Recent work on a newsprint machine (Journeaux et al., 1992) shows that the actuators might be most effective on the queen roll or one of the rolls immediately above the queen roll, especially if they are unheated, thin-walled rolls. Using a roll with a single nip, such as the king roll or top roll, was not very effective.

Rolling of Metals: Process and Principles (With Diagram)
Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.

Rolling (metalworking) - Wikipedia
Ring rolling is a specialized type of hot rolling that increases the diameter of a ring. The starting material is a thick-walled ring. This workpiece is placed between two rolls, an inner idler roll and a driven roll, which presses the ring from the outside. As the rolling occurs the wall thickness decreases as the diameter increases.
