Definitions

  • the invention relates to a process according to the preamble of claim 1 for producing a wood composite product, preferably a longitudinal wood composite product, consisting of a first board and a second board.
  • the invention also relates to a wood composite product according to the preamble of claim 19, preferably a longitudinal wood composite product, comprising a first board and a second board.
  • a board is henceforth referred to a board, a longitudinal piece of wood or the equivalent.
  • a wood composite product is henceforth especially, but not exclusively, referred to other equivalent wood composite products, a stud or a joist.
  • round logs have been sawn into studs or joists in such a way that the round log is first sawn in the longitudinal direction of the round log in order to first obtain studs or joists with the desired thickness and in which at least one side edge is a wane edge. Thereafter the wane edge or wane edges have been sawn away in order to obtain the desired breadth of the stud or the joists.
  • the wood composite product in according to the invention is characterised by that which is presented in independent claim 19.
  • the invention is based upon that the side edges of the boards, which are linked together as the boards are jointed into a composite product, are wane edges, which are machined in such a way that they can be jointed.
  • a board of this kind has a rounded side edge or two rounded side edges
  • a board of this kind has a first face (an upper or under face) on one side of the board, which has a larger area than the other face (the upper or under face) of the board on the opposite side of the board.
  • a wood composite product may be obtained, the breath of which exceeds the breath obtained by first sawing the wane edges off both boards so that, in both boards, a side edge is obtained, which is orthogonal in relation to the flat upper and under face of the board, and by then jointing the straight side edges of the boards together.
  • the bent wane edge in a first board, which shall be jointed to a second board is machined to a first side edge, showing a first longitudinal contact surface and a first longitudinal bevelled side edge fraction.
  • the bent wane edge in a second board, which shall be linked to the first board, is machined to a second side edge, showing a second longitudinal contact surface for interaction with the first longitudinal contact surface of the first board and a second longitudinal bevelled side edge fraction for interaction with the first longitudinal side edge fraction of the first board.
  • a longitudinal bevelled side edge fraction is formed in the side edge of the boards, the side edges of the boards get an at least partially askew cross section.
  • the askew cross section results in that the preferred embodiment, which the board originally had before machining of the side edge, can be substantially preserved.
  • this preferred embodiment design is meant that the board because of the bent wane edge originally had an under face, which had a larger area than its upper face or vice-versa. I the same way, the board, the side edge of which has been machined, has an under face, which had a larger area than its upper face or vice-versa.
  • the boards are laid out alongside so that the bigger face of the first board is evenly parallel to the smaller face of the second board and in such a way that the smaller face of the first board becomes evenly parallel to the bigger face of the second board and in such a way that the interacting bevelled side edge fractions and the interacting longitudinal contact surfaces in the first and the second board are turned to face each other.
  • first side edge of the first board and the third side edge of the second board are connected in such a way that the first even face of the first board and the fourth even face of the second board together form a first even surface, which is substantially parallel to the second even surface, which is formed- by the second even face of the first board and the third even face of the second board together, and the first side edge of the first board and the third side edge of the second board are glued together in such a way that the first board and the second board form a substantially monolithic entity.
  • bent wane edges are in the invention machined into side edges with a longitudinal contact surface and a longitudinal bevelled side edge fraction, i.e. into side edges, which at least partially have an incline in relation to the even upper and under face of the board, in the invention less of the area of the face of the first board and the face of the second board is lost, which has the larger area, and at the same time less of the cross section area of the first board and the second board in comparison to if the wane edge of the first and the second board would, for instance, be sawn straight off in order to get a side edge in the first and the second board, which is orthogonal in relation to the even upper and under face of the board.
  • first board and the second board are jointed together in such a way that the first even face of the first board and the fourth even face of the second board together form a first even surface, which is substantially parallel to the second even surface, which the second even face of the first board and the third even face of the second board form together, this accomplishes that the bending of the wood composite product at least partially is counteracted, since the bending of the first board counteracts the bending of the second board and vice-versa.
  • the face of the first board, which originally before sawing the round log was situated closer to the core or heartwood of the round log on the same side as the face of the second board, which originally before sawing the round log was farther away from the core or heartwood of the round log and since a board bends around the original core or heartwood
  • bending of the wood composite product can at least partially be counteracted by the invention, since the first board bends at least partially counter-clockwise around its original heartwood and since the second board bends at least partially clockwise around its original heartwood or vice-versa. The bending may be even further reduced, if the wood composite product is manufactured of boards, sawn from different trees.
  • the first longitudinal contact surface of the first side edge of the first board shows a first tongue and a first groove
  • the second longitudinal contact surface of the third side edge of the second board shows a second tongue for interacting with the first groove of the first longitudinal contact surface and a second groove for interacting with the first tongue of the first longitudinal contact surface.

  • first longitudinal contact surface in the first side edge in the first board shows a first tongue and a second tongue
  • second longitudinal contact surface in the third side edge of the second board show a first groove, which together with the first tongue of the first longitudinal contact surface forms a formatting joint
  • a second groove which together with the second tongue of the first longitudinal contact surface forms a formatting joint

  • the first board and the second board in this preferred embodiment have been turned in relation to each other in such a way that the first longitudinal bevelled side edge fraction of the first board lies alongside the second longitudinal bevelled side edge fraction of the second board. Since the first side edge of the first board and the third side edge of the second board are substantially of the same dimensions and substantially the same form, the wane edge of the first board and the wane edge of the second board can be machined with the same cutting tool so that the first side edge of the first board and the third side edge of the second board are substantially of the same dimensions and substantially of the same form.
  • the invention also enables that cuneiform boards, i.e. boards with a cross section, which is larger in one end of the board than in the opposite end of the board, are jointed into a wood composite product with a uniform cross section along the entire wood composite product.
  • a uniform cross section can also be achieved by machining the wood composite product after the jointing.

Abstract

La présente invention concerne un procédé destiné à fabriquer un produit composite en bois comprenant une première et une seconde planche (1, 2). On prend une première planche (1), sciée à partir d'une bille de bois (8) de telle sorte que le premier bord latéral (6) correspond à une flache (9) et que la première face lisse (4) possède une surface supérieure à celle de la deuxième surface lisse (5), et on prend une seconde planche (2), sciée à partir d'une bille de bois (8) de telle sorte que le troisième bord latéral (14) correspond à une flache (9) et que la troisième surface lisse (12) présente une surface supérieure à celle de la quatrième face lisse (13). On usine le premier bord latéral (6) afin d'obtenir un premier fragment de bord latéral oblique longitudinal (11) et on machine le troisième bord latéral (14) afin d'obtenir un second fragment de bord latéral oblique longitudinal (17) destiné à interagir avec le premier fragment de bord oblique latéral (11). L'invention se rapporte également à un produit composite en bois.
