Abstract

PROBLEM TO BE SOLVED: To prevent the mutual interference of taper wires when the taper wire is taken up, by comprising a spool feeding means for feeding a taper wire take-up spool in an axial direction at the pitch same as a spiral groove. SOLUTION: When a clamper 21 is closed, a taper wire is clamped. When a motor is rotated in this condition, the torque is successively transmitted to a pulley 38 and a sleeve 33, so that a spool shaft 31 is rotated, and is moved in an axial direction at the pitch same as a groove of a spool body 11, while keeping the screw motion of the spool shaft 31 with a nut 35. Whereby a taper wire take-up spool 100 is rotated, and is fed in the axial direction at the pitch same as the groove of the spool body 11, and the taper wire is spirally taken up in the groove of the spool body 11.
