US Patent 7249913 Roll up artificial turf

A filled artificial turf includes a plurality of filled artificial turf sections which can be disconnected, rolled up and stored and then later unrolled and reconnected, thereby to enable a facility to accommodate a wide variety of sporting and non-sporting events, with no adverse effects on the playability of the turf. Each of the sections includes a backing, fibers secured to the backing, and a particulate fill with the fibers being of sufficient density and texture so as to substantially hold the particulate fill to the backing during rolling and unrolling. The sections also include hook and loop fasteners along the edges thereof, to facilitate simple and cost-effective connection and disconnection of the sections.
