KUIVAPAPERIKONE - TORRPAPPERMASKINDRY PAPER MACHINE - TORRPAPPER MASK
Tämän keksinnön kohteena on kuivapaperikone, jossa muodos-tusosan jälkeisessä vaiheessa kuituraina on johdettu yläpuolisten ja/tai alapuolisten viirojen avulla koneen läpi sideaineen lisäystä, kuivausta ja polymerointia varten.The present invention relates to a dry paper machine in which, in the post-forming section, the fibrous web is passed through the machine by means of upper and / or lower wires for the addition, drying and polymerization of a binder.
Kun kovettumatonta rainaa käsitellään ja siirretään, on noudatettava varovaisuutta sen heikon lujuuden takia. Paperikoneissa, joissa seisokit ovat kalliita, tämä on erityisen tärkeätä. Nykyisissä kuivapaperikoneissa on rainan radassa ns. avoimia kohtia, joissa rainaa ei tueta lainkaan.When handling and transferring uncured web, care must be taken due to its poor strength. On paper machines where downtime is expensive, this is especially important. Current dry paper machines have a so-called open points where the web is not supported at all.
Näissä kohdissa syntyy jännityksiä rainaan ja se katkeaa, ellei rataa ajeta alhaisella nopeudella. Nykyisillä kuiva-paperikoneilla on siten huono kayntihyötysuhde, koska on joMduttu tekemään rainan katkeamisalttiuden ja koneen läpivientinopeuden välillä kompromissi.At these points, stresses are created in the web and it breaks unless the web is run at a low speed. Current dry paper machines thus have poor operating efficiency because a compromise has had to be made between the susceptibility of the web to break and the throughput speed of the machine.
Tämän keksinnön tarkoituksena on poistaa edellä mainitut haitat. Tämän vaikutuksen aikaansaamiseksi keksinnölle on tunnusomaista se, että yläpuoliset ja alapuoliset viirat sijaitsevat limittäin niin, että raina kulkee lepotilassa ilman jännityksiä aiheuttavia avoimia kohtia koko prosessin läpi.The object of the present invention is to eliminate the above-mentioned disadvantages. To achieve this effect, the invention is characterized in that the upper and lower wires overlap so that the web passes at rest without stress-causing open points throughout the process.
Keksinnölle on lisäksi tunnusomaista se, että valmiiksi sidottu raina kuumakalanteroidaan kuivausprosessin jälkeen.The invention is further characterized in that the pre-bonded web is hot calendered after the drying process.
Keksinnölle on vielä tunnusomaista se, että osittain sidottu raina kuumakalanteroidaan kuivausprosessin jälkeen.The invention is further characterized in that the partially bonded web is hot calendered after the drying process.
Tällä järjestelyllä saavutetaan se etu, että sideaineen imeytyminen toisessa vaiheessa tapahtuu tehokkaasti sumutusta edeltävän puristuksen ansiosta.This arrangement has the advantage that the absorption of the binder in the second stage takes place efficiently due to the pre-spray compression.
Keksintöä selostetaan seuraavassa esimerkin avulla viittaamalla oheiseen piirustukseen, jossa 2 68284The invention will now be described by way of example with reference to the accompanying drawing, in which 2 68284
Kuva 1 esittää keksinnön mukaista paperikonetta.Figure 1 shows a paper machine according to the invention.
Kuva 2 esittää keksinnön erästä toista sovellutusmuotoa.Figure 2 shows another embodiment of the invention.
Kuvan 1 mukaisessa paperikoneessa rata 1 siirretään muodostusviiralta 2 ensimmäisen kuivausviiran 3 alapintaan imulaatikon 4 avulla. Sen jälkeen sideaine 5 sumutetaan rataan 1 alapuolelta. Tässä vaiheessa rataa kannattaa imulaatikko 6. Sideainesumutuksen asemasta voidaan käyttää myös rainan muodostusvaiheessa lisättyjä komponentteja (kuumasaumautuvat hartsit tai vastaavat). Raina viedään edelleen yläpuolisen tyhjiön kannattamana (imulaatikko 7) ensimmäisen kuivausosan Θ läpi. Rata poimitaan kuviokalan-teriin 14 sileän telan avulla, mahdollisesti vettä tai höyryä hyväksikäyttäen kuivausviiran 3 alapinnalta ja viedään kuvio-kalanterinipin läpi.In the paper machine according to Fig. 1, the web 1 is transferred from the forming wire 2 to the lower surface of the first drying wire 3 by means of a suction box 4. The binder 5 is then sprayed from below the web 1. At this stage, the web is supported by a suction box 6. Instead of the binder spraying, the components added during the web-forming step (heat-sealable resins or the like) can also be used. The web is further passed through the first drying section Θ supported by an overhead vacuum (suction box 7). The web is picked up on the patterned fish blade 14 by means of a smooth roll, possibly using water or steam, from the lower surface of the drying wire 3 and passed through a patterned calender nip.
Tämän jälkeen rata siirretään kuviokalanterista 14 seuraa-valle viiralla 9 imulaatikon 10 avulla. Lopuksi raina viedään viiran 9 kannattamana toisen sideainesumutuksen 12, kuivausosan 0 ja polymerointiosan 13 läpi.The web is then transferred from the pattern calender 14 to the next wire 9 by means of a suction box 10. Finally, supported by the wire 9, the web is passed through a second binder spray 12, a drying section 0 and a polymerization section 13.
Kuvan 2 mukaisella järjestelyllä suoritetaan kalanterointi vasta polymeroinnin jälkeen, kun raina on luja ja kestävä.With the arrangement according to Figure 2, the calendering is carried out only after the polymerization, when the web is strong and durable.
Alan ammattimiehelle on selvää, että keksintö ei rajoitu edellä olevaan esimerkkiin, vaan sitä voidaan soveltaa jäljempänä esitettävien patenttivaatimusten puitteissa.It will be clear to a person skilled in the art that the invention is not limited to the above example, but can be applied within the scope of the claims set out below.
