Abstract
A double seamer; included a chuck and a lifter plate vertically aligned with each other. Seaming rolls are set near the chuck. When a can body wall with a lid is clamped between said chuck and lifter plate, the spring pressure of a resilient member supporting the lifter plate is measured and if the measured value is less than a predetermined value, the can body wall is judged to have been crushed. The seamer is included with a ring cam plate having a high spot and a low spot. The high spot is provided with a load bearing member and a load cell installed underneath the load bearing member such that the spring pressure is measured when a cam roll set at the lower end of a lifter plate support member is in contact with the load bearing member.
