Definitions
- the present invention relates to an apparatus for manufacturing security paper or forgery-resistant paper and to the corresponding method.
- Background Art It is known that certain types of security papers (used typically to manufacture banknotes, checks, papers for identity documents or passports, etc) are provided with several security devices, which usually include a watermark and/or a security thread.
- Some kinds of forgery-resistant papers often have, in addition to the "classic" security devices mentioned above, additional security elements, constituted for example by so-called "plachettes", fibers, filaments having different shapes, sizes, or granules that can be fluorescent, luminescent, magnetic, magnetizable etc, having various dimensions, sometimes even on the order of 10 micrometers.
- These security elements are generally embedded within the sheet (at respective application regions) during its formation, by using feeder devices that are immersed in the forming box that contains the paper paste and within which the forming roller rotates.
- feeder devices are constituted generally by so-called “spreaders”, which are provided with an internal chamber connected, by means of an intake port, to a duct for feeding the security elements, which are usually diluted in water and are contained within a containment tank.
- the spreaders are further provided with a feeding opening, which faces a portion of the outer blanket of the roller, immersed in the forming box, so that the security elements that exit from the feeding opening can be deposited simultaneously with the paper paste onto the outer surface (wire) of the roller during the formation of the sheet.
- security paper manufacturing plants there is a collecting wire in order to allow the separation of the sheet from the wire of the forming roller.
- the sheet of paper formed on the rotating forming roller is transferred onto the collecting wire and contains all the security elements applied also with the aid of suction means, which produce an appropriate partial vacuum inside the forming roller.
- a forming roller or former which is arranged, along the paper production line, upstream of the forming roller (main watermarking roller), which in a manner substantially similar to what has been described for the forming roller forms a first layer, termed vellum, having a very fine grammage, which will be attached to the surface of the collecting wire (before said wire is arranged at the forming roller), and the wire itself deposits it on the second layer obtained on the forming roller.
- the two sheets while wet, then form a single so-called two-ply sheet.
- spreaders for depositing the security elements must currently be arranged so that they are more or less immersed in the forming box, and this causes drawbacks.
- the deposition of the security elements must be performed simultaneously with the deposition of a layer of paste on the forming roller.
- the spreader or spreaders must be properly adjusted and positioned at an appropriate depth within the forming box.
- this condition prevents monitoring (including visual monitoring) of the deposition of the security elements.
- any variation in the operating conditions within the forming box may determine a change in the conditions of deposition of the security elements
- the aim of the present invention is to provide an apparatus for manufacturing security paper provided with security elements that is capable of eliminating or in any case reducing drastically the drawbacks noted above in the devices currently in use.
- an object of the present invention is to provide an apparatus for manufacturing security paper that can offer high reliability in operation.
- Another object of the invention is to provide a method for manufacturing security paper that allows to obtain a security paper that can be printed easily.
- Another object of the present invention is to provide a method for manufacturing security paper that allows to control precisely and reliably the width, density and region of deposition of the security elements.
- an apparatus for manufacturing security paper according to the present invention comprising at least one main forming roller, which is provided with a lower portion or forming portion, which is arranged inside a forming box that contains the paper paste, and an upper portion or deposition portion, which is arranged below a collecting wire that can move along an advancement direction and is designed to receive, at a collecting face, the sheet formed on said forming roller, characterized in that it comprises a device for depositing security elements that is arranged upstream of the main forming roller along the advancement direction of the collecting wire and is adapted to deposit the security elements at the collecting face.
- the present invention provides a method for manufacturing security paper comprising the steps of: - depositing security elements at at least one deposition region defined on the collecting face of a collecting wire, - transferring, on top of said security elements, a layer of paper on said collecting wire.

- Figure 8 is a perspective view of a security paper provided with security elements
- Figure 9 is a view, similar to Figure 8, of a further embodiment.
- an apparatus for manufacturing security paper 200 comprises at least one main forming roller 2, which is provided with a lower or forming portion 3, arranged inside a first forming box 4, which contains the paper paste, and an upper or deposition portion 5, which is arranged below a collecting wire 6.
- the collecting wire 6 can move along an advancement direction (indicated by the arrow 100) and is designed to receive, at a collecting face 6a, the sheet 7 formed at the outer blanket of the main forming roller 2.
- the apparatus 1 is provided with a device 8 for depositing security elements 201, arranged upstream of the main forming roller 2 along the advancement direction 100 of the collecting wire 6.
- the deposition device 8 is adapted to deposit the security elements 201 at the collecting face 6a of the collecting wire 6.
- the apparatus 1 may have, upstream of the deposition device 8, a secondary forming roller or former 9, which is adapted to deposit on the collecting wire 6 (and particularly on its collecting face 6a) a vellum layer 10 of paper, so as to obtain a so-called two-ply security paper.
- the device 8 for depositing the security elements 201 is adapted to deposit the security elements at the vellum layer 10 conveyed by the collecting wire 6.
- the deposition device 8 comprises a supporting structure 11 for at least one feeder or spreader 12, which is arranged below the collecting wire 6 and has at least one intake port 12a, which is connected to a duct 12c for feeding the security elements 201, and at least one feeding opening 12b which, during use, substantially faces the collecting face 6a of the collecting wire 6.
- the feeding opening 12b has a substantially rectangular shape that is elongated along the advancement direction.
- the deposition device 8 can be constituted by a plurality of feeders 12, which are spaced along a direction that is substantially transverse to the advancement direction 100 of the collecting wire 6.
- the deposition device 8 comprises a suction device 13, which is arranged on the opposite side of the collecting wire 6 with respect to the feeder or feeders 12, and is provided with a suction or intake port that at least faces the feeding opening 12b.
- the deposition device 8 can be provided with at least one diffuser 14, which can be connected in output to each feeding duct 12c at a respective output manifold 15 and can be connected in input (at an input manifold 16) to a tank for containing an aqueous solution of the security elements 201.
- adjustment means are provided for adjusting the pressure of the solution inside the diffuser 14, so as to allow control of the flow-rate of the solution in output from the feeding opening or openings
- the adjustment means comprise a pump that is adapted to feed a mixture of the aqueous solution and air to the diffuser 14 by means of the input manifold 16.
- the diffuser 14 is provided with a discharge valve 17, which can be connected to a discharge duct that is connected to the containment tank, so as to be able to recover any aqueous solution of security elements.
- the present invention provides a method for manufacturing security paper comprising the steps of: - depositing security elements at at least one deposition region defined on the collecting face of a collecting wire; - transferring, on top of said security elements, a layer of paper on said collecting wire.
- the vellum layer 10 can have a grammage comprised between 10 and 25 g/m 2 , preferably comprised between 15 and 20 g/m 2 .
- the total grammage of the security paper, after the deposition of the second layer by the main forming roller 2, can be comprised between 60 and 120 g/m 2 , advantageously between 75 and 115 g/m 2 .
- an apparatus for manufacturing security paper is as follows. If two-ply security paper is to be produced, the secondary forming roller or former 9 deposits, on the collecting face 6a of the collecting wire 6, a vellum layer 10, on top of which the deposition device 8 deposits the security elements at respective deposition regions, which in the example shown and described earlier are arranged longitudinally with respect to the advancement direction of the collecting wire 6 and have a width (transverse dimension) that is substantially equal to (or slightly larger than) the width of the feeding opening 12b.
- the suction device 13 forces the adhesion of the security elements to the vellum layer 10, with consequent aspiration of the water and of any additives contained in the solution fed to the feeders 12.
