Abstract (en)
The present invention relates to a method for making a chain link for jewelry and goldsmith's applications, comprising the steps of: cutting (202, 203, 205, 206) an outline (207, 601) from a flat metal strap (101), the outline (207, 601) having a main development direction (501) that defines two ends (502, 503) thereof, wherein the outline comprises at least two junction tines (602, 603), each one situated at a respective one of the two ends (502, 503), the junction tines being arranged on the flat metal strap (101) in a direction transversal to the main development direction (501); bending (301, 302) the at least two junction tines (602, 603) to bring them on respective bending planes which are transversal to the plane of the flat metal strap (101); bending (303, 304) the outline (401, 701) along at least one bending line which is transversal to the main development direction (501), thus placing the two ends (502, 503) against each other to close the link (701), wherein the junction tines (602, 603) face outwards from said link (701). The present invention also concerns a related chain link, a related chain, and a related device for making a chain link.
