Abstract:
1. A method for decorating objects, in particular containers in general, using a device comprising at least two reels, at least one of which is motorized, to which the ends of a non-stick film are connected, the non-stick film being made of one of a paper material or a polyester material covered with silicon on both surfaces, one of said surfaces acting as a support for a plurality of images created from dry thermoplastic ink, at least two tension rollers for the non-stick film, at least one pressing element positioned between the tension rollers, and at least one heat generator which has-a heated air dispenser directed towards the non-stick film, said method comprising the steps of: electrostatic application of dry thermoplastic inks to the non-stick film, the application being designed to form an image which will constitute the decoration of the object, a transformation on the surface of a non-stick film of a thermoplastic ink of the image from a dry powdery state to a semi-liquid plastic state through the action of heated air blown from a heat generator against the non-stick film that causes a detaching of the images from the non-stick film and an adhesion of the image to the surface of the object to be decorated, the adhesion occurring as a result of the action of mechanical pressure exerted by a pressing element on the non-stick film against the surface of the object to be decorated, and of the images which are exposed to the heating effect of the hot air from the heat generator, being able to effect the adhesion of the images on the objects to be decorated followed by subsequent solidification of the inks of the images on the object as the images cool and a dispenser is positioned on the side of the surface of non-stick film bearing the images or on the opposite side; the positioning being variable according to the variable resistance to the temperature of the material constituting the object to be decorated; the variable positioning of the dispenser making the decoration procedure free of restrictions of a chemical nature of the surfaces of the object to be decorated.
