Definitions

  • the invention relates to a Crescentformer for a machine for producing a Tissuebahn according to the preamble of claim 1. It further relates to a method according to the preamble of claim 11.
  • Tissue manufacturing twin-wire formers and crescent formers the fiber suspension is placed between two dewatering belts, which passed over at least part of the circumference of a forming roll are.
  • twin-wire formers both drainage tapes are considered Drainage screens executed.
  • in Crescentformern as réellesieb provided a felt tape. Looking in the direction of flow after the forming roller, the outer belt is led away from the inner band.
  • the Tissuebahn formed between the two Entskyssansansbändem runs with the lower drainage band with. This is problematic Separation process when the outer band is very rough and / or very open. This is different when using a sieve with zonal Sieve permeability, i. when using a so-called DSP screen the case.
  • the fibers are partly due to the drainage flow drawn into the drainage tape where they get caught. This initially brings with it the disadvantage that the tissue web to tends to run with the outer screen. Another disadvantage is that the In the outer sieve, fibers do not fully entangle with the tissue web during the separation process be removed from the rough, open Aussensieb, but partly in the outer sieve remain. In operation, this leads to an increasing contamination of the outer sieve and thus to quality losses of the formed course as well as to runability problems in the Tissue machine.
  • the aim of the invention is to provide a former and a method of the type mentioned create a reliable and safe operation of a tissue machine with a Ensure DSP sieve in the initial drainage area.
  • a suction for example, a suction box with strips and Suction slots, a suction roll and / or a pipe suction can be used.

Thereafter, the screens in question may e.g. consist of a fabric in which provided in one or more levels Longitudinal and transverse threads according to a predeterminable pattern interwoven, that systematically distributed areas more suitable Showing size in which the number of intersections equal Zero or significantly smaller than in the weave structure of the remaining fabric.
  • the former according to the invention is the existing vacuum in the vacuum element adjustable. This is one easy adaptation to the respective operating conditions (Basis weight, porosity of the web, speed) possible.
  • the suction element is in the direction of tape expediently before Separation point arranged.

  • the vacuum in question adjustable again.
  • the adjustable Vacuum can be the contact intensity between the tissue web and change the inner band and adjust.
  • a higher vacuum For example, the adhesion of the web to the outer band is reduced and increased on the inner band, whereby the separation improved accordingly becomes.
  • the dewatering with zonal different screen permeability i. the DSP sieve, a conditioning device as assigned in particular a sieve cleaning device.
  • a conditioning device as assigned in particular a sieve cleaning device.
  • the DSP screen is counteracted due to the fact that due to the different permeability Fibers penetrate into the volume of the sieve and solidify.
  • a corresponding contamination affects the performance of the screen and thus the quality of the tissue web.
  • spray tubes with over the machine width arranged nozzles are used. It is, for example a traversing "Duocleaner" (see EP-A-0 731 212) of Voith Sulzer with rotating high pressure nozzles and integrated suction or a "Jet Cleaner” from Voith Sulzer can be used.
