초록 ▼

A method of forming a fibrous web useful for compression molding stiff, board-like structural substrates for panels by thoroughly intermixing a 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. The web is formed by drying wood fibers, spreading them into a mat, covering the mat with the synthetic fibers and thereafter, dispersing the fibers through a dispersion chamber and recollecting and re-spreading them into a web by means of a picker roller, gravity dropping a powdery resinous molding material upon the web, redistributing and intermixing the fibers and the molding material with a second picker roller, applying the scrim and needling the combined scrim and fiber web for mechanically interlocking them.

대표청구항 ▼

A method for forming a compression moldable panel substrate, including the following steps: (a) forming a layer of substantially evenly distributed random oriented natural fibers; (b) covering an upper surface of the layer of natural fibers with a relatively thin layer of generally evenly distributed, randomly oriented synthetic plastic fibers; (c) conveying the layers of natural fibers and plastic fibers to an upper end of an open blending chamber and gravity dropping the fibers into the blending chamber for loosely mixing such fibers together and forming a relatively thick mat of substantially evenly distributed natural fibers and plastic fibers; (d) depositing an uncured, resinous molding powder material upon at least one of the surfaces of the relatively thick mat; (e) re-mixing the fibers and simultaneously mixing and evenly distributing the molding material within the fibrous mass comprising the mat to form the mat into a relatively wide and thick web; (f) rapidly needling the relatively wide and thick web for mechanically interlocking the fibers to each other by the rapid movement of needles transversely through the relatively wide and thick web; and (g) removing the needled web so that it may later be cut to size and to a shape and used in a compression molding process which includes the application of heat and pressure upon the needled web, within a mold to form a relatively stiff, board-like structural substrate for panels.
