Definitions
- the present invention relates to a method for providing laminate panels provided with individualized decorations, a laminate panel produced using this method, and a device for carrying out this method.
- Laminate panels have become indispensable for a wide range of applications, especially as a replacement for real wood panels.
- a particularly large area of application is the cladding of walls, ceilings and floors, where the respective cladding is put together from corresponding wall, ceiling and floor panels.
- different requirements are placed on the surface properties of such laminate panels in different areas of application.
- a floor panel is naturally exposed to much greater loads than, for example, wall or ceiling cladding.
- a carrier board for example made of a wood material such as chipboard, MDF, FIDF or OSB, is provided and this is coated with several layers of possibly different materials.
- a decorative layer is applied to an optionally pretreated surface of a wood-based panel. This can take place, for example, in the form of a printed impregnated paper. The decor can also be printed directly on the top of the wood-based panel. This can be done by means of pressure rollers or a digital printer.
- a primer layer can optionally also be applied to the surface of the wood-based panel.
- This decoration in particular if the panel is to be used as a floor panel, must be covered by at least one abrasion-resistant protective layer, for example made of paint or resin.
- the layer structure is then pressed in a press under the influence of pressure and temperature.
- the still large-format, now coated, wood-based panel is divided into individual panels, which are provided with locking means in the form of a tongue and a groove on the side surfaces, so that the panels can be connected easily.
- a major topic in many product areas of wood-based panels today is individualization. The customer often wants a product that is tailored to his or her individual wishes and / or needs. The customer is also prepared to accept a higher price for this additional service.
- New technologies such as digital printing or 3D printing are developing possibilities for manufacturers to realize both small quantities (keyword: number of pieces 1) and new production possibilities outside of the classic production lines. Many products are affected by these tendencies, including floor coverings. These were usually produced in large quantities per decor in the manufacturers' factories. The decors were mostly developed by suppliers (designers, printers, etc.) and then distributed to the industry. A collection was then created by the flooring manufacturers from a certain number of decors and made available to the flooring dealers and thus also to the end customers for selection.
- the present invention is therefore based on the technical problem of providing a device that enables the end customer to purchase a floor he designed himself at the point of sale (POS), such as a building supplies store, which he can take away immediately. It is possible to work either with your own or with existing decors (in digital form). For the employees at the point of sale, the operation and maintenance of the system used to manufacture the floor should be as simple and safe as possible. There should be no emissions or unpleasant odors. In addition, the rectification of problems, maintenance and replacement of the system should be as easy as possible.
- the laminate panel blank comprising a carrier plate pressed with a coating as a pressure primer and at least one counter-tension and connecting elements inserted into the panel edges,
- thermoplastic film as a wear layer onto the printed decoration, the printing of the selected decoration and the pressing of the at least one thermoplastic film onto the printed decoration taking place at the point of sale (POS).
- POS point of sale
- Party A is to be understood as meaning, in particular, a laminate manufacturer, including a supplier, dealer or the like, who provides a party B with laminate panel blanks for individualization in the manner of an intermediate product.
- Party B is to be understood as meaning, in particular, an end user, including interior designers or architects who use laminate panels as a finished end product for cladding floors, walls and / or ceilings or who offer them for use.
- a method (and a device for carrying out this method) is provided, a non-individualized laminate panel blank being initially provided by the manufacturer.
- the manufacturer presses a large-format carrier plate with a primer layer, possibly a primer and a counter-layer, the primer layer having a uniform, preferably light, color.
- the primer layer can be provided with structures.
- the pressed, large-format plate is divided into individual panels and provided with known locking elements on the side edges.
- the manufacturer thus provides (small-format) Laminate panel blanks with a high degree of processing ready (ie with pressure primer and connecting elements), which can then be individually designed by the end user.
- the manufacturer delivers the small-format laminate panel blank to a point of sale (e.g. hardware store).
- a decoration individually designed by the end user is digitally printed and this printed decoration is provided with a wear layer based on a film.
- the application of liquid paint or resin layers as a wear layer is therefore dispensed with, so that the finishing process can be carried out more easily and safely. In particular, emissions or unpleasant odors for employees at the point of sale are avoided.
