ALPHATWIN Slitter Rewinders

The ALPHATWIN duplex slitter rewinder is a robust centre rewinder with differential rewinding and fully automatic layon roll control for high quality winding. 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.
