RO131258B1 - Ceramic tile display system - Google Patents

Description

The invention relates to a system of exposing ceramic tiles, intended for exhibition purposes, a method of obtaining it, as well as a method of arranging ceramic tiles on the surface of the panel.

Exposure panels of ceramic tiles are commonly known, which are usually represented by metal structures that support agglomerated or fibrous wood panels / medium density pallets or ultra-light panels bearing the manufacturer's logo, a sample image, as well as the indication of the plate collection. ceramics and some samples of ceramic tiles.

In this field, the exhibits of panels made of fibrous wood / medium density pallets, of agglomerated plates, light panels, of cardboard or other similar products, based on panel, are known for exhibition purposes. Branding / marking for these types of panels is done by gluing a sheet printed on the panel, and ceramic tiles or products intended for exhibition are usually glued with soldering gun or self-adhesive tape.

Whenever the collection of ceramic tiles is changed or only one plate in the collection, the manufacturer will update all previously delivered panels at various points of sale on the market, so that, for example, old panels with the collection are withdrawn from the showrooms. of ceramic tiles affixed to them, new wood-based panels are purchased, marked with the manufacturer's logo, the ceramic tiles are applied to these panels with permanent adhesive, and the packages for delivery to the distribution channels are suitably prepared. This process is very costly and represents one of the major costs that the ceramic tile manufacturer covers from its marketing budget, because the process not only involves the costs of purchasing the new panels, but also the adjacent costs for storage, transport, logistics, packaging, recycling of the disassembled panels and so on. Also, the installation process of the panels affects the normal activity of the trading points, and involves difficult handling procedures, during which some ceramic tiles can be broken.

From the document of the state of the art EP 2853179 A1 there is known a system of exposure with rapid change and installation for planar elements thereof, that is, a system provided with a surface capable of easily exposing planar elements of interest, in which this surface of exposure is endowed with a distributed magnetic field, and made of a layer of material made of rubber or synthetic plastic equipped with ferromagnetic material dispersion, activated to create the aforementioned magnetic field; each planar element or the like is provided with at least one attachment means applied by means of an adhesive layer on the support face of the planar element of interest, and includes dispersion or ferromagnetic continuity of the material.

The panel described above has the disadvantage that it is far too heavy, even in the absence of glued ceramic tiles, which makes it unusable for classic metal frame displays, as they are not designed to support such an additional weight. In addition, high-weight ceramic plates need significant magnetic force to hold these markings upright on the panel. Another significant disadvantage of the patent application EP 2853179 A1 is that the system is provided with a thin material layer between the parts to be supported, for example the plates, and the magnetic rubber layer. This significantly reduces the friction between metal and rubber, and reduces the magnetic field. Therefore, the system can not support heavy ceramic plates that have more than 20 kg / m ² because of heavy plates will interact directly with the thin sheet photographic material, which will reduce the friction.

In addition, the method used in the prior art to customize, namely, direct printing 1 on a roll that completely covers the panel is not financially effective, compared to the solution presented in this application. 3

Also, the state of the art does not offer complete solutions for assembly or disassembly, the removal of magnetized plates is not easy after 5 have been exposed for a long time. In addition, the arrangement of the new ceramic tiles is difficult to execute unless a special template / pattern is designed for this operation.

GB 2255433 A is also known, which refers to a panel 1 made of 9 plastic, wood or substitute wood material, on which a foil 3 of a ferromagnetic material is fixed with adhesive, on which letters, figures can be fixed. or other 11 presentation / advertising materials 4, made from a magnetic foil of a flexible synthetic material, as well as some means for aligning these letters. 13

Also known from US 3634797 is a display panel 10, which comprises a support 12 provided with magnetic zones for gluing a display element 15 14 (foil), provided with magnetic or magnetized areas, representing an advertising product.

