    • 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.
    • 可以用作加强框架的无纺布网格,包括通过粘合剂粘结而相互连接的纵向丝线和交叉线的叠合线,并且限定可使所述网状物嵌入被加强材料内的孔, 进入所述电网结构的电线(1a,1b)(2)由复丝化学电线组成,其机械特性不受被加固结构的性质的阻碍; 在所述网格中,交叉线(2)被囚禁在两组纵向导线(1a,1b)之间,它们之间叠置着它们; 用于将电线彼此连接的粘合剂沿着其整个长度包围所述电线,并且在两个连续的交叉线(2)之间的区域(4)中连接成对的纵向电线(1a,1b),从而将所述电线 相互之间。 本发明的特征在于,至少交叉搭接由无扭曲的复丝线组成,由此其长丝设置成平行的平坦位置,形成相对于其厚度的宽带。
