Description

The claimed group of inventions relates to the printing industry, namely to multilayer devices having double-sided lamination, namely to self-assembled multilayer devices with a double-sided lamination coating and to a method for their production, which makes it possible to obtain a protected multilayer product consisting of layers of materials of different properties without resorting to to the use of additional devices (laminators) with high precision of alignment of layers and bilateral protection of information from falsification in the interlayer spaces of the product.

There are different types of lamination using different types of laminators (http://printland.kiev.ua/blog/lamination.html).

For each type of product, a different method is applied.

Roll laminators are used to laminate products of A3 and larger formats. Lamination is carried out by rolling the object into a film fed from rolls located in the top and bottom of the laminator.

Another lamination method using a laminator is batch lamination.

Batch lamination involves the use of special blanks resembling envelopes, into which the product to be laminated is placed, then sealed using a sheet batch laminator.

However, such lamination does not provide high accuracy of alignment of layers in the package.

The technical result of the claimed group of inventions is to obtain a self-assembling multilayer device, with high precision of alignment of layers and bilateral protection of information from falsification in the interlayer spaces of the product, without the use of such auxiliary devices as laminators.

The main properties of multilayer products are: multicompleteness, multilayer, multifunctionality, printer suitability, security against counterfeiting.

The properties of the final product obtained from a self-assembled multilayer device are set at the time of completing the main carrier with auxiliary materials involved in the assembly of the self-assembled device.

Such end products can be securities, personal identifiers, shipping documents, passports and other valuable items, which, at the discretion of the issuer, are equipped with security elements.

To obtain the final product, it is necessary to prepare a blank for assembling a self-assembling multilayer device, which is then used in a method for producing a self-assembling multilayer device.

All layers in a workpiece for a self-assembled multilayer device are processed using a cutting tool that sets the depth of layer-by-layer punching and determines the shape of each layer, depending on the properties laid down in the product.

The maximum and minimum size of the preform for a self-assembly multilayer device is limited only by the formats of consumables.

Each assembly step reduces the original stock size by a multiple of the number of fold perforations.

The claimed self-assembled multilayer device has a high degree of protection against reproduction and copying.

The use of elements of protection against reproduction and copying allows you to verify the authenticity of the information carrier, and the elements themselves simultaneously serve as its protection against counterfeiting and forgery.

Structurally, the declared device can be used for all types of ZPP (protected printing products), wherever reliable protection of information is required, for example, details, etc.

A blank for a self-assembled multilayer device can be sealed with any type of printing device. Limitations mainly related to the size of the gap between the printing element and the sheet transfer system can only be determined by the type of printing device itself. The printed information is reliably protected by a transparent laminate that is applied on both sides of the product.

In general, a blank for a self-assembled multilayer device with double-sided information protection against falsification includes a rectangular base, with lamination windows located one above the other, with layers placed inside, folding perforation under each lamination window.

In the two upper windows for lamination, there are bearing information layers, with molding notches applied to them, on the reverse side of each of the bearing information layers adjacent to the surface of the workpiece, an adhesive coating is applied, separated from the base by a protective layer, and in the two lower windows there are laminating transparent layers with molding notches applied to them and an adhesive coating located on the front side of each laminating transparent layer and covered with a protective layer.

The characteristics of the final products, set by self-assembly multilayer devices, depend on the properties of the materials that make up the workpiece.

The workpiece can be completed with polymeric materials with various physical and chemical properties, materials from a paper base, metal foil materials. The special properties of the final product are given by the insert, which is glued into the interlayer space of the claimed device.

The insert is a multilayer plastic device made using the technology of plastic cards production. The insert contains layers of polymer material (for example, polyvinyl chloride or polycarbonate), the properties of which will determine the strength characteristics of the product. If the insert is made using the technology of production of contactless cards, then the declared device will receive the properties of a contactless card that operates over a radio channel without additional power sources inside the device.

Thus, the insert can enable the self-assembled multilayer device to communicate over the air using RFID tags of various wavelength ranges.

The shape of the final product can vary over a wide range. A limitation on the shape of the product can only be imposed by the complexity in the manufacture of the cutting tool, otherwise the product can take any geometric shape.

For exceptional protection of the final product, printing under a transparent lamination layer on the carrier layer can be performed using security printing elements, including a printed layer, which can also be protected by the presence of watermarks, special security threads distributed throughout the mass of the material.

Depending on the type of materials used and the number of security elements, the product can be assigned a security category assigned in accordance with the current version of the Order of the Ministry of Finance regulating the release of security printed products (hereinafter referred to as the RFP).

In general, the claimed self-assembly multilayer device is made as follows.

The self-assembled multilayer device includes an insert made in the form of a multilayer plastic product with or without a radio frequency tag, aligned on both sides with carrier information layers, laminating transparent layers located on the outer sides of the self-assembled multilayer device and aligned with the carrier information layers.

The method of obtaining the claimed self-assembled multilayer device with two-sided information protection against falsification using a blank for a self-assembled multilayer device in general is as follows.

First, a protective layer covering the adhesive coating located on the front side of each laminating transparent layer is removed on the workpiece, then the workpiece is folded along the center line of the fold perforation located in the middle, combining the carrier information layers placed in the workpiece in the two upper lamination windows, with laminating transparent layers located in the workpiece in the two lower lamination windows and attaching the carrier information layers to the laminating transparent layers by means of an adhesive coating located on the front side of each laminating transparent layer.

