Abstract
An apparatus for producing an essentially wedge-shaped wood flake comprises a chipping tool rotating about a first, horizontal axis for chipping the flake out of the wood such that the flake has a first, concave surface and a second, convex surface. The flake is delimited between the surfaces. A circular saw blade is provided rotating about a second, vertical axis for removing wood in an area in which the surfaces intersect in an imaginary tip, prior to the chipping out.
Claims12
An apparatus for producing an essentially wedge-shaped wood flake, comprising:
- a) a chipping tool rotating about a first, horizontal axis for chipping said flake out of said wood such that said flake has a first, concave surface and a second, convex surface, said flake being delimited between said surfaces;
- and
- b) a circular saw blade rotating about a second, vertical axis for removing wood in an area in which said surfaces intersect in an imaginary tip, prior to said chipping out.
An apparatus for profiling a log, comprising:
- a) a chipping tool rotating about a first, horizontal axis for chipping longitudinally extending corners out of said log, said corners having a first and a second lateral surface;
- b) means for cutting off lateral boards from said log, one narrow side of said lateral boards being configured by said first lateral surface;
- c) a circular saw blade rotating about a second, vertical axis for guiding a saw cut along said second lateral surface prior to chipping out said corners, thereby generating a groove;
- wherein said chipping tool has a cutting radius extending into said groove such that said chipping tool runs freely in said groove.
