A brush strip is formed from a metal channel member (1) which receives the roots of plastics filaments (2) and is pinched to clamp them. The strip is then formed into a Flemish coil with the filaments (2) upstanding to provide an artificial turf surface. Underneath, metal bars (5) may be welded to the channel member (1) to rigidify the structure and complete the mat. They can also assist location at different angular positions in a surround (7). A hole (4) at the centre of the coil can be plugged with an insert which can carry a flexible tee peg or receive ordinary pegs. Alternatively, the hole can serve as access for practice balls to be lifted or projected up on to the mat. A circular mat with upstanding filaments can be provided by other brush constructions, and the filaments may differ in length and/or stiffness in different areas. |
