Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) In the following, the invention is explained in more detail with reference to figures illustrating an embodiment only. There are:

(2) FIG. 1a-e: a method according to the invention for producing a data sheet with introduced cover tab,

(3) FIG. 2a-e: an alternative method according to the invention for producing a data sheet with introduced cover tab,

(4) FIG. 3: a security and/or value document produced according to the invention.

DETAILED DESCRIPTION

(5) In FIG. 1 is shown a first alternative of the production according to the invention of a data sheet 5. Three layers 2, 3, 4 of a data sheet 5 formed from organic polymeric materials are brought together, wherein a layer 3 has smaller dimensions relative to at least one adjacent layer 2, 4 (FIG. 1a). In the example, layers 2, 4 consist of two layers 2a/b and 4a/b each. Bringing-together occurs with the proviso that the data sheet 5 forms a gap 7a or a step 7b along an edge 6, wherein the gap 7a or the step 7b is filled with an auxiliary piece 8 having a thickness, which substantially corresponds to the thickness D1 of the inner layer 3 of smaller dimensions (FIG. 1a). The auxiliary piece 8 is formed from a material which is not laminable with the layers 2, 3, 4. The stack thus obtained is subjected to a lamination step, wherein all layers 2, 3, 4 are laminated with each other, not however with the auxiliary piece 8 (1b). Lamination occurs by means of the lamination plates heated in a conventional manner and pressed with a given pressure against each other. After lamination, the auxiliary piece 8 is removed (1c). A data sheet region 9 of a cover tab 10 is introduced into the gap 7a of the data sheet 5 (1d) and is then connected with the data sheet 5 in a form-fit, force-fit, or material-fit manner, in the embodiment by means of sonotrode welding with the sonotrodes 15, 16. Finally, a cover region 11 of the cover tab 10 is bound into the cover 12 of the security and/or value document 1, for instance by means of sewing.

(6) In particular from FIGS. 1a to 1d can b e taken that the gap 7a preferably has a gap width which substantially corresponds to the thickness D2 of the data sheet region 9 of the cover tab 10.

(7) In the embodiment of FIG. 2, the procedure is quite analogous, except that there is no outer layer 4 and thus a step 7b is formed. Other than that, the above steps apply in an analogous manner, with the steps of FIGS. 2a to 2e corresponding to those of steps 1a to 1e. Basically, here are brought together just two layers (2, 3) of the data sheet (5), with the layer (3) of smaller dimensions being an outer layer and thereby step (7b) being formed. Step (7b) preferably has a step height, which substantially corresponds to the thickness D2 of the data sheet region (9) of the cover tab (10).

(8) In the two embodiments of FIGS. 1 and 2, the auxiliary piece (8) is formed from a coated plastic tape, the coating being formed from a material being incompatible with the material of the layers 2, 3, 4.

(9) Further, it can be taken from FIGS. 1 and 2 that the depth T of the gap (7a) or of the step (7b) has a value from 0.5 to 20 mm, in particular 1 to 10 mm, relative to the edge (6) of the data sheet (5).

(10) As an organic polymeric material for the layers 2, 3, 4, for instance PC (polycarbonate, in particular bisphenol A polycarbonate) may be used.

(11) As a material for the cover tab (10), for instance, a textile, a fabric, a woven fabric, a knitted fabric, a braid, a stitchbonded fabric, a non-woven fabric, a felt, an areal roving, a fiber network or an areal fiber arrangement may be used. The textile may be soaked with an organic binder, for instance based on PC (completely or just in the data sheet region 9), thereby the binder being thermally weldable and/or gluable with the material of a layer 2, 4 of the data sheet 5 overlapping with the cover tab 10. The binder may be cured before introducing into the gap 7a or the step 7b.

(12) In FIG. 3 can be seen that a data sheet 5 obtained according to one of FIG. 1 or 2 has been bound into a cover 12 of the security and/or value document 1.
