Description

[0001] "Pre-laminate for forming a data page of an identification booklet and method of manufacturing the data page"

[0002] TECHNICAL FIELD

[0003] This generally relates to electronic passports and other identification booklets. The present invention more particularly relates to a data page intended to be attached to an identification booklet.

[0004] STATE OF THE ART

[0005] There are several data pages and associated manufacturing methods. The methods generally involve providing a pre-laminate for forming a data sheet of the data page and a material for forming the hinge of the data page, and then suitably placing them between laminating plates for heat pressing.

[0006] Thus, documents WO 2017 / 071936 A1 and WO 2018 / 138243 A1 make it possible to obtain a data page with different configurations of the connection between data sheet and hinge.

[0007] While these data pages and manufacturing processes more or less meet the specifications of providing: a. a hinge satisfactorily attached to a data sheet, b. a hinge that is easy to sew to form the identification booklet, and c. a hinge that is sufficiently flexible to allow the identification booklet to be properly closed, it is nonetheless desirable to provide at least a manufacturing process that is easier to implement and / or more viable in its implementation, including when several players, sometimes geographically distant, are involved in the manufacturing. We do indeed encounter situations in which first parts of the data page are produced by a first player in the sector to be delivered to second players who add other parts, possibly for personalization, to the parts provided in order to finish manufacturing each data page.The first parties provided, while potentially specific (e.g., to a country or region), may only be customizable and not yet personalized; typically, the personalization data may not be held by the first party, but only by the second parties.

[0008] The present invention therefore aims to propose a manufacturing method that is easy to implement and / or viable in its implementation, including, but not limited to, responding to such commercial situations, and especially for the benefits of the second actors mentioned above.

[0009] SUMMARY

[0010] To achieve this objective, according to a first aspect of the invention, a pre-laminate is provided for forming at least one data page each comprising a data sheet and a hinge, the pre-laminate being essentially such that it comprises: a. A board comprising at least: i. a so-called corelam area, each treated so as to be intended to form at least one intermediate layer of the data sheet, and ii. a sacrificial area extending from a part of the periphery of each corelam area, Each corelam area having, on another part of its periphery, a so-called bonding edge by which the intermediate layer of the data sheet is intended to be bonded to the hinge; b. a first tab and a second tab each comprising at least: i. a hinge area, and

[0011] II. a sacrificial zone, extending from a part of the perimeter of each hinge zone,

[0012] Each hinge area of ​​the first tab being superimposed on a corresponding hinge area of ​​the second tab forming a pair, each pair of hinge areas extending beyond a corresponding corelam area from its bonding edge, and

[0013] Each sacrificial area of ​​the first tab being superimposed on a corresponding sacrificial area of ​​the second tab forming a pair, each pair of sacrificial areas of the first tab and the second tab sandwiching a portion of the sacrificial area of ​​the board on at least one so-called bonding area.

[0014] It is therefore possible to provide such a pre-laminate to the second actors mentioned above, who will then have to: a. Provide a front face and a back face of the data sheet, b. Place successively, between two lamination plates, the front face of the data sheet, the pre-laminate provided and the back face of the data sheet, the front and back faces of the data sheet being superimposed on each corelam zone that the pre-laminate comprises and not covering the hinge zones of the first and second tabs, then c. Heat press the two lamination plates, to produce a data page, fulfilling in particular the specifications mentioned above.

[0015] Such a method is the subject of a second aspect of the present invention.

[0016] An intermediate product is thus proposed taking the form of the pre-laminate as introduced above, allowing at the very least the easy and / or viable production of a data page, including when several actors, sometimes geographically distant, are involved in this production.

[0017] According to a first example, at least one of the first tab and the second tab may further comprise at least one overlapping area extending from another portion of the periphery of each hinge area, each overlapping area extending over a portion of a corresponding corelam area extending from its connecting edge. Additionally, the other of the first tab and the second tab also comprises at least one overlapping area extending from another portion of the periphery of each hinge area, each overlapping area of ​​the first tab may be superimposed on a corresponding overlapping area of ​​the second tab to form a pair, each pair of overlapping areas sandwiching a portion of a corresponding corelam area extending from its connecting edge.

[0018] According to a second example, alternative or complementary to the first example, each tab can be fixed to the board at each connection area, so that each tab is held in position relative to the board. More particularly, each tab can be fixed to the board by at least one welding point, preferably by at least one direct welding point, at each connection area.

[0019] According to a third example, alternative or complementary to one and / or the other of the first example and the second example above, the first tab having a first face located opposite a first face of the second tab when the tabs are fixed to the board, the first face of the first tab is at least partially complementary to the first face of the second tab, at least at the hinge areas of the first tab and the second tab. In combination with the first example above, the first tab and the second tab are preferably substantially planar at the overlap areas.

[0020] According to a fourth example, alternative or complementary to the examples given above, the first tongue having a first face located opposite a first face of the second tongue when the tongues are fixed to the board, at least one of the first face of the first tongue and the first face of the second tongue comprises a protuberance of a height, measured perpendicular to a main extension plane of the tongue, less than or substantially equal to a thickness of the board.

[0021] According to the preceding example, at least one protrusion of at least one of the first face of the first tongue and the first face of the second tongue has at least one first lateral face substantially perpendicular to the main extension plane of the tongue and extending from an edge of the hinge zone of the tongue; a positional wedging of at least one hinge zone of at least one tongue in the pre-laminate is thus obtained, this wedging being particularly appreciable for simplifying the positioning of at least one of the tongues before its fixing to the board at the level of at least one connection zone.In addition, said edge of the hinge zone is that from which a sacrificial zone of the tongue extends, the protrusion preferably being comprised by a portion of the sacrificial zone of the tongue, where appropriate this portion being located outside each connecting zone; the aforementioned framing is thus permitted at the level of at least one sacrificial zone of the tongue, without necessarily creating an excess thickness of the hinge thus obtained. In addition or as an alternative, the pre-laminate according to the first example given above may be such that said edge of the hinge zone is that from which an overlapping zone of the tongue extends, the protrusion being comprised by at least a portion, preferably only a portion, of the hinge zone of the tongue.

