Definitions

  • the invention relates to a floor panel with at least one bevel, a floor panel arrangement, and a method for producing such a floor panel.
  • Floor panels such as laminate, are a popular flooring option that consists of individual panels, each made from multiple layers.
  • fiberboard is used, with additional layers on the top and bottom surfaces.
  • These layers can be made from paper, for example, which is often soaked and impregnated with special resins.
  • These layers typically include an overlay on the top for added durability, a decorative paper for visual impact, and a top layer to withstand wear and tear.
  • a counterbalance and, if necessary, an underlay for impact sound insulation are usually added to the bottom.
  • EP 3 578 383 B1 discloses a method for finishing a prepared board.
  • a decorative paper is applied to the top side, followed by an overlay paper as an abrasion-resistant layer.
  • a countercoat is applied to the underside. When the layers are pressed together, a relief is pressed in, which can correspond to a bevel.
  • a bevel is a chamfer that is usually arranged at the edge of a floor panel, so that when two floor panels are placed together, a complete joint is created by two bevels arranged at the edge of the floor panels.
  • EP2774770B1 discloses methods for printing a wood-based panel with a decorative layer by means of a digital printing process using various layers of lacquer and/or resin as well as a protective layer.
  • One aspect of the invention relates to a floor panel with at least part of a bevel, wherein the floor panel comprises a plate-shaped core with a visible printed layer, an overlay on the visible printed layer such that the visible printed layer is protected by the overlay and at least one bevel which is pressed into the plate-shaped core by the overlay, wherein the visible printed layer on a surface of the at least one bevel has an effect for enhancing an optical depth effect of the bevel.
  • One embodiment relates to a floor panel, wherein the offset of the joint is between 0.2 mm and 0.6 mm.
  • One embodiment relates to a floor panel, wherein the effect comprises a color gradient.
  • the color gradient comprises different colors, shades and/or brightnesses, wherein in particular the color, shade and/or brightness in is darkest at a center of the width and/or increases along the width with distance from the center.
  • the color gradient creates the visual impression that the darker areas are deeper than the lighter areas.
  • the color gradient involves the color being darker at deeper points of the bevel than at less deep points of the bevel or at non-pressed areas.
  • the color gradient runs from a darker color at the most deeply pressed point of the bevel to a lighter color at a non-pressed area.
  • the optical effect includes fully opaque or transparent, i.e. not fully opaque, colored areas that stand out from the color of the decor, in particular a basic color of the decor. These can be used as a single colored area or as a combination of several such colored areas. When using several colored areas, different colors can be used that differ to varying degrees from the basic color of the decor. Alternatively or additionally, these multiple colored areas can also differ in their degree of transparency. The greater the degree of transparency of the colored area, the more clearly the underlying color of the decor can be seen through the colored area. A transparency level of 1 means complete transparency, a transparency level of 0 means no transparency, so that the underlying colors of the decor do not shine through this colored area.
  • the advantage is that the floor panel can be given almost any look desired by the customer thanks to the decor.
  • the decoration is arranged in an area on top of the printed layer, with the area of the decoration being distinct from the wider area in which the effect is arranged to enhance the optical depth of the bevel.
  • Possible examples of decorations can include imitations of wood, stone, concrete, cork, or other materials, as well as combinations and variations thereof, as well as fantasy patterns.
  • a walnut decor in a dark brown tone can be used to create a particularly deep bevel as a combination of printed and pressed bevel.
  • the pressed structure for the decor can contain areas where the bevel(s) are embossed.
  • the bevel(s) can be visible on the edges of the finished panel.
  • a gradient from dark gray to black is used for the bevel area when printing the bevel.
  • an anthracite/black color gradient can be created at the positions that correspond to the bevel edge after further processing.
  • the gradient can, for example, be structured so that black is printed at the deepest point of the pressed bevel and fades to dark gray down to the surface level.
  • markings can optionally be inserted into the print data at the positions that are omitted during the further processing step of sawing and profiling. These can be used, on the one hand, to align the impregnated paper sheets in the cutting and sawing process using cameras and a control unit, as well as the pressed panels during sawing. This enables the precise positioning of the printed bevel(s) along the edges of the finished panel or at the positions of the pressed bevel.
  • the printed color gradient at the positions of the pressed bevel gives it a significantly deeper visual appearance. The contrast with the medium gray tone is high and stands out clearly from the rest of the installed flooring surface. Without the visual enhancement provided by the pressure in the area of the pressed joint, the visual effect of a deep bevel would not be possible.
  • a color gradient could be a concrete decor in a medium gray tone with a particularly deep bevel, which is created using a combination of printed and pressed bevel.
  • a gradient from dark anthracite to black is used for the printing of the bevel.
  • an anthracite/black color gradient is created at the positions that correspond to the joint edge after further processing.
  • the gradient is structured so that black is printed at the most deeply pressed point of the bevel and then fades to brown up to the surface level.
  • markings can be inserted into the print data at the positions that are omitted during the further processing step of sawing and profiling.
  • the bevels can also be located additionally or solely in the middle of the floor panel and not just at panel transitions. This could be the case, for example, with a panel that imitates a herringbone pattern.
  • the individual slat transitions can be printed for optical enhancement and additionally pressed as a bevel. Any color variation within the printable color space is possible in order to achieve the best possible depth impression or the desired effect. This can include, for example, solid colors, straight gradients, or even structured/speckled variants. Grids or line combinations are also conceivable to achieve specific effects. There are hardly any restrictions in this regard, especially in digital printing.
  • the printed color gradient at the positions of the pressed bevel gives it a much deeper visual appearance.
  • the printed layer also includes markings or control characters, so that the effect can be positioned precisely at the pressed bevel using an optical alignment system.
