Definitions

  • the invention relates to a water jet cutting device for separating a Strip from a running paper, cardboard, tissue or other Fibrous web in a machine for producing and / or finishing the Fibrous web with at least one nozzle, whose water jet onto the fibrous web is directed.
  • the fibrous web is cut while avoiding tearing or even tearing Cutting with water jet supported on the opposite side.
  • This Support is usually provided by a cutting table. It happens during operation to contaminate the supporting surfaces by the fibers or additives the fibrous web.
  • the high pressure of the water jet leads in the course of the Time to wear out the surfaces hit by the water jet.
  • the cutting table therefore often has an opening to the water jet Removal and suction of impurities and water.
  • the severed Strips are sucked into a discharge funnel supported by vacuum. This is especially with regard to keeping the cutting table clean and the discharge of the strip very expensive.
  • the object of the invention is therefore the construction of the cutting device Simplify at least consistent operational security.
  • the object was achieved in that the water jet cutting device about over a pulper to catch the separated Strip of the fibrous web is arranged.
  • the cutting device needed in this Position in the paper machine no discharge and / or vacuum systems.
  • the complex 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 is unimpeded can pass through.
  • the cut edge strip falls from the support plate after the cutting point down.
  • the cut strip should run from one Guide device preferably in the form of a guide plate and / or one Guide part of the support plate and / or a compressed air and / or one Water jet nozzle can be influenced.
  • the support plate should be as level as possible Form a sliding surface that runs approximately parallel to the fibrous web.
  • the Fiber web at least in the unloaded state with the water jet run a distance along the gusset. Because of the level and preferably smooth sliding surface remains a sliding of the fibrous web during Cutting without negative effects. It has proven to be advantageous if the distance between the fibrous web and the sliding surface of the support plate especially in the unloaded state in the range of 0 to 2 mm, preferably is between 0 and 0.5 mm.
  • the rejects and parts of the fibrous web are collected in the pulper and the Pulp preparation fed for recycling. Because the guide supports the feeding of the separated strip into the pulper elaborate suction devices for guiding the separated edge strip be saved.
  • the nozzle and / or the Support plate and / or the guide device adjustable in terms of their position be designed.
  • the water jet cutting device can free pull of the fibrous web, be arranged in the dryer section. in the The fibrous web runs freely without moving on a belt, a roller or support similar.
  • the installation position is particularly easy due to the pulper position at the end a drying group, preferably after the last drying cylinder Realize dryer group, which is why the water jet cutting device there too should be used. After removing the dryer from the The water jet cutting device can thus advantageously be used between the dryer group one, especially the last drying cylinder of the drying group and one following guide roller may be arranged.
  • the fibrous web 1 runs in a dryer section of a paper machine for drying the same mostly alternately via heated drying cylinders 4 and suction Guide rollers 11.
  • the fibrous web 1 is thereby at least one drying wire 8th the respective drying group, the fibrous web 1 with the Drying cylinders 4 comes into contact.
  • the moisture content of the fibrous web 1 decreases and the Firmness too.
  • the Water jet cutting device for use. Because of the increased strength of the Fibrous web 1, this can be done in the free pull of the fibrous web 1.
  • the fibrous web 1 comes into the area of the water jet cutting device, this between the drying cylinder 4 and one following guide roller 5 is arranged.
  • This water jet cutter consists essentially of a nozzle 2, which is arranged above the fibrous web 1 is and directs the water jet approximately perpendicular to the fibrous web 1. to The fibrous web 1 is supported on the opposite side Support plate 3.
  • This support plate 3 has a flat and smooth surface and is in unloaded state about 0.5 mm from the fibrous web 1. During the Cutting, however, the fibrous web 1 is pressed against the support plate 3.
  • the support plate 3 according to FIG. 2 has a recess 12 for the water jet.
  • the support plate 3 also includes a guide part 10, which the forwarding of the severed edge strip into the pulper 6 Dryer section supported.
  • the support plate 3 extends parallel to the run of the fibrous web 1, it offers no possibility of attaching fibers and other dirt.
  • the separated strip 7 is in the under Water jet cutting device arranged pulper 6 out of the dryer section.
  • the collected fibrous web remnants can thus be recycled become.
  • a compressed air or water nozzle 9 blows Strip 7 in the direction of pulper 6.
  • Adhesive to drying cylinder 4 Remains of fibrous web are also removed by a scraper 13 from the drying cylinder 4 away.
  • the fibrous web 1 After the water jet cutting device, the fibrous web 1 reaches one other area of the paper machine, for example for painting or smoothing the Fibrous web 1.
  • the water jet cutting device is very simple and saves because of the without a suction device Considering the continuous operation a lot of energy.
