SUBSTANCE: pair of guide elements (65, 66) with the shape of disks is adjacent to the end surfaces of conducting wire (61) that are opposite to axis (L), at that the wire is wound in coil with application of detachable assembling accessory. Guide elements (65, 66) are spring-loaded in direction to each other by means of fixation of part of conducting wire (61) to the coupling elements (65c, 66c), which are arranged along circumference of pair of guide elements (65, 66). Then assembling accessory is removed from the center of conducting wire (61), at that shape of coil without frame is maintained (46), in which internal peripheral surface of conducting wire (61) is opened. Additionally pair of guide elements (65, 66), which have shape of disks, is spring-loaded in direction to each other by means of conducting wire (61) and, accordingly, there is no need in special spring element.
