A device for forming a fabric edge with two doup ends and one stationary thread in which there are thread guides for the doup ends and the stationary thread, the doup ends can be twisted together after every second weft insertion with the crossing of the stationary thread, the thread guides for the doup ends and the thread guides for the stationary thread are fitted to pivot towards each other to form a shed between the doup ends on the one hand and the stationary thread on the other, whereby the thread guides (3a, 3b or 2) take the form of needles to guide the doup ends (7a, 7b) or the stationary thread (8). The two needles (3a, 3b) for the doup ends are parallel and spaced apart through a rotary support (4) in such a way that the needles (2) for the stationary thread (8) can penetrate between the needles for the doup ends (3a, 3b).
