A pre-stretched or not polyethylene film produced by the extrusion method and adequately combined plastic materials. Cut out in threads, the produced film is knit by a knitting machine to form a meshed web (fig.7). The knitting machine of the figure7 is provided with two additional automations 9 serving for the incorporation of the retro reflectiing tapes on the mesh in the machine direction (MD) (14,13,12) and the transversal direction (TD) (15,6,17,18,15,16,20). This production process allows the incorporation of plural retro reflecting tapes to the knit mesh in a parallel or vertical arrangement and in respect to the mesh flow direction (4,7). The resulting final product is a meshed web such as fence or netting knit with synthetic threads (6,19) in a selectable knitting manner; furthermore, same product may be fabricated in a controllable length and width and bear a plurality of incorporated retro reflecting tapes (4,7). |
