Definitions

  • a roll-blade former with or without flexible twin-mesh bars is used in conjunction with two freestanding shoe presses or a freestanding roller press and a subsequent shoe press in conjunction with a multi-pin calender.
  • the fibrous web passes through a drying section and is dried in this.
  • a drying section There are different ways to dry the fibrous web, for example by drying on heated cylinders or by Impallströmtrocknung with hot air.
  • Fibrous web is brought into contact in each case with a heated roller in a first sequence of Kalandemips and that the other of the two sides of the fibrous web is subsequently brought into contact in a second sequence of Kamémips each with a heated roller.
  • FIG. 1 shows a paper machine 1 for producing SC paper, which preferably has a filler content of 25% or more.
  • the fibrous web 2 is formed in the formed as a vertical gap former Formierpartie 3 in a stock inlet gap 7 between an upper Formiersieb 11 and a lower Formierieb 10. After the stock inlet gap 7 wrap around the sandwich consisting of upper Formiersieb 11, fibrous web 2 and lower Formiersieb 10 for draining the Fiber web 2 a forming roller 8 in the angular range between 30 ° and 60 °, preferably between 40 ° and 55 °.
  • the moistening takes place on the lower side 28 of the fibrous web 2 by means of a nozzle moistener 35, which is designed as a two-component nozzle moistener, from which an air-dampening solution mixture emerges.
  • the calender 6 is a same two-sided treatment of Fibrous web 2 instead. This is achieved by first bringing the lower side 28 of the fibrous web 2 in contact with one of the heating rollers 32 in a first sequence 37 of four Kamémips 33 and subsequently, after passing through the Kamémip 34, which is also referred to as an alternating gap, the upper side 27 of the fibrous web 2 is brought into contact with one of the heating rollers 32 in a second sequence 38 of four Kamémips 33.

Abstract

L'invention concerne un procédé de production d'une bande de papier ou d'une autre bande de matière fibreuse. La bande de matière fibreuse est soumise à une pression dans une avant-dernière ligne de contact entre deux rouleaux puis dans une dernière ligne de contact entre deux rouleaux d'une partie presse. Une face de la bande de matière fibreuse est mise en contact avec une surface lisse lors du passage par l'avant-dernière ligne de contact entre deux rouleaux. L'autre face de la bande de matière fibreuse est mise en contact avec une surface lisse lors du passage par la dernière ligne de contact entre deux rouleaux.
