Abstract

The method involves forming a first multi-lobed coil (C1), by winding a continuously fed wire (W) in a first direction. A second multi-lobed coil (C2) is axially superimposed on the first coil (C1), without cutting the wire being fed. The wire is wound in the opposite direction, while the second coil is arranged at a position angularly shifted relative to the first coil. Thus, the second coil (C2) has its lobes at the same angular positions of the hollows of the first coil (C1). The wire portion (W1) connecting the two coils (C1,C2) is bent where the wire reverses its winding direction. Such arrangement forms a loop (E) following an annular path matching the profile of one lobe of one of the two coils for one part and the profile of a hollow of the other coil opposite to the lobe for another part.
