  • a coating material such as an edge
  • the application of the coating material to the workpieces is often carried out by means of a suitable hot melt adhesive, which is applied, for example, in the hot, molten state on the edge or the workpiece.
  • a suitable hot melt adhesive which is applied, for example, in the hot, molten state on the edge or the workpiece.
  • it is also possible to heat a pre-coated edge with hot melt by means of a hot air blower and so bring the hot melt adhesive to the desired melting temperature.
  • the joint between the coating material and the workpiece should be made as invisible as possible.
  • the gap between the coating material and the workpiece should be as thin as possible, or a functional layer present at the joint (which may also be part of the coating material or the workpiece) should be as little as possible impaired in appearance.
  • the joint connection should have a sufficient strength so that the coating material securely adheres to the workpiece.
  • the EP 1 800 813 A2 a method and apparatus for coating components using a laser.
  • the invention is based on the finding that the adhesive potential of the adhesive or functional layers used is often not fully utilized.
  • the bandwidth of the activation of the respective Hafaffens or the respective functional layer can be significantly expanded so that you can work with undiminished strength of the joint connection with a thinner adhesive layer or a smaller impairment of the functional layer.
  • the result is thus an improved appearance of a coated workpiece and possibly even increased strength of the joint connection.
  • the inventors have found that the inventive provision of at least two energy generating sections, which are operable with at least one operating parameter different from each other, also results in an improved adaptability of the device according to the invention to changing operating conditions.
  • the device according to the invention makes it easier to switch between different coating materials, adhesives or functional layers and / or workpieces. This aspect is also of considerable importance in view of the ever growing, individual customer requirements.

  • control device is set up to operate at least two laser-generating sections with different laser power and / or laser wavelength.
  • bandwidth of the material activation can be increased, in particular for plastic materials to be activated. This can be explained by the fact that different molecular ranges of the material are addressed by different laser power and laser wavelength, resulting in an improved or broadened activation of the material. This makes a significant contribution to the solution of the underlying task.
  • the two different power generation sections have no common operating parameters at all, but are operated in fundamentally different ways.
