Abstract (en)
[origin: EP0439389A1] The present invention relates to a method of making electromagnetic coils, each including a plurality of flat turns laid side by side. According to the invention: - a plurality of patterns (101, 201) is cut out from a sheet (100, 200) of electrically conducting material, each of the said patterns representing the flat development of a coil and forming a strip containing a plurality of open loops (102, 202) connected to one another, at their ends, by connecting bridges (105, 205), and intended to constitute the turns of the said coil, - the strips (101, 201) of the said sheet (100, 200) are separated, and - the loops (102, 202) of each strip (101, 201) are folded over one another in zigzag fashion so as to form the said coil.
