A helical cord that forms an elliptical shape will be manufactured so that the length-to-width ratio or the dimensions of the shaped form of the cord that is shaped in the length direction can be changed. A cord (C) is passed successively to through-holes (21H, 22H) in a stationary and a movable shaping body (21, 22) opposite each other in a shaping device (20). At this time, the movable shaping body (22) is moved along the stationary shaping body (21) by a moving apparatus, the reciprocal through-holes (21H, 22H) are brought off-center, and the cord (C) passing between the off-centered through-holes (21H, 22H) is shaped by being bent and deformed. The moving apparatus is also provided with first and second displacement mechanisms that displace the movable shaping body (22) in the X and Y directions. The movable shaping body (22) is thus displaced back and forth by amounts of displacement individually set synchronized to the two directions, the movable shaping body (22) is moved continuously interlocked to the displacement in the two directions, and the cord (C) that is passed through is shaped. |
