ABSTRACT:
A strip (1) is formed by lamination with diffusion, having two longitudinal bands (1A; 1B) of two different metals and two additional thicknesses (1E and 1F) bonded to the metals of said two bands (1A; 1B); the resulting strip is shaped by drawing it into a wire of circular section with a longitudinal slit (13), with said two longitudinal bands (1A, 1B) of different metals on the outside; said wire is wound into a helix, with the slit (13) on the inside of the turns, and the helix is then cut to form pieces (111) in the form of twisted open rings; said twisted pieces are formed into a chain of soldered and twisted links with the orientation of each of said two bands of each link on the same side of the chain, so that it shows two colors.
