Abstract: A method for forming a fiber web and fibrous web useful for compression molding stiff, board-like structural substrates for panels is formed of a thoroughly intermixed blend of wood fibers and synthetic plastic fibers with a dry, powdery, resinous molding material uniformly disbursed throughout the blend. The mass of intermixed fibers and resinous molding material is covered with a thin, randomly oriented, fibrous scrim material and the fibers are locked to each other and to the scrim mechanically by means of needling them together.

Abstract: An improved method for manufacturing a relatively thick, needled, non-woven fiber padding eliminates the conventional step of initially making a laminated blanket of garnet formed, thin, oriented fiber layers. Instead, this method initially forms a thick, single layer blanket of loosely piled, randomly oriented fibers, which blanket is simultaneously compressed and tack needled incremently along its entire length to intertwine and mechanically interlock random portions of the fibers. Thereafter, the conventional needling step is applied to complete the padding.
