Bottom Feed Slitting Rewinder

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.
