Definitions

  • the invention relates to a press unit of a paper machine for thin papers, in particular single-sided papers or tissue, in particular the web take-off on the last press unit.
  • the web is removed from the smooth roll in free train, e.g. a smoothing press, a drying cylinder or an in-line dryer section.
  • the inventors propose to remove the web from the smooth roll of the last press instead of the free train by means of a tube press roll, i.e. a roll with a rigid jacket, and to the next machine group e.g. the smoothing press, smoothing press, the drying cylinder or a batch dryer section.
  • the heatable roll e.g. a drying or smoothing cylinder
  • the heatable roll does not come into contact with either a felt or a "press hose” or “press jacket”.
  • the felt only has to pass through a single press nip. This results in a longer label life for both the press jacket and the felt.
  • a press nip is provided, which is formed from a circumferential, smooth surface in contact with paper and from a felted press roll, which transfers the smooth surface while avoiding a free one
  • the felted press roll is an extended nip or shoe press roll. Furthermore, it is particularly advantageous if, in the case of a press section designed in this way, the smooth tube roll in front of the press nip forms a further, preceding press nip (pre-press nip) with another felted press roll. Here it is also advantageous if for both
  • Press nips each a separate, endless felt is provided; however, a single felt for both press nips can be advantageous due to the operating conditions. It can be particularly advantageous with regard to the drying performance if the further felted press roll is also a shoe or extended-nip press roll.
  • the further felted press roll is a suction roll, the suction zone of which is predominantly in front of the pre-press nip.
  • the smooth tube roll may also be advantageous to design the smooth tube roll as a deflection setting roll in order to obtain 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. It can also be advantageous here if the heatable roll forms an after-press nip with an additional, felted press roll.
  • Figures 1 to 7 show variants of a web transfer between the press unit and the subsequent paper machine with smooth rollers.
  • Figure 1 shows the last press unit of a
  • Paper machine with a smooth central roller 1 (a tube roller - that is to say with a rigid outer jacket) which, with another roller 2, forms a penultimate press nip together with a single felt running through it.
  • the roller 2 can be a suction roller or a blind-drilled roller.
  • the paper web then remains on the smooth roller 1 and is guided to a last press nip which is formed by the roller 1 and an extended nip press 3. Thereafter, the paper web remains on the smooth cylinder and is designed according to the invention to form a large smooth cylinder 4, which can also be designed as a tissue cylinder.
  • Figure 2 shows a similar arrangement as Figure 1, but the last press nip between the central roll 1, which is also designed as a tube roll, and the counter roll 3 is not designed as an extended nip press but as a so-called smoothing press.
  • the paper web also remains on the smooth central roller after the last press nip 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 two screens which are in contact with a blowing roller via a headbox.
  • the paper web is lying on this first felt up to the last press nip, which is here through a long nip press 3 and the invention smooth tube roll 4 is formed, transported further. Possible devices between the last press nip and the headbox are not shown here.
  • the paper web is transferred directly to a subsequent cylinder 5 via the smooth roller 4.
  • the roller 4 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 2 is shown here, the cylinder 2 representing the smooth cylinder according to the invention with a dimensionally stable surface.
  • the two cylinders 1 and 2 are provided here according to the invention on a movable lever arm 4, so that they can be moved in and out in their entirety by the subsequent large cylinder 3 without the press gap between the two cylinders 1 and 2 changing.
  • Figure 5 shows a further variant of the invention.
  • a felt 2 carrying a paper web 1 is shown.
  • the felt 2 guides the paper web from above to a cylinder 3 which forms a penultimate press nip with the subsequent smooth tube roll 5 according to the invention.
  • the felt runs via a conditioning device 8 and a deflection roll 4 separately from the paper web back to the last press nip via the roll 6 and returned from there while the paper web remains on the smooth roller 5 and is transferred directly to the subsequent drying cylinder 7.
  • Figure 6 shows a press unit according to the invention of a compact design.
  • FIG. 7 shows the arrangement according to the invention using the example of a paper machine for producing crepe paper.
  • a tape 5 coming from the right can be seen on which the paper web is guided.
  • the tape is passed together with the paper web over a suction roller, which transfers the paper web to a profile roller 1 with a rigid jacket. While the tape 5 is returned via a deflection roller, the paper web remains on the profile roller 1 and is formed into a press nip by the profile roller 1 and an extended nip press 3, from where it continues to remain on the surface of the profile roller and then on a crepe cylinder 4 is transferred which rests on the profile roller 1.
