Definitions

  • the invention relates to a machine for producing a fibrous web, in particular a tissue paper web, with at least one shoe press unit and a press comprising a drying cylinder to form an elongated one Press nip.
  • the fibrous web is at least one upstream Press nip led to drainage, the fibrous web between both press nips runs together with a waterproof tape.
  • shoe press units offer the advantage of an effective one and volume-saving drainage, which is particularly true for tissue papers is essential.
  • the degree of drainage depends on the pressing pulse as an integral of the pressing pressure over the pressing time the influence on the volume determined by the pressure maximum in the press zone. It is transported from the forming wire of the machine through both press points with a waterproof tape. This band prevents one Rewet the fibrous web, however, due to the lack of water absorption make no contribution to the drainage in the press stations. For this reason, the upstream press nip makes it water-absorbing Felt led. This means that drainage is essentially takes place in this press nip. These machines are therefore not only unsatisfactory in terms of drainage performance but also the effort.
  • the object of the invention is therefore to provide a simple machine Production of a fibrous web, in particular a tissue paper web create a structure that is simple and as intensive and volume-saving as possible Drainage guaranteed.
  • the object was achieved in that through the press nip in addition to the fibrous web at least one water permeable and - Receiving tape in the form of a sieve, felt or the like and that Tape passed in front of the press nip over at least one suction device becomes.
  • the suction device By using the suction device, it is possible to suffice Remove water from the belt and possibly even the fibrous web, so that the water absorption capacity of the tape is sufficient to the Press nip to take out squeezed water. It also remoistens the fibrous web is reduced.
  • the drying cylinder can also be used as a tissue drying cylinder can be used, the fibrous web after Drying preferably from the drying cylinder using a crepe scraper is scraped off.
  • the tape should go together with the fibrous web over the suction device are performed, the fibrous web outside, d. H. on the non-vacuumed Side of the tape.
  • a suction device a vacuumed roller.
  • Suctioned rolls generally consist of a perforated roll shell inside either by direct connection to a vacuum source or by vacuuming the non-looped area of the roller a negative pressure is produced.
  • These rollers are of a simpler design than those frequently used in Such machines used suction presses, because these must be more stable and may even have support elements.
  • the shoe press unit at least transversely to the web running direction has several press zones that are independent can be controlled from each other. This enables the setting of a Desired pressing force profile transverse to the direction of web travel regardless of the deflection of the drying cylinder. As a result, the drying cylinder also not be cambered, which simplifies production.
  • the increased temperature of the drying cylinder also ensures that the Viscosity of the water in the press nip is reduced and thus drainage is improved.
  • FIG. 1 shows a schematic Partial view of a machine for producing a tissue paper web.
  • a so-called forming roller 11 together an endless Volume 5 in the form of a felt and another, endless forming fabric 12 performed, but only the belt 5 runs entirely around the forming roller 11.
  • the inlet gap between the felt and the forming fabric 12 is by means of a known headbox 8 introduced the fiber suspension.
  • Which the fibrous web 1 that is formed after the wrapping area Forming roller 11 together with the belt 5 up to an extended press nip 4 continued. Before reaching the press nip 4, the belt 5 loops however, a suction device 6 in the form of a suction roller.
  • This vacuumed roller removes a substantial part of the water from the Volume 5 and possibly even something from the outer fibrous web 1. This increases the water absorption capacity of the belt 5 considerably, so that it is in the following extended press nip 4, through which it together with the Fiber web 1 runs, which can absorb squeezed water. This intensifies the drainage in such a way that you can get by with only one press nip 4.
  • the extended press nip 4 is a drying cylinder 3, the tissue drying cylinder serves, and a shoe press unit 2 is formed.
  • the Shoe press unit 2 consists essentially of a flexible roll shell and a pressing device 10, the concave pressing surface of a pressure shoe is formed.
  • the pressure is usually hydraulic and the lubrication between roller jacket and pressure shoe on hydrostatic and / or hydrodynamic manner.
  • the shoe press unit 2 points across Web direction 7 several independently controllable press zones on. This enables an adaptation to the bending of the drying cylinder 3 and the setting of a desired baling pressure profile transverse to the web running direction 7 possible.
  • the extended press nip 4 allows an intensive and yet Volume-saving drainage of the fibrous web 1.
  • the fibrous web 1 runs on the heated drying cylinder 3 along.
  • the drying is in this loop area by a Drying hood 13, which blows hot, dry air onto the fibrous web 1 and vacuumed again, intensified.
  • the fibrous web 1 After drying of the fibrous web 1, the fibrous web 1 is from Drying cylinder 3 removed via a known crepe doctor 9. The creped Fibrous web 1 can then be further processed and wound up.
