ABSTRACT:
The device for forming a fabric edge from two doup ends and one stationary thread comprises three guides for the doup ends and the stationary thread. The doup ends are twisted by the device after every second weft thread insertion. The thread guides for the doup ends and the thread guide for the stationary thread are arranged to pivot towards each other to form a shed between the doup ends on the one hand and the stationary thread on the other hand. The thread guides take the form of two needles to guide the doup ends and one needle for the stationary thread The two needles for the doup ends are parallel and spaced apart through a rotary support in such a way that the needle for the stationary thread can penetrate between the two needles for the doup ends.
