    • A triple-thread stitch is intended for sewing webs of netting over their edges, wherein one thread (2) forms straight loops (3) and two other threads (4 and 6) form turned loops (5 and 7). In the method of producing this triple-thread stitch, performed in a machine wherein the loop-forming members are the sewing needle (8), looper needle (9) and looper hook (10), the thread (6) of the looper hook (10) is formed into a turned loop (7) which is moved about the needle (8) until the latter's thread (4) forms a turned loop (5), and driven through the straight loop (3) of the thread (2) of the looper needle (9). In the machine for sewing netting webs over their edges with a triple-thread chain stitch, the looper hook (10) is mounted for moving about the needle (8) at the side of the device (17) for advancing the webs, which provides for forming from the thread ( 4) of the needle (8) a turned loop (5) when the looper hook (10) moves the turned loop (7) intermediate the needle (8) and its thread (4).
