The cantilevered winding shafts are rigid during running yet provide for fast unloading and can easily be integrated with a variety of unloading systems. The ALPHALAB  can be supplied with twin differential rewinding shafts for sensitive films and foams or with single winding shaft suited to labelstock, papers and rotary die cutting applications. The touch screen operator interface has simple recipe systems for multiple material types and slitting parameters.
