Abstract
For forming a cylindrical coil (3) on a rectilinear arm of a magnetic circuit (1) having a very small air-gap (2), a wire guide member (6) has a wire inlet portion (8), a wire outlet portion (9) and an elongated intermediary portion (11) arranged for effecting a rotary movement about the axis (4) of the coil (3) and a reciprocating movement in the axial direction of the coil (3). The intermediary portion of the wire guide member has, over a length at least equal to that of the coil to be formed, a height smaller than the length of the air-gap so that it can move through the air-gap in the longitudinal and in the transverse directions.
