And a cutting step of cutting the vertical wires 6 such that the wire meshes 5 continuously manufactured by the vertical wires 6 wound on the bobbin have a predetermined width, and the cut wire mesh 5 is "U". A bending step of bending to correspond to the shape of the male drainage path, a socket part forming step of bending the horizontal line 7 to the shape of the socket part of the drainage path of the socket-shaped part 8 of the bent wire mesh 5, and the bending Horizontal lines By a bent portion in the socket portion a vertical pipe (9) to (7a) in the socket part welding step of spot welding to produce one of the completed wire mesh (5).

Meanwhile, in the conventional wire mesh manufacturing process as described above, the welding step, the cutting step, and the bending step are automated by a continuous series of devices, while the carrying ring portion after the bending of the wire mesh is completed as shown in FIG. 2. After attaching a large number by hand.

As described above, when attaching the carrying ring by hand, the worker complains of pain, the carrying ring is irregular, and there is a problem that productivity is reduced.

An object of the present invention for solving the problems as described above, by attaching the hook of the wire mesh for transporting the drainage channel by automating the entire process, including the molding operation, to reduce labor and to produce a uniform wire mesh It is possible to reduce the defective rate, and to provide a wire mesh manufacturing apparatus that improves productivity by shortening the working time, the wire mesh to the concrete drainage by performing the ring forming step and again welding step in the welding step and the next process Fully automated manufacturing process of the transport ring portion of the transport ring forming apparatus and carrying ring ring welding device for carrying out the carrying ring forming step and the carrying ring welding step comprises a transport ring forming device equipped with welding means do.
