<p>A non-woven mesh which can be used as a reinforcing frame, comprising superposed laps of longitudinal wires and cross-wires joined to each other by adhesive bonding and which define apertures enabling said mesh to be embedded inside the material which is to be reinforced, wherein wires (1a, 1b) (2) entering into the construction of said grid are composed of multifilament chemical wires whose mechanical characteristics are not impeded by the nature of the structure to be reinforced; in said mesh, the cross-wires(2) are imprisoned between two series of longitudinal wires (1a, 1b) which are superposed therebetween; the adhesive used to join the wires to each other surrounds said wires along the entire length thereof and links the pairs of longitudinal wires (1a, 1b) in areas (4) contained between two consecutive cross-wires (2), firmly maintaining said wires in relation to each other. The invention is characterized in that at least the cross-lap is composed of torsion-free multifilament wires, whereby the filaments thereof are disposed in a parallel, flat position forming a wide ribbon in relation to the thickness thereof.</p> |
