A bending head for welded wire mesh includes a frame, a bending face to be moved relative to the frame for bending a wire in a welded wire mesh, a counterholder on which the wire can be braced during bending by the bending face, a bending die which, at least in part, has a predefined bending radius, a bending arm on which the bending face is arranged, and an arm drive device with which the bending arm can be adjusted relative to the frame. A support is provided at and/or on which the bending arm is movably mounted. A support drive device, with which the support can be adjusted relative to the frame and which is separate from the arm drive device, is provided.

An edge finishing for a mesh formed by interlacing adjacent wire pickets, each picket formed in a zig-zag manner, the edge finishing comprising two interlinked loops where a first loop is formed from a first picket of the adjacent pickets and a second loop is formed from a second picket of the adjacent pickets, wherein the first loop and the second loop are interlocked together, via first and second loop-ends, at an intersection of the first picket and the second picket.

A chain link fence and a method of manufacturing an improved selvage therefore that provides no exposed ends of wires. The chain link fence of the present invention is manufactured from a plurality of wires coupled in a woven format so as to form loops. The chain link fence includes slats woven through the plurality of loops so as to provide privacy subsequent installation. The chain link fence manufacturing method provides for an improved selvage at the top and bottom thereof wherein the selvage has no exposed ends and as such eliminating the deficiencies of traditional selvages. The method of the present invention includes providing a plurality of bends to the exposed ends of the wire comprising the chain link fence. The plurality of bends culminates in the formation of a novel selvage that has the exposed ends of the wire penetrating into the body of the plurality of slats.

A metal lath having an integral hem structure includes a main body. The main body is formed by enclosing the metal lath so that the main body has a ring-shaped side wall. The side wall defines an accommodating space therein. Two ends of the main body are formed with openings to communicate with the accommodating space, respectively. One of the openings is integrally formed with a hem around an end edge of the opening by bending. The hem is integrally formed with the metal lath, which can reduce production time and cost effectively and can prevent the user from being cut by the metal lath.

A method for manufacturing a three-dimensional lattice truss structure using flexible wires, including: arranging a plurality of out-of-plane wires; forming crossing portions between the plurality of out-of-plane wires; inserting a plurality of in-plane wires in the crossing portions; translating the plurality of in-plane wires in the z-direction; and inserting boundary rods in the y- or x-direction inside the plurality of out-of-plane wire groups.

A method of manufacturing a metal basket contains the steps of preparing materials, initial welding, bending, and finish welding. In a step of preparing materials, multiple first metal bars, multiple second metal bars, and at least two peripheral bars are provided. In a step of initial welding, the multiple first metal bars and the multiple second metal bars are stacked crisscross and are welded together to produce a grid frame which has a base and multiple surrounding grids, and the at least two peripheral bars are welded with the multiple surrounding grids respectively. In a step of bending, the grid frame and the multiple surrounding grids are bent, such that the multiple surrounding grids are bent upwardly and are perpendicular to the base. In a step of finish welding, the at least two peripheral bars are welded together.
