Abstract: The invention relates to the art field of machines for the manufacture of jewelry, and has as its object the embodiment of a machine and the provision of a method that will permit embellishing precoined metal strip, using either continuous stock or discrete lengths. Such a machine makes use of a support on which to position the strip, a packing medium with which to bolster the coined imprints and protect the support, a method for tensioning the strip, and tools, and enables crafting of the embellishment quickly and economically by virtue of the design of the support, which is substantially circular, split into identical and symmetrical halves, and composed of a base and an intermediate layer. This intermediate layer is embodied in an insulating material, and incorporates open-topped channels which accommodate small-bore tube for the circulation of refrigerant and is covered over by a permeable barrier strip.

Abstract: A method and apparatus for automatic shaping and/or decoration of longitudinal members in modular units of preset size, such as wire, tube, flat strip or linked pressings, from which ultimately to fashion articles of jewelry in precious metal or articles of costume jewelry, featuring the following steps: two-point support, tensioning and guiding of a longitudinal member through and along its own longitudinal axis; shaping/decoration of a stretch of the longitudinal member lying between the supports, at points located in opposition either side of a longitudinal median plane; and linear and/or rotational movement of the longitudinal member along and/or about its own longitudinal axis relative to means which carry out such shaping or decoration.
