Reel Winder RWM 2000

The reel winder is used for the production of capacitor rings on a winding reel. Two metalized films are wound up together on a rapidly rotating winding reel. In a subsequent work step the capacitor rings are cut into defined segments—the actual capacitors.

Design Principle

The capacitor films have non-metalized margins on opposite sides. The films are provided on storage reels to be wound onto the winding reel. An air guidance system lets the films float on a cushion of air while being guided laterally. After winding, the two end faces of the capacitor ring are metalized.
