You can roll the calculation of paper or film.

We are using the following formula.

D: winding outer diameter
d: Core outside diameter
The T: winding thickness
t: film thickness
d1: core outer periphery
D1: winding outer periphery
The T: winding thickness

t × M = ((D1 + d1) / 2) × T
       = ((D × π + d × π) / 2) × (D - d) / 2
       = Π / 4 × (D ^ 2 - d ^ 2)



1, the "winding outer diameter, core outer diameter, film thickness, film length"
   "Winding outer periphery, the core outer periphery, winding thickness, film length, film thickness" of
   Choose whether to calculate either.
2, enter all the data of the other items that you want to find.
3, when the user presses the button calculation results will be displayed.
