Definitions

  • Wood-based panels as support materials are used in various fields, such as used as floor panels in the form of laminate floors, as insulation panels for indoor and outdoor use or as wall panels.
  • Such material plates are usually made of wood fibers, wood shavings or strands, e.g.
  • HDF High Density HDF
  • the printing techniques mainly used here are gravure printing and digital printing.
  • the gravure printing process is a printing technique in which the elements to be imaged are formed as depressions in a printing form, e.g. in a printing roller, which is colored before printing.
  • Digital printing makes it possible to produce a print image with particularly high quality through a higher resolution and also allows a wider range of applications with high flexibility.
  • the primer should produce a uniform surface; on the other hand, the pigmentation of the primer layer should cover the inherent color of the wood material.
  • the conventional processes have a number of disadvantages.
  • the conventional process for direct printing of fiberboard is highly dependent on climatic conditions. Moreover, this process does not allow any reaction possibilities in the case of short-term investment scenarios on the fiberboard line and there is a reduced or Inferior quality during priming and printing up to increased rejects.
  • the present invention is therefore based on the technical problem of solving the problems described with the least possible technical effort and to be able to further process wood fiber boards under moisture fluctuations.
  • an increase in costs should be avoided and, if possible, the costs should be reduced.
  • a process is provided with the present method, in which a targeted moistening (steaming or spraying) with water-containing steam, preferably water, is carried out by not yet re-climate-treated wood fiber support plates.
  • a targeted moistening steaming or spraying
  • water-containing steam preferably water
  • the method after separating the wood fiber support plates, eg from a stack of plates, either part / section or the entire surface of the wood fiber support plate is increased by steaming or spraying with water-containing steam in the wet level in front of the printing line. Since the primary objective of the present method is to moisten the surface of the wood fiber support plate, just a few grams of water-containing steam per square meter surface suffice. By limiting the moistening or evaporation amount is also avoided that it comes in the surface of the wood fiber support plates to eventual fiber swelling, which could cause an impairment of the surface or surface unrest.
  • the present method provides significant benefits in terms of cost reduction, inventory reduction, and quality improvement
  • a first grinding machine will be positioned so that slight swelling can be removed immediately if necessary.
  • the humidification can be adjusted depending on the existing problem or problem by failure of a corresponding program.
  • an aqueous liquid on wood fibers during the production process of wood fiber boards is eg from the DE 10 2008 008 240 B4 or even the DE 10 2008 049 132 A1 known, with significant differences to the present method.