The technical problem solved by the present invention consists in obtaining a ferromagnetic panel 17 for the exposure of ceramic tiles to ensure increased stability of the exposed products, as well as a quick and easy replacement. 19

The ceramic plate display system, according to the invention, removes the disadvantages of the other systems by the fact that the metal sheet is provided on the opposite side of the panel with an adhesive paint layer 21, and the respective update kit contains at least one self-adhesive magnetic sheet for each subsequent reference. to be exposed, and a 23 disassembly tool.

The method of obtaining the panel for the ceramic plate display system, 25 according to the invention, removes the disadvantages of the known methods by comprising the following steps applied on at least one surface of the base panel: 27

a) feeding the base panel into the feed device;

b) the roll, from a roller, of a thin metal sheet previously covered on one side with an adhesive paint layer, and the application of an adhesive layer on the side from the base panel, with a speed that is between the feed rate of the roll of the roll of the sheet metal and the speed of curing of the adhesive, where the base panel and the sheet of metal of the roll are centered using the guide rollers; 33

c) pressing the metal sheet over the base panel, at room temperature.

The method of arranging the ceramic tiles on the surface of the panel, according to the invention, 35 removes the disadvantages of the known methods in that it will contain the steps:

- fixing a template on the panel starting from the bottom, by centering it on the metal structure 37 which supports the panel;

- arranging the first row of plates by guiding them in the respective templates; 39

- removing the template from the first line; fastening the template above the last row of plates, formed by centering with the upper edge of the last row of plates;

- arranging the plates by guiding them in the respective templates;

- removing the templates.43

The adhesion of the ceramic plates on the surface of the panel is strong enough to prevent them from detaching when the panel is upright.45

Therefore, this invention provides a ceramic tile display system consisting of: 47

- a base panel, with a thin sheet of metal, applied to one or both sides by means of an adhesive layer that sticks the sheet of thin metal, this sheet 49 of metal being provided on the opposite side of the panel with a layer of non-stick paint, and

RO 131258 Β1

- a replacement kit, which contains at least one self-adhesive magnetic foil for each part to be exposed, and, optionally, a tool for disassembly.

The non-stick paint layer is characterized by the presence of a succession of layers, for example, polyethylene, as a protective layer, acrylics, as a top coat, polyester, as a primer layer, as a chromium, as a chemical layer, and as a coating on the inner face. element 4, usually polyethylene.

If the base panel has only one side adhesive layer, a melamine balancing layer on the other side of the panel may optionally be attached to reduce the stresses caused by attaching an additional element to only one side of the panel. Basic.

Also, the upgrade kit may also contain a printed magnetic imprint of the brand, produced in accordance with customer requirements, and / or an intuitive modular template, along with a set of instructions for quickly and accurately arranging updated plates. The printed magnetic inscription can be, for example, an isotropic or anisotropic magnetic foil, with a self-adhesive printable foil or sticker directly attached to it, with a thickness between 0.2 and 0.8 mm. The self-adhesive magnetic sheet for each part to be exposed can be isotropic and can have a thickness between 0.5 mm and 2 mm.

The tool for disassembly is metallic, having the upper part in the form of a u and capable of supporting a landmark. The profile fins in 'u are thin, so one of the fins can easily reach below the mark, and can detach it with a short upward movement.

The upgrade kit can include multiple engraving positions, multiple shapes, and self-adhesive magnetic sheets are sized (as tensile strength and surface tension) to support any type of plate requested by the customer. Additionally, the base panel is available in various thicknesses, shapes and sizes, as presented above, to fit any metal frame display. This creates a major economic and logistical advantage for the customer, when implementing the product, because it does not present the need to change the exhibitors on metal frame that are already located in the points of sale.

The panel system can be optimized with other attractive features that include a magnetic brochure holder, magnetic tag indicators for each ceramic plate, detachable promotional messages. Various other features, uses and designs of the panel system can be put into practice to meet the client's utility or aesthetic requirements. For example, if the panel base plate is to be weather resistant, such as the HPL plate, the panel may be used outside to expose ceramic tiles that will be used outdoors (wall cladding). , clinker, pool wall plates).

