Keksinnön kohteena on pääpaten+in n:o 58801 (pat.hak. n:o 761764) patenttivaatimuksen 1-14 mukaisessa kalanterissa käytettävä taipumakompensoitu, sopivimmin pehmeäpintainen tela (10), jonka taipumakompensointia varten on telan (10) kiinteän akselin (14) ja pyörivän vaipan (12) väliin sovitettu ainakin kaksi, keskenään riippumattomasti säädettävissä olevaa kompensoi nti vyöhykettä.The invention relates to a deflection-compensated, preferably soft-surface roll (10) for use in a calender according to claims 1-14 of the main patent + in No. 58801 (Pat. No. 761764), the deflection compensation of which comprises a fixed shaft (14) of the roll (10) and at least two independently adjustable compensation zones arranged between the rotating jacket (12).

Esillä olevan hakemuksen pääpatentissa n:o 58801 on esitetty paperikoneeseen kuuluva ns. superkaIanteri paperirainan kiillotukseen, joka kalanteri käsittää joukon kovia teloja ja olennaisesti yhtä suuren joukon pehmeitä teloja, kuten paperipääI lysteistä teloja, jotka ovat kovien telojen kanssa yhteistoiminnassa. Pääpatentin keksinnölle on olennaisesti tunnusmerkillistä se, että kovat telat ovat järjestetyt päällekkäin muodostamaan pinon, johon muodostuu kovia nippejä ja että kovien telojen muodostaman pinon ylimmän ja/tai alimman välitelan yhteyteen on kahden kovan telan välisen kovan nipin lisäksi muodostettu ainakin kaksi pehmeää nippiä, joiden toisena telana on pehmeä, sopivimmin paperipää I Iys-teinen tela.The main patent No. 58801 of the present application discloses a so-called a supercalender for polishing a paper web, the calender comprising a plurality of hard rolls and a substantially equal number of soft rolls, such as paper rolls, cooperating with the hard rolls. The invention of the main patent is essentially characterized in that the hard rolls are arranged one on top of the other to form a stack of hard nips and that in addition to the hard nip between two hard rolls at least two soft nips are formed in connection with is a soft, preferably paper head I I-tee roll.

2 602642 60264

Esillä olevan keksinnön tarkoituksena on aikaansaada parannuksia edellä määritellyssä kalanterissa ja muissa vastaavissa kalantereissa käytettyihin teloihin, etenkin pehmeisiin teloihin, jotka muodostavat pehmeitä nippejä yhdessä kalanteriin kuuluvien kovien teiojen kanssa. Pääpatentin mukaisessa kalanterissa tulevat pehmeät telat sijaitsemaan niin, että niiden akseli ja niiden muodostama nippikohta eivät sijaitse pystysuorassa tasossa.It is an object of the present invention to provide improvements to the rolls used in the calender and other similar calenders as defined above, in particular to soft rolls which form soft nips together with the hard tongs belonging to the calender. In the calender according to the main patent, the soft rollers will be located so that their axis and the nip point formed by them are not located in a vertical plane.

Lisäksi pehmeiden telojen kuormitus on järjestetty säädettäväksi. Näistä seikoista johtuen kyseisten telojen oman painon ja viivapainekuormituksen resultantin suunta tulee muuttumaan kalenterin nippien kuormitusta muutettaessa. Tällöin tulee kalanteritelojen taipuman ja tätä kautta kyseisten pehmeiden kalanteritelojen muodostamien nippien viivapaineen jakautuman säätö hyvin vaikeaksi ja hyvin monimutkaiseksi. Keksinnön tarkoituksena onkin saada aikaan uusi kalanteritela, jonka avulla voidaan edellä ilmenneet epäkohdat välttää.In addition, the load on the soft rollers is arranged to be adjustable. Due to these factors, the direction of the resultant of the own weight and line pressure load of the rolls in question will change as the load on the calendar nips changes. In this case, it becomes very difficult and very complicated to adjust the deflection of the calender rolls and thus the line pressure distribution of the nips formed by these soft calender rolls. The object of the invention is therefore to provide a new calender roll, by means of which the above-mentioned disadvantages can be avoided.

Edellä esitettyihin ja muihin päämääriin pääsemiseksi keksinnölle on pääasiallisesti tunnusomaista se, että toisella taipumakompensointi vyöhykkeellä kompensoidaan pääasiallisesti telan omasta painosta aiheutuva taipuma ja toisella taipumakompensointivyöhykkeelIä pääasiallisesti kalenterin nipin viivapainekuormituksesta aiheutuva taipuma.In order to achieve the above and other objects, the invention is mainly characterized in that in one deflection compensation zone the deflection mainly due to the roll's own weight is compensated and in the other deflection compensation zone the deflection mainly due to the line pressure load of the calendar nip.

