Calendering parameters
The flow of material between the rolls exerts a linear load along the generatrices and a resistive torque due to the splitting of the material at the roll surface. We'll see in 4 that this flow force depends on roll radius R, sheet width W, calendering speed U, calender roll gap 2 h 0...
