Abstract

Processing apparatus for treating a fiber web, comprises a belt of a belt run (2), and comprising a layered structure including a metallic outer layer (10), intended for contact with a fiber web to be treated, and a backing layer(s) (11) bonded to the metal layer's inner surface, and made of a flexible and/or compressible material. Processing apparatus for treating a fiber web, comprises a belt of a belt run adapted to travel around a guide component(s), outside the belt run being provided, a counter-component(s) creating a contact surface with the belt, such that between the belt and the counter-component is established a web processing zone, the web to be treated being passed through it. The belt of the belt run comprises a layered structure including a metallic outer layer, intended for contact with a fiber web to be treated, and a backing layer(s) bonded to the metal layer's inner surface and made of a flexible and/or compressible material. An independent claim is also included for a method of treating a fiber web with a processing apparatus, comprising using a layer-structured belt in the belt run; heating the metallic, relatively thin outer layer for a rapid transfer of heat to the presently treated web, its surface portion converting to a plastic state; and cooling rapidly, where polymers contained in the web convert from a plastic state to a glassy state and the conversion remains permanent.

HihnarakenneThe belt structure

Esillä olevan keksinnön kohteena on hihna kuiturainan käsittelyyn tarkoitettua käsittelylaitetta varten, johon käsittelylaitteeseen kuuluu ainakin yhden 5 ohjainelimen ympäri kiertäväksi järjestetty hihnakierto, jonka hihnakierron ulkopuolelle on järjestetty ainakin yksi hihnan kanssa kontaktipinnan muodostava vastinelin siten, että hihnan ja vastinelimen väliin muodostuu rainan käsittelyalue, jonka läpi käsiteltävä raina viedään. Keksinnön kohteena on lisäksi menetelmä kuiturainan käsittelemiseksi.The present invention relates to a belt for a fiber web processing device comprising a belt rotation arranged around at least one of the guide members, outside of which there is provided at least one contact element forming a contact surface with the belt, such that a web processing area is formed between the belt and the counter member. the web is exported. The invention further relates to a method for treating a fibrous web.

Esillä olevan keksinnön päämääränä on aikaansaada parannettu hihnaratkai-su, joka myötävaikuttaa käsittelyn tehokkuuteen ja hihnan ajettavuuteen.It is an object of the present invention to provide an improved belt solution that contributes to processing efficiency and belt runnability.

Tämän päämäärän saavuttamiseksi keksinnön mukaiselle hihnalle on tunnusomaista se, että hihna on kerrosrakenteinen, jossa on metallia oleva ulkoker-15 ros, joka on tarkoitettu kosketuksiin käsiteltävän kuiturainan kanssa, ja ainakin yksi metallikerroksen sisäpintaan kiinnitetty tukikerros. Keksinnön mukaiselle menetelmälle on puolestaan tunnusomaista patenttivaatimuksen 8 tun-nusmerkkiosassa esitetyt asiat.To achieve this object, the belt according to the invention is characterized in that the belt is a sandwich structure having a metal outer ply for contact with the fibrous web to be treated and at least one support layer attached to the inner surface of the metal layer. The method according to the invention, in turn, is characterized by the features set forth in the characterizing part of claim 8.

:; : 20 Muodostamalla yksi- tai useampiosainen tukikerros joustavaksi ja/tai kokoon- puristuvaksi aikaansaadaan etuina mm. se, että paine välittyy tasaisesti ni-\ : pissä ja hihnan värähtelyä saadaan vaimennettua parantaen hihnan stabiili- suutta ja siten ajettavuutta. Kerrosrakenteinen hihna edesauttaa myös hihnojen ja telojen välisestä hankautumisesta aiheutuvan melun vähentämistä.:; : 20 Advantages of forming a one or more part support layer to be flexible and / or compressible include: the fact that the pressure is uniformly transmitted at the nip and that the vibration of the belt is dampened, thereby improving the stability and thus the runnability of the belt. The sandwich belt also contributes to reducing noise caused by friction between the belts and the rollers.

Tukikerrosta käyttämällä saadaan metallikerros tehtyä ohuemmaksi kuin pelkkää metallihihnaa käyttäen ja tämä mahdollistaa prosessin tehostamisen kuumennettua metallihihnaa käytettäessä, koska lämpö voi siirtyä nopeasti hihnasta käsiteltävään rainaan, jonka pintaosa siirtyy plastiseen tilaan ja ; ] 30 jäähtyy sitten nopeasti, jolloin rainan sisältämät polymeerit siirtyvät plastises- Γ; ta tilasta lasitilaan ja muodonmuutos jää pysyväksi. Hihnan metallikerroksen kuumentamista ja lämmön nopeaa siirtymistä siitä rainaan voidaan edesaut- 2 113881 taa muodostamalla tukikerros lämpöä eristävästä tai huonosti johtavasta materiaalista. Tällöin lämpö siirtyy metallikerroksesta olennaisesti vain rainaan päin ja metallikerros jäähtyy samalla nopeasti. Rainassa lämpö siirtyy pintakerroksesta sisäänpäin, jolloin pintakerros jäähtyy nopeasti ja tätä edesaut-5 taa jäähtynyt metallihihna käsittelyalueen loppupuolella. Lisäksi ohuempi me-tallihihna parantaa taivutuskestävyyttä, jolloin ohjaustelojen halkaisijaa voidaan pienentää. Pelkällä metallihihnalla on nykyisin käytetty tyypillisesti paksuutta n. 0,6 mm kun keksinnön mukaisella tukikerrosta käyttävällä hihnalla metallikerroksen paksuus voi olla alle n. 0,3 mm ja edullisesti se voi olla n.By using a backing layer, the metal layer is made thinner than by using a metal belt alone, and this enables the process to be made more efficient when using a heated metal belt, since heat can be rapidly transferred from the belt to a web to be treated with a surface part; ] 30 then cools rapidly, whereby the polymers contained in the web are transferred to plastics; from space to glass and the deformation remains permanent. The heating of the metal layer of the belt and the rapid transfer of heat therefrom to the web can be facilitated by forming a backing layer of heat-insulating or poorly conductive material. In this case, the heat is transferred from the metal layer substantially only towards the web, while the metal layer cools rapidly. In the web, heat is transferred from the surface layer inwards, whereupon the surface layer cools rapidly and is assisted by a cooled metal belt towards the end of the treatment area. In addition, a thinner metal belt improves bending resistance, whereby the diameter of the guide rollers can be reduced. At present, a metal belt alone has typically employed a thickness of about 0.6 mm, whereas the support layer belt according to the invention may have a thickness of less than about 0.3 mm and preferably be n.