The ceramic plates applied in this innovative way benefit not only from the magnetism created between the ferromagnetic base plate and the magnetic base of the ceramic plates, but also from the friction that appears between the two surfaces. The rubbing was optimized by using the special adhesive paint layer applied to the base panel.

Another problem that this solution answers is the creation of a more sustainable and recyclable product, which reduces the wood consumption required for the panel updating process by more than 80%. This saving of consumption comes from the fact that the panels will not change every time a collection is updated, because the panels are first installed, and only afterwards the ceramic plates and the graphic signs are changed. The replaced materials are complete

EN 131258 Β1 replacing the decorative elements of the walls with other elements that change 1 presentation by attaching with magnetic material applied with adhesives even the decorative element is a method known in the art, and can serve as a basis for the present 3 invention. However, the present invention does not refer to a universal fixing system, but to a complete solution, designed and intended for the process of exposing ceramic tiles to panels, 5 which provides for the specific features that arise during this process - such as, for example , the inscription of the panel, the correct placement of the ceramic plates by using a 7 special innovative template, the use of various types of ceramic plates and their support, the shocks suffered by the panels during the execution, transport and life cycle, the 9 production methods, etc.

The solution proposed by the present invention ensures not only the changing of ceramic tiles 11 which are updated, but also the complete updating of the display panel with new graphics, which accompanies the new ceramic tiles. 13 In addition, the current solution is a solution to various problems that arise from the process of panel production. For example, when the supplier has to update a large collection of 15 ceramic tiles and uses the technique known in the art, a process that can take months, the manufacturer can remove / remove / remove from the list some 17 of the items (stock items). ) for various reasons (supply of raw materials, poor performance of the product when tested on the market, etc.). In this case, if a single stock unit from a collection is removed from the list, then the entire panel must be changed, even if the other samples are still available. Also, if, for whatever reason, a panel 21 constructed by the technique known in the art reaches the market with an unsatisfactory composition, the solution to remedy this mistake is to completely change the entire panel. A limit 23 known in the art is also that the seller cannot create a certain composition with a collection consisting of the best-selling items of the season to be run, but 25 must order a certain composition of the panel from the supplier. It is also known that the display panels are manufactured and delivered at the points of sale by the 27 ceramic tile manufacturers directly. Therefore, the trader currently has a single-panel exposure limit of a composition of ceramic tiles provided by 29 different manufacturers. In addition, the trader cannot submit limited-time exhibition space offers on a panel, as he would like, because he has to order a particular panel for each of the ceramic products sent by the factory.

The system presented by the invention is an alternative to the classic exposure system through 33 panels; according to the new system, updating a collection or changing in any way the ceramic tiles already displayed on the panel no longer requires changing the entire ceramic display panel. The customer initially receives the system consisting of a single panel cut to size in accordance with the existing metal structure, the panel is delivered empty, together with 37 with the first upgrade kit, which he will fix on the ceramic plates. In this way, the ceramic tiles can be magnetically fixed to the hollow panel. The system is specifically defined by the use of extremely heavy products, which it is intended to keep upright. A ceramic plate can reach up to 20 kg in weight. 41

As noted above, the process of replacing the panel at points of sale represents a major cost, which affects the marketing budget of a 43 ceramic tile manufacturer. Therefore, there is an apparent need to find a solution that will reduce costs, time and storage space, and that will require at least 45 trading points when upgrading. There is also a need for ceramic manufacturers, but also the outlets to replace even a single piece of ceramic plate 47 if that plate is not in compliance or does not sell well. in addition, it appears

EN 131258 Β1 the need to display promotional messages on the panel in a simple, hassle-free manner, allowing easy return to the initial state of the panel. For example, it is the case of the "newly arrived" or "sale" items. All these disadvantages are solved by the system of the present invention. Also, the presented system is environmentally friendly because the consumption of chipboard or MDF panels is reduced by more than 80% through this system.

