The air cools the roll and causes a local decrease in roll diameter and an increase in sheet thickness. 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.
