Compound Squeezing
Cross Section Double Seam Defects - Cause & Remedy

Unlike Seam Bumps, Compound Squeezing is a condition where lining compound is forced out through the bottom of the seam between the can body and Cover Hook and usually can be seen all around the can. Compound Squeezing can also be seen through Seam Projector or Scope and will become visible on the inside diameter between the can body and cover. The Seamer will usually have signs of compound building up in the seaming turret area and is mostly due to over tight 2nd Operation Seaming Rolls.
