Two Graders, facing each other, pull lumber from an adjacent unit and crayon mark defects. After each board is graded, the Grader pushes it onto a table area. Adjustable, impact resistant mirrors are attached to the frame to allow the Grader to view the bottom of the board for defects, eliminating the need to turn/flip the lumber. An idler roll in the far end of each table assists the Grader as he pulls material from the unit. A powered, canted roll conveyor is located between the marking tables. Canted rolls keep marked boards against the fence side of the line for proper positioning thru the camera section. As Graders finish marking, they nudge the board onto the roll section, ensuring an adequate board in the process. A variable speed drive powers the rolls at speeds appropriate to the saw’s processing ability or to match other production requirements.