  • markings or control characters so that the effect can be positioned precisely at the pressed bevel using an optical alignment system.
  • This has the advantage that the positioning of the equipment used for pressing is simple and precise using the control characters, so that the pressed joint precisely matches the optical effect for the bevel. Contrasting colors are preferably used for the control characters.
  • the control characters can include, for example, lines, dots, or combinations thereof.
  • the control characters are preferably arranged in areas that are not visible on the finished panel, e.g. because they are cut away in a processing step.
  • the area in which the bevel is printed can correspond to the area in which the bevel is pressed.
  • the area in which the bevel is printed can protrude beyond the area in which the bevel is pressed.
  • This protrusion can have various dimensions.
  • the area of the printed bevel protrudes beyond the area of the pressed joint by the value of the tolerances of the machines used.
  • the tolerances can be 1 mm, for example. This ensures that even small deviations in the positioning of the pressed bevel compared to the printed bevel, e.g. due to inaccurate adjustment, do not result in defects. This serves quality assurance and, at the same time, low consumption of printing ink.
  • the panels can be placed against one another along the length of the panel in addition to being joined at the bevels.
  • a bevel is not necessarily present along the length of the panels.
  • a continuous floor covering can be formed by arranging a large number of panels. This floor covering has joints formed by two adjacent bevels at a large number of boundaries between the individual panels, and has no joints at a further large number of boundaries between the individual panels.
  • the arrangement of at least two floor panels results in a complete joint being formed at the interface between each two panels when they are placed with their bevels against each other.
  • the depth of the complete joint affects significantly deeper due to the effect of the bevel, which is arranged at the edges of the panels placed against each other, to enhance the optical depth.
  • the bevels can be printed onto the print layer and pressed into the floor panel so that the bevel is formed so that half of the joint is located on one panel and the other half on the adjacent panel.
  • Other divisions are also conceivable, e.g., 1/3 and 2/3, or the joint is completely or almost completely (e.g., > 90%) located on one of the two panels, while the adjacent panel has no or almost no joint (e.g., ⁇ 10%).
  • An arrangement of a plurality of floor panels can, for example, be designed such that bevels are located along the width direction of the individual panels, each of which is formed by placing the bevels together at the edges of the individual panels.
  • bevels are located along the width direction of the individual panels, each of which is formed by placing the bevels together at the edges of the individual panels.
  • two opposite edges of a panel each have a bevel, so that when placed together, a complete joint is created at the boundary between two panels.
  • the bevel of one panel at one edge can have the right half of a V if the V is split in the middle with a vertical cut, for example, the opposite edge of the panel has a bevel corresponding to the left half of a V, wherein the deepest point of the bevel's indentation is preferably located at the boundary between the two panels.
  • the darkest color tone of the effect is preferably located at the point on the panel that is pressed in the most deeply, in order to enhance the optical depth effect of a bevel.
  • a further aspect of the invention relates to a method for producing a floor panel with at least one bevel, wherein the method comprises providing a plate-shaped core with a visible printed layer and an overlay on the visible printed layer, such that the visible printed layer is protected by the overlay. Furthermore, the method comprises pressing at least one bevel, wherein the printed layer on a surface of the at least one bevel has an effect for enhancing an optical depth effect of the bevel.
  • the overlay is applied to the print layer so that the overlay at least partially covers the print layer.
  • the overlay can be a paper layer impregnated with resin and provided with abrasion-resistant particles.
  • the overlay can be applied by pulling the overlay from a pallet onto a stack of countersheet, decorative paper and overlay in front of the short-cycle press, placing it on top and then pressing the stack into a laminate.
  • the overlay can be a liquid overlay.
  • the liquid overlay can comprise one or more liquid resin layers.
  • abrasion-resistant particles are sprinkled onto at least one resin layer. If there are multiple resin layers, intermediate drying can take place. During intermediate drying, the resin layer is only dried and thus retains a large part of its reactivity, which is utilized under the influence of pressure and temperature in the short-cycle press.
  • the method may further comprise providing a carrier material.
  • the carrier material may be a paper web.
  • the carrier material may have a decoration.
  • the carrier material may be arranged between the plate-shaped core and the printing layer.
  • Possible printing methods include digital or analog printing.
  • a digital printing system can print the decorations and the optical effect to enhance the depth of the bevel in the same step.
  • one or more printing rollers can be used, e.g., using the indirect gravure printing method on a plate.
  • An exemplary system for producing the floor panels according to the invention includes, for example, an automated panel loading system, priming and drying units, an inline primer, an analogue printing system with printing rollers or a digital printing system, a cooling device, and a stacking system.
  • the creation and preparation of the print data can be carried out, for example, in prepress using an image processing program.
  • the layers can be bonded together, for example, by gluing and/or pressing. If pressing is used, the pressing of the joint part into the panel can be performed in a separate step from the pressing of the layers, or in the same step.
  • Another example relates to a method for producing a floor panel, wherein the step of applying the printing layer, when a carrier material in the form of a paper web is used, comprises applying the printing layer beyond the plate-shaped core, wherein the paper web is pressed to the plate-shaped core.
  • the print layer is applied in an area that extends beyond the area in which the print layer is visible in the finished panel.
  • the protruding part of the print layer is cut or sawn away in a later process step.
  • the advantage is that even minor deviations from the planned dimensions and positioning of the print layer or the other layers of the panel do not result in defects. This allows for some tolerances.
  • the print layer can be printed 1 mm beyond the area of the planned panel dimensions, and if the area actually protrudes in the finished panel, this excess area is then cut away.
  • the described components of the embodiment each represent individual, independently considered features of the invention, which also further develop the invention independently of one another and are thus also to be considered as components of the invention, either individually or in a combination other than that shown. Furthermore, the described embodiment can also be supplemented by further features of the invention already described.
