    [0002] PROCEDURE FOR THE MANUFACTURE AND PAINTING OF SAUSAGED CHARACTERS
    [0004] OBJECT OF THE INVENTION
    [0006] The invention, as expressed in the wording of the present specification, refers to a procedure for the manufacture and painting of characters embedded in license plates and heat-transferrable tubular sheet to carry out said method, providing advantages and characteristics, which are described in detail below, which represent a remarkable improvement over the current state of the art.
    [0008] More specifically, the object of the invention focuses on a process for the manufacture of license plates, in particular for the stage of painting the embossed characters in relief by applying heat-transferrable ink through a tubular sheet that facilitates To a great extent, said operation and, consequently, makes the process of making the license plate more economical, a second aspect of the present invention being said tubular sheet with heat transfer ink.
    [0010] FIELD OF APPLICATION OF THE INVENTION
    [0012] The field of application of the present invention is framed within the sector of the industry dedicated to the manufacture of license plates, in particular license plates for vehicles, focusing particularly on license plates.
    [0014] BACKGROUND OF THE INVENTION
    [0016] As is known, one of the most common procedures applied to manufacture license plates comprises at least one stage of embossing the identifying characters on the aluminum plate with reflective from which it starts, often embossing at the same time a perimeter edge, which can be carried out with any of the machines or devices with drawing dies, whether they are manually or motorized on the market, and, at least, another stage of thermal stamping in which I know obtains the painting of the upper part of the relief obtained in the previous stage of embossing said characters, and in its case of the perimeter edge, by applying heat-transferrable ink impregnated in a sheet that is placed on the plate already inlaid, through a thermal stamping machine that applies pressure and heat in a controlled manner to said inlay plate and ink sheet assembly.
    [0018] The problem with this procedure is the difficulty of said thermal stamping step, since it requires fitting the heat transfer ink sheet onto the embossed plate since, until now, said sheet has exactly the same size as the plate, to be able to pass without problem In the groove between the rollers of the machine it is stamping, since if it is wider it could get caught and wrinkled, deteriorating the quality of the printing, and also when they protrude around the perimeter stain these rollers with ink, which makes constant cleaning necessary . And, if its dimension is smaller, logically, parts of the relief would remain unpainted, with the consequent defective result of the plate.
    [0020] Consequently, the current method of making this type of plates requires, in addition to dexterity on the part of the operator for the perfect alignment of the heat transfer ink sheet on the embedded plate, the application of the time necessary to correctly carry out said alignment without the ink deteriorating due to rubbing in repeated attempts that, on the other hand, involve an expense in discarded material.
    [0022] An example of the prior art can be found in document ES 2645194 A1, of the Applicant himself, referring to a method of manufacturing license plates.
    [0024] The objective of the present invention is, therefore, to provide a process that allows to eliminate said difficulty in the thermal stamping stage and to achieve the placement of the heat transfer ink sheet on the embossed plate in a much faster and simpler way that, in addition, ensures a correct placement in all cases the first attempt, avoiding the waste of material, through the use of a tubular sheet instead of the sheet of identical dimension to that of the plate.
    [0026] On the other hand, and as a reference to the current state of the art, it should be noted that, at least by the applicant, the existence of any procedure for making license plates or any heat transfer tubular sheet to carry out said method is unknown. , nor any other invention of similar application, which presents technical, structural and constitutive characteristics equal or similar to those presented by what is claimed here.
    [0028] EXPLANATION OF THE INVENTION
    [0030] The procedure for making and painting characters embedded in license plates and thermotransferable tubular sheet to carry it out that the invention proposes allows to satisfactorily achieve the aforementioned objectives, being the characterizing details that make it possible and that distinguish it conveniently collected in the final claims accompanying the present description.
    [0032] More specifically, the method that the invention proposes, as noted above, is a procedure that, in a known manner, comprises:
    [0034] - At least one stage of embossing identifying characters in an aluminum plate that incorporates on its front face a sheet of reflective material, being able to contemplate or not the simultaneous embossing of a perimeter edge, said embossing being carried out with any type of machine or device existing drawing, manual or motorized; Y
    [0035] - At least one stage of thermal stamping for painting the upper part of the relief obtained in the previous stage of embossing the characters, and where appropriate the perimeter edge, by applying heat transfer ink impregnated in a sheet on the plate already drawn, through a thermal stamping machine with rollers that apply pressure and heat in a controlled manner to said set of drawn plate and ink sheet.
    [0037] And, in an innovative and advantageous way, the process of the invention is distinguished by the fact that, in the described stage of thermal stamping to paint the upper part of the relief of the characters, and where appropriate the perimeter edge, the application of the heat-transferrable ink impregnated in the sheet on the already drawn plate is carried out comprising the following phases:
    [0039] - introduction of the plate inside a tubular sheet that constitutes said sheet impregnated with heat-transferrable ink,
    [0040] - closure of the open end or ends of said tubular sheet,
    [0041] - introduction of the tubular sheet assembly with the plate inside it in the stamping machine, and
    [0042] - extraction of the finished plate from the inside of the tubular sheet.
    [0044] This avoids the difficulty of having to make the edges of an ink sheet fit exactly on the edges of the plate, since being a tubular sheet in which the plate is inserted internally, the fit is always perfect.
    [0046] For its part, and to ensure that said procedure can be carried out properly, said tubular sheet is made up of two laminar layers, one upper and one lower, joined together along their respective sides and internally incorporates the heat-transferrable ink on at least the inner wall of the upper laminar layer, so that it will be in direct contact with the upper face of the embedded plate.
    [0048] Preferably, these two laminar layers have a width similar to the width of the plate to be made, specifically a slightly greater width, and more specifically just enough so that the plate fits without difficulty inside but without too much slack, to allow insertion of the assembly without difficulty between the rollers of the stamping machine.
    [0050] Preferably, in addition, the tubular sheet has the configuration of a bag and, said two upper and lower laminar layers that form it, in addition to being joined laterally, are also joined at one of their ends, facilitating the correct placement of the plate inside. when abutting said end.
    [0052] Preferably, the tubular sheet also has closure means, either at both ends if it is not in the shape of a bag, or at the open end of said bag, which, consisting of adhesive, facilitate the immobilization of the plate inside the bag during the stamping process.
    [0054] DESCRIPTION OF THE DRAWINGS
    [0056] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, the present specification is accompanied, as an integral part thereof, by a set of drawings in which with Illustrative and non-limiting character, the following has been represented:
