ABSTRACT:
A method of forming hollow link, facetted chain and the chain formed by the method. The method begins with chain assembled from hollow links having outer wall regions, which links are already soldered together. Generally flattened facets are formed on the hollow link chain by passing the hollow link chain along a longitudinal path, wherein a series of rotating anvils deform inwardly portions of the outer wall regions to thereby form generally flattened facets on at least some of the hollow links to form the hollow link facetted chain.
