<p>Starting with a helical chain of large links, of the type known as a "transverse figure-of-eight chain" or "transversely assembled figure-of-eight chain" that can be made by machine, after a preliminary twisting operation in which it is reduced to the general form of a strip with rounded edges, that is to say in the so-called "linx" chain configuration, a further deformation is carried out by swaging it in the direction of the greatest dimension of its cross section, in such a way that its cross section is deformed into a generally square figure.</p> |
