US Patent 9381661 Corrosion protected anvil and knife cutting assembly

A corrosion protected knife and anvil system is disclosed. A source of lubricating fluid is provided to a lubricating fluid distribution mechanism, coupled to both a knife blade and a salt bridge and an associated sacrificial anode. The sacrificial anode is consumed in order to protect corrosion on a rotating knife blade, which intermittently contacts both an associated anvil in order to cut material used in making disposable products, and the source of lubricating fluid. A knife holder holds a knife which is corrosion protected by an impressed current anode.
