Title: Winding device
Inventor: MIYAZAKI HIROSHI
IPC: H01F41/06
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To provide good aligning condition for the wire of an aligning coil. SOLUTION: A wire 12 is wound around a part to be wound of a spool 28 after alignment to form a coil having a shape meeting the part to be wound. A line change press apparatus 22 serving as a line change forming means forms a stage-difference line change part at a part on the wire 12 serving as a line change part moving from one line to another when the wire is wound around the part to be wound. The stage-difference-shaped line changing part is formed by molding the wire without performing a line change for the wire as it goes, therefore the influence of winding tension force or the like is reduced to align the wire regularly. It is more applicable to form a line change part either before the wire is wound and while the wire is being wound.
