COIL MANUFACTURING METHOD, AND COIL MANUFACTURING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a coil manufacturing method, and a coil manufacturing system that can easily and efficiently manufacture coils.SOLUTION: A coil 20 is manufactured through a spiraling step of forming a drum shaped spiral body (spiral body) 20a by winding a wire rod 10 spirally, a shortening step of shortening the drum-shaped spiral body 20a along its winding center axis CL1, and a shape retaining step of keeping the drum-shaped body 20a in shortened state.
