FR2853665A1 - Decorative or structural layered material manufacturing procedure e.g. for leather consists of gluing and compressing layers and then sculpting - Google Patents

Abstract

The procedure consists of gluing together and compressing a number of different-colored layers (1, 2, 3) of a supple material such as leather and then cutting through at least the first layer to reveal other colors beneath. The cutting can be carried out with a sculptor's gouge or a computer-controlled tool for serial production.

Description

Laminate worked in the mass

  The present invention relates to a principle which can be applied to any material, flexible, fine, and which can be easily cut. One of the most suitable materials is leather. the following description takes as an example the application of the principle on the leather material.

  The present invention relates to a technical and decorative principle making it possible to work the leather material in the mass and to apply to it at the same time an original decorative effect, thanks to the superposition of several layers of leather (fig. 1) laminated between In general, leather is more commonly used as a coating on furniture or an object. It is used to dress a structure on which it is a cheerful element.

  The aim of this invention is to offer new technical, mechanical, and decorative properties to the leather material, and to open up its field of application by working it in bulk.

  By this principle, leather becomes, no longer a coating, but a structuring element in its own right.

  The technique of superimposing layers of leather makes it possible to reinforce the rigidity and the solidity of the material. The accumulation of layers of leather, independently flexible and thin, provides a more or less dense, rigid, and solid mass depending on the thickness. (The greater the thickness 25, the more these characteristics are increased.) According to a preferred embodiment, the leather used will be goat (morocco, mysore goat) and the different layers will be laminated with white vinyl glue and then kept in press. at least for twelve hours.

  The leather material thus appears in a new form and can be worked differently.

  It no longer comes in the form of supple and thin skin, but becomes massive and dense.

  These new discovered features open up the field of application to this material. Its new density allows it to be turned, sculpted ... just like wood.

  The advantage of this principle is that this superposition technique also allows an original decorative effect. On this idea, the decorative effect and the material are not dissociated. The decorative effect can be, at the same time, the structuring element. We could go so far as to say that the material can itself be decorative.

  Indeed, the interest is to come to cut on the surface of this superposition of layers of leather, thanks to a cutting tool, to a depth at least equal to the thickness of the first layer in order to reveal the next layer located just below. (fig.3) According to a preferred embodiment, the tool used may be a sculptor's gouge. The curved shape of this tool increases the quality of the decorative effect of the technique.

  There are several forms of gouge each bringing a specific advantage to the decorative effect.

  The tool cuts the first layer of leather. The color of the second layer just below is revealed. A gradation of color will appear. (Fig.4) If you cut deeper, you will reveal the color of the third or fourth layer of leather. So with each stroke of the gouge a different color is revealed. On the same surface you can get a multitude of colorful proposals.

  The pressure exerted on the tool, the direction that we will give it will directly influence the aesthetics of the decor. We can cut along straight and parallel lines, we can cross these lines, we can make small independent and randomly placed cuts. The decorative choices are not limited.

  To obtain an interesting decorative effect, it is preferable to vary the colors and that two layers of juxtaposed leathers are of different colors.

  Example 1: leather 1 ----- color 1 leather 2 ----- color 2 leather 3 ----- color 3 leather 4 ----- color 4 leather 5 ----- color 5 The principle has the advantage of offering unlimited colored effects. We can use the number of colors we want, in the order we want. 25 It can be a set of two colors on five layers: Example 2: leather I ----- color 1 leather 2 ----- color 2 leather 3 ----- color 1 leather 4 ----- color 2 leather 5 ---- color 1 You can also create a camaieu playing on the same colored range or opt for clear contrasts between colors.

  The decor can, on the contrary, be monochrome.

  You can also play on the different thicknesses of the leathers and thus create other decorative effects.

  By this principle, laminating requires a restricted number of layers (two minimum). The decorative laminate thus obtained can therefore be flexible, flexible and can, for example, be used as a textile in the field of fashion (clothing, bags, shoes).

  This random technique, resulting from necessarily different gestures each time, gives the object that benefits from it an original, unique, hand-worked appearance.

  However, this principle can also be applied to industrial production where the manual gesture will be replaced by the digital tool.

  Thus, the object can be thought of either as a single piece, in small, medium or large series.

  This principle can be used in different fields of application (furniture, small objects, decoration, floor or wall covering ...) and in many ways: A colorful decoration will appear on the edges, "in leather".

  One can imagine a mass of leather obtained thanks to the principle of superposition in which one starts the material so as to reveal the colored play.

  The sculpted leather plates can be applied directly to a structure, by col1 0 lage.

  The laminating of leather cut in its thickness, in a very fine way, allows to obtain a "leather veneer".

  The colored strata are then compared to the threads of the wood.

  By this principle, the decorations exploited in cabinetmaking, such as, crimping in connection, in development, in sun ... are possible with the leather material.

  This layering technique also allows the bending of the leather.

  The leathers are laminated on a mold and keep the defined shape.

  This allows us to imagine different applications using curves where the leather material will be the only structuring element. By this principle, with a relatively thin thickness (superposition of two or three layers, for example) we obtain a certain rigidity.

  The density of a bonded leather plate is close to that of a wooden board.

  Thus, it is possible to transfer to leather the assemblies usually intended for wood such as dovetails, straight tails, mortise-tenon, tongue groove ... still respecting this work in mass and announcing new formal typologies for, for example for example, leather furniture.

Claims (8)

claims   1) Method for obtaining a decorative or structuring laminate, characterized in that it consists in laminating together different flexible and relatively thin layers of a material corresponding to these characteristics, then in cutting at least the first layer.   2) Method according to claim 1 characterized in that the laminate is made, preferably, of leather.   3) Process for obtaining a decorative or structuring laminate according to claim 1 10 characterized in that the layers are put under press after bonding.   4) A method of obtaining a decorative or structuring laminate according to claim 1 characterized in that the notching is preferably done using a sculptor's gouge or can be achieved by a digital tool controlled by computer, 15 for mass production.   5) Process for obtaining a laminate obtained according to the preceding claims, characterized in that at least certain layers are of different colors in order to obtain a more interesting decorative effect. 20 6) decorative laminate obtained by the method according to the preceding claims characterized in that it can be used just like textiles, especially in the field of fashion (clothing, bags, shoes ...) 7) Decorative laminate obtained by the method according to claims 1 to 5 characterized in that it can cover any structure whatsoever.
