A multi-web type textile article (11 ), in particular for covering wide surface areas, made of a plurality of webs or sheets (12) of non-woven of a given material (M), for example polypropylene, joined together, wherein the various sheets (12) are produced, using a "spunbond" type process, so that they have a density (D) of material (M) per unit of surface area which is greater at the edges (12a) than in the centre (12b) of each sheet, and wherein furthermore the sheets (12) are joined together to form the multi-web article along the respective edges (12a) possessing this greater density of material, so that the article (11 ) is characterized by improved resistance and tenacity both in the area of the junctions (11a) between the various sheets (12) and along the respective external lateral edges (11 ') that are not joined. |
