+ ⓘ 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. +