[0022] According to a variant of the fourth example, at least one protrusion of the first face of the first tab may have at least one second lateral face located opposite a second lateral face of a protrusion of the first face of the second tab. In addition, each second lateral face of each protrusion may be substantially perpendicular to the main extension plane of the tab from which the protrusion extends. In addition or as an alternative, a second lateral face of at least one protrusion may be opposite a first lateral face of the protrusion concerned; they are for example parallel to each other. In addition or as an alternative, a second lateral face of a protrusion may be adjacent to a first lateral face of the protrusion concerned; they are for example perpendicular to each other.

[0023] According to a fifth example, the board may comprise at least one pair of corelam zones, the corelam zones of each pair being arranged head to tail on either side of an opening in the board forming at least two connecting edges and each opening may delimit at least two pairs of hinge zones of the tabs, and wherein the first tab and the second tab each comprise at least: a. Two hinge zones, and b. Two sacrificial zones each extending from a portion of the periphery of one of the two hinge zones. In addition to and in combination with at least the first example given above, the first tab and the second tab may each further comprise at least: c. Two overlap zones each extending from another portion of the periphery of one of the two hinge zones.

[0024] A combination of at least the third example and the fifth example given above may be such that at least one protrusion of the first face of the first tab and at least one protrusion of the first face of the second tab may complement each other to fit at least partially, preferably completely, an inner circumference of the opening, or even of each opening of the board, and preferably only an inner circumference of the opening, or even of each opening, of the board. It is thus envisaged that each protrusion extends only over a limited, or even very limited, part of the first face of each tab, a larger part of the surface of each first face of each tab remaining flat; this makes it possible to obtain a thinner, and therefore notably more flexible, hinge.

[0025] According to a variant of the fifth example, the board may comprise at least two pairs of corelam areas, at least two openings each forming two connecting edges for each pair of corelam areas, and at least one hinge separation sacrificial area extending between two mutually adjacent openings, each tab further comprising an additional sacrificial area, the additional sacrificial area of ​​the first tab and the additional sacrificial area of ​​the second tab being superimposed on each other and sandwiching the hinge separation sacrificial area of ​​the board on at least one additional connecting area, the first face of each tab preferably being planar at the additional sacrificial area.

[0026] According to another variant of the fifth example, combinable with the previous one, the board may comprise at least two pairs of corelam areas, at least two openings each forming two connecting edges for each pair of corelam areas, and at least one sacrificial hinge separation area extending between two mutually adjacent openings, each tab further comprising an additional sacrificial area, the additional sacrificial area of ​​the first tab and the additional sacrificial area of ​​the second tab being superimposed on each other and sandwiching the sacrificial hinge separation area of ​​the board on at least one additional connecting area, the first face of each tab being preferably flat at the additional sacrificial area. A greater level of fixing of the tabs to the board is thus achieved.And this, even more particularly, if each tab is fixed to the board at the additional connection area, each tab being able to be fixed to the board by at least one welding point, preferably by at least one direct welding point, at the additional connection area.

[0027] According to another variant of the fifth example, which can be combined with any of the previous ones, the two tabs can be identical to each other and rotated 180° relative to each other in the pre-laminate. This makes it easier to manufacture the tabs.

[0028] According to another example: a. The data page may be intended for at least one identification booklet and the data sheet may be intended to be linked to the rest of the identification booklet by the hinge, and / or b. The hinge may be more flexible than the data sheet, and / or c. The intermediate portion of the data sheet may have substantially the same extent as the data sheet.

[0029] Furthermore, the data sheet may further be intended to comprise a front face and a back face, the intermediate layer being intended to be sandwiched between the front and back faces. BRIEF DESCRIPTION OF THE FIGURES

[0058] DETAILED DESCRIPTION

[0059] “Direct welding” between two elements means welding without adding material between these two elements.

[0060] The term "pre-laminate" means a superposition of layers arranged in a particular way relative to each other and intended to be laminated together; by contrast, the term "pre-laminate" means a pre-laminate which has undergone a first lamination, even partial, and intended to be laminated again with other layers arranged in a particular way relative to the pre-laminate.

[0061] The pre-laminate 100 according to the different embodiments of the first aspect of the invention which are presented below with reference to the different appended figures is intended to allow the manufacture of a data page 1 for an identification booklet 0 as illustrated in Figure 8. Each data page 1 comprises a data sheet 2, on which at least part of the identification data is located, and a hinge 3 suitable for allowing the connection of the data page 1 with the rest of the identification booklet 0. This connection is for example carried out using a sewing thread 5, along a suture axis 10 of the data page 1 to the rest of the identification booklet. In particular, when the identification booklet 0 constitutes a passport, the identification booklet may comprise a certain number of pages 4, as illustrated in Figure 8.

[0062] A first embodiment of the first aspect of the invention is described below with reference to Figures 1A to 1D.

[0063] Figure 1A illustrates a top view of a board 101 of a pre-laminate 100 according to the first embodiment of the invention. The board 101 comprises a corelam area 1011 treated so as to be intended to form at least one intermediate layer 21 of a data sheet 2. The board 101 further comprises a sacrificial area 1012 extending from a part of the periphery of the corelam area 1011. The area 1012 is called sacrificial because it is not intended to be part of the data page 1 which will be inserted into the identification booklet 0; it will be cut so as to obtain the data page 1. The same will apply to any other sacrificial areas.

[0064] As illustrated in Figure 1A, the sacrificial zone 1012 does not extend from all the edges of the corelam zone 1011. On the contrary, the corelam zone 1011 has, on a part of its periphery, an edge 10111 by which the intermediate layer 21 of the data sheet 2 is intended to be bonded, directly or indirectly, but preferably directly, to the hinge 3 of the data page 1. Note that the sacrificial zone 1012 of the board 101 extends at least on one side, preferably on either side, of a zone extending from the bonding edge 10111 and intended to accommodate the hinge zones 1021 and 1022 of two tabs 102 and 103 of the pre-laminate according to the first aspect of the invention which are described below with reference to Figures 1B and 1C.

