PURPOSE:To improve the success ratio of ending operation remarkably by feeding the yarn end to the spinning part of the spinning rotor, thereby eliminating the ending miss caused by the excess and deficiency of the yarn length. CONSTITUTION:The yarn Y unwound from the package P is wound around the definite position (about the middle part) of the package P by rotating the package P forward while shifting the yarn Y by the yarn-shifting pin 41. The yarn path is extended to the part below the yarn cutting means 26, the yarn end is cut to make the unwound yarn length to the proper length, and the cut yarn end is positioned above the outlet of the delivery pipe 3 of the spinning unit 4. The package is rotated backward to feed a definite amount of the yarn to the spinning part of the spinning unit, and after ending, the package P is rotated forward to wind the ended yarn. |
