These wire nets generally make wire ropes made of fiber or metal crosswise to each other to maintain constant strength. In order to enhance the organic bonding force between wire ropes, wire ropes and adjacent wire ropes are twisted together .

For example, in Korean Patent No. 10-1318918 entitled " Protective Wire Nets & Protective Structures ", longitudinal wires include mutually adjacent longitudinal wires and twisted portions twisted together. However, the wire connected to such a twisted wire is not robust, and most of the time it takes a long time because of manual operation.

In addition, Korean Patent No. 10-1138666 entitled " Wire rope netting " has wire rope clips for constituting a mesh body. A plurality of wire ropes are placed horizontally parallel to each other. And passes through the strands.

However, the wire rope clip is formed by cutting a stainless steel wire piece into a square shape or a rectangular shape and then bending both sides so that both sides are opposed to each other. In the wire rope clip, a wire rope is passed through one strand or two strands, The manufacture of rope clips is complex. In addition, since the wire rope must be passed through the wire rope clip one by one or two by two, the manufacturing process is complicated and takes a long time.

In order to solve the above-mentioned problems, the present invention provides a wire net manufacturing apparatus capable of producing a wire rope formed by a corrugated wire and a crest of a wire rope adjacent to the wire rope by press- do.

Another object of the present invention is to provide a wire net manufacturing apparatus in which the wire rope can be easily inserted into a stationary clip, and the stationary clip can be easily and quickly fastened by press working.