[0065] Let us note here that, in any of the embodiments described below, each corelam zone 1011 may comprise, in particular embedded within it, an electronic chip 210 and a radiofrequency antenna 220. Identification data, in particular biometric data, may be stored or be intended to be stored on the electronic chip 210, the latter being capable of communicating to the outside thanks to the radiofrequency antenna 220, at least to allow the reading of the identification data. As illustrated in FIGS. 6A and 6B, the corelam zone may also comprise a transparent zone 230 acting as a security window by virtue of its shape and / or by accommodating or being intended to accommodate one or more authentication devices.

[0066] More particularly, a corelam zone 1011 may, with reference to FIG. 6A, successively comprise several layers based on different materials, for example a thermoplastic polymer such as polycarbonate or a polyamide, transparent or opaque. Each layer constituting a corelam zone 1011 may have a thickness substantially equal to a few tens of microns and generally not exceeding 100 microns, so in particular that each corelam zone has a thickness substantially between 200 and 500 microns, preferably between 300 and 400 microns, for example equal to 325 microns. FIGS. 1B and 1C each illustrate one of the two tabs 102 and 103 constituting the prelaminate 100 according to the first embodiment of the invention. It appears, in these figures, that each of the tabs 102, 103 has a hinge zone 1021, 1031 and at least one sacrificial zone 1023, 1024, 1033, 1034.Each sacrificial zone extends from a portion of the perimeter of each hinge zone.

[0067] The first 102 of the two tabs is illustrated in Figure 1B. In the illustrated example, it has a protrusion 1027 extending from a first face 102a of the first tab 102, and more particularly from a part of the hinge zone 1021 of the first tab 102. Note here that the first protrusion 1027 has two lateral faces 10272 opposite one another.

[0068] The second 103 of the two tabs is illustrated in Figure 1C. In the illustrated example, it has two protrusions 1037 and 1038 extending from a first face 103a of the second tab 103, and more particularly from a portion of the hinge zone 1031 of the second tab 103. Note here that each of the protrusions 1037 and 1038 has two lateral faces referenced 10371 and 10372 for the first 1037 of the two protrusions and referenced 10381 and 10382 for the second 1038 of the two protrusions. In the pre-laminate 100 according to the first embodiment of the invention, the first and second tabs 102 and 103 are arranged relative to each other, so that the hinge area 1021 of the first tab 102 is superimposed on the hinge area 1031 of the second tab 103.The hinge areas 1021 and 1031 thus form a pair, which, as illustrated in Figure 1D, extends, in the pre-laminate 100, beyond the corelam area 1011 of the board 101, and from the bonding edge 10111 of the corelam area 1011. The first and second tabs 102 and 103 are further arranged relative to each other such that each sacrificial area 1023, 1024 of the first tab 102 is superimposed on a corresponding sacrificial area 1033, 1034 of the second tab 103. More particularly, the sacrificial areas 1023 and 1024 form a first pair and the sacrificial areas 1033 and 1034 form a second pair of sacrificial areas superimposed on each other.The first and second tabs 102 and 103 are further arranged relative to each other such that each pair of sacrificial zones of the tabs 102 and 103 sandwiches a portion of the sacrificial zone 1012 of the board 101. Two connecting zones 1041 and 1042 are thus created on each of which are successively superimposed on each other a sacrificial zone 1023, 1033 of the first tab 102, a sacrificial zone 1033, 1034 of the second tab 103 and a portion of the sacrificial zone 1012 of the board 101.

[0069] Each tab 102, 103 is then connected to the board 101 at least at the level of each of the two connection zones 1041 and 1042. Note that it is not necessary, even if preferable, to provide two connection zones 1041 and 1042, one of the two being able to suffice if necessary. More particularly, each tab 102, 103 can then be fixed to the board 101, so that each tab 102, 103 is held in position relative to the board 101. Even more particularly, each tab 102, 103 can be fixed to the board 101 by at least one solder point 10411, 10412 at each connection area 1041, 1042. In FIG. 1 D, a single solder point 10411, 10412 is shown on each connection area 1041, 1042, but it is understood that each connection area can have several solder points.Preferably, each welding point is obtained by direct welding, that is to say without adding material, unlike welding by brazing, or simple gluing, which are not excluded. If necessary, and depending on the specific case, it may be necessary to characterize or have characterized the welding parameters which optimize the fixing of each tab 102, 103 on the board 101, without damaging the materials present, in particular outside the so-called sacrificial zones.Among such parameters, the thickness and nature of the different layers to be fixed together, the dimensions of a heat-sealing probe, and in particular the diameter of its end (for example substantially equal to 2 mm), the temperature and pressure exerted via the heat-sealing probe at each welding point, the time during which the pressure is exerted, as well as, where appropriate, the parameters characterizing the support on which the welding points are made, may be considered. Furthermore, it should be noted that, if we are talking above about welding points, it is not excluded that the welds take more the form of segments, where appropriate connected to each other, for example by their ends.

[0070] In Figure 1D, and in view of Figures 1A to 1C, it will be noted that the protrusions 1037 and 1038 which extend from the first face 103a of the second tab 103 are at least partially complementary to the protrusion 1027 which extends from the first face 102a of the first tab 102. More particularly, the second lateral face 10372 of the protrusion 1037 of the second tab 103 is opposite, or even in abutment or in support, on one of the two second lateral faces 10272 of the protrusion 1027 of the first tab 102, while the second lateral face 10382 of the other protrusion 1038 of the second tab 103 is opposite, or even in abutment or in support on the other of the two second lateral faces. 10272 of the protrusion 1027 of the first tab 102.Furthermore, the first lateral face 10371, 10381 of each of the protrusions 1037, 1038 of the second tab 103 is opposite, or even in abutment or in support, on an inner edge of a corresponding one of the two connecting zones 1041, 1042. In addition, other lateral faces 10273, 10373 and 10383 of the protrusions 1027, 1037 and 1038 come, in the pre-laminate 100, opposite, or even in abutment or in support, on the connecting edge 10111 of the corelam zone 1011.

