Abstract

Keksinnön kohteena on sovitelma kalanterin telajärjestykseksi, joka sovitelma käsittää taipumakompensoidut ylä- (1) ja alatelan (7), jotka on sovitettu oleellisesti päällekkäin välimatkan päähän toisistaan, ylä-(1) ja alatelan (7) väliin sovitetun välitelaston, joka käsittää ainakin yhden välitelan (2-6), ainakin kaksi päällekkäisten telojen (1-7) muodostamaa kalanterinippiä, joiden läpi kalanteroitava raina on sovitettu kulkemaan, ja kevennyslaitteet välitelaston telojen (2-6) kannattamiseksi. Lähinnä ylätelaa (1) oleva välitelaston (2-6) pehmeäpintainen välitela on kuitupinnoitteinen tela, joka on sovitettu tasaamaan telojen (1-7) erisuurista taipumista nippeihin aiheutuvia kuormituseroja.The invention relates to an arrangement for a calender roll arrangement, which arrangement comprises deflection-compensated upper (1) and lower rolls (7), which are arranged substantially one above the other at a distance from each other, an intermediate roll set arranged between the upper (1) and lower rolls (7), which comprises at least one intermediate roll (2-6), at least two calender nips formed by the overlapping rolls (1-7), through which the web to be calendered is arranged to pass, and lightening devices for supporting the rolls (2-6) of the intermediate roll set. The soft-surfaced intermediate roll of the intermediate roll set (2-6) closest to the upper roll (1) is a fiber-coated roll, which is arranged to equalize the load differences caused by the different deflections of the rolls (1-7) on the nips.
