Abstract
A method and apparatus for peeling a tapered block by setting the cutting edge of the peeling knife on an angle comensurate with the taper of the block. In one embodiment, the angle remains substantially constant throughout the peeling operation so that the resulting core is tapered. In another embodiment, the angle continuously changes and the veneer is cut thicker at one side than at the other whereby to produce a tapered veneer and result in a substantially right cylindrical core when the peeling operation is completed.
Claims9
A method of peeling veneer from a tapered wood block having a larger diameter end and a smaller diameter end comprising sensing the shape of said block, mounting said block to rotate about a rotational axis in a veneer lathe for peeling by a cutting edge to form a veneer, independently moving one axial end of said cutting edge relative to the other in accordance with said sensed shape to adjust said cutting edge to a cutting angle that it is not parallel to said axis of rotation at the commencement of said peeling to produce veneer with the axial end of said cutting edge adjacent the larger diameter end of said block spaced farther from said axis of rotation of said block then the opposite end of said cutting edge.
