Definitions

  • the invention relates to a method or a device for treating surfaces.
  • Wood materials are not in their original form Leave appearance, but get one finishing surface coating. Usually acts it is a melamine coating. Veneers, decorative laminates or decorative films are also used as coating material.
  • edge banding The coating of side surfaces, edges or generally from narrow areas is often done by a special edge material.
  • a special edge material For example it is a edge band or a so-called Narrow area belt, which by means of a Glue is applied to the narrow surfaces. This process is commonly called edge banding designated.
  • One way to do a surface coating consists of the coating material as edge material to use the top and bottom.
  • the coating material on the top or bottom of a applied to the plate material to be coated This is preferably done using a dispersion adhesive.
  • Edge usually has sufficient material protrusion, the appropriate way, usually through the addition of heat.
  • the surfaces to be coated have often large bumps, blowholes, etc. on. This applies in particular to chipboard.
  • Such a surface condition leads to coating with one of the specified methods to a strikingly restless, "humped", wavy material surface that has the look, for example of the later piece of furniture.
  • the material thickness is also an increase the restoring force of the bent coating material connected. This in turn requires an extended one Pressure path for gluing such stiffer coating material.
  • thicker coating materials in usually more expensive.
  • GB-A-745 057 also describes a method for the treatment of Surfaces known, being a thermoplastic Coating material is applied to the surface and that applied coating material by means of a Surface of the band passing by is then smoothed.
  • the object of the present invention is therefore in being a process, respectively Specify device with or with which eliminates the aforementioned drawbacks and a surface smoothing treatment is possible in a simple manner.
  • the coating material is by means of a transfer belt applied to the surface.
  • This has the advantage that for the Order of the material does not match the profile of the Coating roller adapted to the coating surface necessary is.

  • the application of the coating material is preferred on the surface to be treated Press force accomplished.
  • a suitable printing device acts on the tape on the uncoated Side with a force that pushes the coated transfer belt side to the coating surface causes.
  • An improvement in the material order is made through additional heat treatment of the coating material achieved.
  • the coating material immediately before the order on the surface to be coated onto the transfer belt upset.
  • the order is preferably placed via an appropriate applicator roller or Application nozzle that the material to be set in a Material thickness brings on the transfer belt.
  • the material to be set in a Material thickness brings on the transfer belt.
  • the transfer belt is removed from the patient to be treated Surface peeled off, taking the material beforehand penetrated into the pores of the surface to be treated and is solidified, so that this when pulling off of the transfer ribbon does not stick to it.
  • the removed transfer belt back to the application roller returned so that the use of a Endless belt is possible.

  • the transport speed of the Transfer bands of the transport speed of the Chipboard 1 corresponds to the drive speed the further role 15 depending on the waked Diameter set.
  • the control mechanism for the further roller 15 can omitted if instead of the unwound from the roll 13 Conveyor belt an endless transfer belt 11, which is shown in broken lines in the figure is used. Instead of the two rollers 13 and 15 are different pulleys in this case 17 necessary after the transfer belt 11 Pass through pressure zone 7 back to the beginning to lead.
  • the endless transfer belt 11 is used by the coating plates 1 with drawn; it can also a separate drive can be provided.

Good flowability of the material is important in that it does that Transfer belt can wet better, better on the narrow surface 3 to be coated can be applied and moreover better in the pores of the particle board can penetrate. Too much penetration too is avoided, the one facing away from the narrow side Side of the coating or the conveyor belt cooled, for example by means of a Cold air shower or a cooling roller.
