Cleaner slitting

1. Provide sharp slitter knives.
— check the bottoms and tops for nicks.
2. Check that slitters are set correctly.
— ensure sufficient side loading of top slitter knife against bottom knife.

— too deep a penetration into sheet run can cause slitter cracks.
4. Check slitter set-up and location.
5. Inspect slitter bearings for failure.
6. Remove dust by use of suitable vacuum attachments.

1. Never attempt to sharpen slitters on the winder.
