Abstract
Sheets of wood are cut from a timber piece along a guide and against a cung blade. A transverse taper of the wood piece is measured as the wood piece is conveyed. In accordance with changes in the measured transverse taper, the guide or the blade is pivoted about an axis extending perpendicular to the blade edge as the wood piece is being conveyed. Also, the longitudinal taper of the wood piece can be measured as the wood piece is conveyed. In accordance with the changes in the measured longitudinal taper, the distance between the blade edge and the wood guide is varied as the wood piece is conveyed.
Claims13
Apparatus for the chipless cutting of wood sheets from a piece of square timber having a longitudinal length and a transverse width, the apparatus comprising:
- a wood guide, including a pressure bar, for supporting a piece of square timber for movement, the wood guide engaging a supported side of the timber piece;
- a feeding device for conveying the timber piece along the wood guide in a path of travel;
- a cutter blade having a cutting edge for cutting a wood sheet from the supported side of the timber piece, the cutting edge extending transversely of the path of travel and being slanted at an oblique angle with respect to the path of travel as viewed in a direction perpendicular to the supported side of the timber piece;
- a measuring mechanism arranged to measure a transverse taper of the timber piece by measuring the thickness of the timber piece at least at two transversely spaced locations thereon during conveying of the timber piece;
- and
- an adjusting mechanism operably connected to the measuring mechanism for producing a relative pivoting movement between the blade and the wood guide about a pivot axis extending substantially perpendicular to the cutting edge as viewed in a direction perpendicular to the supported side, in accordance with variations in the measured transverse taper of the timber piece.

- a wood guide, including a pressure bar, for supporting a piece of square timber for movement, the wood guide engaging a supported side of the timber piece;
- a feeding device for conveying the timber piece along the wood guide in a path of travel;
- a cutter blade having a cutting edge for cutting a wood sheet from the supported side of the timber piece, the cutting edge extending transversely of the path of travel and being slanted at an oblique angle with respect to the path of travel as viewed in a direction perpendicular to the supported side of the timber, the depth of cut being determined by a spacing between the cutting edge and the pressure bar;
- a measuring mechanism arranged to measure a longitudinal taper of the timber piece by measuring the thickness of the timber piece at least at two longitudinally spaced locations thereon during conveying of the timber piece;
- and
- an adjusting mechanism operably connected to the measuring mechanism for changing the spacing between the cutting edge and pressure bar to vary the cutting depth, in accordance with variations in the measured longitudinal taper of the timber piece.
