Definitions
- the invention relates to a method for obtaining a link of patterns, and an object, in particular a jewel, com ⁇ carrying a link pattern.
- pattern link here means an object in one piece consisting of joined patterns, the mo ⁇ tifs being hollowed over their entire thickness in the places dictated by their design.
- the structural strength of the link is given by the connection between the acco ⁇ les motifs. This is not a simple engraving of motifs on a plate.
- Jewelery made of a chain of mo ⁇ tifs are known, for example bracelets containing a sequence of adjoining alphabetic characters representing a first name. These links are machined from a metal plate, or molded.
- the invention is more particularly concerned with the links of small patterns (of the order of a few millimeters). For such small sizes, the machining of motif links is very difficult. In addition, the molding of patterns as thin as lost wax is impossible.
- the subject of the invention is a process for obtaining chain links that can be implemented in a very economical manner and that can be used for the production of any chain of patterns.
- the invention also relates to an object, in particular a jewel, comprising a link of patterns.
- the invention proposes a process for obtaining a chain of patterns comprising the steps of: digging into a solid mass an imprint comprising a series of patterns contiguous to one another;
- the male form thus stiffened is thus made easily manipulable.
- the rigidification of the sequence of patterns makes it possible to mold the pattern suite, including lost wax. It is then possible to make metal pattern links of very low height.
- the step of stiffening comprises the operation of associating a sole after the patterns (11) so that it forms with the sole a male shape in which the pattern suite extends in relief of the sole.
- the sole stiffens the pattern sequence of the male form.
- the sole facilitates the injection of liquid material in the mold formed around the male shape by providing the possibility of providing one or more feed points at the sole.
- the molding of the male form leads to a link of patterns extending in relief from a base, the base being at least partially leveled.
- the base being at least partially leveled.
- the impression material is chosen to provide a series of deformable patterns and the stiffening step comprises the defor ⁇ mer operation following the patterns to come next to the edges of the sequence of patterns and join these edges en ⁇ them.
- the result pattern thus worked forms a rigid male shape that can be easily molded.
- the deformation comprises the oper ⁇ tion of winding the sequence of spiral contiguous patterns, the facing edges being secured to each other.

- the method of the invention comprises the step of digging a footprint 2 in a solid mass, here a plate 1 cut in an acetate sheet of 2 millimeters thick.
- the plate 1 has a width of about 8 millimeters.
- the impression 2 comprises a series of alpha ⁇ betic patterns which are joined to each other so as to overlap slightly.
- the sequence of patterns is obtained by etching the plate 1 by means of an etching tool 3 (here a ball-end mill with a diameter of 0.6 millimeters) moved by a computer 100 on which a program can generate the path of the gra ⁇ vage tool 3 from a series of patterns, here letters typed on the keyboard of the computer 100.
- the patterns have a height of 3 millimeters.
- the plate 1 is positioned in a jig 4 having a hollow 5 which is deeper than the thickness of the plate 1.
- the imprint of the plate 1 is coated with a product the
- demolding for example a silicone oil.
- a wax strip 6 is applied to the plate 1, for example wax used in the manufacture of dental prostheses, which has previously been softened by light heating.
- the wax strip 6 has a thickness such that it exceeds the upper surface of the jig 4.
- this wax strip 6 is covered with a sheet of paper 7, then the wax strip 6 is pressed into the cavity 2, for example by rolling on the upper surface of the template. 2 a cylinder 8.
- the wax 6 then enters the cavity 2, while forming a sole delimited in thickness by the upper surface of the plate 1 and the upper surface of the jig 4 on which the cylinder 8 rolls.
- the flanks 9 of the recess 5 (visible in FIG. 2) form a mold for said soleplate.
- the preceding operation made it possible to obtain a male form 10 made of wax comprising a series of patterns 11 in relief projecting from a sole 12.
- the sheet 7 adhered to the se ⁇ melle 12 during the pressing operation, which allows the easy extraction of the male form 10 of the template 4. It is then sufficient to peel the sheet of paper 7 to separate it from the male form 10, as illustrated.
- the male shape thus obtained is sufficiently ri ⁇ gide to be easily manipulated and molded. Then, in a manner known per se, the male form thus obtained is molded, preferably by the lost-wax molding technique.
- the material used for the molding may for example be silver, or 1Or.
- the sole 12 reserves in the mold a space that allows to arrange several feeding points, faci ⁇ greatly reading the molding of such small reasons.
