Definitions

  • the machine according to the invention is preferably used for the production of fibrous webs with basis weights in the range between 35 g / m 2 and 120 g / m 2 and filler contents between 10% and 40% with web speeds up to 2400 m / min and more.
  • the shoe press has a shoe length of 270 mm or more, preferably 300 mm or more, and more preferably 330 mm or more.
  • the method is particularly preferably used for the production of fibrous webs having a basis weight between 35g / m 2 and 50g / m 2 and a filler content of between 10% and 25%, preferably between 15% and 18% with a web speed of 1600 m / min or more, preferably 2200m / min or more, and more preferably 2400m / min or more.
  • the method is preferably used for the production of fibrous webs having a basis weight between 50 g / m 2 and 60 g / m 2 and a filler content between 20% and 40%, preferably between 25% and 40% and with a web speed of 1600m / min or more , preferably 2000m / min or more, and more preferably 2200m / min or more.
  • the fibrous web 5 is transferred to a pick-up roller 10 from the lower wire 9 on an upper press felt 11 of the press section 3.
  • a pick-up roller 10 When transferring between Formierpartie 2 and press section 3 no free train on the fibrous web 5, since this is constantly supported by a fabric 9, 11.
  • the fibrous web 5 In the press section 3, the fibrous web 5 is guided in sandwich between the upper press felt 11 and a lower press felt 12 by only one press nip 13 formed by a shoe press 14 and thereby dewatered symmetrically.
