Abstract: The invention relates to a method of wrapping a spool with metal ribbon, as well as to the spool and to the ribbon designed to carry out the method. The method is particularly characterized by the fact that, while the ribbon (12) is still being profiled only transversely, it is first kept tangent to the band (7) of flanges (4), then, as it is being deformed elastically, it is wound progressively and, as winding proceeds, the edges are fixed on said binding (7) of the flanges (4) by applying stresses on the median portion in such a way as to cause it to bulge outwardly.
