Definitions

  • the invention relates to a method for repairing knotholes in lumber, in particular boards, in which a hole is drilled in the lumber in the area of the knothole and a cylindrical dowel is inserted into the hole.
  • the invention relates to a device for performing the method with a drilling machine, one with drilling spindle and drill and a support frame for the drilling machine with a holder and a support part.
  • the invention also relates to a dowel.
  • knotholes drilled according to the known prior art and the washers used are circular in all cases, which disrupts the grain of the board and gives the surface structure of the board an artificial character.
  • the object of the invention is to provide a method of the type mentioned, in which on the one hand a very natural appearance of the board is achieved when inserting the dowels and on the other hand only very small holes have to be drilled so that the grain of the board adjacent to the knothole is not or is only slightly disturbed.
  • the device according to the invention is characterized in that the drilling machine is held obliquely in the holder with respect to the workpiece surface and in that the support part comprises at least one vacuum or vacuum suction foot.
  • the dowel according to the invention is characterized in that the flat end face is oriented obliquely with respect to the dowel body.
  • the dowel preferably has two oblique end faces which are parallel to one another.
  • the hole is drilled at an angle of approximately 35 ° to the surface of the sawn timber, for example boards.
  • FIG. 1 shows a diagram of a section of a board
  • 2 shows a dowel according to the invention
  • 3 shows a cross section through a board with holes according to the invention
  • FIG. 4 shows a board with the device according to the invention in the diagram.
  • the board 1 has notch-like knotholes 2. These notch-like knotholes can be drilled out with the device 3 according to the invention according to FIG. 4.
  • the drilling machine 4 is supported in a support frame 5 which has a support part 6 and a holder 7.
  • the support part 6 can be placed directly on the board 1 when carrying out the method, ie when drilling the knotholes, and it has at least one squeegee 8 by means of which it can be firmly anchored on the board 1.
  • the suction base 8 is connected via a line 9 to a preferably continuously operating vacuum pump.
  • This type of attachment enables the support frame 5 to be anchored quickly on the board 1 and is also suitable for absorbing the oblique forces that occur.
  • the drill 4 is held at an angle by the bracket 7, which is inclined with respect to the support part 6, and the combined drilling and milling tool 10 is at an angle of 35 ° to the surface of the board 1.
  • Blind holes 11 are preferably drilled into the board 1.
  • through-holes 12 can also be drilled, particularly in the case of very thin boards.
  • the dowels 13 are inserted into the drilled oblique bores 11, 12.
  • the dowels 13 have a cylindrical dowel body 14 and a flat but oblique and therefore elliptical end face 15.
  • the retention of the dowels 13 in the bores 11, 12 can, if desired, be improved by an adhesive.
  • the bores 11, 12 for drilling out the knotholes can be kept very small and a very natural-looking board surface is achieved.
