The precise and powerful roller pressure unit generates linear loads from 5 to 90 N/mm (VIVA rolls) or 5 to 120 N/mm (P-rolls). Compared to conventional three-roll mills this range is signifi-cant wider for both low and high roller pressure. Products, previously produced in gap operation can be processed in low roller pressure range (5 to 25 N/mm).
