<p>A synthetic-grass covering, usable, for example, for making artificial pitches for sports activities, comprises:
- a substrate made of sheet material (10, 12, 20); and
- filiform formations (14), implanted in the aforesaid sheetlike substrate (10, 12, 20) so as to present a looped part (16) that extends up against one of the surfaces of the sheetlike substrate (10, 12, 20) and lateral branches (18) that extend in order to simulate the grassy sward of natural turf from the opposite surface of the sheetlike substrate (10, 12, 20). The substrate made of sheet material (10, 12, 20) comprises a pad (10) with coupled thereto a layer (12) made of heat-meltable material, and the filiform formations (14) are also made of heat-meltable material, with the aforesaid looped parts (16) that extend in an area corresponding to the layer (12) made of heat-meltable material, heat-welded to the aforesaid layer.</p> |
