Definitions

  • the invention relates to a method according to the preamble of patent claim 1.
  • this disadvantage is intended to be substantially limited, which is achieved in that the roller core receives a higher temperature than the plastic sheath applied to it.
  • the roller can be heated directly by a flowing heat transfer medium or by heating rods or windings. Indirect measures or means for increasing the temperature of the metal roller core can also be used.
  • the measure according to the invention prevents the water from penetrating too strongly from the surface of the roll shell and from the coating composition into the roll shell in the direction of the roll core. Of course, this is otherwise very slow, but still too fast for an acceptable service life of the roller during its operational use.
  • the surface temperature of the roller core is slightly higher than the surface temperature of the roller shell, in each case radially on the outside. In general, no temperature difference greater than 50 K will be used.
  • Heated rolls are known in a wide variety of designs, but they are purely metal rolls, from which a high surface temperature is required, for example for the predominant use in calenders.
  • a thin layer of high thermal conductivity is arranged on the inside of the solid, thick roll casing in order to uniformly heat the roll casing.
  • the inner layer is made of copper, about 5 mm thick, and the casing is made of chilled cast iron (steel).
  • the problem to be solved there was to avoid a filling liquid of the inside of the roll with the corresponding inertia of the heat transfer during the heating and cooling of the roll.
  • roller according to DE-A-37 41 232 with a rubber jacket on a metal core is heated from the inside solely for the purpose of applying a color which is hotly released from a carrier tape to a carrier, in particular as a lettering or number. Neither water nor other moisture or solvents occur here. It is also only a very small roller about 15 cm in length, which is cheap and can be replaced more often without great expense.
  • the roll core with 1 and the roll shell with 2 the roll core is a hollow cylinder made of metal, preferably steel.
  • This hollow cylinder is closed at the end and has stub shafts 3 and 4, which also have a central through bore 5. This results in natural channels for the supply and discharge of heating fluid or heating gas.
  • the temperature of the roller core has to be kept only a few degrees above the ambient temperature or the temperature of the coating compound, if it is heated and thus also heats the roller jacket.
  • the coating is not heated above the ambient temperature. So heating the roller to about 30 to 50 ° C is sufficient. A natural temperature gradient is then established from the roll core to the surface of the roll shell.
  • a temperature difference between the surface of the jacket and the surface of the roll core of 0.1 K is sufficient, a range between 1 and 20 K is preferred.
  • Another possibility would of course be to provide heating rods or heating coils on the inner surface of the hollow cylindrical roller core.
  • the electrical heating power would then have to be transmitted to a stub shaft via slip rings.
  • FIG. 2 A further possibility is shown in FIG. 2, where eddy currents are generated in the same by inductive coupling of an electromagnet and the roller core, which eddy heating of the core.
  • the electromagnet is there from an iron core 8 with at least one winding 9.
  • heating rods 6 and heating windings 7 are also indicated in slots 10 of the roller core.
  • the process according to the invention can be advantageously carried out in a coating device with two press rolls according to US-A-48 48 268 or in a feed device for coating material with at least one counter roll guiding the paper or cardboard web over a certain wrap angle, e.g. according to US-A-42 50 211 can be used.
