<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a band-shaped iron core piece to be used for a wound laminated iron core that manufactures a plurality of band-shaped iron core pieces from a sheet of thin strip material without interference. <P>SOLUTION: A manufacturing method of a band-shaped iron core piece used for a wound laminated iron core 45 comprises: forming band-shaped iron core pieces 11, 12 in multi lines on one strip of a thin strip material 10, the band-shaped iron core pieces 11, 12 consisting of segment iron core pieces 17, 18 having one or a plurality of magnetic pole pieces 15, 16 and connected at connection parts 19, 20; separating the multi-line band-shaped iron core pieces 11, 12 from each other; and sequentially folding the band-shaped iron core pieces 11, 12 at the connection parts 19, 20 to make the wound laminated iron core 45. The multi-line band-shaped iron core pieces 11, 12 are formed with positions of the connection parts 19, 20 arranged in the travel direction of the thin strip material 10, and the band-shaped iron core pieces 11, 12 adjacent to each other in the width direction of the thin strip material 10 are connected to each other with connection members 27. The connection members 27 are cut off when separating the multi-line band-shaped iron core pieces 11, 12 from each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
