CALENDER

摘要

The calender contains two permanently or provisionally separate stacks (A, B) of three rolls. In each stack there is an upper roll (1; 4) and a lower roll (3; 6) upper roll (4), and a centre roll (2; 5) in nip contact with the upper roll and the lower roll. Said upper and lower rolls are mounted in a fixed position on the frame (R) of the calender in such a manner that their shells can be moved in the direction of the stack of rolls with respect to the supports (9) of the rolls. The rolls can in this way be detached from the nip contact with the centre roll. The upper and the lower roll (1, 3, 4, 6) in both stacks of rolls are soft-faced rolls and the centre rolls (2, 5) are hard thermo rolls.
