Abstract
Crimped seals that are formed in overlapping portions of a packaging material are tested for quality. Initially, the packaging material is installed on first and second clamps. A portion of the packaging material is then extended between first and second crimpers. The first and second crimpers are moved into engagement with the portion of the packaging material to form a crimped seal. During this engagement, the amount of force that is exerted on the portion of the packaging material by the first and second crimpers to form the crimped seal is measured. Then, the first and second clamps are moved to pull apart the crimped seal. The amount of force that is exerted by the first and second clamps to pull apart the crimped seal is also measured. An apparatus for testing the quality of such crimped seals is also provided.
