The bottom feed slitting rewinder receives paper rolls from the paper-making machine and positions them on the unwinding station. Its integrated brake system maintains precise web tension while enabling instant stopping to minimize paper waste during web breaks. The machine precisely slits the paper width through guided rollers and cutting mechanisms, then rewinds the material to specified tightness and diameter tolerances.
