Abstract

Esillä olevan keksinnön esimerkinomaisen suoritusmuodon mukaan tuotetaan laite suuribulkkisen kuitupitoisen rainan tuottamiseksi, joka laite käsittää rainanmuodostusyksikön (1) kuitupitoisen rainan tuottamiseksi, kääntötelan (7) ja läpäisevän kankaan (2) rainan siirtämiseksi rainanmuodostusyksiköstä (1) läpäisevän kankaan tukemana kääntötelalle (7), joka tuottaa rainan kääntämisen vaakasuoraan suuntaan siten, että raina sijaitsee läpäisevän kankaan (1) ja kääntötelan (7) välissä. Imulaatikko (8), joka tuottaa alipaineen, on järjestetty rainan ja kankaan vastakkaiselle puolelle suhteessa kääntötelaan kankaan (2) ja kääntötelan (7) välisen etäisyyden sekä kankaan (2) ja kääntötelan (7) välissä kulkevan rainan paineen ohjaamiseksi.
