• impregnating the first fabric (1) and the second fabric (2) or fibrous paper with an aqueous based adhesive resin and drying them;
• pressing the impregnated first fabric (1) and the impregnated second fabric (2) or fibrous paper together to form a pressed structure (3) comprising the first fabric (1) and the second fabric (2) or fibrous paper;
• adding an adhesive layer on one of the faces of the pressed structure (3) and adding a decorative sheet (7) on the adhesive layer and forming a formed structure in a required shape of the part to be trimmed;
• applying a primer layer to the decorative sheet (7) of the formed structure and drying the primer layer;
• applying at least one layer of varnish onto the primer layer and drying the varnish;
• wherein, the adhesive layer is acrylic, polyurethane, solvent-based epoxy or water-based epoxy;
• the forming is carried out in a press with hot-plate press (6) at temperatures between 100° C. and 120° C., and the thickness of the decorative sheet varies between 0.2 and 0.6 mm.