The proposed system of the invention is used, preferably, in specialized stores for the display of ceramic tiles, but also in DIY stores, showrooms, etc. The system can also be used when displaying products at fairs, when a fair stand recreates the framework of a ceramic tile showroom.

In addition to ensuring better utility and ease of use, the system can also be used in exhibition spaces with various configurations, such as, for example, a stand-alone panel, a partition wall, or as cladding layers. which can then be applied to different environmental ceramic tiles (1: 1 scale).

The system also has the possibility to satisfy the user's aesthetic tastes and needs. In this regard, the coating layer of the panel may be in various colors, or a permanent (or equivalent) silkscreen print may be added. These beneficial aspects included in the applications of the present invention, as well as other advantageous features will be described below.

In another embodiment of the invention, there is provided a method of obtaining a ready-to-use panel for the exhibition, a method consisting of the following steps:

a) feed the base panel with adhesive layer on one side, in a feed device provided with means for scrolling the metal sheet with a speed between the speed of roll of the sheet of metal sheet and the rate of hardening of the adhesive;

b) the metal sheet is rolled over the base panel, where the base panel and the sheet metal roller are centered by means of the guide rollers;

c) press the metal sheet over the base panel at room temperature;

d) the steps from points (a) to (c) are optionally applied to the second surface of the base panel.

In another embodiment of the invention, there is provided a method for arranging the ceramic tiles on a base panel as the one obtained above, a method consisting of the following steps:

- a template is fixed on the panel starting from the bottom, by centering it on the metal structure that supports the panel;

- the first row of plates is arranged by guiding them in the mentioned patterns, the template from the first row is removed;

- the guide template is fixed above the last row of plates formed by centering it with the help of the upper edge of the last row of plates;

- the plates are arranged by guiding them into templates;

- the templates are removed.

For a better understanding of the present invention and the advantages resulting from its various applications, we will describe it further by means of preferred embodiments of the invention, without limitation, referring to them in the description of the attached drawings.

Referring to the attached drawings, fig. 1 shows a classic exposure panel 1, known 23 in the art as having ceramic plates 10 bonded to it with ceramic adhesive 11, as can be seen in section A-A, detail B. Section A shows a section through the finished panel 25. Also, FIG. 1a and FIG. 1b illustrates the exposure of the panel inscription (graphic / photo). Graphic element 15 is either printed on a sticker and then rolled on 27 panels, or printed directly on the panel. Fig. 1 provides a better understanding of the technological challenges to which the present invention responds. The panel built according to the classical method is practically a block of materials joined by permanent adhesives, and is devoid of any modularity. 31 in addition, for a better understanding, fig. 2 presents the process of replacing a classic panel built on an exhibitor with an existing metal frame. Fig. 2a illustrates an exhibitor with classic metal frame, FIG. 2b, FIG. 2c and FIG. 2d shows the assembly of a classic panel on a metallic structure. The disassembly of the panel on the frame of the exhibitor clearly shows 35 and from fig. 2, this operation is usually performed by at least two qualified persons, equipped with tools. 37

Fig. 3 represents a panel P according to the invention, which will be used together with the upgrade kit. Panel P contains the base panel 2, usually made of chipboard 39 or of medium density fibers, the adhesive layer 3 is used for bonding the thin metal sheet 4 to the base panel 2, and a thin layer 4 is applied to the thin metal sheet 4. 41 special adhesive paint 5.

Fig. 4 shows a cross section through the panel which is in accordance with this invention. The panel of the invention has two applications. Fig. 4a shows a one-sided panel, where the thin metal sheet 4 is applied only on one side of the panel. Fig. 4b shows a 45 double sided panel, where the thin metal sheet 4 is applied on both sides of the base panel 2. The embodiment representing the single sided panel comprises a 47 panel.

