    In an overedge stitch type consisting of two needle threads, one looper thread and a workpiece carrying these threads, loops of the needle threads are arranged at different spacings parallel to the edge of the workpiece within the latter. In addition, these loops of the needle threads may also exhibit different spacing from the workpiece edge.

    The invention relates to sewing manufacture, namely to the type of stitch through the edge and the method of its production,
    The purpose of the invention is to improve the quality of the connecting seam by obtaining a reliable non-deforming resilient and elastic connecting shaft.
    FIG. 1 shows the type of stitch across the hem; in fig. 2 is a schematic image of one side of the workpiece with needle penetration points; in fig. 3 - modified stitch; in fig. 4 is a schematic of one side of a workpiece for a modified stitch.
    To form the one shown in FIG. 1 stitch through the edge, the needles 1, 2 must pass the threads 3, 4 respectively through the workpiece 5. The threads 3, 4 form on the exit side of the needles 1, 2 on the workpiece 5 loops 6 and 7 respectively, through which the looper tip 8 is directed together with its clamping thread 9, leaving the position above or below the edge 10 of the workpiece, Loop 8 transfers the thread 9 as a loop 11 through loops 6, 8 of the needle threads 3, 4 and around the edge of the workpiece to another part of the workpiece, and the tip of the looper can be Either above or below the edge 10 of the workpiece.
    Simultaneously or shortly after the described operation, the needles 1.2 are pulled back until they again leave their points of penetration (T, B, C, Fig. 2). When moving forward again, the needles 1, 2 pass through loops 11 of an anchoring thread 9, which at this moment is on the input or entry side of the needle of the workpiece 5. After the needles 1, 2 enter these loops 11, the looper 8 returns to its initial position on the opposite side of the workpiece, thanks

    the gift of which the initially formed loops of needle-like threads 6, 7 dissolve. Due to the corresponding tension of the threads, they again stretch opposite the workpiece 5 so that the mutual formation of a loop (loop formation) falls on the exit point of the loop 7 of the needle thread 4. Loop of the thread 3, which is guided by needle 2, is pulled away from its point of entry towards the point of entry of thread 4, the movement of which is directed by needle 1.
    After the looper 8 returns from its back position, the operation is repeated. After pulling out the needles 1, 2 from the workpiece 5 and from the loop 11 of the anchoring thread 9, the mutual loops of the feed loops on the needle entrance side of the workpiece 5 are also retracted towards the insertion point of the thread loop 4.
    Shown in FIG. 3 and 4, a modified embodiment of the invention, and more specifically the shown modified stitch over the edge, differs from that shown in FIG. 1 and 2 stitches in the sense that the entry points Ba, Ca (CJH 4) and, respectively, two needles 1a, 2a (fig, 3) are spaced relative to each other only in one direction, namely in the direction perpendicular to the direction of sewing A or relative to the edge 10 of the workpiece, but not in the direction perpendicular to this edge, as shown in FIG. 1, 2. Compared with the known technical solutions, this modified version of the location of the vanishing points and exit points by a single step in the direction of crosslinking also has its advantages.
     In other modified embodiments of the invention, it is possible, by changing the adjustment of the needle thread, i.e., for example, by changing the tension of the thread, to move the looping of the threads 3, Over, 4, 43, 9 towards other points of the workpiece. , and best also towards the edge of the workpiece. In this latter case, if parts of the workpiece are already stitched together, an exceptionally flat seam is obtained.
    In addition, by rotating the feed direction A by 180 °, it will be possible to obtain a modified version of the invention with respect to the mutual positions of the mutual looping of the thread without any significant change in the type of stitch itself.
    FIG. 1 clearly shows that the needles 1,2, which form the points of penetration B and C, respectively, due to their specific location on the tile of the needle bed also
    steps are arranged in relation to each other and in parallel with respect to the edge 10 of the workpiece at a distance less than one stitch length, and specifically at a distance of half the stitch length. In another embodiment of the invention, the needles 1, 2 may be located on the needle bar so that they will form a mutually stepwise position parallel to the edge 10 of the workpiece over a distance of more than one stitch length.
    In the latter cases it is necessary to ensure that in the seam formed with
    In 5 stitches through the edge, all points of penetration B were located in ledges and parallel to the edge of the workpiece in relation to all points of penetration C, since only in this case can
    0 will realize all the advantages of the invention, for example, achieve higher crosslinking rates.
