Synthetic turf

DETAILED DESCRIPTION It is the purpose of the present invention to provide an improved synthetic grass sports surface that is more resilient, and remains more resilient for a longer period of time, than known synthetic grass surfaces.
It is another purpose of the present invention to provide improved synthetic grass sports surfaces that have improved drainage properties and improved playing properties.
It is yet another purpose of the present invention to provide improved synthetic playing surfaces that are relatively less expensive to manufacture, to install, and particularly to maintain.
It is still another purpose of the present invention to provide synthetic playing surfaces that are less abrasive, easier to mark with lines, and easier to seam.
It is another purpose of the present invention to provide a method for making one embodiment of the present invention having improved drainage properties and a machine for carrying out the method.
In accordance with the present invention, it has been found that an improved synthetic grass surface can be provided by employing relatively widely spaced rows of ribbons.
The wider spacing of the ribbon rows reduces the compaction of the infill that normally occurs with more closely spaced rows, thus extending the life of the surface with respect to resiliency.
Reduced compaction also ensures better drainage.
Wider row spacing should also ensure less wear and abrasion of the ribbons, extending the life of the surface and minimizing the formation of ribbon debris which affects compaction and drainage.
Wider row spacing also allows better cleat penetration and allows the cleats to release easier, thus improving the playing qualities and reducing the risk of injury.
Wider ribbon row spacing can also cause balls on the surface to roll more like they roll on grass, thus improving playing qualities.
Wider ribbon row spacing also makes it easier to loosen the particulate material if it does start to compact, and to clean or replace it.
Wider ribbon row spacing also reduces abrasion to the players when contacting the surface
