  • Groundcovering element, method for its manufacture and method for the manufacture of a mould to be applied with the manufacturing method
    Patent number: 5615971
    Abstract: The invention relates to a groundcovering element, consisting of a plurality of components (1) with links (2,3) in between, a method for the manufacture thereof and a method for the manufacture of a mold (24, 25, 26, 27, 29, 30). According to the invention it is provided that the links between the components are deformable, possibly flexible and allow for a distance between adjacent components, resulting in a groundcovering element that is easy to lay, offers better possibilities of adjustment to various desired surfaces to be covered and is considerably more suitable for a more or less undulating terrain. In a method of manufacture, one steel mold part (34) cooperates with many rubber ones (31), so that with little investment a high production rate is obtained.
