Abstract
A three-roll press for a web including a pair of pressing rolls forming a nip and a pressure roll bearing on one of the pressing rolls in which the deflection curve of one of the pressing rolls is matched to that of the other pressing roll by the application of a biasing force to the one pressing roll urging its end toward the pressure roll by an amount which is proportional to the internal moment in the one pressing roll at locations corresponding to the edges of a web in the nip therebetween. A compensating spring is employed to urge the one pressing roll toward the pressure roll. The pressing roll may be a crowned roll or a skewed roll.
