Seamer tooling such as rolls and chucks can become damaged over time. Typically this occurs due to incorrect setup of the seamer.

How to identify and prevent damaged tooling?
The best way to identify and prevent damaged seamer tooling is to ensure the seamer is set correctly and consistently monitor the tooling condition. The easiest way to do this is using the Clearance gauge, which is placed inside the seamer and shows the roll and chuck positions so that they cannot grind against one another.
While setting up the seamer, past damage to the toolings can be identified immediately and the necessary toolings can be replaced preemptively during downtime.
