Abstract: A hydraulic board-laminating press comprises a series of laterally aligned hydraulic clamps supported in an inclined plane, each clamp having one fixed and one movable clamping jaw defining an upwardly opening mouth for receiving boards. The positions of the fixed jaws are adjustable along the inclined plane for providing camber in the beam produced. A series of infeed conveyor arms spaced along the lower side of the press deliver boards, adhesive-coated on one face, edgewise and one at a time into the mouths of the clamping jaws. An outer section of each conveyor arm can be extended and retracted toward and away from the clamps and can be raised and lowered so that the outer ends of the arms deliver boards into various positions within the space between jaw pairs to stack boards within the jaws along the inclined plane of the clamps.
