Claim:
Method of manufacturing diagonal laminated veneer lumber comprising: providing a rotary-cut veneer sheet ( 1 ) having longitudinal ends (b) to which the wood grain (a) of the veneer sheet ( 1 ) is oriented substantially perpendicularly, clipping said rotary-cut veneer sheet ( 1 ) along lines (c) extending perpendicularly to said longitudinal ends (b) into a plurality of substantially square- or rectangular-shaped veneer sheets ( 1 a ), joining said square- or rectangular-shaped veneer sheets ( 1 a ) successively at the longitudinal ends (b) thereof thereby to from a band of joined veneer ( 1 ′), clipping said band of joined veneer ( 1 ′) along lines (c′) extending diagonally at an angle with respect the lateral sides of said band of joined veneer ( 1 ′) (or the lines (c) of said rotary-cut veneer sheet ( 1 ) into a plurality of substantially parallelogram-shaped veneer sheets ( 1 ′ a ), laying or joining said parallelogram-shaped veneer sheets ( 1 ′ a ), successively with two adjacent sides of any two adjacent parallelogram-shaped veneer sheets ( 1 ′ a ), which sides extend substantially along the wood grain of the veneer, set in abutment with each other thereby to from a plurality of layers of veneer ( 2 ′ a ), and laminating said plurality of layers of veneer ( 2 ′ a ) together such that any two adjacent layers of veneer ( 2 ′ a ) are disposed in said diagonal laminated veneer lumber with the wood grain thereof oriented diagonally in opposite directions at an angle between 30° and 60° with respect to the longitudinal direction of the diagonal laminated veneer lumber.
