Abstract

Several methods of forming links for use with the creation of rope chains is disclosed, whereby the outer peripheries of such links are contoured prior to assembly into rope chains. In one embodiment, the wire used in the formation of intertwinable links is contoured and then cut into individual, pre-contoured links. In another embodiment, the outer periphery of non-contoured links are individually contoured prior to the intertwining of such links to form actual rope chains. In another embodiment, individual links are collectively contoured, preferably after arrangement on a support such as a mandril. Such contouring can be accomplished by hand, machine or the like.

Claims (15)

1. A method of producing chain links suitable for use in making jewelry chains comprising the steps of:

a) providing at least one chain link having an inner periphery, an outer periphery and a thickness,

b) providing a mandril having an outer periphery,

c) arranging said at least one chain link on said mandril, and

d) contouring the outer periphery of said at least one chain link while said at least one chain link is arranged on said mandril,

e) said contouring comprising the creation of X number of facets disposed around said outer periphery of said at least one chain link, X having a value that is greater than 8.

2. A method in accordance with claim 1 , wherein said contouring occurs by multiple passes of a contouring apparatus, each pass resulting in the creation of at least two facets.

3. A method in accordance with claim 1 , wherein said contouring further comprises the application of a plurality of deformers against the outer periphery of said at least one chain link.

4. A method in accordance with claim 3 , wherein said plurality of deformers are single edge deformers.

5. A method in accordance with claim 3 , wherein said plurality of deformers are multiple edge deformers.

6. A method in accordance with claim 3 , wherein said plurality of deformers further comprise a combination of single edge and multiple edge deformers.

7. A method in accordance with claim 3 , wherein at least one of said plurality of deformers has a straight edge.

8. A method in accordance with claim 3 , wherein at least one of said plurality of deformers has a curved edge.

9. A method in accordance with claim 1 , wherein said at least one chain link is formed from hollow wire.

10. A method in accordance with claim 1 , wherein said at least one chain link is formed from solid wire.