- the end user also has the option of integrating their own decors or inlays into the floor. Complex multi-layer structures on the laminate are not provided with the present method at the point of sale, since this would lead to an increase in the price of the product, which is precisely what is not desired.
- there are no load distribution layers, stabilization layers or damping layers e.g. made of cork, felt, fleece, wood-plastic composite (WPC), fiberglass-reinforced plastic, hot melts or similar materials.
- the system used for the present process at the point of sale comprises a magazine in which laminate panel blanks (coated, primed and provided with tongue and groove) are located.
- the laminate panel blanks are printed with a digital printer either with decors that the system supplier makes available to the end user or with decors that the end user transfers to the system via a digital file (e.g. stored on a USB stick).
- a digital file e.g. stored on a USB stick.
- the result of the adjustments can be assessed not only on a screen but also on a printout.
- a film, which is optionally provided with a layer of lacquer on the top, is then applied to the printed decoration with the aid of a heated roller.
- the laminate floor blanks are delivered to the POS solves the problem of supplying end customers with small quantities that has arisen as a result of the individualization. In this way, minimal quantities (e.g. lot size 1) can be individually designed for the end user. This would not be possible with the laminate manufacturer himself.
- the possibility of Individualization of a product by the end customer himself is the maximum possible participation of the end user in the production of the product.
- the laminate panel blank with the pressure primer, backing and locking elements is provided by the laminate manufacturer.
- the laminate panel blank comprises a wood-based panel as the core or carrier board, which can be a medium-density fiber (MDF), high-density fiber (HDF) or chipboard or coarse chipboard (OSB) or plywood board and / or a wood-plastic board.
- MDF medium-density fiber
- HDF high-density fiber
- OSB coarse chipboard
- a non-sanded wood fiber board in particular MDF or HDF, is used as a carrier board for the laminate panel blank, which is also provided with a pressed skin (rotting layer) on the upper side, and has been treated with an aqueous melamine resin on the upper side in order to protect the pressed skin to fill.
- the dimensions or dimensions of the laminate panel blank correspond to the formats that are typically available in retail (e.g. hardware stores).
- the laminate panel blank can have dimensions of 1395 ⁇ 195 mm with a thickness between 4 to 15 mm, preferably 6 to 12 mm (small format).
- other formats would also be possible.
- the at least one laminate panel blank has a coating as a printing primer.
- This primer is applied to large-format carrier plates by the manufacturer.
- the primer is in particular colored. In particular, several colors are possible here, such as white, beige, yellow or brown.
- the at least one printing primer consists of a liquid coating made of a resin, preferably a formaldehyde resin, such as melamine-formaldehyde resin, urea-formaldehyde resin or melamine-urea-formaldehyde resin.
- a pigmented layer is applied to this primer, for example with a binder based on casein or soy protein.
- White pigments such as titanium dioxide (T1O2) can be used as color pigments. Further color pigments can be calcium carbonate, barium sulfate or barium carbonate.
- the liquid primers can be applied to the surface of the carrier plate using a roller.
- the primers consist of at least one, preferably of at least two or more successively applied layers or orders, the amount applied between the layers or orders being the same or different, i.e. the amount applied for each individual layer can vary.
- the at least one printing primer consists of a colored paper impregnated with a resin.
- colored papers are used as the printing base, the color of which corresponds to the lightest shade of the decor to be printed. If, as in the present case, the decor to be applied is not yet known, a white or at least very light primer is therefore advantageous. Any other color is also conceivable as a primer.
- the large-format panel provided with the at least one pressure primer is pressed with a counter-tension. At the panel manufacturer, this is usually done in a short-cycle press. A structure can be introduced into the printing primer during the pressing process.
- At least one primer layer can be applied to the at least one printing primer (at the panel manufacturer).
- Isocyanate-based compounds can be used as primers, non-aromatic, aliphatic isocyanates, such as hexamethylene diisocyanate, isophorone diisocyanate, or prepolymers which contain these isocyanates being particularly preferred.
