  • Patent number: 11230799
    Abstract: An artificial turf mat includes a backing and a number of protruding artificial grass blades divided into rows and connected thereto. The mutual distance between successive blades in a row is substantially equal to the distance between adjacent rows and amounts to at least 10 mm. Such an artificial turf mat can be used to form artificial turf fields, for example, on which sports, and in particular ball sports, are played.

  • Patent number: 10227716
    Abstract: An artificial turf mat includes a backing and a plurality of protruding artificial grass blades divided into rows and connected to the backing. The mutual distance between successive blades in a row is substantially equal to the distance between adjacent rows and is at least 10 mm. The backing and the blades may be formed and mutually connected by weaving. A method for forming an artificial turf mat includes supplying a backing material, supplying an artificial turf material, forming a backing from the backing material, and connecting blades of the artificial turf material divided into rows to the backing. The blades may be connected to the backing such that their mutual spacing in a row is substantially equal to the mutual distance between adjacent rows and is at least 10 mm.

  • Patent number: 10011964
    Abstract: Method for forming a ground-covering layer (1), comprising the steps of providing a sheet (2); forming a number of substantially parallel folds (3) in the sheet; and urging toward each other and connecting to each other adjacent folds at different locations wherein the connections of each fold to an adjacent fold on the one side are offset relative to the connections to an adjacent fold on the other side. Ground-covering layer (1), comprising a sheet (2) with a number of substantially parallel folds (3), which folds are connected at different locations to adjacent folds, wherein the connections of each fold to an adjacent fold on the one side are offset relative to the connections to an adjacent fold on the other side.

  • Patent number: 9388536
    Abstract: The invention relates to a method for forming an artificial grass layer on a substrate, comprising the steps of supplying a pack of flat and deformable artificial grass strips, in which the strips are arranged with their flat faces side-by-side and are connected to each other at mutually offset locations, placing the pack of artificial grass strips on or partially in the substrate, pulling apart the artificial grass strips, thus forming a grid, and at least partially filling at least some of the openings in the grid with a stabilizing material. The invention further relates to a method for forming such a pack of flat and deformable artificial grass strips.

  • Patent number: 8491974
    Abstract: The invention relates to an artificial turf, comprising a backing and a number of artificial grass blades connected to the backing and extending transversely of the surface thereof, which artificial grass blades have an irregular, in particular a locally narrowed, cross-section. Owing to this locally narrowed cross-section in the vicinity of the free end thereof, these artificial grass blades greatly resemble natural blades of grass and also display similar behavior. The invention also relates to a method for forming such an artificial turf and to a device with which this method can be performed. The narrowed cross-section can herein be formed by stretching the artificial grass blades, wherein the artificial grass blades can be plasticized before, during and/or after the stretching, for instance by local heating thereof.
