Seam Length 2nd Op
Second op seam length is a good indicator that you have a correctly formed seam and it’s
also a good indication that your rollers are set to the correct height.
Using calipers check your seam length. This should ideally be about 2.3-2.4mm in length as
shown in the image below. With that said a tight and high pressure seal can still be
achieved if this seam length is even as long as 3.3mm as long as you still have sufficient
actual overlap. As this particular Cannular machine is driven using a manual leaver, it is
possible for the operator to pull too hard on the lever which can also make a longer seam
yet still gives an acceptable finished seam.
