Definitions

  • This invention concerns on the one hand a method for the forming of a baseboard or finishing profile for flooring, comprising a wood-based carrier material, provided with a decorative top layer having one or more resin-impregnated layers.
  • this invention concerns a baseboard or finishing profile for flooring.
  • This invention concerns in particular a baseboard or finishing profile manufactured from a DPL, a DLP, a CPL or an HPL laminate.
  • This laminate is often used as flooring and can be of various kinds. Examples of such laminates are, among others, DPL (direct pressure laminate), HPL (high pressure laminate), CPL (continuous pressure laminate), LVT (luxury vinyl tiles), cushion vinyl (roll vinyl), WPC (wood plastic composite), DLP (direct laminate printing) or a combination of the abovementioned laminates.
  • a DPL panel is made up of a bottom layer of plastic, usually melamine, a carrier material, generally high-density fibreboard (HDF), on which a layer of printed paper is provided (usually printed with an imitation wood structure), with a plastic top layer, usually melamine reinforced with corundum or aluminium oxide.
  • a carrier material generally high-density fibreboard (HDF)
  • HDF high-density fibreboard
  • a layer of printed paper usually printed with an imitation wood structure
  • a plastic top layer usually melamine reinforced with corundum or aluminium oxide.
  • a DLP panel has more or less the same construction as a DPL panel, but it lacks the printed paper layer.
  • the HDF carrier sheet is directly imprinted and then processed with a top layer.
  • the carrier material can also be a WPC (wood plastic composite) sheet or some other plastic sheet.
  • planks which is laid in the form of planks on a base layer. These planks are usually interconnected with each other by means of a snap connection. Such planks are composed of a core which is made from MDF, HDF, PVC, PP or WPC (wood plastic composite). The top side of these planks is provided with a decorative top layer. This layer can contain one or more decorative layers and be covered by a scratchproof top layer, and depending on the application the implementation, structure, and scratch resistance can be different.
  • the decorative top layer can be formed of a laminate in the form of DPL (direct pressed laminate), CPL (continuous pressure laminate) or HPL (high pressure laminate), DLP (a digitally printed layer).
  • Decorative layers of PVC, PP low density or scratchproof paper are possible and belong to the prior art.
  • baseboards or profiles are available for the finishing of these floorings. Often, these baseboards or profiles are manufactured by providing a carrier profile with a film layer by means of the familiar process of sheathing.
  • the carrier material of sheathed profiles often consists of MDF, HDF or PVC.
  • the decorative film layers are often PVC film or paper film on which a print is applied which matches the respective flooring. For profiles such as transition profiles or adapting profiles a CPL film is often used, due to its scratch resistance.
  • a first problem is that such profiles or baseboards never fit the respective flooring perfectly.
  • the print or structure is almost never identical to the flooring.
  • this structure is not unimportant; many structures are "embossed in register", which means that the structure runs synchronously with the decor.
  • Such techniques or finishing grades are thus far not possible on films so that the finishing of the baseboard will always be of lesser quality than that of the floor.
  • a second problem with sheathed profiles is their durability. Under the influence of sunlight or UV light, discolouration or ageing will occur. As long as the top layer of the baseboards is not identical to the top layer of the floor panels, these will never age in the same way and in the end a serious colour difference can result between the baseboards and the flooring, which gets a less attractive finish.
  • a third problem with traditional sheathed profiles is that one has to lay in a stock of film for each decor or floor panel to make the aforementioned finishing strips or baseboards. These films often have to be purchased in large numbers, so that this is a costly matter for the floor manufacturer. Thanks to digital printing, one can keep these volumes to a minimum, but then the print or structure will still never be identical to the respective floor panel. Also, digitally printed films often do not have the necessary scratch resistance, so that they cannot be used for finishing strips which are walked upon.
  • BE 1019285 is consequently not suited to making baseboards or finishing strips of sheet material whose decorative top layer is very thin (at most 0.35 mm), brittle and fragile, such as that made from DPL or HPL sheet material. Namely, it has been found experimentally that the top layer will break or tear upon making the slightest fold or exerting the least pressure.
  • the purpose of this invention is to create a method which allows the fabricating of a baseboard or finishing profile from a sheet material with a hard and brittle top layer, such as a DPL or HPL sheet material, and which is just as attractive or high in quality as the traditional baseboards or profiles.
  • a hard and brittle top layer such as a DPL or HPL sheet material
  • the decorative film or top layer runs uninterrupted across the entire visible side of the baseboard or the finishing profile.
  • the purpose of the invention is achieved by providing a method for the forming of a baseboard or finishing profile for flooring which comprises a wood-based carrier material, provided with a decorative top layer having one or more resin-impregnated layers, wherein the method involves the following steps:
  • the thickness of the remaining portion of carrier material is between 0.2 and 0.8 mm, more particularly between 0.2 and 0.6 mm.