EN 131258 Β1 base 2, an adhesive layer 3, a thin metal sheet 4, a layer of adhesive paint 5 and a layer of melamine or balance paper or other similar material, respectively, a balancing layer 6, provided on the opposite side of thin metal sheets 4. The embodiment which represents the two-sided panel does not contain layer 6, it having only two sequences of layers 3, 4 and 5 which have been defined above.

Fig. 5 shows an example of the placement of the magnetic self-adhesive sheets 12 on the ceramic plates 10. Depending on the characteristics of the ceramic plates, especially the thickness, weight, pattern on the back of the ceramic plate, various combinations, assemblies and types of magnetic sheets can be used.

Fig. 6 is a perspective view of the new panel system P with all the components installed, namely, the base panel 2, the adhesive layer 3 used for fastening the thin metal sheet 4, covered with the adhesive paint layer 5, the ready-made ceramic plates 10 and an example of the customer's trademark attachment, printed on a magnetic foil 16.

According to the illustration in FIG. 7, components 10 and 16 are part of the upgrade kit which also contains a custom-made mounting template 14 for easy placement of the ceramic plates 10 on the panel, as well as a tool 13 for disassembling the plates. The upgrade kit comes in a box. In one application, the kit does not include ceramic tiles because they can be delivered separately. In addition, FIG. 7 shows the back of the ceramic plates after mounting the self-adhesive magnetic sheet 12 in the upgrade kit. The magnetic foil has a self-adhesive face which, depending on the back of the ceramic plate, can self-level or not (in this case a thick / spongy self-adhesive is used).

The placement of the ceramic plates 10 referred to on panel P is described in fig. 8; the intuitive modular template 14 is used for the quick and correct arrangement of the ceramic tiles.

The upgrade kit is provided with instructions and, thus, even a non-qualified person can assemble the ceramic plates 10 and the magnetic inscription printed 16 on the panel P. The modular template 14 is magnetic, and fig. 8 shows that the starting point is always chosen from the bottom of the panel. As mentioned, the modular template 14 is designed and cut to match ceramic tiles. in FIG. 8b, the modular template 14 is centered by means of the metal frame, and the first ceramic plate 10 is thus placed. The first row of plates will be used as a mounting bracket for the top plates, as shown in fig. 8d, 8e and 8f. Fig. 8d, 8e, 8f, 8g and 8h show various types of ceramic plates 10 which are arranged using modular template 14. This example shows the ease of use of this method of laying ceramic tiles. Fig. 8i shows how to apply on the panel P the printed magnetic inscription 16, delivered in the box with the rest of the kit. The inscription runs simply on the designated part of the panel. Fig. 8j shows the disassembly of the printed magnetic inscription 16, and fig. 8k shows the panel after the printed magnetic imprint 16 has been removed. The plates are disassembled from the panel P by the use of a special tool which is fastened under the ceramic plate 10, and provides a suitable attachment.

Fig. 9 presents the technological process of execution of the panel based on wood with a thin metal sheet 4. Higher productivity and good quality can be obtained by using this production method, by the direct roll press method. Thus, FIG. 9 shows a wooden base panel 2 (can be made of chipboard or fibrous wood board) which is loaded manually or automatically onto the transport roller 20. The wood plates are aligned by the guide rollers 22, and are moved by the rollers feed 21. on the top and bottom of the drawing are presented the thin sheet metal rolls 4, previously covered with a layer

RO 131258 Β1 special adhesive paint, rollers that are mounted on the roller feed mechanism. As the thin metal sheet progresses, it is covered with a two-component adhesive 3 by an adhesive stretching system by oscillation 24. When the panel and the thin metal sheet 3 reach the tread, they are aligned and pre-pressed by the alignment rollers 23, and afterwards are pressed by the pressing rollers 25. further, the panels are cut to 5 the length desired by a movable circular sheet 26. The final result is panel P which is ready for use for the purpose of exposing the ceramic plates. The bottom of FIG. 9 shows method 7 of producing a two-sided panel, describing the same system of advancement and stretching of the adhesive as the one represented at the top. In the case of a two-sided panel, 9 the system represented under the base panel 2 is activated (4 and 24 at the bottom of the figure).

