Definitions

  • the invention relates to a press section of a paper machine for thin Papers according to the preamble of claim 1, in particular for single-sided papers or tissue, in particular those Web acceptance at the last press unit.
  • a press nip which consists of a circumferential, smooth surface in contact with the paper and is formed from a felted press roll, the smooth surface transfers the, avoiding a free paper pull Paper web behind the press nip to a heatable roller, the smooth one Surface as the outer surface of a tubular roller with a rigid roller jacket is trained.
  • the felted press roll has an extended nip or Shoe press roller is.
  • the suction zone is mainly in front of the pre-press nip.
  • the smooth tube roller may also be advantageous to design the smooth tube roller as a deflection adjusting roller in order to maintain uniform line pressures and thus improve web transfer.
  • a further advantageous embodiment of the press section results if the heatable roller is a non-felted tube roller guiding the web, which delivers the web to a drying cylinder, preferably avoiding the free paper draw.
  • the gap between the smooth tube roller and the heatable roller in particular a drying cylinder, can be opened to to facilitate starting without paper.
  • Figure 1 shows the last press unit of a paper machine with a smooth Central roller 1 (a tube roller - i.e. with a rigid outer jacket), with another roller 2 a penultimate press nip together with a passes through single felt.
  • the roller 2 can be a suction roller or be a blind drilled roller.
  • the paper web then remains on the lie smooth roller 1 and is guided to a last press nip which by the roller 1 and an extended-nip press 3 are formed. After that the remains Paper web continues to lie on the smooth roller 1 and becomes a large one Smoothing cylinder 4, which can also be designed as a tissue cylinder, transferred according to the invention.
  • Figure 2 shows an arrangement similar to Figure 1, but is the last Press nip between the central roller 1, which is also a tube roller is formed, and the counter roll 3 not as an extended nip press but as so-called smoothing press executed.
  • the paper web also remains as in Figure 2 after the last nip on the smooth central roller 1 and is then transferred to a heated cylinder 4, for example.
  • a heated cylinder 4 for example.
  • FIG. 3 shows a special embodiment of the transfer according to the invention.
  • the beginning of a paper machine is shown here, in which stock suspension is injected between a screen 6 and a felt 10, which abut a blow roller 20, via a headbox 11.
  • the paper web is transported lying on this felt up to the press nip, which is formed here by an extended nip press 3 and the smooth tube roll 1 according to the invention. Possible devices between the press nip and the headbox are not shown here.
  • the paper web is transferred directly to a subsequent cylinder 5 via the smooth roller 1.
  • the roller 1 can preferably be designed as a deflection adjusting roller in order to ensure a pressure which is as uniform as possible, in particular on the following cylinder 5.
  • Figure 4 shows a situation at the last press nip of a press section.
  • a press unit between two cylinders 1 and 3 is shown here, the cylinder 1 representing the smooth cylinder according to the invention with a dimensionally stable surface.
  • the two cylinders 1 and 3 are provided here according to the invention on a movable lever arm 40, so that they can be moved in and out in their entirety by the subsequent large cylinder 30 without the press nip between the two cylinders 1 and 3 changing.
  • Figure 5 shows a further variant of the invention. It's coming from the left a felt 10 carrying a paper web 100 is shown.
  • the felt 10 leads the Paper web from above over a cylinder 300, the one with the following smooth tube roll 1 according to the invention forms a penultimate press nip. While after the penultimate press nip the paper web goes directly to the last one Press nip between the smooth tube roll 1 and the subsequent roll 600 is guided, the felt runs over a conditioning device 8 and Deflection roller 400 separated from the paper web back to the last one Press nip over the roller 600 and is returned from there during the Paper web remains on the smooth roller 1 and directly to the subsequent drying cylinder 7 is passed.
  • Figure 6 shows a press unit according to the invention of a compact design. It is here 11 stock suspension between a felt and a headbox introduced a smooth tube roller 1. One lies on the smooth tube roller 1 Long nip press 3 and then again on the smooth roller next smooth roller 1 ', the paper web to the subsequent station of the Convicted paper machine.
  • FIG. 7 shows the arrangement according to the invention using the example of a Paper machine for the production of crepe paper. It's from the right coming tape 500 to see on which the paper web is guided. The The tape is passed together with the paper web over a suction roll 200, which passes the paper web to a profile roller 1 with a rigid jacket. While the belt 500 is being fed back via a deflection roller, the paper web remains on the profile roller 1 and becomes a press nip, formed by the profile roller 1 and an extended nip press 3, supplied by where it remains on the surface of the profile roller and then on a crepe cylinder 4 is transferred, which rests on the profile roller 1.
