Foil Winding Machine

The Foil Winding Machine is specialized equipment for winding transformers. The foil material passes through the unwinding device into the guide rollers, then through the crimping/deburring unit and the shearing unit, before reaching the winding mandrel.The interlayer insulation feeder is installed behind the main winding shaft. The insulation is wound onto the mandrel after being cut by the shearing blade.
