FIELD: means for securing of slopes or inclines, particularly ground consolidation netting. ^ SUBSTANCE: plastic netting comprises oriented strips 6, 9, which form triangular cells so that strips are connected with each other in connection points 11. Six strips 6, 9 converge at each connection point 11. Plastic source material has orifices defining hexagon grid array so that opposite orifices of each hexagon are aligned in processing direction. Source material is preliminarily expanded in processing direction and in transversal direction. Ready ground consolidation netting 10 has hexagon centers, which create connection points 11. Connection point 11 centers are slightly biaxially oriented, but edge of each strip 6, 9 extends about corresponding connection point 11 edge and passes into next strip 6, 9 edge at connection point 11 edges. During the second expanding operation retaining force may be applied in the first direction and released before provision of material relaxing in the second expanding direction. ^ EFFECT: increased efficiency, possibility to create netting of source material having through orifices and weakened zones. ^ 44 cl, 17 dwg, 3 ex |
