Since the insulating paper was originally only wrapped around the capacitor core, the insulating paper and film were combined and wrapped around the capacitor core. The original cutting circular blade, along with the linear motion of the rodless cylinder, naturally rolls and cuts the insulation paper transversely. At present, a film is added.

The film may even be arched in the middle of cutting, or the tail paper film may be damaged, and the film is not completely tightened by the tension shaft. The paper film has a higher failure rate, and even with a sharp straight blade, the cutting effect is still poor. Insulating paper is brittle and easy to cut, but the film is thick and tough enough, so cutting reliability is not high. As a result, the paper film is often worn, which wastes operating time and affects production efficiency.
