The invention concerns a stitched seam for high-tensile woven fabric strips, in particular for dryer screen fabric for paper machine clothing, wherein the warp thread loops (4, 4') of the two fabric sections (1, 2) to be interconnected are connected at the location of the common seam by means of a closure wire (7). At least one of the two outer regions of the two fabric strip sections to be interconnected comprises a worked-in helix (5, 5', 6, 6') at the location of the seam. Each of the helices embraces at least one weft thread (10) and the closure thread (7). The other region of the stitched seam of the ends of the two fabric strip sections consists of the loops (4, 4') formed by the warp threads of the fabric.