Seuraavassa keksintöä selostetaan yksityiskohtaisesti viittaamalla oheisen piirustuksen kuvioissa esitettyyn keksinnön erääseen sovellutusesimerkkiin, johon keksintöä ei kuitenkaan ole mitenkään rajoitettu.The invention will now be described in detail with reference to an embodiment of the invention shown in the figures of the accompanying drawing, to which, however, the invention is in no way limited.

Kuvio I esittää kaaviollisena sivukuvana sellaista kalanteria, jossa keksinnön mukaista taipumakompensoitua telaa käytetään.Figure I shows a schematic side view of a calender in which a deflection-compensated roll according to the invention is used.

Kuvio 2 esittää poikkileikkausta keksinnön mukaisesta taipumakompensoidusta telasta.Figure 2 shows a cross-section of a deflection-compensated roll according to the invention.

Kuvio 3 esittää keskeistä aksiaaIiIeikkausta keksinnön mukaisesta taipumakom- pensoidusta telasta.Figure 3 shows a central axial section of a deflection compensated roll according to the invention.

Kuviossa I on esitetty eräs sellainen kalanterin suoritusmuoto, jossa keksinnön mukaista taipumakompensoitua telaa sovelletaan. Kalanterin telat 1,2,5 Ja 6 ovat kovia, esim. koki 11iteloja. Telat I ja 2 ovat suuri läpimittaisia teloja (säde Rj). Tela 2 on varustettu käyttölaitteella 40, joka on esitetty symboli- 3 60264 sesti. Tässä yhteydessä on syytä todeta, että telojen I ja 2 suuri läpimitta 2 R| tekee niiden taipuman kuitenkin varsin pieneksi, vaikka niitä kuormitettaisiin epäsymmetrisesti.Figure I shows an embodiment of a calender in which the deflection-compensated roll according to the invention is applied. Calender rolls 1,2,5 and 6 are hard, e.g., experienced 11 rolls. Rollers I and 2 are large diameter rollers (radius Rj). The roller 2 is provided with a drive device 40, which is shown symbolically. In this connection, it should be noted that the large diameter of the rolls I and 2 is 2 R | however, makes their deflection quite small even if they are loaded asymmetrically.

Telat 10 ovat ns. paperi tel oja, jotka ovat yleisesti superkaIantereissa käytettyjä ja ne on varustettu keksinnön mukaisesti myöhemmin selviävällä tavalla taipumakompensoinniI Ia. Taipumakompensoidut pehmeät telat I0 on myös varustettu kuviosta I näkyvin voima I aittein 28,29 ja vipuvarsin 30-33, jotka on akseleilla 35 ja 36 nivelöity ka Ianterirunkoon ja joiden avulla telat 10 voidaan siirtää sopivan välin päähän telan I, vastaavasti 2, pinnasta. Teloja 10 voidaan voimalaitteilla 28,29 puristaa kovia teloja I ja 2 vastaan kalanteri-nippien N halutun viivapaineen saavuttamiseksi.The rollers 10 are so-called paper rolls which are commonly used in supercalenders and which, according to the invention, are provided in a manner which will be explained later in the deflection compensation. The deflection-compensated soft rolls I0 are also provided with the force I devices 28,29 shown in Fig. I and the lever arms 30-33, which are articulated to the cover body by shafts 35 and 36 and by means of which the rollers 10 can be moved at a suitable distance from the surface of the roll I, 2, respectively. The rollers 10 can be pressed against the hard rollers I and 2 by means of power devices 28, 29 to achieve the desired line pressure of the calender nips N.

Pehmeiden telojen 10 sijoitustci ja niihin varsilla 30-33 kohdistettavaa voimaa vaihtelemalla voidaan pehmeiden nippien N nippipaineiden lisäksi vaikuttaa varsin laajoissa ja vaihtelevissa rajoissa myöskin kovien nippien N nippipai-neisiin. Näin ollen voimalaitteiden 28,29 työpaineiden Pj ja erotusta ja keskinäistä suhdetta vaihtelemalla voidaan vaikuttaa hyvin laajoissa rajoissa kaIanterointitapahtumaan. Paineiden Pj ja P^ säätölaitteita on kaavioi Iisesti esitetty kuviossa 2 lohkolla 50. Rainan kulkua kuviossa I esitetyssä kalenterissa on havainnollistettu nuolin W. -W ,.By varying the position of the soft rolls 10 and the force applied to them on the arms 30-33, in addition to the nip pressures N of the soft nips, the nip pressures N of the hard nips can also be influenced within quite wide and variable limits. Thus, by varying the operating pressures Pj of the power plants 28.29 and the difference and mutual relationship, the calendering event can be influenced within a very wide range. The pressure control devices Pj and P ^ are schematically shown in Fig. 2 by block 50. The course of the web in the calendar shown in Fig. I is illustrated by the arrows W. -W,.
