CALENDER AND AN ARRANGEMENT FOR FASTENING ROLLS OF A CALENDER

摘要

A calender and an arrangement for mounting calender rolls, the calendercomprising at least two calender nips (1,2) formed by at least two stacked rolls (11 - 14). The rolls have bearinghousings (3 - 6) by means of which the rolls (11 - 14) arestacked into roll pairs forming the calender nips (1, 2), and means (31, 32)connecting the bearing housings (3, 4 and 4, 5) of therolls pairs with each other. At least two successive calender nips (1, 2) arearranged so that in the successive nips the mutual distancebetween the longitudinal axes of the lower rolls (12, 14) is smaller than thecorresponding mutual distance between the respectiveupper 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 thecalender machinery and thus forms an operating area between the nips forchanging the rolls. The rolls are combined into nipsadvantageously using heatable pull rods inserted through the bearing housings.
