Abstract

The invention relates to a machine for making ornamental chains consisting of a plurality of interconnected links starting from a metal wire. Said machine comprises a working station (10) into which the metal wire is fed and in which at least one pliers (1; 1') moves said metal wire according to a combination of rotational and/or translational movements necessary to obtain the desired link. According to the invention, the pliers holder (3; 3') holding said pliers is at least partially controlled by an electronic driving mechanism with electronic cam determining, at each instant, the position of said pliers holder in order to obtain the desired combination of movements. Thanks to the invention, the features of the link obtainable with said machine can be varied without physically intervening onto the machine itself, and the variety of links obtainable with said machine is enormously increased.

Abstract

The present invention relates to a method for making a chain link for jewellery and goldsmith's applications, comprising the steps of cutting out a template (201) from a flat metal strap (401), wherein the template has a direction of extension (209 ) that defines two ends (208) thereof, shearing (403 ) passage slots (204) in the template, half - shearing (407 ) junction prongs (203) on the template, bending the junction prongs outwards from said link, and bending the template to match the two ends together. The present invention also relates to a chain link and to a device for making it.
