3. Grille settings and controls

The aim is to obtain a sheet with a regular and consistent thickness profile and uniform tension, enabling a cylindrical coil with a consistent diameter across its entire width to be produced during winding.

3.1 Calendering parameters

The passage of material between the cylinders exerts a linear load on them, distributed over the width l of the sheet at the gap between two successive cylinders (figure 14 ), and a resistive torque due to the shear stress exerted by the material on the surface of the cylinders. We will see in section
