Abstract
A process for field preparation of a fibrous turf on a surface by steps including: (a) inserting fibers into a backing to obtain a backing with inserted fibers; (b) laying a receiving matrix on the surface; (c) bringing a portion of the backing with inserted fibers into connection with the receiving matrix so as to immerse the inserted fibers in the matrix; and (d) maintaining said portion of the backing stationary for a sufficient period of time so that the fibers will stay in the matrix upon removing the backing from the fibers. Preferably the receiving matrix is a thermoplastic substance comprising sulfur, especially plasticized sulfur.
Claims8
A process for continuous field preparation of a fibrous turf on the ground using a wheeled vehicle which is moved forward at a ground speed and which has a continuous rotatable belt operably connected to the vehicle, which process comprises:
- a. inserting fibers into the continuous rotatable belt, the belt being adapted to have fibers inserted therein, to obtain a belt with inserted fibers;
- b. laying a receiving matrix on the ground;
- c. bringing a portion of the belt with inserted fibers into connection with the receiving matrix as the vehicle moves forward so as to immerse the inserted fibers in the matrix;
- d. operating the belt member of the moving vehicle similar to a tank tread;
- and
- e. maintaining said portion of the belt in zero relative velocity to the ground, by rotating the belt by drive wheels at a speed equal to the ground speed of said vehicle, for a sufficient period of time so that the fibers will stay in the matrix upon removing the backing from the fibers.
