Abstract: A hexagonal wire netting, a process for manufacturing such a wire netting and a device for manufacturing a hexagonal wire netting, the device including an assembly of tubes for leading the wires of which every other is twisted into a spiral shape, a spindle assembly and a drum receiving the wire netting, the drum being provided with detent elements. Between each tube leading the spirally twisted wire and the cooperating spindle a straightening guide is located having an inlet opening cooperating with the tube and an outlet opening cooperating with the spindle. The detent elements are arranged on the drum in such a way that the produced wire netting has meshes in which the proportion of the width to the length is less than 0.75.

Abstract: A machine for manufacturing a reinforced net with hexagonal meshes including a plurality of permanently deformable wires, a reinforcing element, and a mechanism for the reciprocal coiling of first wires and second wires in twos. The mechanism has passages for the reinforcing elements, and a feed system for: the first wires, fed in from a plurality of containers mounted on board the machine and provided internally with a predetermined length of the first wires; for part of the second wires, fed in alternately with the first wires, so as to be interwoven therewith in twos in the coiling mechanism; and for the reinforcing elements, fed into the machine. For all the reinforcing elements, a wire receptacle is provided for one of the second wires, the wire receptacle being rotatable around the reinforcing element.

Abstract: A reinforced gabion comprising two adjacent walls with a common edge manufactured using a single sheet of double twisted metal mesh fabric formed from metal wires which have two different diameters respectively corresponding to the two walls. Preferably the metal mesh fabric has a mesh with at least one twisted side formed from at least two metal wires woven together in which each twisted side is aligned in the direction of the common edge between the two walls.

Abstract: Disclosed is a net knitting method. The knitting method comprises: leading multiple first thread materials (3a) and second thread materials (3b) through first rotating members (13a?, 13b?, 13c?) and second rotating members (13a?, 13b?, 13c?) respectively, and cyclically and repeatedly performing the foregoing process through a step of rotating the first rotating members and the second rotating members simultaneously for an odd number of half circles and a step of staggering a first base (11?) and a second base (11?), so as to form an obliquely knitted net. The knitting method can improve the structural strength of the net.

Abstract: A protective wire net including an array of longitudinal wires arranged side by side and each intertwined with at least one respective adjacent longitudinal wire. Each of one or more longitudinal metal cables is also intertwined with at least one adjacent longitudinal wire. One or more transverse wires and/or metal cables may also be provided, arranged in a transverse direction relative to the longitudinal wires and outside intertwining regions defined by portions of adjacent longitudinal wires which are bent around one another, the transverse wires and/or metal cables being intertwined or interlaced with one or more of the longitudinal wires.

Abstract: A protective metal netting comprises a plurality of longitudinal metal wires or cables (10) side by side, each interwoven with at least one adjacent longitudinal wire or cable (10) in an interweave portion (24), in which at least one of the metal wires or cables (20) has an almost rectilinear development, or in any case with loops that are less pronounced than the lower-strength neighbouring cables. A machine for manufacturing interwoven metal nettings comprises a cylindrical drum (50), on the outer surface of which a plurality of pins (52) protruding radially and arranged in axial rows at equal angular intervals is fixed, with an equal pitch in all the rows. Some pins (54) present on the cylindrical drum (50) are fitted out-of-alignment with respect to the above-mentioned pitch.

Abstract: Furred woven wire fabric lathing is provided which incorporates a plurality of wires twisted together forming a wire mesh with a major portion of the wire in a plane with a portion of the mesh comprising furr portions extending out of the plane of the mesh and configured for embedment in plaster upon application of plaster to the wire mesh.

Abstract: Disclosed is a structural material having a lattice configuration. In one embodiment of the invention, the structural material is manufactured by weaving a continuous wire filament on a loom assembly. In an alternative embodiment of the invention, the structural material is formed using substrate sheets that are machined or molded into a desired configuration. The structural material of the invention can be used alone or layered to form a multi-laminate material.

Abstract: Disclosed is a structural material having a wire lattice configuration. The structural material can manufactured by first weaving a continuous wire filament on a loom assembly. Once woven into arrays of parallel wires, the filament is fixed in position and cut into segments. The segments are then placed in a rig. The rig positions the segments at relative angles so as to form a matrix or mesh. In the final step of the manufacturing process, the wires are welded together using, for example, a forge press. Alternatively, the material can be formed by first holding wire segments in a pair of rigs and then sequentially welding the wire segments together. The structural material of the invention can be used alone or layered to form a multilaminate material.

Abstract: Reinforcement for concrete for covering pipes comprises wire netting with line wires extending through at least some of the twists of the netting and with at least some of the line wires crimped in at least some of the meshes of the netting across which they extend.