- Primers based on silane can also be used, such as products from Inomat GmbH. These contain acidolysis products from silanes, for example from bis (3-trimethoxysilylpropyl) amine and p-toluenesulfonic acid.
- the amount of the applied liquid primer is in the present case between 1 and 30 g / m 2 , preferably between 5 and 20 g / m 2 , particularly preferably between 10 and 15 g / m 2 .
- a separating film can be provided to protect the printed decoration and the primer against soiling and against sticking of the laminate floor blanks during transport and storage to the POS.
- films with a silicone coating can be used as separating films.
- the described steps of priming and, if necessary, application of a primer layer and pressing are carried out in large format at the manufacturer.
- the primed large format is then divided or formatted by the manufacturer into the desired number of laminate panel blanks.
- the now formatted laminate panel blanks are provided by the manufacturer with a lockable tongue and groove connection on at least two mutually opposite edges of the panel. This enables quick and easy floating installation of the panels.
- tongue and groove connections are known, inter alia, from EP 1 084 317 B1.
- the laminate panel blank provided by the manufacturer accordingly comprises a wood-based panel as a carrier plate with at least one pressure primer, if necessary a primer layer provided on the pressure primer, a counter-tension opposite the pressure primer and lockable tongue-and-groove connections provided on at least two opposing edges of the panel.
- the laminate panel blanks are stored in a central warehouse at the laminate manufacturer. In particular, they can be cleaned and packaged beforehand in such a way that they can be printed or processed directly in the processing plant without the panels having to be cleaned again there. It now only has to be kept for a single type of panel, so that space-intensive storage of panels with different decors, different surface structures or different surfaces is no longer necessary.
- the laminate panel blanks are then transported to a processing company for customization.
- a processing company for customization.
- This can be, for example, a franchise company associated with the laminate manufacturer, a hardware store, an interior designer, dealer or flooring company.
- the laminate panel blanks are unpacked from the transport-safe packaging.
- a decorative layer with a decor according to the customer's immediate requirements is applied to the primer or the primer and covered by at least one wearing layer.
- the at least one decoration is applied to the laminate panel blank by means of a digital printing process.
- digital printing the print image is transferred directly from a computer to a printing machine, such as a laser printer or inkjet printer. There is no need to use a static printing form.
- the decor is printed according to the inkjet principle in a single pass, in which the entire width of the upper side to be printed is spanned, with the panels being moved under the printer.
- the panel it is also possible for the panel to be printed to be stopped under the printer and the printer to run over the surface at least once during printing.
- the digital printing process enables a decor selection that corresponds to the customer's wishes, since the decor can be provided in the form of individualized computer data / software.
- the laminate panel blanks are printed with a digital printer either with decors provided by the system supplier or with decors that the end user transfers to the system via a file.
- the result of the adjustments can be assessed not only on a screen but also on a printout.
- the laminate panel blank runs through a digital printer. This makes it possible, in particular, to print different decors quickly and easily one after the other on different panels without having to convert the printing unit to a new decor in each case. Because only individual panels have to be printed and not, as is common in the prior art, entire large-format wood-based panels, the printing unit can be made small and compact and thus space-saving and inexpensive.
- the printing inks are combined in separate rows of print heads in the digital printer, it being possible for one or two rows of print heads to be provided for each color.
- the colors of the Digital printing inks are, for example, black, blue, red, reddish yellow, greenish yellow, CMYK can also be used as an option.

- the film is in particular laminated or calendered.
- the calendering is preferably carried out with a structure roll exposed to temperature.
- the term “calendering” is to be understood as meaning the application of a thermoplastic film to a carrier plate using heated rollers. This leads to a melting of the surface of the thermoplastic film, which after Curing is connected to the surface of the carrier plate or is welded to the carrier plate and thereby adheres to the carrier plate. Accordingly, no gluing is necessary.
- the at least one thermoplastic film is provided or coated with at least one lacquer layer.
- the thermoplastic film is provided together with the lacquer layer; i.e. the lacquer layer is already cured on the film, so that it is not necessary to apply and harden the lacquer layer at the POS.
