- ⓘ Calculation Notes
- The calculated roll diameters assume a perfectly cylindrical roll with uniform, gap-free winding.

- The product thickness can vary during production within the permitted manufacturing tolerance. - The actual roll diameter may therefore differ from the calculated values.

- Use the ± Tolerance field next to the product thickness to estimate this effect – the result will then show the minimum, nominal and maximum roll diameter. -

- ⓘ Calculation Notes
- The calculated roll diameters assume a perfectly cylindrical roll with uniform, gap-free winding.

- The product thickness can vary during production within the permitted manufacturing tolerance. - The actual roll diameter may therefore differ from the calculated values.

- Use the ± Tolerance field next to the product thickness to estimate this effect – the result will then show the minimum, nominal and maximum roll diameter. +
