Abstract:
A method for forming a synthetic turf-playing surface (10) upon a ground surface, comprising the steps of:providing a carpet-like cover having a base sheet (14) with closely spaced apart, upright, grass-like blades (12) made of narrow, elongated strips of plastic material, with the strips having lower end portions secured to the base sheet (14) and free upper end portions (11) spaced above the base sheet (14); laying a resilient cushion pad (18) upon a support surface and laying the cover upon the pad; blasting sand-like particles (20) against the upper portions of the blades (11) at sufficient pressure and for sufficient time to shred the blade upper end portions (11) into fine slivers (23) which remain joined to their respective blades and which tangle together to form a dense, intertwined matted exposed grass-like upper surface (24) upon the carpet, and characterized by resiliently supporting the upright blades with the cushion pad (18) during the blasting against being crushed or permanently compressed against the base sheet during the blasting.
