CALENDER AND AN ARRANGEMENT FOR FASTENING ROLLS OF A CALENDER

A calender and an arrangement for mounting calender rolls, the calender comprising at least two calender nips (1, 2) formed by at least two stacked rolls (11 - 14). The rolls have bearing housings (3 - 6) by means of which the rolls (11 - 14) are stacked into roll pairs forming the calender nips (1, 2), and means (31, 32) connecting the bearing housings (3, 4 and 4, 5) of the rolls pairs with each other. At least two successive calender nips (1, 2) are arranged so that in the successive nips the mutual distance between the longitudinal axes of the lower rolls (12, 14) is smaller than the corresponding mutual distance between the respective upper rolls (11, 13) of the nips, whereby the disposition of the rolls (11 - 14) forms a V-shaped angle as seen from the end of the calender machinery and thus forms an operating area between the nips for changing the rolls. The rolls are combined into nips advantageously using heatable pull rods inserted through the bearing housings.
