The working theory of RS-328B resistance-wire winding machine for the manufacturing of compact spiral coils is to reel the coil to the payoff with a brake gear, guide the resistance wire to precision spinning by the wire carrier, and twine the wire around the core axle by an adjustable speed rotary device. The inside diameter of the coil is decided by the external diameter of the core axle, which can be altered free and controlled by coder and PLC touch screen. The resistance value needed could be set and amended on the touch screen to achieve resistance control. As long as the wire comes to the preset resistance, it would be cut through the displacement or the electromagnet. The PLC can record and control the quantities of the spiral coils, and the adjust control the rotational speed of the core axle.
