Multi-layer material and relative method of production

1. A multi-layer material comprising:

a plurality of wood-based sheets, wherein the plurality of wood-based sheets include one or more internal wood-based sheets and one or more external wood-based sheets;

a layer of metal material interposed between at least two wood-based sheets among the plurality of wood based sheets;

wherein at least one of the internal wood-based sheets has a progressive reduction of thickness towards its ends and terminates in a position upstream with respect to the ends of adjacent internal wood-based sheets and external wood-based sheets, and

wherein a shorter length of the at least one of the internal wood-based sheet determines the progressive reduction and a corresponding variation of an overall thickness in the multi-layer material.

2. The multi-layer material as in claim 1 , wherein the layer of metal material includes a first layer interposed between the at least two wood-based sheets and a second layer interposed between at least two different wood-based sheets.

3. The multi-layer material as in claim 1 , wherein the layer of metal material includes a first layer interposed between the at least two wood-based sheets and a second layer applied externally to one of the wood-based sheets.

4. The multi-layer material as in claim 1 , wherein at least one layer of metal material has a progressive reduction in thickness towards its ends, so that the internal wood-based sheet ends in a position upstream with respect to at least the ends of the external wood-based sheets, wherein a shorter length of the at least one metal layer determines a progressive and corresponding variation of overall thickness in the multi-layer material.

5. The multi-layer material as in claim 1 , wherein at least one of the an internal wood-based sheets includes a plastic or acetate material which has a progressive reduction in thickness towards its ends, so that the internal wood-based sheet ends in a position upstream with respect at least to the ends of the external wood-based sheets, or of at least a metal layer adjacent to it, in which a shorter length of the plastic or acetate material determines a progressive and corresponding variation in overall thickness in the multi-layer material.

6. The multi-layer material as in claim 1 , wherein at least one layer of metal material is made of recycled material deriving from tin or aluminum containers.

7. The multi-layer material as in claim 1 , wherein at least one layer of metal material is made of new metal material deriving from industrial processing.

8. The multi-layer material as in claim 1 , comprising at least a covering sheet applied on at least an external surface.

9. An article, including at least one of a furnishing ornament, an accessory for the house, a gadget or a personal accessory, made by a multi-layer material as in claim 1 .

10. A method to make the multi-layer material of claim 1 , comprising the steps of:

disposing a plurality of wood-based sheets;

interposing at least one layer of metal material between two wood-based sheets;

interposing suitable adhesive materials between adjacent wood-based sheets and between the metal layer and the adjacent wood-based sheets;

exerting an adequate pressure on the wood-based sheets and on the layer of metal material thus associated so as to obtain their reciprocal adhesion, wherein the step of disposing a plurality of wood-based sheets provides to dispose at least of said internal wood-based sheets having a progressive reduction in thickness towards its ends, so that the internal wood-based sheet ends in a position upstream with respect to the ends of the adjacent internal wood-based sheets and of the external wood-based sheets, wherein the shorter length of said at least one internal wood-based sheet determines a progressive and corresponding variation in overall thickness in said multi-layer material.

11. The method as in claim 10 , wherein it provides a step of disposing two of said layers of metal material, of which a first layer interposed between at least two wood-based sheets and a second layer interposed in its turn between at least two wood-based sheets.

12. The method as in claim 10 , wherein it provides a step of disposing two of said layers of metal material, of which a first layer interposed between two wood-based sheets and a second layer applied externally to one of said wood-based sheets.

13. The method as in claim 10 , wherein it provides to use at least one layer of metal material having a progressive reduction in thickness towards its ends, so that the internal wood-based sheet ends in a position upstream with respect to the ends of the adjacent internal wood-based sheets and of the external wood-based sheets, wherein the shorter length of said at least one layer of metal material determines a progressive and corresponding variation in overall thickness in said multi-layer material.

14. The method as in claim 10 , wherein it provides to use at least a layer made of plastic or acetate material having a progressive reduction in thickness towards its ends, so that the internal wood-based sheet ends in a position upstream with respect to the ends of the adjacent internal wood-based sheets and the external wood-based sheets, wherein the shorter length of said at least one layer of plastic or acetate material determines a progressive and corresponding variation in overall thickness in said multi-layer material.

15. The method as in claim 10 , wherein at least one layer of metal material is obtained directly by cutting and/or flattening of tin or aluminum containers of suitable sizes.
