Definitions

  • the invention relates to making an edge surface of a wood fibreboard suitable for the application of paint.
  • MDFB medium density fibre board
  • HDFB high density fibre board
  • German published patent application 1,290,849 states the polishing of a surface to be treated with artificial resins and a solvent, on certain conditions as to the concentration of the solvent.
  • the Australian patent specification AU-B-549776 describes a treatment which causes a sealant to penetrate into the pores by means of a heated ironing member.
  • DE-B-1,180,122 states a treatment at which, under pressure, a liquid thermoplastic is brought into the pores of wood fibreboards.
  • German patent specification 906,189 proposes an application of a protein containing solution.
  • the invention offers a solution to the last-mentioned disadvantages by providing that the pores in the edge surface are sealed by moving the edge surface along a heated ironing surface while pressing the ironing surface against the edge surface.
  • the ironing surface is preferably heated to 250-350°C. It has been found that, in doing so, discolouration as a result of burning can be completely prevented and that, moreover, a smooth surface is obtained which, as experience has shown, forms a well adhesive sub stratum for common paints and varnishes.
  • the hold-down pressure is preferably 2-25 kg/cm2. This hold-down pressure is not entirely fixed, because a resilient mounting of hold-down members and ironing members is preferably avoided. Such a resilient mounting does give a well defined hold-down force but its disadvantage is that the members must be withdrawn whenever a new object to be treated is brought in.
  • a further elaboration of the invention provides that a profile cut out off a fibre board, which has at least one edge surface reaching from the one main surface of the fibreboard to the other, is propelled in its longitudinal direction between a hold-down member and the ironing member by means of driven rollers.
  • edge surface has a flat surface and, adjacent to it and close to one of the main surfaces, a curved part and when the ironing surface has a complementary shape, while the profile is moved to the ironing surface by a hold-down member located opposite the flat surface and by one located opposite the curved surface.
  • a hold-down member also has an ironing surface, for example when a profile with two edge surfaces located opposite each other has to be treated.
  • the invention also comprises a device suitable for the application of the method and a profile obtained by applying the method.
  • an ironing member is indicated with 1, which is set up alongside a track with a bearing surface 4 which has freely rotating rollers 7 underneath that rise a little above the top of the surface 4.
  • On the top driven rollers 5 are applied, which can be pressed against a profile to be treated 3 by means of parts not drawn.
  • ironing members located opposite each other 1 and 2, which also serve for each other as hold-down members.
  • These ironing members have a flat surface 8 and beneath it a small arc 9.
  • the surfaces 8 can be positioned vertical as well as somewhat inclined.
  • the hold-down members 6 are used for pressing the profile 3 down against the curved part 9 of the ironing members 1 and 2.
