Abstract
A lumber handling method identifies the existence and direction of crowning in dimensional lumber and automatically orients the board and specifies a cutting direction prior to a saw cutting the board into one or more board segments to be used in a structural board assembly, such as in a truss or a wall panel. Crowning is a curve that occurs along a narrow convex edge of a board, wherein the curve is about an axis that is perpendicular to the board's widest face. In some examples, a board's crown is detected by a row of photoelectric sensors. In some examples, the method involves calibrating the sensors by passing a straight board past the sensors. In some examples, the convex and/or concave edges of the board are marked.