[0071] Whether by placing second lateral faces opposite each other, or even in abutment or in support, and / or by placing a first lateral face opposite each other, or even in abutment or in support, with at least a portion of the inner edge of a connecting zone and / or by placing other lateral faces opposite each other, or even in abutment or in support, with the connecting edge 10111 of the corelam zone 1011, it is understood that several lateral faces of the protuberances 1027, 1037 and 1038 are advantageously used to constitute a system of stops facilitating centering, or even constituting a foolproof device, for the placement of each tab 102, 103 relative to each other and relative to the board 101. This achieves relative ease of placement of each tab 102, 103 relative to the board 101 and the other tab, in particular for a significant saving in terms of assembly time of the pre-laminate 100.Each of the embodiments described below demonstrates this advantage.

[0072] Preferably, the lateral faces of the protrusions 1027, 1037 and 1038 are substantially perpendicular to the main extension plane of the tongue 102, 103 carrying the protrusion, especially when the lateral edge concerned is intended to be placed opposite, or even in abutment or in support, on another lateral face or on the connecting edge 10111. Note, however, that it is not excluded that the lateral faces are inclined relative to the perpendicular. It will be noted that the hinge zones 1021 and 1031 can be structured in thickness, by the protrusions 1027, 1037 and 1038, so that, when superimposed on each other, the hinge zones 1021 and 1031 of the two tongues have substantially the same quantity of material per sub-zone of the hinge zones; this is achieved, in the case of the first embodiment, since the protrusions 1027, 1037 and 1038 together cover the entire hinge area.This ensures that each hinge 3 manufactured is of a controlled thickness and substantially constant over its entire extent.

[0073] For example, a first layer of polyurethane may constitute a base of each of the tabs 102 and 103 and cutouts in a second layer of polyurethane may constitute the protrusions 1027, 1037 and 1038 to be transferred onto the first base layer to form the tab. For example, the first base layer and the second layer from which the protrusions are cut have thicknesses that are substantially equal to each other, typically substantially equal to 150 microns. For example, each cutout constituting a protrusion may be glued or pre-laminated onto the corresponding first base layer.Note that, according to this example, each tab locally has a maximum thickness substantially equal to 300 microns, and that the tabs 102 and 103 superimposed on each other in the pre-laminate 100 have, over the entire extent of the hinge zones 1021 and 1031, a thickness substantially equal to 300 microns, due to the complementarity between them of the protuberances 1027, 1037 and 1038 over the extent of the hinge zones 1021 and 1031.

[0074] Let us note here that, as we will see in particular through the description of the embodiment of the invention which is illustrated in FIGS. 5A to 5D, the pre-laminate 100 according to the invention is not limited to a complementarity between tabs leading to a constant thickness of material at the hinge zones 1021 and 1031 superimposed on each other. If necessary and for convenience, we will speak of a “solid form” of the pre-laminate 100 according to the invention, when the complementarity between tabs leads to a constant thickness of material at the hinge zones 1021 and 1031 superimposed on each other, and we will speak of a “hollow form” of the pre-laminate 100 according to the invention, when the complementarity between tabs does not lead to a constant thickness of material at the hinge zones 1021 and 1031 superimposed on each other.

[0075] While it is envisaged here to cut the protuberances from a polyurethane layer before transferring them to a polyurethane base layer, other techniques are envisaged or may be envisaged for manufacturing each tab 102, 103. For example, each tab could be produced by molding the material constituting it.

[0076] It is envisaged here that each hinge will be made of polyurethane. This choice of materials is judicious in that it provides the hinge with both flexibility and transparency properties that meet the specifications. However, the material constituting each tab is not limited to polyurethane, although this choice is advantageous.

[0077] Preferably, each protrusion 1027, 1028, 1037 and 1038 has a height, measured perpendicular to a main extension plane of the tongue 102, 103, less than or substantially equal to a thickness of the board 101. This ensures that no local excess thickness is created in the pre-laminate 100, or even in the data page 1, in particular at the hinge 3 of the data page 1; such excess thickness could locally impair the ability of the hinge 3 to flex, which is not desirable.

[0078] Still with reference to Figures 1A to 1D, at least one of the first tab 102 and the second tab 103 may further comprise at least one overlap zone 1025, 1035. Each overlap zone 1025, 1035 extends from another part of the periphery of each hinge zone 1021, 1031, relative to the part of said periphery from which each sacrificial zone extends. In the pre-laminate 100, each overlapping zone 1025, 1035 further extends over a portion of the corelam zone 1011 of the board 101, this portion extending from the connecting edge 1011 of the corelam zone 1011. The retention in position of said at least one tab 102, 103 in the pre-laminate 100 is thereby reinforced. Also, this feature provides an overlap between the material intended to form the hinge 3 and the material intended to form the intermediate layer 21 of the data sheet 2.A larger bonding surface between the intermediate layer 21 and the hinge 3 is thus achieved, in particular relative to a non-excluded case according to which the contact surface between the intermediate layer 21 and the hinge 3 would be limited to the lateral face of the corelam zone 1011 which comprises the bonding edge 10111. This characteristic is likely to increase the resistance to tearing, between them, of the intermediate layer 21 and the hinge 3.

[0079] Additionally, the other of the first tab 102 and the second tab 103 may also comprise at least one overlapping area 1025, 1035 extending from another part of the periphery of each hinge area 1021, 1031, relative to the part of said periphery from which each sacrificial area extends. When the tabs 102 and 103 are in position relative to the board 101, the overlapping area 1025 of the first tab 102 is superimposed on the overlapping area 1035 of the second tab 103; they form a pair of overlapping areas 1025 and 1035 sandwiching a part of the corelam area 1011 which extends from the bonding edge 10111. This further increases the contact surface between the intermediate layer 21 and the hinge 3, which is likely to further increase the resistance to tearing of the intermediate layer 21 and the hinge 3 from each other.

