PROBLEM TO BE SOLVED: To provide a ring twister in which tension of a metal fiber is arranged to be appropriate in a twisted yarn obtained by twisting the metal fiber, a chemical fiber and the like.SOLUTION: A ring twister is arranged such that a twisted yarn obtained by twisting a metal fiber M fed from at least one bobbin Mb for the metal fiber with a chemical fiber and/or a natural fiber C fed from at least one bobbin Cb for a raw yarn fiber is wound around a winding bobbin 31 rotating at a predetermined speed. The ring twister comprises a bobbin rotating mechanism 11 for rotating the bobbin for the metal fiber in the fed direction for the metal fiber. The ring twister is arranged such that the tension of the metal fiber is set at a predetermined value or range by rotating the bobbin for the metal fiber. |
