Definitions

  • the invention relates to a stationary slide bar for guiding a running fibrous web, in particular a paper or Board web.
  • a rolling machine is known from D3, FR-A-2 522 631, in which the web of a roll of a slitting device is fed.
  • the web is over guided a fixed guide table.
  • the guide table is towards the web side convexly curved, whereby air flows into the gusset between the web the curved table and the web is brought in and thereby the web floating in an air film.
  • From DE-A-3 423 539 (D4) is a device for adjustment and maintenance the tension in the transverse direction of a web, in particular a paper web, is detectable.
  • This device has several loading units in the transverse direction of the web available. The loading units can be moved towards the web and with one curved guide surface.
  • a paper coating device is disclosed in DE-A-4 415 581 (D5), in which as a means a rotating, driven roller is provided for web deflection.
  • the diameter the roller must be large enough to be able to move at high web speed Air cushion forms and remains above the deflection roller, so that the running web floats and the freshly applied coating medium is not damaged.
  • the present invention has for its object a stationary slide rail for guiding a paper or cardboard web to be designed in such a way that it is as easy as possible producible and generally usable without active air supply is.
  • the invention Compared to conventional guide rolls, the invention has stationary slide bar a lighter weight and none movable elements (no rotating mass); therefore only a simplified chair is required.
  • An additional one important advantage is that the invention Slide bar insensitive to high temperature and to Temperature fluctuations.
  • Figure 1 shows a section of a Coating line for a paper or cardboard web with associated Drying device.
  • Figure 2 is one schematic oblique view of a stationary slide bar.
  • the Figure 3 shows a complete off-line coating machine.
  • FIG. 4 shows a partial view (in the direction of arrow IV of FIG Figure 3) on the track with a curved slide bar.
  • FIG. 5 shows an archable over its length and also tiltable slide bar.
  • FIG. 6 is a cross section along line VI of FIG. 5.
  • a paper or cardboard web 7 runs over web guide rollers 5 in a coating unit 8, from there via further web guide rollers 6 to a drying unit 9.
  • Part of the web guide rollers 5, 6 and the am Web guide roller 12 arranged at the end of the drying unit 9 are provided with only symbolically represented drives.
  • the individual stationary slide bar 10 supported several holders or on a support bar 14.
  • the Support bar 14 and the slide bar 10 fastened thereon across the entire width B of the web 7.
  • Die Slide bar 10 has a convexly rounded (seen in cross section) Surface 11.
  • the slide bar 10 made from a simple, cheap steel.
  • the convex rounded surface 11 is provided with a coating, for example made of a hard metal or ceramic. If required, the coated surface 11 becomes smooth polished. In this way, the surface 11 is insensitive against occasional contact with the running web 7. However is with continuous operation of the plant with a relatively high Web running speed a contact of the web 7 with the surface 11 of the slide strips 10 avoided in that the bottom transported an air boundary layer to the train, so that there is an aerodynamic on the inlet side of each slide bar 10 Grease wedge forms.
  • the arrangement according to Figure 1 is such that in the Coating system 8 and coated the top of the paper web then dried by the drying unit 9, so that only the uncoated underside of the web with the web guide rollers 6, 12 and occasionally or temporarily with the slide bars 10 comes into contact.
  • a slide bar but can also be arranged on the painted side of the web, z. B. if the line thickness is relatively small.
  • the underside of the impact jet dryer is 9 just. Therefore, the slide strips 10 are arranged such that the web 7 on a substantially straight line runs along the bottom of the dryer 9. The web 7 will therefore not deflected (or not significantly) at the slide rails.
  • the slide bar according to the invention is also for others Suitable applications where they have to run the web more or less redirect.
  • this shows a complete off-line coating machine, those for coating relatively thin papers is suitable at very high working speeds.
  • several stationary slide rails according to the invention in Positions arranged where previously normal rotatable Guide rollers were arranged.
  • One recognizes in detail in 3 shows a unwind station 20, from which the paper web 17th runs to a coating unit 18 for the web top and then past infrared dryers 21, through hot air dryers 22 and through a drying cylinder group 23.
  • the web 17 then runs through a second coating unit 18 for the underside of the web, also passing infrared dryers 21, by hot air dryer 22 and by a second Drying cylinder group 23, after which the finished coated web is wound up in a rolling apparatus 24.
  • a second coating unit 18 for the underside of the web, also passing infrared dryers 21, by hot air dryer 22 and by a second Drying cylinder group 23, after which the finished coated web is wound up in a rolling apparatus 24.
  • the path deflection at each of the stationary Slide strips 10 approximately between 5 degrees and a maximum of approximately 40 Degree. But you can also provide a larger deflection, for. B. in the order of 90 °.
  • Figure 4 is indicated schematically that a slide bar 10A bent approximately parallel to the direction of web travel can be. This allows the paper web 17 to be transverse to the direction of web travel pull smooth or "stretch". With the help of Bending devices, not shown, can the extent b of Deflection can be varied.
  • FIGS. 5 and 6 show a slide bar 10B, which are in a direction substantially perpendicular to the paper web 18 bent or (in other words) arched can.
  • the width of the paper web is designated by B in FIG.
  • the equal strip 10B (and if necessary a support bar 14A) connected to it rests on several Lifting devices, e.g. Threaded spindles 31. These are about the Length of the slide bar evenly distributed and individual adjustable.
  • the threaded spindles 31 are on a carrier 34 (e.g. square tube).
  • a carrier 34 e.g. square tube.
  • 5 is an example an upwardly curved state of the slide bar designated 10C.
  • the carrier 34 extending parallel to the slide bar has in the illustrated embodiment, one at each end Swivel pin 35, with the help of which it is held in holders 33 (with each a clamping piece 33a) rests.
  • the holders 33 are for example attached to machine side members 36, which on stands 37 rest.
  • the spindles 31 extend in the essentially perpendicular to the paper web 17.
  • the carrier 34 together with the slide bar 10B by a certain angle + a or -a pivot.
  • the angle a can e.g. up to 10 °.
