    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, thinwalled rolls. Using a roll with a single nip, such as the king roll or top roll, was not very effective. As the caliper control is in the early nips, the actuator is more ...
