Definitions

  • the invention relates to a method for applying glue to an endless web, especially on wave tips of a corrugated side of an endless web in the Corrugated cardboard production and one suitable for carrying out the process Gluing unit.
  • gluing units for corrugated cardboard systems such as those from DE 39 24 273 C2 are known
  • the wave crests or wave peaks are glued a corrugated side of a material web, for example a one-sided Corrugated cardboard in such a way that by means of a metering roller and a glue application roller an exactly defined gap is formed, on one side of which in a Glue tub located glue is provided.
  • the metering roller and the glue application roller are driven in opposite directions so that a layer of glue on the surface of the glue application roller after the gap predetermined thickness arises.
  • the material web to be glued is in contact with brought to the glue-coated surface of the glue application roller.
  • Such known gluing units have the disadvantage that the gap between Metering roller and glue application roller must be adhered to with high precision. This requires extremely precise in terms of eccentricity and concentricity Training of the rollers. Especially when using glue with high The solids content must be the one to be set between the metering roller and the glue application roller Gap to very small values on the order of a few tenths Millimeters can be reduced. This gap width must also be the highest Precision, for example with a tolerance of ⁇ 0.02 mm.
  • the invention is therefore based on the object of a method for applying Glue on the shaft tips of a corrugated side of a material web for production of corrugated cardboard, as well as a suitable gluing unit, whereby less Glue layer thicknesses are achievable or smaller amounts of glue to the glue to be glued Continuous web can be applied.
  • the gluing unit should be simple be built and inexpensive to manufacture.
  • the invention is based on the knowledge that the requirements for a reduced thickness of the glue layer on the glue application roller or after a smaller one amount of glue applied to the paper web to be glued with the conventional system consisting of metering roller and glue application roller hardly more can be taken into account since the manufacturing tolerances for the rollers for glue plants currently in use so low and the demands on the accuracy of the storage and the drive of the rollers are already so high that the feasibility limit seems to have been reached.

  • the passage of the glue can either by the dynamic pressure and / or static Pressure of the glue in the glue pan against the surface of the endless sieve or by "artificially creating" pressure in the glue pan, for example be made possible by means of a controllable pump. In the latter case the glue unit must of course face the surface of the endless screen be essentially sealed.
