Complex-patterned wire net and method for manufacturing the same

Abstract

Disclosed are a complex-patterned wire net, which is mainly used for fences, and a method for manufacturing the same. The complex-patterned wire net (A) includes first net holes ( 100 ) in an even number obtained in zigzag by repeatedly forming twisting parts ( 110, 120, 130 ) by stretching longitudinal wires from twisting parts ( 110, 120, 130 ), obtained by twisting two strands of wires, to the right and left and twisting the longitudinal wires with the neighboring longitudinal wires at an interval of extensions ( 140, 150, 160 ), such that upper and lower portions of the longitudinal wires divided by divisional transversal wires ( 170, 180 ) supplied during twisting are twisted in the opposite directions, and second net holes ( 200 ) in an even number obtained by repeatedly forming twisting parts ( 210 ) by repeatedly forming twisting parts ( 210 ) by stretching longitudinal wires from the lowermost twisting parts ( 130 ) of the first net holes ( 100 ) to the right and left and twisting the longitudinal wires with the neighboring longitudinal wires at an interval of extensions ( 160 ), such that portions of the longitudinal wires divided by each of plural compartmental transversal wires ( 220 ) are twisted in the opposite directions.