Particularities of system components 11

First of all, we want to emphasize that panel P can be delivered in different thicknesses, usually from 3 mm to 40 mm, depending on the application. Typically, on exhibitors with 13 metal structures, the preferred embodiments are 10 mm, 16 mm and 18 mm thick. Panel P contains, as shown in FIG. 3 and 4, a sequence of layers that are 15 each important. Base panel 2 is usually made of a wooden base plate, such as, for example, particle board, medium density fiber or wood fiber board 17 oriented - the most common being the wood chipboard. Other types of rigid plates, for example, polystyrene or cardboard, or honeycomb cardboard, light plate and so on can be used. The base panel 2 has a length ranging from 400 mm to 3000 mm, a width from 150 mm to 2100 mm and a thickness from 3 mm to 40 mm. The example of 21 preferred embodiment to be used in metal structure display units is a base panel 2 with a thickness between 6 mm and 20 mm, a width between 600 mm and 1100 mm, and a length 23 between 1300 mm and up to 2200 mm. . In other embodiments, the panel P may also be produced as a flexible panel to support the mosaic tiles. 25

The adhesive layer 3 is the adhesive applied for fixing the thin metal sheet

4. In a preferred embodiment, the adhesive layer 3 is a two-component adhesive with fast curing time 27, which begins the curing process when the base panel 2 contacts the thin metal sheet 4. The single-component adhesive may also be used. . The peculiarity 29 of this adhesive is that it can glue a sheet of metal to the base panel 2 having the characteristics described above. The special sheet of galvanized metal 4 has a special feature a thickness of 31 ranging between 0.1 mm and 2 mm. In a preferred embodiment, the thickness of the thin metal sheet 4 is between 0.1 mm and up to 0.8 mm, especially depending on the base 33 support and the desired application. The best application indicates that the thin metal sheet 4 varies between 0.18 mm and 0.4 mm, with optimum weight / performance results on a 35 sheet.

0.25 mm. Usually, the thin metal sheet 4 has the same width as the base panel 2 in any of the applications. The length of the thin metal sheet 4 is cut to a dimension of a roller 37 by the device with circular movable blade 26.

A key element of panel P is the non-slip (adherent) paint layer 5, 39 which is characterized by a succession of layers such as, for example, polyethylene for the protective layer, acrylic for the top layer, polyester as a primer layer, chromium as a layer. 41 chemically, and a coating of the inner face on element 4, usually polyethylene. In a preferred embodiment, the non-slip paint coating 5 adheres to the following 43 layer thicknesses: 50 µm polyethylene as a protective layer, 7 ± 2 µm acrylic paint, 15 ± 2 µm polyester paint, 1 µm chrome as chemical layer, 5 ± 2 pm layer 45 PE support. The gloss of the non-slip (adherent) paint layer 5 in a preferred embodiment is 85 ± 10, but the paint layer may also be matte (below 40 ± 10), 47 due to the adhesive properties of the film.

RO 131258 Β1

The element 6 is a balancing material on the back of the base panel 2, intended to release the stresses caused by the attachment of an additional element only to one of the parts of the basic panel 2. The layer of balancing material 6 has the same surface as the metal sheet. thin, and is a feature of the metal panel with one side. An adhesive coat of paint 5 will be added automatically in the case of panel P with metallic face and two sides.