[0080] It is clear from the above that at least three types of bonding of the intermediate layer 21 and the hinge 3 to each other are possibly achieved by means of the pre-laminate 100 according to the invention. The first of these three types of bonding is that which concerns patent application WO 2018 / 138243 A1. According to this type of bonding, the intermediate layer 21 and the hinge 3 are here bonded to each other only at the bonding edge 10111 of the corelam zone 1011. The second of the three types of bonding is that which concerns patent application WO 2017 / 071936 A1. According to this type of connection, illustrated in Figure 1 D, the intermediate layer 21 and the hinge 3 are here connected to each other not only at the connection edge 10111 of the corelam zone 1011, but also by sandwiching a part of the corelam zone 1011 which extends from the connection edge 10111.The third of the three types of bonding is a hybrid mode between the first and second types of bonding. More particularly, according to this third type of bonding, the intermediate layer 21 and the hinge 3 are here bonded together at the bonding edge 10111 of the corelam zone 1011 and at a portion of only one of the two main faces of the corelam zone 1011. As illustrated in FIGS. 1 B and 1 C, the overlapping zones 1025 and 1035 are free of protrusion. More particularly, the different solid shapes of the pre-laminate 100 according to the invention are achieved by considering that at least one protrusion 1027, 1037 and 1038 of at least one tab 102, 103 extends over the hinge zone 1021, 1031 of the tab from its overlap zone 1025, 1035.

[0081] The second embodiment of the first aspect of the invention is described below with reference to Figures 2A to 2D.

[0082] The second embodiment of the first aspect of the invention is quite comparable to the first embodiment in that the latter can be 'seen' as one half of the second embodiment.

[0083] According to the second embodiment of the invention, the board 101 comprises a pair of corelam zones 1011. As illustrated in FIG. 2A, the corelam zones 1011 of the pair are arranged head to tail on either side of an opening 10112 made in the board 101 and forming two connecting edges 10111, and more particularly one connecting edge 10111 per corelam zone 1011. The head to tail arrangement of the corelam zones 1011 between them makes it possible to obtain data pages 1 having the same orientation of the data sheet 2 relative to the hinge 3, each of the two data pages 1 thus produced being subsequently able to be integrated into the rest of an identification booklet 0 in the same way as the other can be integrated into the rest of another identification booklet 0, for the same rendering, with the identification data close.

[0084] It is immediately apparent that the second embodiment aims to enable the manufacture of two data pages 1 by implementing a single lamination operation and from a single pre-laminate 100.

[0085] Just as it emerges by comparing Figure 2A with Figure 1A that the board 101 of the pre-laminate 100 according to the second embodiment is obtained by 'replication' of the board 101 of the pre-laminate 100 of the first embodiment, it emerges by comparing Figure 2B with Figure 1B and Figure 2C with Figure 1C that each of the tabs 102 and 103 of the pre-laminate 100 according to the second embodiment is obtained by 'replication' of a respective one of the tabs 102 and 103 of the pre-laminate 100 according to the first embodiment.

[0086] The most essential difference between the tabs 102 and 103 of the first and second embodiments appears by considering that the opening 10112 which, according to the second embodiment, is made in the board 101 delimits a first pair of hinge zones 1021 and 1031 and a second pair of hinge zones 1022 and 1032. Thus, it appears that each of the first tab 102 and the second tab 103 comprises two hinge zones (referenced 1021 and 1022 for the first tab 102 and referenced 1031 and 1032 for the second tab 103). Note that each of the first tab 102 and the second tab 103 further comprises two sacrificial zones (referenced 1023 and 1024 for the first tab 102 and referenced 1033 and 1034 for the second tab 103).

[0087] It will be noted that, relative to the illustrations of the sacrificial zones 1023, 1024, 1033 and 1034 and the protrusions 1027, 1037 and 1038 of the tabs 102 and 103 of the first embodiment (see figures 1B and 1C), the sacrificial zones 1023, 1024, 1033 and 1034 and the protrusions 1027, 1037 and 1038 of the second embodiment (see figures 2B and 2C) each have substantially doubled in surface area. Therefore, and with reference to FIG. 2D, on the one hand each tab 102, 103 can advantageously be fixed to the board 101 by more welding points 10411 relative to the first embodiment, on the other hand the first and second tabs 102 and 103 are intended to form no longer a single hinge 3, but two hinges 3. These two hinges 3 are defined on either side of axes of symmetry 2000 and 2001 of each tab 102, 103 which are aligned with each other, when the tabs 102 and 103 are in position on the board 101.

[0088] It will be noted that, if the second embodiment has the advantage over the first of allowing the production of two data pages 1 in a lamination step and from a single pre-laminate 100, they also have the advantage of offering ease of placement, and in particular of centering, using the stops produced by the protuberances 1027, 1037 and 1038, of the tabs 102 and 103 relative to the board 101, or even of offering better support for the tabs 102 and 103 on the board 101.

[0089] It will also be noted that each tab 102, 103 may further comprise two overlap zones (referenced 1025 and 1026 for the first tab 102 and referenced 1035 and 1036 for the second tab 103), and more particularly one overlap zone per corelam zone 1011 of the pair. In view of FIGS. 2B and 2C, it appears that the overlap zones 1025, 1027, 1035, 1036 of each of the tabs 102 and 103 do not necessarily break the axis symmetry (2000 for the first tab 102 and 2001 for the second tab 103) of each of the tabs 102 and 103.

[0090] It will also be noted that the protrusions 1027, 1037 and 1038 of the two tabs 102 and 103 complement each other to completely fit an inner perimeter of the opening 10112.

[0091] The other features of the second embodiment of the first aspect of the invention are deemed to be described through the description of the first embodiment and / or by any one of Figures 2A to 2D. The third embodiment of the first aspect of the invention is described below with reference to Figures 3A to 3D. Figure 3E illustrates a variant of the third embodiment of the first aspect of the invention.

[0092] The third embodiment of the first aspect of the invention is quite comparable to the second embodiment in that the latter can be 'seen' as one half of the third embodiment.

[0093] According to the third embodiment, the board 101 comprises two pairs of corelam zones 1011. As illustrated in FIG. 3A, the corelam zones 1011 of each pair are arranged head to tail on either side of an opening 10112, 10112' made in the board 101 and forming four connecting edges 1011 1 , and more particularly one connecting edge 10111 per corelam zone 1011 . As in the second embodiment, the head-to-tail arrangement of the corelam zones 1011 in pairs makes it possible to obtain data pages 1 having the same orientation of the data sheet 2 relative to the hinge 3, each of the four data pages 1 thus produced being subsequently able to be integrated into the rest of an identification booklet 0 in the same way that each of the others can be integrated into the rest of another identification booklet 0, for the same rendering, except for the identification data.

