Device for forming a doup fabric edge

Device for forming a fabric edge with two doup ends (7a, 7b) and one stationary thread (8) in which there are thread guides (3a, 3b or 2,) for the doup ends (7a, 7b) and the stationary thread (8), the doup ends (7a, 7b) can be twisted together after every second weft insertion with the crossing of the stationary thread (8), the thread guides (3a, 3b or 2,) for the doup ends (7a, 7b) and the thread guides (3a, 3b or 2,) for the stationary thread (8) are arranged to pivot towards each other to form a shed between the doup ends (7a, 7b) on the one hand and the stationary thread (8) on the other,

• characterized in that the thread guides (3a, 3b or 2) take the form of two needles (3a, 3b) to guide the doup ends (7a, 7b) and a needle (2) for the stationary thread (8), wherein 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 needle (2) for the stationary thread (8) can penetrate between the two needles (3a, 3b) for the doup ends (7a, 7b).
