1 EP3 540 119 KUITURAINAKONE JA MENETELMA MONIKERROKSISEN RAINAN MUODOSTAMISEKSI PATENTTIVAATIMUKSET1 EP3 540 119 FIBER FABRIC MACHINE AND METHOD FOR FORMING A MULTI-LAYER FABRIC PATENT CLAIMS 1. Menetelmä monikerroksisen rainan muodostamiseksi kuiturainakoneessa, joka menetelmä käsittää sen, että syötetään eri massasuspensioita monikerroksisen perälaatikon (1) diffuusoreihin (13, 15, 17, 19, 21), ohjataan eri massasuspensiot monikerroksisen perälaatikon diffuusorien (13, 15, 17, 19, 21) läpi niiden työntämiseksi muodostusosan (21) viiralle, jolloin — viira muodostaa suljetun silmukan, poistetaan vesi nestemäisistä aineista vähintään kolmikerroksisen rainan (51, 53, 55) muodossa olevan täytekerroksen muodostamiseksi, yhdistetään kyseinen vähintään kolmikerroksinen raina (51, 52, 55) toiseen rainaan (57, 59), joka on muodostettu toisessa perälaatikossa (23), joka työntää massasuspensiota toisen muodostusosan (25) viiralle, ja yhdistetään kyseinen vähintään kolmikerroksinen (51, 53, 55) raina kolmanteen rainaan (59), joka on muodostettu kolmannessa perälaatikossa (27), joka työntää massasuspensiota kolmannen muodostusosan (29) viiralle, jolloin kolmas raina (59) on järjestetty kolmikerroksisen rainan (51, 53, 55) sille puolelle, joka on vastakkainen siihen puoleen nähden, johon toinen raina (57) on järjestetty, tunnettu siitä, että kyseisen vähintään kolmikerroksisen rainan (51, 53, 55) vähintään yhden pintakerroksen (51, 53) massan ominaisuudet ja toisen rainan (57) tai kolmannen rainan (59) massan ominaisuudet vastaavat toisiaan.1. A method for forming a multilayer web in a fiber web machine, which method comprises feeding different mass suspensions to the diffusers (13, 15, 17, 19, 21) of the multilayer head box (1), directing the different mass suspensions to the diffusers (13, 15, 17, 19, 21) through them to push the forming part (21) onto the wire, whereby — the wire forms a closed loop, water is removed from the liquid substances to form a filling layer in the form of at least a three-layer web (51, 53, 55), the said at least three-layer web (51, 52, 55) is connected to another to the web (57, 59) formed in the second end box (23) which pushes the pulp suspension onto the wire of the second forming part (25), and connecting said at least three-layered (51, 53, 55) web to the third web (59) formed in the third end box (27), which pushes the mass suspension onto the wire of the third forming part (29), whereby the third web (59) is arranged on the side of the three-layer web (51, 53, 55) which is opposite to the side on which the second web (57) is arranged, characterized in that the mass properties of at least one surface layer (51, 53) of the said at least three-layer web (51, 53, 55) and the mass properties of the second web (57) or the third web (59) correspond to each other. 2. Patenttivaatimuksen 1 mukainen menetelmä, jossa eri massasuspensioilla on erilaiset koostumukset.2. The method according to claim 1, in which different mass suspensions have different compositions. 2 EP3 540 1192 EP3 540 119 3. Patenttivaatimuksen 1 tai 2 mukainen menetelmä, jossa eri massasuspensiot sisältävät 20-30 % BSW:tä, 50-70 % BCTMP:tä ja 20-30 % hylkyä.3. The method according to claim 1 or 2, where the different pulp suspensions contain 20-30% BSW, 50-70% BCTMP and 20-30% scrap. 4. Jonkin patenttivaatimuksista 1-3 mukainen menetelmä, jossa sisemmistä diffuusoreista (15, 17) ensimmäisen läpi johdetaan makeaa vettä, laimennusvettä ja/tai kiertovettä siten, että viiran päällä on vesikerros kerrostettuna kahden vierekkäisen massasuspensiokerroksen väliin.4. The method according to one of the patent claims 1-3, in which fresh water, dilution water and/or circulation water is led through the first of the inner diffusers (15, 17) in such a way that a layer of water is layered on top of the wire between two adjacent layers of mass suspension. 5. Patenttivaatimuksen 4 mukainen menetelmä, jossa sisemmistä diffuusoreista toisen (15, 17) läpi ohjataan myös makeaa vettä, laimennusvettä ja/tai kiertovettä, jolloin ensimmäisen (15) ja toisen (17) sisemmän diffuusorin väliin on järjestetty vähintään yksi diffuusori (13) siten, että viiran päällä on vähintään massasuspensiokerros kerrostettuna kahden vesikerroksen väliin.5. The method according to claim 4, in which fresh water, dilution water and/or circulation water is also directed through one of the inner diffusers (15, 17), whereby at least one diffuser (13) is arranged between the first (15) and the second (17) inner diffuser, so , that on top of the wire there is at least a mass suspension layer layered between two water layers. 6. Jonkin patenttivaatimuksista 4 tai 5 mukainen menetelmä, jossa sisemmistä diffuusoreista ensimmäisen (15) tai toisen (17) läpi ohjattuun makeaan veteen, laimennusveteen ja/tai kiertoveteen lisätään lisäaineita.6. The method according to one of claims 4 or 5, in which additives are added to fresh water, dilution water and/or circulating water directed through the first (15) or second (17) of the inner diffusers. 7.
