zone S. The demarcation line between the basic structure 11 and the sewing zone S is indicated by a line in the cross direction L. The sewing zone S must have a given length in the machine direction MD so that the sewing loops 13 have sufficient strength and the threads 5 to be stopped are firmly connected to the seam area S. Thus, the threads in the sewing area S must be treated after the actual weave of the fabric on a seam machine but the seam machine does not cause a change in the structure of the seam base fabric 11. Figure 2 further shows, in phantom, a second connection end 14 of the fabric which also includes sewing loops. The seam loops 13 at the connecting ends 12, 14 can be arranged to interlock on the paper machine and a sewing thread 15 or the like, interconnecting the connection ends, can be arranged in the sewing loop passage obtained. . As can be seen from the figure, the seam area S may have a different structure than the base structure 11 of the fabric. Outside the seam area S there is a skewed wire 16 through which some of the machine direction yarns 5b of the topsheet 3 are arranged to run, whereby an edge 17 is produced. in the outermost part of the seam area S.
    Figure 3 and parts a through d of the figure illustrate how a connection end 12 of the dryer fabric is formed on the seam machine. The lower two parts a and b of the figure show a machine direction yarn weaving pattern 5a forming seam loops 13 and the two highest c and d parts of the figure show a weave pattern of 5b forming the edge 17 of the seam area S. To easily understand, a dashed line 18 on parts a and b of the figure indicate how the wire 5a of the topsheet rotates around a auxiliary thread 19 when the seam is woven and returns forming a seam loop 13. In addition, a dashed line 20 on parts c and d of the figure indicates how the yarn 5b of the topsheet 3 rotates around the seam. outermost yarn, i.e., edge yarn 16 of the sewing area S when the seam is woven and returns thereby forming the edge 17 of the seam area S. The yarns 5a, 5b are stopped so that they are woven on the side of the back of the a sewing zone S and are then cut at the breakpoints K1 and K2. Viewed in the cross-machine direction of the fabric, the fabric can be woven in such a way that every second yarn in the machine direction forms sewing loops 13 and that each other yarn can participate in forming the edge 17. Of course, other weave structures may also be used, for example, such that two adjacent yarns form seam loops and two adjacent yarns participate in forming the edge.
    In the cross-machine direction CMD, a plurality of aligned stopping points K1 and correspondingly K2 respectively form in the fabric a first stopping row R1 and a second stopping row R2. The threads 5a forming seam loops are stopped at the line L where the first row of stops R1 is formed. In this case, the machine direction yarn 6 of the backdrop 4 at the yarn 5a must not be processed on the seam machine. The wires 5b forming the edge 17 are stopped at a distance M in the machine direction MD of the first row of stop R1, whereby a second row of stops R2 is formed at this point. At the yarn 5b forming the edge 17, the machine direction yarn 6 of the backdrop 4 is woven to the second row of stops R2 for a distance M. The weave patterns of the yarn 6 in the part M can be the same as in the base part 11 of the canvas. In addition, the weave patterns of the yarn 5a returning around the auxiliary yarn 19 and the yarn 5b returning around the edge yarn 16 may correspond to the weave pattern of the machine direction yarn 6 of the backdrop 4. D ' on the other hand, in some cases, their weave patterns may differ from the weave pattern of the yarn 6, and the weave patterns of the yarns 5a, 5b need not always be the same.
    Figures 4 and 5 show an alternative dryer fabric 1 and a connecting end 12 thereof. The fabric differs from the solution shown in Figs. 2 and 3 in that the seam area S does not include cross-machine direction threads 10. The seam area S has a monolayer structure. The line L is clearly distinct from the structure as a point from which no bottom thread 10 will appear in the direction of the seam area S. Another difference with respect to the solution shown in the preceding figures 2 and 3 is in that the threads 5a and 5b are stopped in the seam area S using a weave pattern which is different from that of the machine direction thread 6 of the backdrop 4. For the rest, the details shown on the Previous figures also apply to the dryer fabric of Figures 4 and 5.
    If desired, instead of a single second row of stops R2 shown in FIGS. 2 to 5, wires 5b forming edge 17 may also be stopped in a plurality of stopping rows, for example two, three or four rows of stopping. However, the threads 5a forming seam loops 13 are always stopped near the line L so that the number of sewing work cycles can be reduced.
    In another alternative embodiment, the seam forming threads 5a are stopped in the second row of stops R2 and the threads 5b forming the edge 17 are stopped in the first row of stops R1. In this case, the machine direction yarn 6 of the backdrop 4 located at the yarn 5 does not need to be treated on the seam machine.
    The sewing zone S of the invention may also be applied to a dryer fabric having a monolayer structure.
    The dryer fabric allows the application of various polymeric wire materials, structures and wire sections. The machine direction yarns of the dryer fabric may be of flat section, for example, oval or rectangular yarns. The topsheet and the backdrop may have a monolayer structure that includes crosswise yarns in a layer, or in some cases may have a bilayer structure. The weave of the cloth may be a four-blade structure, but may also have another structure, for example a six or eight-blade structure. In addition, it is possible that the fabric does not include any cross-threaded bottom wire 10 shown in the figures. In addition, the dryer fabric does not necessarily include cross-fill son 9, but the stability and tension of the fabric can be obtained by other means.
    In some cases, features disclosed in the present application may be used as such, regardless of other characteristics. On the other hand, features disclosed in this application may be combined, if desired, to provide various combinations.
    The drawings and the description thereof are intended solely to illustrate the inventive idea. The details of the invention may vary within the scope of the claims.
