Preventive maintenance programs plus qualified operators go a long way toward extending the lives of slitters and rewinders.

Side-load
Correct side-loading of the upper blade accomplishes two things: the blade will shift away from the anvil blade prior to disengaging, and the upper blade is driven by the anvil.

Over-speed
Over-speed is used on tangent slitting only where the material contact to the blade is minimal. If you can be turning faster than the web, then the results of the cut will be much cleaner.