[0094] It is immediately apparent that the third embodiment aims to enable the manufacture of four data pages 1 by implementing a single lamination operation and from a single pre-laminate 100. The same will apply to the other embodiments described below. In the example illustrated in FIG. 3A, it appears that the board 101 further has at least one sacrificial hinge separation zone 10113. This sacrificial zone 10113 extends between the two openings 10112 and 10112'. Opposite this sacrificial zone 10113, each tab 102, 103 further comprises an additional sacrificial zone 1029, 1039, illustrated in FIG. 3B for the first tab 102 and illustrated in FIG. 3C for the second tab 103.The additional sacrificial zone 1029 of the first tab 102 and the additional sacrificial zone 1039 of the second tab 103 are superimposed on each other, when the tabs are fixed on the board 101 as illustrated in FIG. 3D. In this fixing position, the additional sacrificial zones 1029 and 1039 of the two tabs 102 and 103 sandwich the hinge separation sacrificial zone 10113 of the board 101 on at least one so-called additional connecting zone 1043. And, in order not to create excess thickness, as well as to limit the waste of material, the first face 102a, 103a of each tab 102, 103 is preferably flat at the level of the additional sacrificial zone 1029, 1039; in other words, the first face 102a, 103a of each tab 102, 103 does not have a protrusion at the level of the additional sacrificial zone 1029, 1039.

[0095] The superposition between them of the sacrificial hinge separation zone 10113 of the board 101 and the additional sacrificial zones 1029 and 1039 of the two tabs 102 and 103 defines the so-called additional connection zone 1043 at the level of which each tab 102, 103 can be fixed to the board 101, for example by means of a welding point 10411 as described above.

[0096] It will be noted that, in the third embodiment of the first aspect of the invention, each of the two tabs has, as in the second embodiment, an axis symmetry (2002 for the first tab 102 and 2003 for the second tab 103). In particular, each of the protrusions 1037 and 1028 of the first tab 102 and each of the protrusions 1037 and 1038 of the second tab 103 extend over the entire width of the opening 101 12, 101 112' in which they are housed.

[0097] The other characteristics of the third embodiment, and in particular those relating to the overlap zones 1025, 1025', 1026, 1026', 1035, 1035', 1036 and 1036', are deemed to be described through the description of the first and second embodiments and / or by any one of figures 3A to 3D.

[0098] As announced above, Figure 3E represents an alternative to the third embodiment illustrated in Figure 3D. According to this alternative, a single opening is made in the board 101 instead of the two openings 10112 and 10112' illustrated in Figure 3A. In this variant, the board 101 therefore no longer has a sacrificial hinge separation zone 10113. Preferably, the space occupied by this zone, in other words the material which in the board 101 made this zone, is to be filled; this is achieved, according to the variant of the third embodiment, thanks to a complementarity of the protuberances between them over the entire extent of the single opening made in the board 101.An intermediate portion between pairs of overlapping zones 1025 and 1025', 1026 and 1026', 1035 and 1035', and 1036 and 1036' which are located on the same side of the axis of symmetry 2002, 2003 of each of the two tabs 102 and 103 can be considered as forming a part of the aforementioned additional sacrificial zones 1029 and 1039 of the two tabs 102 and 103; each pair of intermediate portions can thus constitute, with a part of the sacrificial zone 1012 of the board 101, an additional connecting zone 1043 capable of accommodating one or more fixing points 10413 of each of the tabs 102 and 103 to the board 101, as illustrated in FIG. 3E.

[0099] It is observed that the first and second tabs 102 and 103 according to the third embodiment, as well as according to the variant of this embodiment, are strictly identical to each other, which facilitates their manufacture.

[0100] Note that all the embodiments described above relate to a solid form of the prelaminate 100 according to the invention. The same applies to the fourth embodiment of the first aspect of the invention which is described below with reference to FIGS. 4A to 4D.

[0101] Figure 4A is strictly identical to Figure 3A, which reflects the fact that board 101 of the third embodiment described above is identical to board 101 of the fourth embodiment described below.

[0102] The main difference between this fourth mode and the third mode previously described lies in the fact that the tabs 102 and 103 no longer have axis symmetry (2004 for the first tab 102 (see figure 4B) and 2005 for the second tab 103 (see figure 4C)), but a center symmetry, referenced 2100 for the first tab 102 and 2101 for the second tab 103, in figures 4B and 4C respectively. Therefore, it is the complementarity between them of the protrusions 1027 and 1037 of the first and second tabs 102 and 103 and the complementarity between them of the protrusions 1028 and 1038 of the first and second tabs 102 and 103 which make it possible to fill the two openings 10112 and 10112', in particular over their width. In this fourth embodiment, each protrusion 1027, 1028, 1037, 1038 has, when the tabs 102 and 103 are in position relative to the board 101: a.a first side face, respectively 10271, 10281, 10371, 10381 which faces a bonding edge 10111 of a corelam area 1011 or a portion of the inner edge of a bonding area 1041, 1042, 1043, and b. a second side face, respectively 10272, 10282, 10372, 10382 which faces a second side face of another protrusion.

[0103] It is observed that, unlike the third embodiment described above, the tabs

[0104] 102 and 103 according to the fourth embodiment are then no longer identical to each other.

[0105] Other features of the fourth embodiment are deemed to be described through the description of the first, second and third embodiments and / or by any one of Figures 4A to 4D.

[0106] Figures 5A to 5D illustrate a fifth embodiment of the first aspect of the invention which is described below, and which, unlike the previously described embodiments, has a 'hollow' shape of the pre-laminate 100 according to the invention.

[0107] The idea pursued through this fifth embodiment is to make it possible to reduce the thickness of the hinges 3 manufactured using the pre-laminate 100, without losing the advantage presented by the other embodiments described above and which consists of ease of placement, using a system of stops, of the tabs 102 and 103 relative to the board 101. It is understood that the 'hollow' shape described below in the context of the fifth embodiment of the first aspect of the invention is portable to the first embodiment and to the third embodiment which, respectively, provides for the manufacture of one data page 1 and the manufacture of two data pages 1 , from a single pre-laminate 100.

