NOTES:

  • Operating Limit : Equipment used under normal circumstances, combined with cans and ends (lids) manufactured to industry standards, should give seams with measurements within these limits.
  • Measurements are for 3 piece standard sanitary cans, used as a reference for the canning industry.
  • The Can and End (Lid) dimensions must be as per standards to achieve the correct final Seam profile.
  • Seam Length greatly depends on the groove of the second operation roller and is directly proportional to the overlap, which should be approx. 60% (min.) of the total seam length.
  • Double Seam tightness is ascertained by the wrinkle rating. more info 90 (0.075) min.
