Abstract
A method of making panels of composite wood material in a wet process includes depositing a layer of wet composite wood material in a mat on a press wire screen mesh and moving the screen mesh to carry the mat into a pressing position between a pair of spaced apart pressure plates having generally matching, contoured facing surfaces for shaping the outer face and a smoothly contoured back face of the panel. The pressure plates are moved toward one another compressing the mat of wet material and biasing the supporting screen mesh to conform generally to the contour of one of the pressure plates. After a suitable time interval for molding, the pressure plates are moved apart and the press wire screen mesh is rewound on a roll to aid in separating the completed panel from the mesh. The finished panel is carried by the screen mesh away from the pressure plates for unloading as the screen is rolled up and the deformations formed in the screen during molding are flattened out as the screen is rewound on the roll.
