Definitions

  • the invention relates to a machine for producing and / or finishing the fibrous web with at least one nozzle whose water jet is directed onto the fibrous web, according to the preamble of claim 1.
  • a machine for producing and / or finishing the fibrous web with at least one nozzle whose water jet is directed onto the fibrous web, according to the preamble of claim 1.
  • Such a machine is made EP 1148172 A known.
  • the fibrous web is supported on the opposite side when cutting with a jet of water. This support takes place at the US-A1 2001/0004007 through a sieve or even through a cutting table. During operation, soiling of the supporting surfaces by the fibers or the additives of the fibrous web occurs. In addition, the high pressure of the water jet over time also leads to the wear of the surfaces hit by the water jet.
  • ansgesitzunge cutting table therefore often has an opening for the removal and suction of impurities and water.
  • the separated strip is supported by vacuum sucked into a discharge funnel. This is very expensive, in particular with regard to the cleanliness of the cutting table and the removal of the strip.
  • the object of the invention is therefore to simplify the structure of the cutting device with at least constant reliability.
  • the elaborate cutting table can thus be reduced to a support plate.
  • the support plate is very simple and ensures during cutting sufficient support of the fibrous web in the cutting area, the support plate has a recess for the water jet, so that it can pass unhindered.
  • the cut edge strip falls down after the cutting area of the support plate.
  • the run of the severed strip should be influenced by a guide device preferably in the form of a guide plate and / or a guide part of the support plate and / or a compressed air and / or a water jet nozzle.
  • the support plate In order to prevent damage to the fibrous web and to counteract the accumulation of dirt, the support plate should form a flat as possible sliding surface, which runs approximately parallel to the fibrous web.
  • the fibrous web should, at least in the unloaded state, run along the support plate through the water jet at a distance. Because of the flat and preferably smooth sliding surface a sliding of the fibrous web during cutting remains without negative effect. It has proven to be advantageous if the distance between the fibrous web and the sliding surface of the support plate, in particular in the unloaded state in the range of 0 to 2 mm, preferably between 0 and 0.5 mm.
  • the rejects and parts of the fibrous web are collected and fed to pulp processing for recycling. Since the guide device supports the feeding of the severed strip into the pulper, expensive suction devices for guiding the separated edge strip can be saved.
  • the nozzle and / or the support plate and / or the guide device should be made adjustable with respect to their position.
  • the water jet cutting device can be arranged in the free train of the fibrous web, in the area of the dryer section. In the open train, the fibrous web runs without being supported on a belt, a roller or the like.
  • the installation position can be realized particularly simply on account of the pulper position at the end of a drying group, preferably after the last drying cylinder of the drying group, which is why the water jet cutting device should also be used there.
  • the water-jet cutting device can advantageously be arranged between one, in particular the last drying cylinder of the drying group and a following guide roll.
  • the fibrous web 1 runs in a dryer section of a paper machine for drying the same usually alternately over heated drying cylinders 4 and evacuated guide rollers 11.
  • the fibrous web 1 is guided by at least one dryer 8 of the respective drying group, wherein the fibrous web 1 comes into contact with the drying cylinders 4.
  • the fibrous web 1 comes into the region of the water jet cutting device, this being arranged between the drying cylinder 4 and a following guide roll 5.
  • This water jet cutting device consists essentially of a nozzle 2, which is arranged above the fibrous web 1 and the water jet is directed approximately perpendicular to the fibrous web 1.
  • To support the fibrous web 1 is located on the opposite side of a support plate 3.
  • This support plate 3 has a flat and smooth surface and is about 0.5 mm away from the fibrous web 1 in the unloaded state. During cutting, however, the fibrous web 1 is pressed against the support plate 3.
  • the support plate 3 according to Figure 2 has a recess 12 for the water jet.
  • the support plate 3 also includes a guide member 10, which supports the forwarding of the separated edge strip in the pulper 6 of the dryer section.
  • the support plate 3 extends parallel to the run of the fibrous web 1, it offers no possibility for attachment of fibers and other contaminants.
  • the separated strip 7 is guided into the arranged below the water jet cutter pulper 6 of the dryer section.
  • the collected pulp web remnants can thus be recycled.
  • a compressed air or water nozzle 9 blows the strip 7 in the direction of pulper 6 on the drying cylinder 4 adhering fibrous web residues are also from a scraper 13 from the drying cylinder 4th away.
  • the fibrous web 1 passes into another area of the paper machine, for example, for brushing or smoothing the fibrous web. 1
  • the water jet cutting device is very simple and saves a lot of energy because of the running without a suction edge trim removal taking into account the continuous operation.
