Edellå esitettyjen ja myohemmin esille tulevien pååmåårien saavuttami-seksi on keksinnon mukaiselle menetelmålle pååasiallisesti tunnusomais-ta, ettå ennen tåyden telan siirtåmistå vaihtoasemaan Coiset rullaus-kiskot, jotka ainakin osittain ovat rullauskiskojen jatkeena, siirre-5 tåån samaan kulmaan kiskojen kanssa, jolloin toinen pyorivå tela tai tåysi tela voi siirtyå jatkoskohdan yli.In order to achieve the objectives set out above and later, the method according to the invention is essentially characterized in that before the complete roll is moved to the exchange station, the Coiset rolling rails, which are at least partly an extension of the rolling rails, are moved at the same angle or a full roll may move over the joint.

Keksinnon mukaisen menetelmån toiselle edulliselle toteuttamisesimer-kille on pååasiallisesti tunnusomaista, ettå ennen tåyden telan siirtå-10 mistå vaihtoasemaan rullauskiskojen kulma såådetåån sellaiseksi, ettå toiset rullauskiskot, jotka ovat kiinteåt, muodostavat jatkeen rullaus-kiskoille siten, ettå tåysi tela voi siirtyå jatkoskohdan yli.Another preferred embodiment of the method according to the invention is mainly characterized in that before moving the complete roll to any of the exchange stations, the angle of the winding rails is adjusted so that the second winding rails, which are fixed, form an extension over the winding rails.

Keksinnosså aloitetaan radan rullaus tampuuritelalle rullaussylinteriå 15 vasten kohdassa, jossa tampuuritelaan kohdistuvan maan vetovoiman rul-laussylinterin keskipisteen suuntainen voimakomponentti on sopiva muo-dostaen viivakuormituksen.In the invention, the winding of the track on the spool roll is started against the winding cylinder 15 at a point where the force component in the direction of the center of the winding cylinder of the traction force applied to the spool roll is suitable to form a line load.

Voimakomponentin muuttaminen saadaan aikaan usealla eri tavalla, esim. 20 sååtåmållå rullauskiskojen eli -haarukoiden kaltevuutta. Tampuurikoon kasvaessa kaltevuutta pienennetåån sopivaksi.The change of the force component is achieved in several different ways, e.g. by adjusting the inclination of the rolling rails or forks. As the swab size increases, the slope is reduced to fit.

Paperirullaimen vaihto- eli siirtotapahtumassa ensiokiskoilta toi-siokiskoille esiintyvåt epåjatkuvuudet saadaan keksinnon mukaisesti 25 eliminoitua esim. aloittamalla rullaus suoraan kiskoilta.According to the invention, the discontinuities occurring in the exchange or transfer operation of the paper winder from the primary rails to the secondary rails can be eliminated, e.g. by starting rolling directly from the rails.

Kun tåysi tampuuri pyorii toisiokiskoilla, ensiokiskot voidaan siirtåå optimaaliseen kaltevuusasemaan viivapainetta ajatellen siten, ettå viivakuormitus eli viivapaine muodostuu halutuksi koko koneen poikki-30 suunnassa.When the full tampon rotates on the secondary rails, the primary rails can be moved to the optimal inclination position for line pressure, so that the line load, i.e. line pressure, is desired in the entire cross-machine direction.

Erååsså suoritusmuodossa kun tåysi tampuuri pyorii toisiokiskoilla, siirretåån se jarrutusasemaan, jonka jålkeen ensiokiskot voidaan siirtåå optimaaliseen kaltevuusasemaan viivapainetta ajatellen siten, ettå 35 viivakuormitus eli viivapaine muodostuu halutuksi koko koneen poikki-suunnassa. Tåsså suoritusmuodossa tampuurin koon kasvaessa rullauksen li 3 90522 edetesså ensiokiskojen kaltevuuskulroaa pienennetaån. Vaihto eli siirto toisiokiskoille tapahtuu siirtamalla toisiokiskot vastaavaan kaltevuus-kulmaan ens iokiskojen kanssa, jolloln korvaava tampuuri vierii jatkos-kohdan yli, jonka alkana ensid- ja toisiokiskot liikkuvat tahdistettui-5 na saataen viivakuormitusta kaltevuuskulmaan muuttamisen valityksella.In one embodiment, when the full tampon rotates on the secondary rails, it is moved to a braking position, after which the primary rails can be moved to the optimal inclination position for line pressure so that a line load, i.e. line pressure, is desired across the entire machine. In this embodiment, as the size of the spool increases, as the rolling li 3 90522 progresses, the slope flow of the primary rails is reduced. The exchange, i.e. transfer to the secondary rails, takes place by moving the secondary rails to the corresponding inclination angle with the primary rails, whereby the replacement tampel rolls over the splice point, at which point the primary and secondary rails move in synchronism, applying a line load.

Keksinndn mukaisella jarjestelmalla saavutetaan myos muita etuja. Esim. vaihtotapahtumaa rullauksen alussa ei ole ja kuormitustilanteen nåkee luonnossa tarkkailemalla kiskojen kaltevuutta.The system according to the invention also achieves other advantages. For example, there is no change at the beginning of rolling and the load situation can be seen in nature by observing the inclination of the rails.
