Definitions

  • the present invention concerns a process for the production of artefacts made of substantially flexible material, in one or more layers, and incorporating laminar elements of precious metals.
  • the invention concerns also articles realized with such artefacts, especially articles forming part of such sectors as fashion, leather goods and clothing, jewellery, furnishing and personal and environmental ornaments in general.
  • Another object of the present invention is to provide articles for use in the fashions sector, especially clothing and leather wear, jewellery and furnishing, realized in accordance with the process that constitutes the object of the invention.
  • the process envisages the use of decorative elements made of precious metal foils of minimal thickness to be applied to a flexible support.
  • the flexible support may be leather, leatherette or plastic material and must have a sufficient thickness to permit the formation on it of an impression capable of accommodating the decorative element, as will be explained in greater detail later on.
  • this thickness may be as little as 0.5 mm and may generally be of the order of 1 mm.
  • the precious metal to be preferentially employed is gold in its various chromatic gradations, but silver and platinum and alloys of these metals may also be advantageously used, always provided that they can be reduced to the thickness of a foil.
  • the first step consists of the lamination of a sheet of gold to the point where a foil of the requested thickness (down to 0,05 mm) is attained, passing through several intermediate and final annealing stages. Given its very small thickness, the foil obtained in this manner is of an inadequate consistency and, in accordance with an important characteristic of the present invention, the foil is then subjected to hammering to render it more robust and more plastic. To this end it was found that a hammer with a spherically shaped head proved particularly advantageous.
  • the foil is sheared to size to obtain decorative elements of the desired shape and the resulting elements are then deoxidised by means of known techniques and subjected to sanding to confer a satin appearance upon them, this treatment rendering them less liable to become damaged when they are brushed against during their subsequent use.
  • One or more attachment pins 4 is/are then applied to the face of each element opposite to the one that has been hammered to permit their being connected to the substrate, which is shown only in Figure 8.
  • the invention envisages two operating modalities.
  • impressions 2 having the same shape as the decorative elements to be applied, said impressions being produced by simply compressing the leather with the help of an appropriate punch. The bottom of each impression is then scratched to roughen its surface and this is followed by the application of a layer of glue to it. A decorative element is then introduced into each impression, after which the entire substrate is moderately heated to activate the glue. The fixing is obtained by means of the combined effect of the glue and the attachment pin that engages in the bottom of the impression. Impression 2 has a depth such as to assure that the decorative element 3, once it has been housed in the impression, will be perfectly flush with the surface of substrate 1.
  • the artefacts obtained in this manner may be preferably employed in the clothing and leather goods sectors for realizing articles that have substantially flat or moderately curved faces, cases in point being handbags, belts, footwear or articles of leather clothing, or also in the furnishing sector, where they can be used for realizing decorative panels, table articles and similar.
  • the artefacts can also be used for realizing articles with a small radius of curvature, bracelets being a case in point.
  • Figures 2-7 Another operating modality, alternative to the one just described, is schematically illustrated by Figures 2-7, which show the production steps for realizing a bracelet.
  • the product obtained is constituted by several layers of materials, which may also differ from each other, while the laminar decorative elements obtained as described above are arranged between them.
  • the laminar elements 3 are attached, one at a time and in accordance with a pre-established sequence, a particular possibility being the partial superposition shown in Figure 4, on carrier strips, for example on two such carrier strips, indicated in Figure 3 by the reference number 5, on which there have been arranged appropriate seatings that can engage with the various attachment pins 4 projecting from the face not in view of decorative laminar element 3.
  • Carrier strips 5, in their turn, are then applied to a tubular substrate 6 by means of gluing and in positions appropriately spaced with respect to each other.
  • Tubular substrate 6 is preferably made of leather and appropriately prepared for the desired function.
  • this preparation consists of conferring the desired shape upon the substrate by wetting it, forming it under pressure and then allowing it to dry.
  • a lining 10 is then applied to the inside face.
  • three further strips 7 of high-quality leather, crocodile skin for example, which for purely decorative reasons, as shown in the figures, may assume a wavy pattern.
  • a cladding consisting of a strip 9 of sapphires threaded on gold wire and anchored to the two strips 7 by means of sewing. The loose and open pattern of the sapphires makes it possible to glimpse the decoration of the leather beneath them.
  • the present invention envisages obtaining the laminar decorative elements by means of shearing of the metal foil, it is also possible to obtain the same result by means of laser cutting, a technique that, among others, implies smaller setting up costs and does not damage the surface hammering treatment.
  • the laminar decorative elements may also be provided with two or more attachment pins, all applied by means of welding as above.
  • the layout of the various strips and their number may vary according to the designer's fancy, but in each cases the golden laminar elements are arranged in such a way that their edges are covered by the adjacent strata.
  • the sapphire strips can also be replaced by strips of other precious stones or, alternatively, they can be omitted altogether or substituted by other decorative elements or motifs.
