Abstract The disclosure is of a method of manufacturing ornamental relief panels or other moulded articles, characterised in that it comprises the steps of coating a surface of a cover sheet (for example a veneer), placed on a support, with an adhesive without water, placing on this surface a first pre-moulding element, filling the latter with particles of wood previously dried and impregnated with adhesive without water, lightly compressing these particles, placing upon the first pre-moulding element a second pre-moulding element, likewise filling the latter with particles of wood lightly compressed in sequence, removing the two pre-moulding elements, placing upon the articles of wood an adhesive-covered surface of a second cover sheet (for example a second veneer), and finally covering the assembly with a definitive mould and subjecting it in a press to regulatable pressure and temperature.
A method of manufacturing molded articles decorated in relief, comprising coating a surface of a cover sheet with adhesive without water, placing on the coated surface of the cover sheet a first mold having a mold cavity having an open top and an open bottom, filling the first mold with particles of wood previously dried and impregnated with adhesive without water, lightly compressing these particles in the first mold, placing upon the first mold a second mold having an open top and an open bottom but having a mold cavity smaller than the mold cavity of the first mold, thereafter filling the second mold with particles of wood previously dried and impregnated with adhesive without water, lightly compressing the particles in the second mold, removing the first and second molds, placing on the particles of wood an adhesivecovered surface on a second cover sheet, placing the assembly thus produced in a press having a central decorative relief that bears against the exposed side of said second cover sheet, and subjecting the assembly in said press to heat and pressure thereby to produce an article having the appearance of a sculptured panel.