[0108] This objective is achieved, according to the fifth embodiment of the first aspect of the invention, by providing a board 101 whose openings 10112 and 10112' are not made in the same way as in the examples illustrated in FIGS. 3A and 4A. Indeed, each of the openings 10112 and 10112' illustrated in FIG. 5A is extended, relative to each of the openings 10112 and 10112' illustrated in FIGS. 3A and 4A, by extending into the sacrificial zone 1012 of the board 101, beyond the portion of the openings 10112 and 10112' which are intended to accommodate the hinge zones 1025, 1025', 1026, 1026', 1035, 1035', 1036, 1036'. With reference to FIGS. 5B and 5C, each of the first and second tabs 102 and

[0109] 103 comprises two protrusions, referenced 1027 and 1028 for the first tab 102 and referenced 1037 and 1038 for the second tab 103, one protrusion 1028, 1037 of which takes the shape of a U and the other protrusion 1027, 1038 takes the shape of a bar intended to 'close' the U shape of a protrusion of the other tab, when the tabs 102 and 103 are arranged relative to the board 101.

[0110] With reference to FIG. 5A, the opening extensions 10114, four in number, are intended to allow the projection 1027 of the first tab 102, the projection 1038 of the second tab 103, a portion of the projection 1028 of the first tab 102 and a portion of the projection 1037 of the second tab 103 to be housed therein respectively. Thus, the projections, or the portions of projections extending over the entire width of the openings 10112 and 10112' may be located outside the portions of the openings which are intended to accommodate the hinge zones 1025, 1025', 1026, 1026', 1035, 1035', 1036 and 1036' of the two tabs 102 and 103. In this way, it is avoided that the hinges 3 manufactured from the pre-laminate according to the fifth embodiment of the first aspect of the invention have excess thicknesses extending across the width of the hinges, which would induce a loss of flexibility of the hinges 3.

[0111] On the other hand, it is observed that the system of stops previously described in relation to the other embodiments of the first aspect of the invention is reproduced through this fifth embodiment. Indeed, on the one hand each leg of the U-shaped protrusions constitutes a stop on one of the connecting edges 10111 of the board 101, on the other hand each bar-shaped protrusion intended to close a U-shape and the transverse bar of each U-shaped protrusion each constitute a stop on an inner edge of a connecting zone 1041, 1042, 1043. It will be noted, by observing FIG. 5D, that it is the latter which, relative to the cases illustrated in FIGS. 3D and 4D, are amputated by the opening extensions 10114. However, the connecting zones 1041, 1042 and 1043 again allow the fixing of each of the two tabs 102 and 103 on the board 101, for example using weld points 10411, 10412 and 10413.

[0112] In this fifth embodiment, the quantity of material located in the pre-laminate 100 at the hinge zones superimposed on each other in pairs is no longer distributed homogeneously; in other words, it is no longer constant regardless of the sub-zone considered. More material intended to form the hinges 3 is located in abutment against each connecting edge 10111 than there is material elsewhere. Thus, as illustrated in FIG. 5D, a hollow 10000 is provided between each pair of legs of each U-shaped protuberance. To return to the aforementioned example of a constitution of the tabs from a base layer and protuberances cut from another layer to be transferred onto the base layer, the hollow 10000 may have a depth substantially equal to the thickness of the layer from which the protuberances are cut. Furthermore, the 10000 hollow extends along the entire length of the hinge areas.

[0113] Thus, without losing the benefit of the stop system provided by each of the previously described embodiments, the fifth embodiment also makes it possible to reduce the material present at the hinge zones, to ultimately enable hinges 3 to be obtained that are of reduced thickness relative to the other previously described embodiments. This advantage will have the advantageous consequences, when inserting the data page into an identification booklet, of facilitating the sewing of the hinge to the rest of the booklet and improving the closing of the booklet.

[0114] It is observed that the first and second tabs 102 and 103 according to the fifth embodiment are strictly identical to each other, which facilitates their manufacture.

[0115] Note that the fifth embodiment of the first aspect of the invention is not limited to the above-described shapes of the protrusions, some U-shaped and others bar-shaped intended to close the U-shape of the first. For example, each protrusion of each tab could take an L-shape intended to each form half of the inner periphery of the openings, and therefore intended to form in pairs the entire inner periphery of the openings. However, if several protrusion shapes are conceivable, it is possible that some of them cause the first and second tabs 102 and 103 of the pre-laminate 100 according to the fifth embodiment to no longer be strictly identical to each other.

[0116] Other features of the fifth embodiment are deemed to be described through the description of the first, second, third and fourth embodiments and / or by any one of Figures 5A to 5D.

[0117] Figures 6A and 6B illustrate an implementation of the second aspect of the invention, relating to a method of manufacturing a data page 1, from a pre-laminate 100 according to the fourth embodiment of the first aspect of the invention, which is illustrated in Figure 4D.

[0118] Figure 6A illustrates more particularly an exploded sectional view of said pre-laminate 100 and of the front 22 and rear 23 faces of each data page 1. Note that it appears in Figure 6A that the front 22 and rear 23 faces of each data page do not cover, or only partially, the tabs 102 and 103; the partial overlapping of the front 22 and rear 23 faces may for example be limited to the overlapping of the overlapping zones of the tabs 102 and 103, but this overlapping cannot be total insofar as the flexibility properties of the hinge 3 would be lost. It also appears in Figure 6A that the connecting edge 10111 of the corelam zones 1011 intended to form the intermediate part 21 of the data sheet 2 are not necessarily straight, but may on the contrary show a shoulder for example sized to accommodate at least one overlapping zone of at least one of the two tabs 102 and 103.

[0119] Let us note here that the front 22 and rear 23 faces may consist of a single or several sheets superimposed on each other. In the example illustrated in FIGS. 6A, the front 22 face is illustrated as consisting of a single sheet, while the rear 23 face is illustrated as consisting of two sheets. For example, the front 22 face may be based on a transparent polycarbonate sheet with a thickness substantially equal to 100 microns and the rear 23 face may be based on the same sheet as that constituting the front 22 face on which is further attached a transparent polycarbonate sheet, possibly comprising a hologram, and with a thickness substantially equal to 75 microns.

