Definitions

  • the invention relates to a press section of a paper machine according to the preamble of claim 1.
  • Press sections of this type have the decisive advantage that by using presses with an extended press length, viewed in the direction of web travel, a relatively long time is available for squeezing the liquid out of the web. In this way, such a press section can make do with few pressing points and still achieve a high dewatering effect, even when the paper web runs quickly.
  • the known presses with an extended press nip are often constructed in such a way that a press roll is provided with a flexible jacket which is pressed from the inside against a rigid mating roll by an essentially only radially movable press element, the flexible jacket pressing in the area of the press nip the rigid counter roller can nestle.
  • other embodiments for achieving an extended pressing surface are also conceivable.
  • the aim in high-speed machines is for the paper web to be in constant contact with at least one felt in order to avoid a so-called free pull, in which the paper web would run the risk of being torn off.
  • a disadvantage of such arrangements is that after the paper web has emerged from the press nip, rewetting by the water carried in the felt occurs in the paper web.
  • DE-OS 38 15 278 A1 shows a press with two roller presses one behind the other, each with an extended press nip, whereby the conditions for dewatering the paper web are favorable, but on the other hand the paper web is transported with the help of a felt through both press stations. So it cannot be conditioned between the two presses.
  • the invention has for its object to further improve the dewatering effect of press sections with two successive elongated press nips without thereby reducing the operational reliability of the web guide through both presses.
  • a particular advantage of the proposed solution is that different felts can be used for the two press points in this way. It is therefore possible to recondition each felt after it has passed through the pressing point, that is to say to provide it with a relatively low water content for a new pressing process.
  • the transfer of the web from the first bottom felt to the second top felt is carried out with the help of a felted and vacuum operated removal device. It is also ensured that the wet web can be safely guided between the press points mentioned and held on the felt.
  • a further advantage can be achieved if the paper web can be passed through the press points 1 and 2 with full width when starting the press section, because this serves to protect the sometimes sensitive components of the wide nip press rolls.
  • a transfer strip can be formed, for example for the subsequent dryer section. The committee that occurs thereby passes into the committee dissolver 23 below.
  • the reliable transfer between the first and second press is ensured by a suction box 16, which exerts a negative pressure on the felt above the upper felt 13 and thereby holds the web beneath it on the upper felt 13. From there, the web comes together with the upper felt into the second press point 2.
  • a suction box 16 instead of the suction box, a special blow box can also be used, which, according to the injector principle, creates an air flow in narrow slots with a direction away from the felt and exerts a holding effect on the web.
  • FIG. 5 Another embodiment of the press section according to the invention is shown in FIG. 5.
  • the removal device 15 operated with negative pressure leads the web in a direct manner from the counter roll 7 belonging to the first press point 1 to the counter roll 9 belonging to the second press point 2. After passing through the second press point 2, the web remains on the counter roller 9 to the further take-off point 18, while the upper felt 13 is removed from the web immediately after leaving the press point 5, 6.
  • the further removal device 18 leads the web directly into the subsequent dryer section.