- the base 16 has been leveled, for example by milling, leaving only the link of patterns 15 forming an alternation of valleys and solids.
- This link pattern can be used as is, for example to make jewelry. Nevertheless, because of its small size, it is relatively fragile. It is then interesting to stiffen such a link of motives.
- two portions of links joined together by one of their edges are molded together.
- Resulting seen in Figure 6 one molding having two portions membered patterns 20,21 joined together at their edges, which has been leveled the common base.
- Each of the link portions of patterns forms a stiffening support for the other portion of the link of patterns, so that this double link is much more rigid than a single link.
- the plate 1 is hollowed out so as to provide a recess which extends along one of the edges of the series of patterns 2. hollow makes it possible to mold the stiffening support di ⁇ rectly with the link pattern.
- the pattern link 40 is formed in a contiguous spiral, and the turns of the spiral thus formed are welded edge to edge.
- weld points 41 only one is referenced which are made by the rear face of the link, and therefore invisible from the outside. This gives a particularly aesthetic ring.
- the method of the invention comprises the step of digging a cavity 202 in a solid mass, here a plate 201 of wax, which has the advantage of being remelted after use.
- a plate 201 of wax which has the advantage of being remelted after use.
- the use of wax for the solid has the further advantage of allowing very fast machining.
- the imprint 202 comprises a series of al ⁇ phabetic patterns which are contiguous to each other so as to slightly overlap.
- the pattern sequence is obte ⁇ nue, in the same way as before, by etching the plate 201.
- a fluid resin 206 for example a polyurethane resin
- the spray is sprayed on a spray of silicone bomb promoting demolding.
- the mold is demolded and a series of patterns 211 as shown in FIG. 10 is obtained.
- the plate 201 can be deformed slightly, even if the mold is difficult to demold. , raise the plate temperature for di ⁇ later slightly.
- the pattern suite 211 is spirally wound around a cylindrical template 230 so as to have contiguous edges.
- the chosen resin is of the flexible type in the solid state, so that the pattern suite 211 is easily deformable.
- the contiguous edges of the sequence of patterns 211 are glued, for example using cyanolite glue 220.
- a male shape 210 is thus more particularly visible in FIG. 12, much more rigid than the series of patterns 211, and easily manipulable.
- the male form 210 is immersed in a solvent bath to remove excess glue. It then remains to mold the male form 210, preferably by lost-wax molding, to directly obtain a metal ring made of a spiral-wound pattern of links to the contiguous edges joined together by mou ⁇ lage.
- the jewel obtained is very solid and does not have the inherent weaknesses of welds or collages used in the previous implementation mode.
- the method of the invention therefore comprises the step of realizing an intermediate, in this case the male form, which comprises a series of stiffened units to allow its handling and molding .
- the stiffification is here obtained by the production of a sole, or by the shaping of the sequence of spiral patterns and solidification of the edges.
- the invention is however not limited to these types of stiffening, and any other stiffening may be envisaged, such as for example the bonding of a plastic plate on the back of a series of patterns obtained by casting liquid resin. in the imprint.
- the impression made in the acetate plate is not through, allowing a rounded finish ⁇ tion of the edges of the patterns using a tool of engraving rounded end, we can of course ré ⁇ aliser a through impression, the wax then ar ⁇ rêtée by the bottom of the hollow of the jig.
- the solid is a plate cut from an acetate sheet, any other material such as an aluminum block may be used. It will also be possible to use a microperforated plate, to allow air trapped by the wax band to escape when the wax strip is pressed into the cavity.
- the molding base was total- leveled to obtain a linkage of patterns whose structural strength is only due to the connection between. the reasons, we can be content to partially level the base to leave a veil under the grounds. It will still be possible, although less satisfactory from an aesthetic point of view, to leave the base.
- the bond between the metal molded pattern link and the stiffening support is obtained either directly by molding or by means of welding points, a continuous weld can be produced. along the edge, or use other means of connection, such as a collage.
- the patterns presented are letters, it will of course be possible to reproduce patterns other than letters, the patterns being preferably chosen from a pattern base, which makes it possible to rapidly determine the sequence of patterns to be reproduced.
- the impression can also be obtained by other means, for example by photoengraving or else by embedding in a malleable material punches each forming a specific pattern.
- any other material capable of filling the footprint of the massif may be used, such as curable sealant.
