Abstract:
1. A dryer fabric, which has a bottom surface and a surface facing a paper web to be dried and which is woven of a plurality of machine direction longitudinal yarns and a plurality of cross machine direction transverse yarns, and in which dryer fabric there are at least two superposed machine direction yarn systems, namely, the paper side machine direction yarns and the backside machine direction yarns, and in which dryer fabric there is at least one first cross machine direction connecting end and at least one second cross machine direction connecting end, each of the connecting ends comprising a seam area and on the outermost edge of the connecting end a plurality of seam loops for interconnecting the connecting ends of the dryer fabric and for providing a dryer fabric in the form of a closed loop, and which seam area has a predetermined length in machine direction extending from the seam loops to a cross machine direction line where the basic structure of the dryer fabric begins, and in which a plurality of paper side first machine direction yarns are arranged to form said seam loops and in which a plurality of paper side second machine direction yarns are arranged to form the outermost edge of the seam area, and in which the paper side machine direction yarns are cut and fastened off by weaving in the seam area on the backside of the dryer fabric such that in the seam area there is at least one cross machine direction fasten-off row, and further, in which the machine direction yarns of the backside extend to said fasten-off row, and wherein the seam area comprises at least two cross machine direction fasten-off rows at a machine direction distance from one another, machine direction yarns that form seam loops have been fastened off in a first fasten-off row and machine direction yarns that form an edge of the seam area have been fastened off in at least one second fasten-off row, and one fasten-off row is substantially at the beginning line of the seam area.
