- the band structure 24 may have a width greater than 4 mm, especially 5 mm, for example 20 mm.
- the windows 12 may have a width equal to that of the web structure 24, as illustrated in FIG. 14 or, alternatively, a width smaller than that of the web structure 24, as illustrated in FIG.
- the different windows 12 of the document 50 may have different colors.
- the letter A may appear in fluorescent yellow, the letter B in fluorescent red and the letter C in fluorescent blue.
- the different windows 12 may have different properties.
- the letter A may have "soft" magnetism properties, the letter B fluorescence properties and the letter C interferential effects.
- FIGS. 17 and 18 show a band structure 5 comprising, on one side, a plurality of main relief portions 56 serving to form each a main window on one face of the fibrous layer 5 and a plurality of raised portions additional 57 having a thickness and area smaller than those of the main relief portions 56 and arranged to compensate for a variation in thickness of the strip structure 55.
- the raised portions 57 are arranged, in the example considered, on either side of the raised portions 56.
- FIG. 19 shows a band structure 90 comprising a porous band support element 91 and an element 92 partially covering the band element 91 in order to create the raised portion 10.
- the element 91 is for example an element, preferably flat and not crenellated, which comprises openings 93 constituted for example by perforations.
- openings 93 extend, in the example considered, over substantially the entire surface of the element 91 other than under the element 92, the total section of the openings 93 representing for example more than 40%, better than 50% of the total area of the element 91, nevertheless being, for example, less than or equal to 60%.
- the presence of the apertures 93 facilitates the entanglement of the paper fibers and therefore allows for better anchoring of the web structure within the sheet material. This can also make it possible to use strip structures having a width for example greater than 5 mm, better still greater than 20 mm, for example of the order of 25 mm.
- each of the openings 93 is for example greater than 3 mm 2 and less than 30 mm 2 .
- the openings 93 are circular section holes whose diameter is preferably between 1 and 3 mm, especially close to 2 mm.
- the openings 93 can be made by perforation, for example by punching or punching.
- the areas of the support member 91 intended to be covered by the element or elements 92 may or may not include the openings 93, and preferably do not include them.
- the element 92 which creates the extra thickness is for example a deposit of a coating, for example one or more impressions of a varnish.
- the element 92 may further be an adhesive film which may be transferred cold or hot in the case of a heat-sealing adhesive.
- the excess thickness created by the element 92 is for example of the order of 10 to 50 microns, being preferably close to 30 microns.
- the element or elements 92 may be present only on one side of the strip element 91, but preferably the elements 92 are present on the two opposite faces of the element 91, being arranged facing two by two.
- FIG. 20 shows a sheet material whose fibrous layer 5 incorporates the strip structure 90, the element 91 flush with one face 14 of the fibrous layer 5, the outer face 97 of the element 92 flush with the opposite face 11 of the sheet material.
- the band structure may comprise, as illustrated in Figure 21, at least one cavity 99 housing an object 100 such as for example a chip of an RFID device or liquid crystal.
- the cavity 99 may be made in a porous band support element 91, for example having the characteristics described with reference to FIG. 19.
- the cavity 99 may extend in a zone of the element 91 which is covered by the elements 92 intended to create the extra thicknesses on the strip structure, these elements 92 then providing protection of the object 100 against external aggressions such as for example the mechanical stresses exerted during printing.
- the strip structure is for example embedded in the thickness of the fibrous layer 5, so that the element 91 does not flush on the faces 11 and 14, only the outer faces 97 elements 92 flush with these faces.
- the support member 91 is a knitted band, with large mesh.
- a strip structure with, on a first face, a crenellated strip element and on a second face opposite to the first, a coating of variable thickness defining raised portions.
- At least one of the raised portions may be formed by an electronic device fixed to a tape support element, this device comprising in particular an electronic chip.
- the raised portions of the web structure may be arranged to form detectable extra thicknesses on the two opposite faces of the fibrous layer.
- the sheet material may for example be used to make a packaging element such as a package.
