| 摘要 |
This invention relates to a sheet-shaped welded netting of metal at least comprising mesh-forming wires extending longitudinally of the sheet and/or mesh-forming wires extending transversely of the sheet as well as several deformed stretching wires extending longitudinally of the sheet which can stretch under tensile stress and which may or may not have the function of mesh-forming wires extending longitudinally of the sheet, the deformations in the stretching wires substantially lying in the plane of the netting and the stretching wires displaying a regular arrangement of identical patterns longitudinally of the sheet, whereby the deformation of the stretching wires is such that the ratio of the maximum dimension (B) of a mesh longitudinally of the sheet to the distance (A) between two consecutive maxima in a deformed stretching wire is at least about three, that the maxima of two adjacent stretching wires of the welded netting may or may not have the same position with respect to the longitudinal direction of the netting and that the arrangement of identical patterns of each of the stretching wires is randomly positioned with respect to the arrangement of the meshes in the welded netting.
