Definitions

• the present invention relates to a method of crimping a stone into a metal element.
• an operator applies a tab, obliquely, to the surface of a piece of metal to deform it.
• the metal is deformed to form a collar which covers the periphery of the stone and immobilizes it on the metal element.
• Another drawback of this process is that it only allows stones to be set on elements of metals such as gold or silver, that is to say metals having a certain ductility.
• Another drawback of the current setting process is that, in the case of paving, that is to say a multitude of stones set next to each other on the surface of a jewel or watch, the area of metal which is bounded by the stones constitutes an area which appears as dark and does not contribute to highlight the stones.
• An object of the invention is therefore to provide a method for setting stones in a piece of hard metal, such as for example titanium.
• Another object of the invention is to propose a crimping process making it possible to enhance the set stones.
• this method of crimping at least one stone having a laminate in a piece of metal comprising the steps consisting in:
• the method according to the invention therefore makes it possible to crimp parts on an extremely hard metal thanks to the perpendicular action of a tool to deform the metal and form a lip.
• the impression forming a lip has at least one facet, which gives the crimping according to the invention an additional visual appeal.
• the application of the tool is done manually.
• the application of the tool is done mechanically.
• the invention also relates to a tool allowing the implementation of the method, having at its end at least one surface ending in a point.
• the tool can take:
• the tool has at its end a conical shape ending in a point.
• the tool has at its end a tetrahedral shape terminated by a point.
• the tool has at its end several facets converging towards a point.
• the tool has a radius of 0.2 to 0.5 mm.
• the invention also relates to the product such as a piece of jewelry or a timepiece comprising a metal piece on which is disposed at least one stone having a laminate, characterized in that it has, around at least one stone , at least one imprint having a facet imprinted in the surface of the metal stone forming a lip covering the laminate of the stone.
• the entire surface of the piece of metal delimited by several stones is imprinted in its entirety.
• Figure 4 shows, in top view, a product obtained by this process
• Figures 5 to 8 show several possible embodiments of tool for implementing the method according to the invention.
• Figure 1 shows, in section, a piece of metal 1 having a hole 2 as is well known in crimping techniques.
• This hole 2 comprises, on the side of the surface of the metal piece 1, a conical seat 3 and a cylindrical part 3. It may be noted that the conical seat 3 on which a stone will rest is located at a distance very close to the surface of the metal part 1, this distance possibly being from 0.1 to 0.2 millimeter.
• FIG. 2 represents the stone 5 placed in the hole 2 before the crimping step has started.
• Figure 2 the approach of a tool 6 in a direction perpendicular to the surface of the metal piece 1.
• the tool 6 shown has a conical end ending in a point 12.
• Figures 5 to 8 show several embodiments of the tool. These non-limiting embodiments have all in common, however, the characteristic that the end of the tool consists of a tip 12 at its end. This point 12 applied perpendicularly to the surface of the metal makes it possible to repel even the hardest metal to form a lip 8.
• FIG. 5 represents a tool whose end is pyramidal
• FIG. 6 represents a tool whose end is tetrahedral.
• FIG. 7 represents a tool whose end is conical
• Figure 8 shows a tool whose end has four facets.
• the method thus described, has many advantages. It makes it possible to set stones on an extremely hard metal, such as titanium, since the tool which is used to deform the metal and to form a lip coming to bear on the laminate of the stone, acts perpendicular to the surface of the piece of metal intended to receive the stones. In addition, the fact that the tool has an end which will give the impression a smooth surface allows an additional effect insofar as the impression which ensures the retention of the stone also achieves a reflection of light.
• Another advantage of the process according to the invention resides in the fact that it makes it possible to set stones on an interior surface or a left surface.
• the surface crimped by the method according to the invention has a continuous appearance which means that the crimped stones appear as aligned in rows and columns
