In such a device, a ring part 8 serving as a nearly circular ballooning guide means for guiding the weft Y reeled from the yarn feeding body 1 to form ballooning is provided between the yarn feeding body 1 and the weft guide 14, and the weft Y is pulled out onto the upper weft guide 14 side while being guided by the inner edge of the ring part 8. The ring member 8 has a clearance part 8a formed to lead the weft Y outward from the inner edge side and to lead the weft Y again into the inner edge side by the change of a yarn path at the time of changeover from the yarn feeding body 1 to the reserve yarn feeding body 2 through the pick-tail weft P.