The layer 16 represents the characteristic marks of the client, namely, his mark placed on the panel, named in the description of the present invention as printed magnetic inscription. This does not have certain size characteristics because the branding is done in accordance with the client's design / sketch, in any shape or color desired. Element 16 is a magnetic foil having a printable or self-adhesive sticker foil. The sticker can be printed separately, with a classic printing machine, and then laminated with a classic laminating machine, on the magnetic foil. The magnetic foil does not have to be self-adhesive. The other option for item 16 is to be made from a magnetic foil delivered with printable foil attached, and printed directly on the magnetic roller. The printed magnetic branding 16 is characterized by the fact that it is an isotropic or anisotropic magnetic foil, having a thickness between 0.2 and 0.8 mm. In a preferred embodiment, the film thickness is between 0.3 mm and 0.5 mm. The printed magnetic marking 16 can be cut with a laser cutting machine, or with an oscillating knife machine. Simple cuts will be done manually or with guillotine. In one embodiment, the printed magnetic branding 16 must completely cover panel P, while in other applications, where ceramic plates 10 with self-adhesive magnetic foil 12 come in contact with panel P, it is recommended to perform hidden cuts in the branding. magnetically printed 16, so that the self-adhesive magnetic sheet 12 comes in direct contact with the panel P.

The ceramic plates 10 are attached to the panel P with self-adhesive magnetic sheet 12. The dimensions of the self-adhesive magnetic sheet 12 are calculated according to the characteristics of the ceramic plates 10. The two major factors influencing the self-adhesive magnetic sheet 12 in relation to the ceramic plates 10 are the weight and the dimensions. of the ceramic plates 10, as well as the pattern on the back of these ceramic plates 10. depending on the back of the ceramic plate 10, a suitable self-adhesive solution will be used for the element 12. Thus, if the back of the ceramic plate 10 has irregularities and a pattern with pattern high, then apply a self-adhesive foam foil with self-leveling on the back of the self-adhesive magnetic sheet 12. If the inner face of the ceramic plate 10 is smoother, apply a self-adhesive foil without foam. This is an important problem because, if the pattern relief on the back of the ceramic plate 10 is high, the self-adhesive magnetic sheet 12 will copy the model and, in this way, the force of the respective element 12 will decrease by contact with the panel P only where the relief it is high, but it will not touch the panel where the relief is down. It is known that between the P-panel and the self-adhesive magnetic sheet 12 the field of attraction has maximum effect only when the elements are in direct contact. The attraction is lost when the respective element 12 is even separated by only a few millimeters from the panel P. Considering this rule and the fact that the respective element 12 must support the weight of the element 10, it is important that the element 12 is at the same level in - a plane parallel to panel P. As mentioned above, said element 12 is also influenced by the weight of element 10. Element 12 is characterized by thickness and isotropy. On a lighter ceramic plate, the self-adhesive magnetic sheet 12 may be isotropic, and on heavier ceramic plates 10, the respective element 12 will be anisotropic. The thickness of the respective element 12 varies from 0.5 mm to 2 mm.

In a preferred embodiment, the element called 12 is isotropic and has a thickness of 1 0.75 ... 1 mm. The dimensioning of the respective element 12, as well as the choice of an isotropic or anisotropic material will be made depending on the surface of the element 10 and its weight 3. It is possible to reduce the thickness of the element 12 and obviously its magnetic attraction by increasing the frictional force, and this can be achieved by increasing the surface 5. There is a direct relationship between the mass and the dimensions of the ceramic plates 10 and the isotropy of the thickness and the magnetic force of the self-adhesive magnetic sheet 12. Therefore, the only dimension and correct assembly of the respective element 12 can be obtained only if the ceramic plate is known 10. 9

