Abstract

A sheet for manufacturing articles, particularly frames for glasses and the like, including at least one technical layer made of a thermoplastic material interposed between a first aesthetic layer and a second aesthetic layer, both made of a material such as fabric. A method for producing a sheet for manufacturing articles includes the steps of providing at least one technical layer made of a material such as thermoplastic polymers and at least two aesthetic layers made of a material such as fabric and associating the technical layer with the aesthetic layers. The layers are mutually compressed and then heated to obtain the sheet.

First claim

The invention claimed is:

1. A sheet for manufacturing articles, particularly frames for glasses, comprising at least one technical layer made of a thermoplastic material that is interposed between a first aesthetic layer and a second aesthetic layer, both made of a material such as fabric, wherein said at least one technical layer is adapted to receive a metallic core interposed between said technical layer and one of said first and second aesthetic layers.

2. The sheet for manufacturing articles, according to claim 1 , wherein the material of said technical layer is a polyolefin.

3. The sheet for manufacturing articles, according to claim 1 , wherein the material of said at least one technical layer is polypropylene.

4. The sheet for manufacturing articles, according to claim 1 , wherein the material of at least one of said first and second aesthetic layers is denim fabric.

5. The sheet for manufacturing articles, according to claim 1 , comprising a plurality of said aesthetic layers alternated with said technical layers.

6. The sheet for manufacturing articles, according to claim 1 , comprising at least two technical layers that are interposed between three aesthetic layers alternated with said technical layers.

7. A frame for eyeglasses comprising a front adapted to accommodate a pair of lenses and two lateral temples, wherein said front and said lateral temples are obtained from one or more sheets according to claim 1 .

8. A method for producing a sheet for manufacturing articles, particularly frames for eyeglasses, comprising the steps of:
having at least one technical layer made of a material such as thermoplastic polymers and at least two aesthetic layers made of a material such as fabric;
associating said at least one technical layer with said at least two aesthetic layers;
mutually compressing said at least one technical layer and said at least two aesthetic layers;
heating said at least one technical layer and said at least two aesthetic layers mutually associated to obtain said sheet; and
interposing a metallic core between said at least one technical layer and one of said at least two aesthetic layers.

9. The method for producing a sheet, according to claim 8 , wherein said step of mutually compressing said at least one technical layer and said at least two aesthetic layers and said step of heating said at least one technical layer and said at least two mutually associated aesthetic layers are simultaneous.

10. The method for producing a sheet, according to claim 8 , further comprising one or more steps of surface treatments of said sheet.
