Eroded (damaged) seaming roll

Damaged seaming rolls are very common and in many cases, overlooked and missed by operators since the issues (particularly in 1st operation rolls) are difficult to spot and identify.

In most cases, the damage to the rolls was caused due to incorrect seamer setup.

Damaged rolls will cause all sorts of problems, including deformed seams, open seams. Defects in the roll lip for first operation can even cause droops, low overlap (high seam length) or false seams.

How to ensure Rolls are undamaged and are safe to use?

There are two types of tools used to ensure rolls are safe to use:

• Clearance gauge – basically a visual tool that you place into the seamer to inspect the rolls against the chuck to verify their position. This tool allows the operator to see major defects that are typical with incorrect seamer setup. The benefit of this technique is that it does not require taking out the roll.
• Profile scanners – computerized roll profile scanners work by scanning the profile of the roll and comparing it to a diagram standard. These tools are the most accurate way to detect roll problems, but require the operator to take the rolls out of the seamer in order to scan them.
