Abstract
For use as a wood intermediary and the like in industry, an essentially wedge-shaped wood flake with opposite concave and convex surfaces that converge at an imaginary tip outside the flake dimensions. The tip is located beyond the flake a distance of typically between 40% and 100% of the flake length.
Claims21
An essentially wedge-shaped wood flake having a first, concave surface and a second, convex surface delimiting between them said flake, said first and second surfaces converging in an imaginary tip outside said flake, said flake having a center line extending between said first and second surfaces and comprising a first center line section of a first length extending inside said flake and a second center line section of a second length extending outside said flake, said tip being located on said center line, and outside said flake at a terminal end of said second center line section, wherein said second length is between 40% and 100% of said first length.
A method of producing an essentially wedge-shaped wood flake from a log by chipping, said flake comprising a first, concave surface and a second, convex surface delimiting between them said flake, said first and second surfaces converging in an imaginary tip within a converging area, said flake having a center line extending between said first and second surfaces and comprising a first center line section of a first length extending inside said flake and a second center line section of a second length extending outside said flake, said tip being located on said center line, and outside said flake at a terminal end of said second center line section, the method comprising the steps of:
- a) removing wood from said log in said converging area and;
- b) chipping said flake from said log by means of a rotating chipping tool, wherein said chipping tool is guided to extend so far into said removed converging area that said second length is between 40% and 100% of said first length.
A method of profiling a log, comprising the steps of:
- a) generating a saw cut along said log for generating a groove therein;
- b) guiding a rotating chipping tool along said groove for chipping from said log longitudinally extending corners having first and second side surfaces, said chipping tool having a cutting radius extending into said groove and running free therein, said second side surface extending along said saw cut, flakes being produced during said chipping comprising a first, concave surface and a second, convex surface delimiting between them said flake being essentially wedge-shaped, said first and second surfaces converging in an imaginary tip, said flake having a center line extending between said first and second surfaces and comprising a first center line section of a first length extending inside said flake and a second center line section of a second length extending outside said flake, said tip being located on said center line, and outside said flake at a terminal end of said second center line section, wherein said chipping tool is guided along said groove such as to extend so far into said groove that said second length is between 40% and 100% of said first length;
- and
- c) sawing off side planks from said log, said side planks having a narrow surface configurated by one of said side surfaces.
An apparatus for producing an essentially wedge-shaped wood flake from a log by chipping, said flake comprising a first, concave surface and a second, convex surface delimiting between them said flake, said first and second surfaces converging in an imaginary tip within a converging area, said flake having a center line extending between said first and second surfaces and comprising a first center line section of a first length extending inside said flake and a second center line section of a second length extending outside said flake, said tip being located on said center line, and outside said flake at a terminal end of said second center line section, the apparatus comprising:
- a) means for removing wood from said log in said converging area;
- and
- b) means for chipping said flake from said log by means of a rotating chipping tool, wherein said chipping tool is guided to extend so far into said removed converging area that said second length is between 40% and 100% of said first length.
An apparatus for profiling a log, comprising:
- a) means for generating a saw cut along said log for generating a groove therein;
- b) means for guiding a rotating chipping tool along said groove for chipping from said log longitudinally extending corners having first and second side surfaces, said chipping tool having a cutting radius extending into said groove and running free therein, said second side surface extending along said saw cut, flakes being produced during said chipping comprising a first, concave surface and a second, convex surface delimiting between them said flake being essentially wedge-shaped, said first and second surfaces converging in an imaginary tip, said flake having a center line extending between said first and second surfaces and comprising a first center line section of a first length extending inside said flake and a second center line section of a second length extending outside said flake, said tip being located on said center line, and outside said flake at a terminal end of said second center line section, wherein said chipping tool is guided along said groove such as to extend so far into said groove that said second length is between 40% and 100% of said first length;
- and
- c) means for sawing off side planks from said log, said side planks having a narrow surface configurated by one of said side surfaces.
