Procedure for producing an ornamental chain

Abstract

A procedure for making ornamental chains that can be used in the area of jewelry and costume jewelry, consisting of soldered rings that are reciprocally concatenated and forming a chain that provides different aesthetic looks depending on the soldering and the type of concatenation of the rings themselves. The procedure is characterized by the fact that the meshes of chains are formed by at least two portions or semi-rings, that are coated to form the concatenation and thus reciprocally soldered along their corresponding coinciding extremities.

Description

DESCRIPTION

[0001] The present find concerns a procedure for the production of ornamental chains, but not only those chains produced with said procedure.

[0002] It is well noted that one of the methods of chain production employed in the areas of jewelry and costume jewelry consist of the making of small molded rings, The type that are concatenated in succession together, making a chain that presents diverse esthetic aspects according to the molding and type of concatenation.

[0003] The single rings are made by semi-formed tubes, consisting of a core of iron, copper, and other none noble metals, necessary, in order to allow folding without deforming these same rings, which will be re-dressed with a laminate of noble material.

[0004] The wire thus becomes successively formed, folded into a spiral model on a spine of circular shape, oval or of other geometric forms, the transversal section corresponds in internal length with the rings of the chain that is produced.

[0005] In time, this spiral becomes sawed longitudinally, in such a way to obtain single rings that are extreme opposites, slightly open, in order for them to be concatenated together in order to form a chain.

[0006] In time, the rings become closed again, and individually soldered at the extreme opposite point of the seam.

[0007] The chains are then placed in contact with aggressive substances such as hydrochloric acid, nitric acid, caustic soda and others that dissolve, by way of a corrosive process, the core of the internal metal of the single rings.

[0008] The unwrapping of the corrosive metal core occurs through openings present on the noble metal laminate, that are defined by the longitudinal seams and delineated by the border but not perfectly coated by the laminate itself or when the tubular form becomes soldered by way of windowed openings in the internal thickness of the laminate itself.

[0009] The purpose of this finding is to provide a procedure for producing ornate chains in a simplified way.

[0010] One can see that the chains are made from rings, in fact, from a single, tubular body folded and then soldered at the extreme ends of the seams, two portions or partial rings, reciprocally soldered, in there extremity, closely together.

[0011] With the following constructive solutions, it is possible, with the application of sophisticated soldering methods, already in use, for example, to use laser, with its numerous operative and esthetic advantages.

[0012] From an operative point of view, the first and most important advantage is its ability to make completely new chains with meshes without industrial equipment of the type noted.

[0013] In fact, it is easily sensed, that the making of rings by way of a reciprocal soldering of the two opposite parts does not make it necessary, any longer, to assume a substantial ring conformity or symmetry, consequently, making one form.

[0014] In fact, thanks to the ability of molding separately each of the two parts before their reciprocal soldering, it is possible to obtain closed rings, reciprocally concatenated, where we can look back at the asymmetry of not only a single ring but also the entire mesh that makes up the chain, thus producing different, varying forms of rings and chains.

[0015] Always from an operational point of view, an ultimate and no less important advantage derives from the fact that the semi-rings, when reciprocally soldered, are advantageously empty of the internal, metal core, from which, once soldered, it becomes no longer necessary to expose the chain to corrosive chemicals, this is a noted cost savings to the entire production cycle.

[0016] This is possible since most of the single, semi-rings were re-folded and have since assumed a defined shape, they become exposed to the aggressive, corrosive substances, the unwrapping of the core occurs naturally, from the tubular body, thus eliminating a work cycle in which laminates are needed to close superficial openings in noble materials.

[0017] From an esthetic point of view, the advantages are the ability to make ornamental chains that present conformity of the meshes already noted and are examples of gourmette, herringbone, triple, quadruple, quintuple and others, whereby, however, the single rings can be bi-color or composed of two diverse metals.

[0018] The ultimate characteristics and advantages of this find can be seen more evident by means of describing some of the preferred forms, rendering only sample illustrative titles and not limited, with the help of the design tables attached:

[0019] FIG. 1 represents the phase of chain production with the newly discovered procedure

[0020] FIG. 2 represents some possible types of ring forms obtained with the discovered procedure

[0021] FIG. 3 represents some possible types of ornamental ring forms obtained with the discovered procedure.

[0022] One can visibly see in FIG. 1 that each ring 1 is made up of two parts or semi-rings 2″ by 2″, that first coincide with the extreme, respective opposite to become concatenated and in time become reciprocally soldered along the aforementioned extremity.

[0023] It is visible in FIGS. 2 and 3 that with the new process it is possible to make totally asymmetrical rings and thus chains of unique esthetic appeal.

[0024] Obviously the procedure for this new find is as valid, the same, when applied to filled, semi-rings or with rings made up of more than two parts, as such, it is possible for these molds, which are different from the one's described, by alternating the concatenation of the rings from which one discovers diverse shapes, and the function of the esthetic that one wants to capture, will come out and be claimed in definitively in time.
