Abstract (en)
The mesh has a set of helically curved wires (11 - 16) curved over or fitted with a set of loops (11a - 16a) at ends of the curved wires. The curved wires have an angle of twist (alpha) and a length (L) between two curves, where two adjacent wires are flexibly connected to each other in an area of the curves. A set of longitudinal reinforcement elements (31 - 35) is guided through a coupling area (A) of the helical wires and causes a set of rhomboidal meshes (17) to be divided into triangular meshes (17a, 17b).
