The present invention relates to a method for automatic initiation of working position of a crossed coil manufactured by a textile machine after coiling interruption, particularly after portion change. The textile machine is provided with a tongs bobbin used to pick up yarns from a feeding pipe and convey to a pivoting area of the suction nozzle, the suction nozzle transfers the yarns to a working area of a yarns transfer device of a crossed coil exchanger. The yarns transfer device collects and cuts off the yarns and fixes the yarns on a crossed coil inside a working position pipe frame. After the tongs bobbin collects the yarns and conveys the yarns to the pivoting area of the suction nozzle, the suction nozzle is pivoted to a yarns transfer position after passing through a yarn segment extending between the tongs bobbin and the feeding pipe and is formed into a yarns loop, herein the thrum of the tongs bobbin side is still fixed on the tongs bobbin. A yarn part connected with the yarn segment and the feedi
