ABSTRACT:
An edging apparatus edges a wood board to achieve a desired rounding effect under a rounding rule of the lumber industry. A positioning apparatus positions and holds two edging saws, and the positions of the saws are initially controlled by an operator who selects initial cut positions. Input data, including board length and thickness parameters and the initial cut positions are generated by input devices and a computer is responsive to the input data for computing the best cut positions of the saws. In making this computation, the computer takes into consideration the rounding rule and, according to predetermined criteria, the computer selects best cut positions that will produce an edged board whose measurement exceeds a whole board foot measurement by a desired fraction of a board foot. Adjustment input may be provided to adjust the size of the desired fraction of the board foot. The computed best cut positions are then transmitted as output from the computer so that the saws may be positioned in accordance therewith. Length trim markers are positioned in front of the saws to mark the trim length of the board before it is edged. Thus, length trim and edging decisions may be made at the same time by the same operator before edging or trimming the board. In one form, the thickness of all boards is assumed to be one inch, as is the custom of the industry.
