Duplex Slitter Rewinders
The ALPHATWIN duplex slitter rewinder is a robust shafted centre rewinder with precise tension and contact control, typically used for flexible packaging and general converting.




The cantilevered winding shafts are rigid during running yet provide for fast unloading and can easily be integrated with a variety of unloading systems. All models can be supplied with automatic knife positioning, fixed or auto setting laser core positioning and powered roll removal to improve productivity. The touch screen operator interface has simple recipe systems for multiple material types and slitting parameters.
