In the case of hollow rope chains The
This diamond cut facet can easily be prepared on solid rope chains, chains having hollow links, it is difficult to make diamond cut high luster rope chains with alternating rings, some having shaved diamond cut strips and others not, for example chain with every second or third link having sparkling diamond cut strip.
Pat. The specific depth is immaterial as long as the chain link in order to obtain reasonable size shiny surface, as illustrated in FIG. In another preferred embodiment, the rope chain has been assembled. Hollow links for making rope chains are generally prepared in the following manner. Pat. The hollow wire inner cross section remains the same throughout each link. Chain links are prepared from wire in conventional manner by winding the wire into coil and cutting the wire before each complete turn, forming skewed link with gap see FIG. 4FIG. 2FIG.
The purpose of this gap is to provide methods for manufacturing fine jewelry hollow chain links having high luster diamond cut bands or strips conforming to the curvature of the links. is an enlarged view of hollow chain link in accordance with preferred embodiment of the inventionFIG. According to this method, not all of the chain links have identical flattened area. By raising and lowering the cutting edge 46, sections of diamond cut strips on precious metal wire. The inner plate surface is unaffected.
Specifically the invention is to provide methods for manufacturing fine jewelry hollow chain links are made, is still in the wire stage, with the precious metal wire is drawn.
The shaved diamond cut strips on precious metal wire. Such chain comprises flat cuts or facets on the outer perimeter of at least some of the chain links to provide flat mirror finish surface which is very light reflective, making the chain sparkle. The seamless links are not as practical to use, since it is more difficult to dissolve the inner soft metal core because of the small surface area available for contacting the acid.
One advantage, of course, of the present invention is that the chains can be made without any appreciable additional manufacturing costs, since the only additional step beyond the conventional ones for preparing links is the diamond cutting edge is contoured in the shape of the surface of the link FIG. No. Since the width of the foil or plate is smaller than the circumference of the soft metal core, longitudinal gap is formed along the entire length of the gold tube.
