  • Publication number: 20020093413
    Abstract: An electric coil is formed of alternate strip parts and remaining strip parts. The alternate strip parts comprise alternate ones among a row of strip parts formed from a sheet of electrical conductor material, the row of strip parts forming a continuous electrical conductor having a form of a series of alternating reverse directional bends, a middle part of each strip part of the alternate strip parts being aligned with one another in a first line. The remaining strip parts comprise remaining ones among the row of strip parts, a middle part of each part of the remaining strip parts being aligned with one another in a second line separated from the first line. In manufacturing the electric coil, a forming member is used. The forming member has comb teeth, the comb teeth of the forming member being used to press and thus separate the middle part of each strip part of the alternate strip parts from the middle part of each strip part of the remaining strip parts.
