Abstract
Links suitable for use in assembling rope chains are produced by utilizing a progressive series of punch and die sets which pierce and blank such links from a sheet of metal. If the metal sheet is in a long strip, the strip can be incrementally advanced through multiple series of punch and die sets so that several links can be created simultaneously. Because the links are die cut or stamped, the shape of the link can be arbitrary and can be a straight sided polygon such as a square, hexagon or octagon, or may be curvilinear such as a circle.
