1. An Apparatus for forming a woven coil assembly, the coil assembly having adjacent superimposed linear portions extending parallel to each other in a first area of the coil assembly, and adjacent superimposed linear portions extending parallel to each other in a second area of the coil assembly, wherein a plurality of turn portions connect the linear portions of the first area to the linear portions of the second area, the apparatus comprising:
a first holding device located at a first position along a feeding direction of a plurality of conductors, the first holding device being arranged to hold the conductors in a plurality of seats, each of the plurality of seats receiving a respective conductor;
a second holding device located at a second position along a feeding direction of a plurality of conductors, the second holding device is arranged to hold the conductors in a plurality of seats, each of the plurality of seats receiving a respective conductor, wherein the second holding device is configured for moving in a transverse direction with respect to the first holding device to form inclined portions of conductors between the first holding device and the second holding device; and
a plate for bending provided with a bending edge positioned transversally and perpendicularly to the feeding direction, wherein the second holding device is configured for rotating a portion of conductors around the bending edge in a rotation direction, and wherein during the rotation, the bending edge engages the inclined portions transversally and perpendicularly to the feeding direction.