After sitting on panel P for a long time, the ceramic plate

10, taken from the panel by using said element 12, is difficult to detach because 11 the magnetic field increases proportionally with the contact time. Therefore, disassembly tool 13 is intended to safely remove ceramic tiles 10. Item 13 13 is important because the described system is required to be safe when updating a collection. Ceramic tiles are heavy items, and removing them from the respective panel P 15, taking into account the difficult position of the body during this operation, and grabbing the plates insufficiently by hand, can lead to accidents. The 17 disassembly tool 13 is a metal tool, designed and built for this purpose; the tool is characterized by the fact that the top is u-shaped and can support a ceramic plate 19. The wings of the "u" profile are thin, and one of the wings can easily reach below the element 10, and detach it with a short upward movement, as illustrated 21 in FIG. 8I. Also, this tool is provided with a handle that facilitates handling. From the point of view of the procedure of removing the plates, the tool is used with 23 one hand, while with the other hand the ceramic plate 10 is held on the opposite corner.

It is not enough just to magnetically attach the plates to a panel. The spacing and alignment of the plates must be observed in order to obtain a good looking display panel. This is why a practical, cost-effective and 27 intuitive template is needed.

The modular template 14 is characterized by the fact that it is magnetic and made 29 from a thin, wood-based panel with magnetic foil attached to it. The thickness of the modular template 14 varies between 2 mm and 20 mm. In a preferred embodiment, the modular template 14 does not exceed the thickness of 6 mm to 12 mm. The modular template 14 is also cut in accordance with the desired configuration for the panel, and can be produced in any form necessary to perform its primary function - the correct placement and spacing of the respective ceramic plates 10 on the surface of the panel P. The manufacture of the element 14 is simple - the piece of wood-based panel and the magnetic foil are glued together, and then cut with the laser or CNC (numerically controlled machine) 37 to the desired shape. Each part of the modular template 14 is inscribed with a position code that will also appear in the instruction book included in the upgrade kit. When upgrading 39, it is sufficient to position each part of said element 14 on panel P as instructed in the upgrade kit. 41

Fig. 9 describes the production process for panel P. The raw material is the sheet of metal that is delivered pre-painted, as shown above, and at the desired width 43. The thin sheet metal 4 is suspended on a feed device which rolls the sheet metal. The line speed is an interpolation between the roll speed of the sheet metal and the 45 adhesive hardening speed - element 3. In a preferred situation, the line speed is 3 to 9m / min. The higher the adhesive curing speed and the rolling speed, 47

RO 131258 Β1 the higher the production. The adhesive is stretched with an oscillating device, the dosing element 24 and the amount of adhesive poured. In a preferred situation, the adhesive consumption should not exceed more than 100 ... 150 g / m ² . The base panels 2 are loaded manually or automatically. The automated loading solution refers to a lift that loads the base panels 2, and to a push bar that advances the element on the roller table, element 20. As we have shown above, the panels are centered and aligned on the left. and on the right with the guide rollers, the element 22, and are further pushed on the line by the feed rollers, the element 21. Also, the metal sheet is centered with a set of guide rollers, the element 23. at this point and a first pressing. Throughout the operation there is a synchronization between the feed rollers of the base panel 2, the element 21, the feed device of the metal sheet and the device of tension of the glue, the element 24. finally the pressing is executed with the set of pressing rolls 25. Pressing it is cold, with no heating required. Also, the panels are cut to length, since cutting to width is not necessary because the sheet metal is cut to size and pre-painted, and the base plate in rough condition also comes with the width cut to size. The element 26 that performs the length cut is synchronized with the feed device of the panel so as to cut only the oversize of the base panel 2. So, if the final length of said panel P will be for example 2000 mm, then the respective panel base 2 will have a length of 2010 mm, of which the element 26 will cut 5 mm at the entrance and 5 mm at the exit, dimensioning the panel after the metal sheet applied at 2000 mm. After sizing, it is possible to add a device for attaching the protective film to the surface of panel P, because, normally, the panel no longer supports other interventions, and can be delivered as is. The protective foil can be applied even if panel P requires other operations, such as edge coating. As mentioned earlier in the detailed description chapter of the drawings, applying a thin sheet of metal on the other side is possible by starting the other side of the line (bottom).
