Definitions

  • the invention relates to a roller according to the preamble of claim 1.
  • rollers are widely used where paper or cardboard is coated in a press nip formed between two rollers.
  • a small application quantity (specific weight per unit area) is generally applied.
  • the coating compositions usually have significant amounts of water as a solvent.
  • the measure according to the invention prevents namely that the water penetrates from the surface of the roller shell and from the coating composition into the roller shell in the direction of the roller core to an excessive extent. 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 rollers are known in a wide variety of designs, but they are purely metal rollers, which require a high surface temperature, e.g. for the predominant application in calenders.
  • roller according to DE 37 41 232 A1 with a rubber jacket on a metal core is heated from the inside solely for the purpose of applying a color which is hotly detached 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 just 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 roll core only has to be kept a very few degrees above the ambient temperature or the temperature of the coating slip if it is heated and thus also heats the roll shell.
  • 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 roll 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 roller can inexpensively in a coating device with two press rollers according to US 48 48 268 or with at least one the web, e.g. especially paper or cardboard web, over a certain wrap angle counter roll of a feed device for coating, e.g. according to US 42 50 211 can be used.
