Process for producing synthetic-grass structures and corresponding synthetic-grass structure
First Claim
1. A process for making a synthetic-grass covering, comprising the operation of providing a substrate with a plurality of filiform formations that extend from the substrate to simulate natural-grass cover or sward, said filiform formations being provided with respective proximal ends and distal ends with respect to the substrate, the process comprising the operation of selectively curling only said distal ends by application of a heated flow to said distal ends, bestowing upon said filiform formations a general tree-like conformation.

Abstract
A synthetic-grass flooring may include a substrate with multiple filiform formations extending upwards from the substrate to simulate natural-grass cover or turf. End portions of the filiform formations may be curled to bestow upon the filiform formations a general tree-like conformation. The synthetic-grass flooring may be manufactured as a finished product in a factory. A particulate filling material or infill may be retained on the substrate by the curly ends of the filiform formations.

- 16. A synthetic-grass flooring comprising a substrate with a plurality of filiform formations extending from the substrate for simulating natural turf or sward, said filiform formations being provided with respective basically rectilinear proximal ends and respective distal ends, wherein only said distal ends are substantially curled by application of a heated flow to said distal ends, so that said filiform formations have a general tree-like conformation.

31. A process for making a synthetic-grass covering, comprising the operation of providing a substrate with a plurality of filiform formations that extend from the substrate to simulate natural-grass cover or sward, said filiform formations being provided with respective proximal ends and distal ends with respect to the substrate, the process comprising the operation of selectively curling only the distal end of at least one filiform formation by subjecting at least said distal end to a first temperature greater than a second temperature of at least a portion of said at least one filiform formation.
