PURPOSE:To shorten the length of a turning-lever engagement part in comparison with the interval between supporting members by arranging a turning lever so as to be rotatable and alternately engaged with the engaging member of a supporting member on the both side surfaces on the top edge side and the base edge side at the position where the width of a rail for transport varies. CONSTITUTION:A transport rail 1 has a wide width at the position corresponding to the machine base of a fly frame 2 and a narrow width at the part ranging from the intermediate part to a transport passage for a preparatory bobbin. A pair of rollers 5 are installed rotatably on the right and left sides of a bobbin transport body 4 which can travel on the rail 1, and a supporting member 7 suspending a bobbin hanger 6 is connected to the undersurface by a link 8. At the position where the width of the rail 1 varies, a turning lever 10 is rotatably supported onto a supporting shaft 11 installed in projection onto the under surface of the rail 1, and when the rail 1 is shifted to the wide part from the narrow width part, the engaging roller 9 of the supporting member 7 at the top edge is shifted to the guide rail 3a side by the guide by the guide part 12 of the lever 10, and the lever 10 is alternately turned in zigzag form. |
