• the base sheet 13, the intermediate sheet 1 and the transparent protective film 1 1 are connected together by a common binding 19.
• the intermediate sheet 1 is interposed between the basic sheet 13 of the document and the transparent protective film 11.
• the face 7 from the bottom 2 of the intermediate sheet 1 opposite the film 3 of this sheet 1 is oriented towards the base sheet 13.
• the face 9 of the transparent protective film 1 1 intended to receive the film 3 of the intermediate sheet 1 with variable inscriptions 8, is oriented towards the film 3 of the intermediate sheet 1.
• This face 9 is the free face of the adhesive layer 10 of the transparent protective film 1 1 oriented towards the sheet 1.
• a detachable non-stick sheet 20 is interposed between the intermediate plug 1 and the transparent protective film 11 in order to avoid inadvertent sticking before use of the adhesive layer 10 of the protective film ector 1 1 on the film 3 of the intermediate sheet 1.
• This sheet 20 is for example constituted by a simple sheet of silicone paper at least on the side of the film 1 1.
• the film 3 and the layer of adhesive 10 can be protected by separate release sheets, one for the film 3 and another for the adhesive layer 10.
• the intermediate sheet 1 is connected by its bottom 2 to the binding of the document and the transparent protective film 11 is connected by its support sheet 18 which relates to the binding of the document.
• the intermediate sheet 1 and / or the transparent protective film 11 is detachably connected to the binding of the document.
• the bottom 2 is provided with a precut line 21 near the binding 19 making it possible to easily detach this bottom 2 from the document, in particular for the subsequent application of the film 11 on the base sheet 13.
• the detachable non-sticky interlayer sheet 20 is provided with a precut line 22 extending along and near the binding 19, making it possible to detach it from the document.
• the support sheet 18 of the protective film 11 is connected to the binding 19 by means of a pre-cut line 23 formed on this support sheet 18 along and near the binding 19, so that the sheet support 18 can be detached from the document.
• the intermediate sheet 1 and / or the film 1 1 can be supplied separate from the document to be protected.
• variable inscriptions 8 are produced as shown in FIG. 6 on film 3 of sheet 1 by any appropriate means as indicated above.
• the intermediate non-stick sheet 20 is then detached and the sheet 1 is applied against the transparent protective film 11, the film 3 and the adhesive layer 10 of the film 11 being in contact.
• the film 3 is transferred as indicated above with the variable inscriptions 8 onto the transparent protective film 11, then the base 2 is detached by peeling it off from the first layer of heat-activated adhesive 3a and therefore from the film 3, which is then carried by the film 11.
• the transparent protective film 11 is then applied and hot glued, preferably by lamination, on the base sheet 13, then it is peeled off and the support sheet 18 is detached from the film 11.
• the film 3 and the adhesive layer 10, or the layer resulting from said fusion is (are) covered with the transparent protective film 11.
• a document is for example a passport or any other official document of identification and / or authentication.
• the invention can be the subject of numerous variants compared to the embodiments described and shown.
• the intermediate sheet 1 can be separated and presented in the form of an insert placed in the booklet or even completely independently of the document and / or the film 11.
• the document can also be presented in any form other than a booklet ( paper and / or plastic card ). It may include several base sheets 13, but an intermediate sheet 1 and a transparent protective film 1 1 is provided for each page to receive variable inscriptions 8.
