Abstract: Process for variously decorating sections made of plastic materials, composite materials and the like, comprising a step of pre-treatment for the preparation of the surface, a possible step of pre-painting, a possible step of pre-heating, a step of decoration by transfer from a strip-like flexible support unwinding continuously from a first coil through the action of at least a rotating nip roll, suitably shaped, heated and thermostated, and lastly a possible step of sublimation and fixing, to obtain the transfer of the decoration and the polymerization of colors. Apparatus for the formation of the decoration, comprising a first coil from which a flexible support unwinds at least a rotating nip roll, shaped according to the section to be decorated, heated and thermostated, and at least a second coil for the rewinding of the flexible strip, once the decoration layer and the protection layer have been removed.
Abstract: A process for the production of extruded profiles and shaped sheets, variously decorated, especially from aluminium alloy to be used in the building field, for domestic appliances and the like, comprising the steps of preliminary preparation of the surfaces of the article (1), the application of preliminary painting cycles or other surface treatments, the wrapping of the article with a transfer support (2) carrying the decorations wished, the covering of the part so wrapped within a membrane (5) of rubber or the like and the creation of vacuum through holes (6) between the membrane and the piece covered by the same, on prior interposition of means (3) suitable to ensure the flow and the exhaust of the air so as to cause the adhesion of the support to the shape of the article, as well as the possible interposition of yielding means (4), suitable to equalize the pressure exercised by the membrane and lastly the heating for the transfer of the pattern and the polymerization of the colors.
