Section E. Seam Measurement
E.5 Seam Troubleshooting
After evaluating your seam height, body and cover hooks you might find that your measurements are not within the
specified tolerances. If this is the case you need to make some changes to your seaming operations.
This could include the spacing of the dies, the speed at which they come into the can, or the height of the lift table. You
can refer to the troubleshooting guide below in Table 9 to diagnose what is the cause of your problem and the adjustment
required to fix it.
