  • the nip 10 is formed here by the Yankee drying cylinder 7 and the suction press roll 9.
  • the line force generated in the nip is 120 kN / m or less, so that dewatering of the tissue paper web 3 'and subsequent transfer of the tissue paper web 3' from the felt 11 to the Yankee drying cylinder 7 are accomplished by the nip 10.
  • FIG. 11 shows the tissue paper web 3 'passing through the nip 10.
  • the press roll 9 Since the press roll 9 has bores 30 in its lateral surface which communicate with the suction zone 12 of the press roll 9, rewet in the nip opening is prevented, thereby increasing the dry content of the tissue paper web 3 '.
  • the holes further ensure a good transfer of the tissue paper web 3 'to the Yankee drying cylinder 7. Further, the press roller 9 is driven, whereby the transfer of the tissue paper web 3 'from the felt 11 to the Yankee drying cylinder 7 is further improved.
  • a drying hood 33 can additionally be arranged above the Yankee drying cylinder 7 in such a way that the tissue paper web 3 'is guided between the drying hood 33 and the jacket surface 6 of the Yankee drying cylinder 7.
  • tissue paper web 3 ' has a much more compact structure than the tissue paper web 3 formed with the configuration of Figure 1, the tissue paper web 3' is free from the danger of being marked in the nip 10 due to the bores 30 and 31.
