Abstract
Process for exchanging an intermediate roll in a calender and a calender. The calender has more than three rolls arranged to form a pressing plane obliquely oriented at a predetermined angle to a vertical, the intermediate roll to be exchanged being positioned immediately above a neighboring roll. The process includes lowering the neighboring roll at least a distance h defined by the equation:h=(r1+r2)(1−cos &agr;), in which r1 is a radius of the intermediate roll, r2 is a radius of the neighboring roll, and &agr; is the predetermined angle, and substantially horizontally removing the intermediate roll to be exchanged.