[0120] The pre-laminate 100, the front face 22 of the data sheet 2 and the rear face 23 of the data sheet 2 are placed, in their relative position illustrated in FIG. 6A, between two lamination plates 201 and 202, in the manner illustrated in FIG. 6B, the front and rear faces of the data sheet 2 being in particular superimposed on each corelam zone 1011 which the pre-laminate 100 comprises and not covering the hinge zones 1021, 1022, 1031, 1032 of the first and second tabs 102, 103, to be hot pressed there.

[0121] It will be noted that at least one of the two lamination plates may comprise a bar 2011 extending along the tabs 102 and 103 when the pre-laminate 100 is located between the lamination plates 201 and 202.

[0122] If, in Figures 6A and 6B, the electronic chip 210, the antenna 220 and the transparent window 230 are illustrated only on one side of the pre-laminate 100, it is because Figures 6A and 6B are sectional views, and because, due to the head-to-tail arrangement of the pairs of corelam zones 1011 with each other, the electronic chip 210, the antenna 220 and the transparent window 230 housed in a first corelam zone 1011 of a pair is not necessarily visible in the sectional plane passing through the electronic chip 210, the antenna 220 and the transparent window 230 housed in the second corelam zone 1011 of the pair.

[0123] The result of the hot pressing as illustrated in Figure 6B is illustrated in Figure 7, which still represents a sectional view. It is observed that at least two hinges 3 have been manufactured, linked together at an axis 2010 along which they are intended to be separated from each other, and each linked to a data sheet 2; at least two data pages 1 have thus been manufactured. It is also observed that the hinge 3 has a thickness less than the thickness of the data sheet 2. Thus, in addition to having satisfactory tear resistance, the hinge 3 has characteristics enabling it to meet the specifications, in particular in terms of perfect closure of the identification booklet 0 in which the data page 1 is inserted and in terms of the ability to sew the hinge 3 to the rest of the identification booklet 0.

[0124] It goes without saying that the manufacturing method according to the second aspect of the invention does not only relate to the fourth embodiment of the first aspect of the invention used to illustrate the method through Figures 6A and 6B, but extends to the manufacturing of at least one data page 1 from any of the different previously described embodiments of the first aspect of the invention.

[0125] Moreover, Figures 6C and 6D illustrate an implementation of the second aspect of the invention from a pre-laminate 100 according to the fifth embodiment of the first aspect of the invention, which is illustrated in Figure 5D.

[0126] Compared to the example of implementation of the second aspect of the invention illustrated in Figures 6A and 6B, we find here, and in particular in Figure 6D, the hollow 10000 mentioned above.

[0127] A careful comparison of Figures 6B and 6D with each other shows that a difference between the two illustrated implementations lies in the fact that the bar 2012 illustrated in Figure 6D may have reduced dimensions, in thickness and / or in width, relative to the bar 2011 illustrated in Figure 6B. This difference makes it possible to take into account the fact that less material is provided to constitute the hinge(s) 3 according to the fifth embodiment of the first aspect of the invention.

[0128] Thus, each of the embodiments of the first aspect of the invention which are described above makes it possible, by implementing one of the embodiments of the second aspect of the invention described above, to reliably and easily obtain a data page 1 having: a. a hinge satisfactorily fixed to a data sheet, b. a hinge which is easy to sew to form the identification booklet, and c. a hinge which is sufficiently flexible to allow good closing of the identification booklet.

[0129] The pre-laminate 100 according to any one of the embodiments described above of the first aspect of the invention is adapted to the commercial problems encountered in the sector of activity linked to electronic passports and other identification booklets, in which several actors, sometimes geographically distant, are involved, some having capacities that others do not necessarily have and others having information, in particular personalization, which is not desirable to share. More particularly, as first parts of the data page produced by a first actor in the sector, pre-laminates 100 according to any one of the embodiments described above of the first aspect of the invention can be delivered to second actors who add to the parts provided other parts, possibly personalization, in order to finish manufacturing each data page.The pre-laminates according to the first aspect of the invention, although potentially specific (for example due to the shape of the transparent window 230 of the corelam zone 1011), are customizable and not yet personalized; typically, the customization data remains held solely by the second actor concerned by the delivery of the pre-laminates 100.

[0130] The invention is not limited to the embodiments previously described and extends to all embodiments covered by the claims.

[0131] In particular, it is not excluded that the protuberances are complementary to each other in their thickness in order, for example, to substantially match the thickness of the board 101, and more particularly of the corelam zones 1011; such protuberances would then preferably have a height, measured perpendicular to a main extension plane of the tongue, less than or substantially equal to half the thickness of the board 101.

[0132] Note that the fifth embodiment described above is entirely portable to other embodiments providing a pre-laminate according to the first aspect of the invention allowing the manufacture of only one hinge, or only two hinges. It is indeed envisaged for example that the protrusion 1027 illustrated in Figure 1 B does not extend over the entire width of the hinge zone 1021, and that the protrusions 1037 and 1038 illustrated in Figure 1 C do not extend over the hinge zone 1031, but from and beyond this zone, thus providing the first embodiment with the advantages of the fifth mode.

[0133] Let us also note some useful dimensions. The identification booklet typically has a height of 110 mm, maximum 125 mm. The dimensions of the board 101 and the tabs 102 and 103, including their sacrificial zones, are to be defined according to this constraint. For example, each sacrificial zone can extend in line with the corelam zone or the hinge zone with which it is associated over a distance of between 2 and 15 mm, preferably between 2 and 5 mm. Generally, each hinge has a width of between 2 and 15 mm, preferably between 2 and 5 mm, typically equal to 3 mm. If the data sheet has the same width as the pages of the identification booklet, typically 88 mm, then the data page will have a width typically equal to 93 mm with a hinge having a width of approximately 5 mm.Furthermore, the overlapping areas may typically have a width of between 1 and 10 mm, preferably between 1 and 5 mm, typically equal to 2 mm.
