Damaged seamer tooling

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

It is common for the 1st operation roll or 2nd operation roll to be set too low or too tight against the chuck and grind the profile or even cause cracks.

How to spot damaged seamer tooling (using the Clearance Gauge)

Chuck damaged by a tight 2nd operation roll (note the wear at the bottom right)


Damage to the chuck due to incorrect roll height setting (note the broken corner at the top left):

Damage to the first operation roll, likely due to tight first operation (note the abnormal radius at the bottom right side of the roll):

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.
