Jiangyin spring winding machine equipment supplier manufacturer
The machine is equipped by four pieces of wire coiling bars, which can
rotate in synchrony by to-and-fro way for layers of wire-spiral coiling, to increase the length of wire spiral
and to reduce the time of wire spiral changing during twisting to increase mesh-twisting efficiency. This
machine, after changing the preset exchange gears, can meet the wire-spiral-coiling function for different
diameter of wires
