The series of Semi-automatic crimped wire mesh machine weave crimped wire net of steel, iron, lead and stainless steel wire with big diameter. The net is weaved by the machine after the thick wire is formed to crimp by the rolling machine. Breadth of the net is 0.9-2.5m and the diameter of the wire is 2.0-8.0mm. The size of the mesh is 2×2mm-80×80mm. The structure of the machine is compactness and rational. It performs satisfactorily and runs smoothly.
