Abstract
A process for making a jewelry article, in particular a bracelet, which first includes a step of arranging an elongated support (6). A step of forming an ornamental wire (5) comprising an internal core (3) made of a non-precious material and an external strip wound in a precious material is then carried out. Such an ornamental wire is then wound around the elongated support (6) to form a cord of ornamental wires made of a precious material. Such a cord is then emptied of the internal cores of the ornamental wires and of the elongated support following a first and a second removal step. It is then cut in several points to form sections which will become the finished product.

Process for making a jewelry article, comprising the following operating steps:
- a step of arranging an elongated support (6), stretched between two ends along a longitudinal extension direction (Y);
- a step of making at least one ornamental wire (5) by means of covering at least one internal core (3), made of a first metallic material, with at least one external strip (4) made of a first precious or semi-precious metallic material;
- a step of spiral-winding said ornamental wire (5) around said elongated support (6) along said longitudinal extension direction (Y), in order to obtain a solid cord (15);
- a first step of removing said elongated support (6) from said solid cord (15);
- a second step of removing said internal core (3) from the ornamental wire (5) of said solid cord (15);
- said first removal step and said second removal ep transforming said solid cord (15) into a lightened cord (18);
- wherein said step of making said ornamental wire (5) is obtained by feeding a forming head (2) with said internal core (3) and with said external strip (4), which is provided with a flattened form with parallel longitudinal edges (4′), said making step covering said internal core (3) with said external strip (4) until said longitudinal edges (4′) are side-by-side in opposite position and separated from each other by a slit (4″) on a flat face (5′) of said ornamental wire (5);
- said spiral-winding step being achieved by maintaining the flat face (5′) of said ornamental wire (5) directed towards said elongated support (6).
Jewelry article, comprising a cord provided with at least one ornamental wire (5) made of a first precious or semi-precious material with spiral-winding along an extension direction (Y),
- wherein said cord is provided with an annular hole arranged coaxially with the spiral winding of said ornamental wire (5) and that said wire has an open-ring transverse section with a flat face (5′) directed towards said longitudinal axis (Y) and formed by two adjacent flaps, externally connected by a convex portion and terminating with two parallel longitudinal edges (4′) delimiting a slit (4″) placed at said flat face (5′).