After that, the workpiece is laid out along the center line of the fold perforation, with the formation in the upper windows for lamination of bed elements with a protective layer peeled off from the back side of the carrier information layer, then an insert made in the form of a multilayer plastic product is placed in one of the bed elements to improve the strength of the finished product. radio frequency tag or without it, the size of which is the same size as the carrier information layer or less.

The workpiece is again folded along the centerline of the fold perforation, after fixing the insert on the adhesive coating of one of the carrier information layers fixed to one of the laminating transparent layers located in the lower lamination windows, the workpiece is again laid out along the centerline of the fold perforation. The preform is then torn at the midline of the transverse fold perforation, removing the top of the preform with the two upper lamination windows.

The rest of the blank with two lower lamination windows is folded along the centerline of the fold perforation, aligning one part of the self-assembling multilayer device located in one of the lower lamination windows and made of a carrier information layer attached to the laminating transparent layer with the other part of the self-assembling multilayer device , located in another lower window for lamination and made of the inserts fixed to each other and the carrier information layer fixed on the laminating transparent layer, fasten both parts of the self-assembled multilayer device, with the subsequent extraction of the finished product along the molding notches applied to the carrier information layers and laminating transparent layers.

To obtain a self-assembled multilayer device, it is necessary to prepare the workpiece in a special way. To do this, it is necessary to determine the material of the carrier information layer, the properties of which will largely determine the characteristics of the final product.

An image is embedded in the carrier information layer (1), which is to be further protected by transparent laminating layers. Watermarked paper containing security threads with various security properties can be used as the carrier layer. In the case of using any elements of the RFP, the device can be classified as protected printed products in accordance with the current version of the Order of the Ministry of Finance regulating the production of protected printed products.

Layer 3 and Layer 4 are sequentially applied to the carrier information layer by cold or hot rolling.

Layer 3 - serves as a separating layer between the carrier information layer 1 and the transparent laminating layer 4. This layer is made of polymer material of various thicknesses, as a rule, its thickness should not exceed the thickness of the laminating layer 4 and be at least 15 microns. The thickness of the layer is taken into account when developing the design of the chipping knife.

Layer 4 - serves as a laminating transparent layer with specified properties. On the side facing layer 5, an adhesive coating is applied, which ensures the bonding of layers 4 and 1 after lamination.

As an alternative technology, these layers 4 and 1 can be pre-rolled to each other prior to rolling onto the carrier information layer. Both methods are considered to be equivalent technologies. Each of the above layers performs its function determined by the order of the layer in the structure shown in figure 1.

Layer 2 - performs a protective function aimed at protecting the properties of the adhesive coating of layer 1 until the moment of lamination of layer 1 with layer 4 (after folding) or layer 1 with insert (6) and is a barrier between the base and the adhesive coating of layer 1.

Layer 1 is a carrier information layer that defines the main properties of the product. The layer is made of polymeric material, or of paper, including all types of paper, the thickness of which is in the range from 10 to 1000 microns. The layer bears forming notches and an adhesive coating covering the entire area defined by the shape of the chipper.

By performing the sequence of actions indicated below for the assembly of the self-assembled multilayer device, layer 4 protects information (for example, details) placed on the carrier information layer 1 from moisture and falsification.

This layer 4 is made of a polymer material of various thicknesses with or without a holographic image. The layer thickness is determined by the physical characteristics of the claimed device and ranges from 10 to 300 microns. The thickness of the layer is taken into account when developing the design of the chipping knife. The layer bears a molding notch.

Layer 5 - performs a covering function aimed at protecting the properties of the adhesive coating of layer 4 until lamination with layer 1.

Box 6 is a special product that determines the physical-mechanical and radio-electronic properties of the claimed self-assembly device.

The sequence of steps for assembling the declared self-assembly device is as follows:

1. The protective coating (layer 5) is removed from the surface of the windows for lamination, revealing the adhesive coating of layers 4 (Fig. 3).

2. The device is folded along the centerline of the fold perforation until full contact in the lamination windows of the front surface of layers 1 and the surface of layers 4, on which an adhesive coating is applied (Fig. 4).

3. The device is laid out along the midline of the fold perforation, while layers 1 are transferred to the adhesive coating of layers 4. In the lamination windows in the upper part of the workpiece, where layers 1 were previously placed, lodgements are formed in the form of a lamination window, with layer 2 remaining in them.

4. In any of the lodgments on layer 2, an insert 6 is placed, in shape being an exact copy of layer 1 or less (Fig. 5).

5. The device is re-folded along the midline of the fold perforation to transpose the insert 6 into the lamination window, in which the interconnected layers 1 and 4 are located, strictly in the position according to the shape of layer 1 (Fig. 6).

6. The device unfolds along the center line of the fold perforation, leaving the glued-in insert 6 in the lamination window at the bottom of the workpiece.

7. The device is torn in two along the midline of the fold perforation (FIG. 7).

8. The device is folded along the longitudinal line of the fold perforation (Fig. 8).

The insert becomes the middle connecting layer of the product. Description of drawings.
