Definitions

  • the present invention relates to a method for providing laminate panels provided with individualized decorations.
  • Laminate panels have become indispensable in a wide range of applications, especially as a replacement for real wood panels.
  • a particularly large field of application is the cladding of walls, ceilings and floors, where the respective cladding is assembled from corresponding wall, ceiling and floor panels.
  • different requirements are placed on the surface quality of such laminate panels in different areas of application.
  • a floor panel is naturally exposed to significantly greater loads than, for example, a wall or ceiling covering.
  • a carrier board for example made of a wood-based material such as chipboard, MDF, HDF or OSB, is provided and this is coated with several layers of optionally different materials.
  • a decorative layer is applied to an optionally pretreated surface of a wood-based panel. This can be done, for example, in the form of a printed impregnated paper. The decor can also be printed directly onto the top of the wood-based panel. This can be done using printing rollers or a digital printer.
  • a primer layer can optionally also be applied to the surface of the wood-based panel.
  • this decoration must be covered by at least one wear-resistant protective layer, eg made of lacquer or resin.
  • the layer structure is finally pressed in a press under the influence of pressure and temperature.
  • the still large-format, now coated wood-based material board is then 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 their individual wants and/or needs.
  • the customer is also willing to accept a higher price for this additional service.
  • the present invention is therefore based on the technical problem of providing a method that enables the end customer to purchase a self-designed floor at the point of sale (POS), such as a hardware store, which he can take with him immediately. It is possible to work either with your own decors or with existing ones (in digital form).
  • POS 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 odor nuisance.
  • the elimination of problems, the maintenance and the reloading of the system should be as simple as possible.
  • Party A is to be understood in particular as a laminate manufacturer, including suppliers, dealers or the like, who makes laminate panel blanks available to Party B for individualization in the manner of an intermediate product.
  • Party B is to be understood in particular as an end user, including interior decorators or architects, who use or offer for use laminate panels as a finished end product for cladding floors, walls and/or ceilings.
  • a method in which a non-individualized laminate panel blank is first provided by the manufacturer.
  • the manufacturer presses a large-format carrier plate with a primer layer, optionally a primer and a balancing layer, with the primer layer having a uniform, preferably light color.
  • the primer layer can be provided with structures.
  • the pressed, large-format board is divided into individual panels and provided with well-known locking elements on the side edges. The manufacturer thus Laminate panel blanks with a high degree of processing ready, which can then be individually designed by the end user.
  • the manufacturer delivers the laminate panel blank to a point of sale (e.g. hardware store).
  • a decor individually designed by the end user is digitally printed and this printed decor is provided with a wearing 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 simply and safely.
  • the end user also has the option of integrating their own decors or inlays into the floor.
  • the system used for the present method 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. saved on a USB stick). It is also possible to integrate inlays, names, etc. into a decor specified by the system supplier. Further processing of the decor files is also possible using simple software (rotating, mirroring, enlarging, reducing, etc.). In addition, the result of the adjustments can be viewed not only on a screen but also on a printout. A foil with a layer of lacquer on the upper side is then applied to the printed decoration with the aid of a heated roller.
  • the laminate panel blank is provided by the laminate manufacturer with the pressure primer, backing and locking elements.
  • the laminate panel blank comprises a wood-based panel as the core or carrier panel, which can be a medium-density fiber (MDF), high-density fiber (HDF) or chipboard or coarse particle board (OSB) or plywood panel and/or a wood-plastic panel.
  • MDF medium-density fiber
  • HDF high-density fiber
  • OSB coarse particle board
  • an unpolished wood fiber board in particular MDF or HDF, is used as the carrier board for the laminate panel blank, which is 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 fill the pressed skin .
  • the dimensions or measurements of the laminate panel blank correspond to the formats that are typically available in stores (e.g. hardware stores).
  • the laminate panel blank can have dimensions of 1395 ⁇ 195 mm with a thickness of between 4 and 15 mm, preferably 6 and 12 mm.
  • 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 boards 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 print primer consists of a liquid coating 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 base made from casein or soy protein.

  • the at least one printing ground consists of a colored paper impregnated with a resin.
  • colored papers are used as a print base, the color of which corresponds to the lightest shade in 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 advantageous. However, any other color is also conceivable as a primer.
  • the large-format panel provided with the at least one printing primer is pressed with a backing. This is usually done by the panel manufacturer 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 containing these isocyanates being particularly preferred.
  • Silane-based primers can also be used, such as products from Inomat GmbH. These contain acidolysis products from silanes, e.g. from bis(3-trimethoxysilyl-propyl)amine and p-toluenesulfonic acid.
  • the amount of liquid primer applied is 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 decor and the primer from dirt and to prevent the laminate flooring from sticking together during transport and storage to the POS.
  • Films with a silicone coating can be used as release films.
  • the steps described for priming and, if necessary, applying a primer layer and pressing are carried out in large format by 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 opposite edges of the panel. This enables the panels to be laid in a floating manner quickly and easily.
  • tongue and groove connections are, inter alia, from EP 1 084 317 B1 famous.
  • the laminate panel blank provided by the manufacturer therefore comprises a wood-based panel as a carrier board with at least one printing primer, if necessary a primer layer provided on the printing primer, a balancing sheet opposite the printing primer and lockable tongue and groove connections provided on at least two opposite edges of the panel.
  • the laminate panel blanks are stored by the laminate manufacturer in a central warehouse. In particular, they can be cleaned and packaged beforehand in such a way that they can be printed or processed directly in the further 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-consuming 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 individualization.
  • a processing company for individualization.

  • the at least one decor is applied to the laminate panel blank using digital printing processes.
  • Digital printing is the transfer of the printed image directly from a computer to a printing machine, such as a laser printer or inkjet printer. This eliminates the use of 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, which then runs over the surface at least once during printing.
  • the digital printing process enables decor to be selected according to customer requirements, since the decor can be provided in the form of individualized computer data/software.

In addition, the result of the adjustments can be viewed 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. Due to the fact that only individual panels have to be printed and not, as is usual in the prior art, entire large-format wood-based material panels, the printing unit can be designed to be small and compact and therefore space-saving and cost-effective.
