Definitions

  • the invention relates to a press unit of a paper machine for the production of tissue paper.
  • a press unit of a paper machine with a plurality of press nips for dewatering a paper web is known.
  • the paper web is guided together with a first felt belt through a first press nip between two dewatering rollers, at least one of which is designed as a suction roller with suction zones.
  • the paper web then runs together with the first felt belt through a second press nip which is formed by a roller with a smooth surface and the suction roller. Dewatering of the paper web in the second press nip takes place through the felt into the suction roll. While the felt belt is being guided away from the smooth roller, the paper web remains on its surface and is subsequently passed through further press nips for further dewatering.
  • a disadvantage of this device is the very low drainage capacity, particularly when producing tissue webs.
  • the object of the invention is to present a press unit of a tissue paper machine which has a particularly high drying capacity.
  • the press unit has a long-shoe press and a suction or grooved roller, which is arranged in the direction of travel of the web and arranged in front of the long-shoe press, which dehumidifies the press felt.
  • Figure 1 Press device according to the invention.
  • FIG. 1 shows a press device of a paper machine for producing a tissue web with a long-shoe press.
  • a felt 1 is shown with running direction 1.1, on which one Paper web 2 is arranged horizontally.
  • the felt is introduced via a press roll 3 designed as a suction roll into a press nip between the press roll 3 and a press roll with a smooth surface 4, the felt being freed of water by a suction zone before entering the press nip.
  • the felt After passing through the press nip between the rollers 3 and 4, the felt, together with the paper web on the press roller 4, is introduced directly into a press nip of a long-shoe press, the long-shoe press being made from a shoe press unit 5 with a stationary press shoe - to make it impermeable Press belt or a press jacket runs - and the press roll 4 provided as a counter roll exists.
  • the felt 1 is returned via 2 or more deflection rollers 7 and 8, while the paper web 2 continues to run on the press roll 4 and directly into the next press nip between the drying cylinder 6 and the adjacent one Press roll 4 is guided.
  • the drying cylinder can immediately be designed as a crepe cylinder.
  • the press roll 3 can be designed according to the invention as a suction roll or as a grooved roll and the press roll with a smooth surface 4 can be a rigid roll or a roll with deflection compensation.
