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 for formation an extended press nip, with the press nip next to the Fibrous web at least one water permeable and absorbent Band is guided, and the band together with the fibrous web is guided over at least one suctioned device, the fibrous web is outside.
  • Such a machine is for example in DE 42 16 264 C2 and also described in WO 97/16593.
  • the suctioned used Devices are used to remove the respective fibrous web from a sieve or a web, a functional interaction between this suction device and the shoe press unit is not intended.
  • shoe press units offer the advantage of a effective and volume-saving drainage, which is particularly the case with Tissue papers are essential.
  • the degree of Drainage from the pressing pulse as an integral of the pressing pressure over the Press time depends, the influence on the volume of the pressure maximum determined in the press zone. It is transported from the forming wire the machine through both press points with a water impermeable Tape. Although this tape prevents rewetting of the fibrous web, can, however, because of the lack of water absorption make no contribution to dewatering in the pressing points.
  • the upstream press nip the reason is that it absorbs water Felt led. That means that the drainage is essentially in this press nip takes place.
  • the object of the invention is therefore a machine for producing a To create fibrous web, in particular a tissue paper web, the is simple and as intensive and volume-saving as possible Drainage guaranteed.
  • the object was achieved in that the suction Device sufficient water from the belt and possibly the Fibrous web removed to create a water for the squeezed in the press nip to create sufficient water absorption capacity of the belt.
  • the result is a simply constructed machine that can be operated with just one Press nip can get by. At the same time it is possible to put the tape in Shaped part for receiving the fiber suspension from a headbox to use. This eliminates the need to hand over the Fiber web between different belts.
  • the Drying cylinders are used as tissue drying cylinders, the After drying, the fibrous web is preferably over a crepe scraper is scraped off the drying cylinder.
  • a suction roller is particularly suitable as the suction device in particular is directly upstream of the shoe press unit.
  • 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 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 Band 5 in the form of a felt and another, endless forming fabric 12 out, 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.
  • the belt 5 loops however, a suction device 6 in the form of a suction roller.
  • This suctioned 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 Fibrous 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 fibrous web 1 runs on the heated drying cylinder 3 along. Drying is still carried out in this loop area Drying hood 13, which blows hot, dry air onto the fibrous web 1 and vacuumed again, intensified.
