Abstract
An apparatus for aligning the ends of lumber pieces on a common register during conveyance of the lumber pieces. A lug type chain conveyor has wheel sets positioned between adjacent chains. The wheel sets have multiple freely rotating idler wheels positioned at an angle to the direction of conveyance of the conveyor. The periphery of the wheels extend above the chains a nominal distance. The lumber pieces, as they are being conveyed on the conveyor, engage the idler wheels of the wheel sets causing the idler wheels to rotate. The rotation of the idler wheels urge the lumber piece to move transverse to the travel direction of the conveyor to position the end of the lumber pieces in abutment with a register at the side of the conveyor.
