Definitions

  • the invention relates to a device for application a micro crepe on a paper web according to the Preamble of claim 1.
  • Paper webs treated in this way are often used for bag production used.
  • the aim of the invention is to avoid these disadvantages and propose a device of the type mentioned at the outset with which the manufacture of a high slip resistance and a paper webs with high dust absorption capacity can be.
  • the features of claim 2 give the advantage that the paper web is structured very finely. Practically results a crepe of the paper web in its longitudinal and Transverse direction, making such a paper web a special one maintains high dust absorption capacity. Furthermore, one stands out paper web treated using such a blanket with a particularly high slip resistance.
  • a device for applying a micro crepe has in essentially a heated and driven cylinder 10 and a driven revolving rubber blanket 11 which is driven and Guide rollers 12 runs and by means of a tension roller 13 is subjected to a certain tension.
  • a press bar 14 is provided, which is radial to the cylinder 10, which has a polished surface, is movable.
  • the press beam 14 is in the direction of the rubber blanket 11 Spray tube 16 immediately upstream, with a Wassser-Si-likon mixture is sprayed on the rubber blanket 11 to reduce the friction to reduce between the press bar 14 and the blanket 11.
  • the rubber blanket 11 describes in the area of the press beam a convex curved path to the immediately a concavely curved, abutting the cylinder 10 Track area of the rubber blanket 11 connects.
  • the paper web to be creped runs between the rubber blanket 11 and the cylinder 10 through.
  • the paper web 17 passes between the press point the heated cylinder 10 and the surrounding rubber blanket 11.
  • the rubber blanket 11 is an endless band with a thickness of approx. 5 mm and approximately larger width than the working width of the incoming paper from a particularly hard-wearing Rubber quality manufactured with a hardness of approx. 50 durometers. It is with a continuous reinforcement insert 18th provided to reduce the fabric stretch.
  • the Process could involve the flow of a liquid through a Venturi nozzle are compared.
  • Section 1 is flat and runs at a speed from (v - ⁇ v), i.e. slower than the paper web 17 before touching the rubber blanket 11.
  • Section 2 is deformed by the curvature of the press beam 14, the speed is unchanged on the inside, on the outside Extent, however, already approximately at paper speed v accelerates.
  • the following narrowing accelerates this Cloth 11 outside so that it is at the beginning of section 3 already the speed v of the paper web 17 or the cylinder circumference has reached so that the paper web 17 unimpeded can enter between cloth 11 and cylinder 10 and the squeeze point passes tightly.
  • the squeezed Blanket 11 Immediately after Passing the narrowest point begins the squeezed Blanket 11 to relax, i.e.
