PROBLEM TO BE SOLVED: To provide a method for taking-up a double-pancake coil by which a double-pancake coil can be formed easily. SOLUTION: A double-pancake coil A is formed, in such a way that a coil wire rod 1 temporarily wound in a cylindrical state is divided into two parts at the middle section, and a first-layer coil section A1 is formed by drawing out one part of the wire rod 1 from the middle section to one end by changing the curvature of the wire rod 1 by means of a bending mechanism 33 and spirally winding the part, while the shape is maintained from the inner peripheral side in the same plane. When the formation of the first-layer coil section A1 is completed, the section A1 is inverted upside down and a second-layer coil section A2 is formed by winding the other part of the wire rod 1 from the middle section to the other end upon the first-layer coil section A1 while the shape is maintained from the inner peripheral side by similary changing the curvature of the wire rod 1. |
