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. 40% (min.) of the total seam length.
- The Calculator given above is for reference only. BMT™ does not guarantee the accuracy of the results and is not responsible for any errors/omissions therein.
