Stepped calander

A calender is disclosed comprising at least two calender nips formed by at least two stacked rolls ( 8, 9; 14, 15 ) so disposed mutually in regard to each other that in the successive pairs of rolls the distance between the center axes of the lower rolls ( 8, 14 ) of the roll pairs is smaller than t...

Zusammenfassung:	A calender is disclosed comprising at least two calender nips formed by at least two stacked rolls ( 8, 9; 14, 15 ) so disposed mutually in regard to each other that in the successive pairs of rolls the distance between the center axes of the lower rolls ( 8, 14 ) of the roll pairs is smaller than the distance between the center axes of the respective upper rolls ( 9, 15 ), whereby the rolls ( 8, 9; 14, 15 ) as seen from their ends are staggered in a Vangled configuration so as to leave space therebetween for changing the rolls. The invention provides a very compact calender construction by way of having the pairs of rolls ( 8, 9; 14, 15 ) staggered in regard to the vertical plane so as to locate the rolls at different height levels.
