The first filaments are defined by laminar structures exhibiting flat surfaces substantially lying in the lie plane, and a plurality of substantially rectangular windows are present at the first and second lie plane.

Abstract: A sheet-like element for reinforcing, separating and draining large structures such as road embankments. The element includes a sheet-like body which has a lattice like configuration with main wires and transverse wires stretched respectively along two mutually substantially perpendicular directions and that intersect in nodes. The main extend in the extrusion direction of the blank. The main wires have an upper rim and a pair of substantially vertical lateral walls extending downwardly from the upper rim at opposite ends of said upper rim. The main wires have a lower rim in regions remote from the nodes. The main wires have a lower portion in regions at the nodes which converge with the transverse wires.

Anchoring portions extend from the prevalent development plane of the net structure, which anchoring portions, in use condition, are destined to face towards a terrain surface. The elements comprise at least an anti-slip element situated on an opposite side to the anchoring portion with respect to the development plane of the net structure.

Also described are a use of the product and a method for manufacture thereof.

Abstract: A sheet-like element, such as a net, particularly for geotechnical applications, comprising a sheet-like body formed by superimposing at least two sets of filaments in order to provide a lattice-like structure, the sheet-like body being provided by a first polymer, which defines the lattice-like structure, and a second polymer, which is coextruded together with the first polymer and affects at least regions of at least one face of the sheet-like body, the first polymer having physical and mechanical characteristics of compressive and tensile strength, while the second polymer has a high friction coefficient.

Abstract: A net for delimiting working areas comprises a laminar structure of plastic material presenting a first prevailing dimension and a second dimension transversal to the first dimension, said laminar structure presenting at least a plurality of lightening perforations defining a plurality of substantially planar longitudinal bands that extend along the first dimension and a plurality of planar transversal bands that extend along the second dimension. The first and second bands intersect at respective nodes to form a plurality of meshes. The first dimension exhibits mechanical tensile strength properties that are similar to mechanical tensile strength properties of the second dimension and the laminar structure exhibits a weight per square metre comprised between 20 g/m2 and 100 g/m2. The laminar structure thus obtained is advantageously realised with a double-stretching stage performed first along the first dimension and then along the second dimension.

Abstract: A process for production of a three-planar net has been conceived, which net consists of a plurality of thread-like elements (2a) of a first series (2) parallel to each other and secured to a plurality of thread-like elements (3a) of a second series (3) parallel to each other and transverse to the elements of the first series (2); the elements (3a) of the second series (3) are in turn secured to elements (4a) of a third series (4) parallel to each other and transverse to the elements of the two first series. The production process contemplates a step of stretching the three-planar-net article thus obtained (10) for modifying the weight features per unit of measurement of the net itself according to the specific requirements.