  • a baseboard for a wall of a room or finishing profile for flooring comprising a body made up of at least one wood-based carrier material, and a decorative top layer having one or more resin-impregnated layers, wherein said body comprises a lengthwise part forming at least one portion of the front of the baseboard or the finishing profile, and a top part that forms at least one portion of the top of the baseboard or the finishing profile, wherein the transition between the lengthwise part and the top part has a curved course, wherein at the height of said transition a remaining portion of carrier material is provided with a thickness between 0.03 and 1.4 mm and this across a width of at least 2 mm, and wherein opposite said remaining portion a support layer is provided for the remaining portion of carrier material with decorative top layer having a different composition than the carrier material.
  • the method according to this invention involves at least the following steps:
  • the decorative top layers of DPL and DLP sheet materials are very thin or almost nil. If we want to bend these top layers in a mechanical manner, we need to leave a limited amount of HDF layer or carrier material in the fold part, or else this top layer will break or tear outright. On the other hand, we cannot leave behind too much carrier material: the thicker the carrier material, the harder it is to bend. This will make the radius formed at the top of the baseboard increasingly large and we will no longer be able to fold, for example, the top side of a baseboard by 90°. Since HDF or wood is not thermoplastic, we need to take into account the properties of HDF in order to make the folding possible. Yet we see that a thin layer of HDF when heated becomes more slack and less brittle.
  • the decorative top layer of DPL sheet material has a total thickness of +/-0.2 to 0.3 mm.
  • the decorative paper has a thickness of +/-0.05 mm. Such tolerances are not attainable for many machines. Any way, one must not cut through the decorative paper, or else a part of the decoration or print will disappear or exhibit small cracks. DLP floor panels do not have any printed paper, but rather the print is pressed directly onto the carrier material. In this way, it is not possible to remove all of the carrier material in order to employ a kind of post-forming for the forming of a baseboard. One must also take account of the fact that one has to cut away the carrier material across a well defined width B.
  • the top layer is provided with thermoplastic melamine resins. If we heat the top layer it becomes less brittle, so that the material in the fold part can be folded by a smaller radius.
  • the DLP floors have no printed paper layer, but rather the decoration is printed directly onto the carrier material. However they are provided with a scratchproof transparent top layer. This heating also has advantages for the folding of the formed fold part.
  • the heating of the top layer brings benefits for the folding of the material in the fold part.
  • this will begin to scorch at a certain temperature.
  • the baseboard will begin to scorch during the production, with all the risks this entails.
  • We must therefore pay attention when heating the top layer.
  • the DLP floors have no printed paper layer, but rather the decoration is printed directly onto the carrier material. However, they are provided with a scratchproof transparent top layer. This heating can also have advantages for the folding.
  • the fold part needs to be very thin, or else we cannot fold it over. Once the baseboard has been formed, this zone will then also be a very weak one.
  • a reinforcement support layer
  • a filler which is to be applied in liquid form, so that it is easy to automate. Upon cooldown, the filler will harden, so that the remaining carrier material will be supported together with the decorative top layer.
  • This adhesive or filler will thus be injected during production into the recesses and it will harden after the folding over of the fold part.
  • the fold part can in theory take on any given shape.
  • the fold part will always have stresses, since it is folded over during the forming of the baseboard or finishing profile. Because this fold part is now entirely glued together by the adhesive, these stresses should be neutralized, which greatly reduces the likelihood that the decorative top layer will still exhibit cracks.
  • Fig. 1 Layout of a floor panel containing a carrier material (1), a decorative layer (7), a scratchproof top layer (6) and a backing (35).
  • the carrier material can consist of HDF, MDF, LDF, chipboard, WPC (wood plastic composite), etc.
  • the decorative layer (7) is a printed film which can be made from decorative paper (7) with a scratchproof layer on top of this.
  • the scratchproof top layer (6) is a transparent layer which protects the floor panel against scratching and dirt. Sometimes the decorative layer (7) and the scratchproof top layer (6) can be the same layer.
  • the decorative layer (7) and the scratchproof top layer (6) form the decorative top layer (2).
  • the backing (35) often serves to prevent warping.
  • Such floor panels depending on their construction are known as DPL (direct pressed laminate), HPL (high pressure laminate), CPL (continuous pressure laminate), etc.
  • Fig. 2 The panel from Fig.1 in which well placed recesses have created a fold part with a remaining portion (11) of carrier material with a width (B).
  • the thickness d1 is the thickness of the remaining layer of carrier material (residual layer) (1). Thickness d2 of the decorative layer (7) and d3 of the scratchproof top layer (6). The total thickness D of the fold part is thus d1+d2+d3.
  • the thickness d1 of the remaining portion of carrier material is preferably between 0.03 mm and 1.4 mm and in particular between 0.1 mm and 0.8 mm.
  • this fold part (11) In order to still bend this fold part (11) to a radius of, e.g., 5 mm, we must take advantage of the physical properties of the decorative top layer (2) on the one hand and the residual layer of carrier material (1) on the other. It is also important to keep as broad as possible a width (B) of the fold part (11), preferably greater than 2 mm, more particularly greater than 3 mm. In this way, we no longer have a folding line, but instead obtain a fold part (11) with a width B > 2 mm and a thickness D less than or equal to 1.7 mm. By means of intense heating of both the residual layer of carrier material (1) and the decorative top layer (7) at the height of the fold part (11), we can bend this fold part (11) across a certain radius (R).

Across this width B is produced a fold part (11) which is composed of the decorative film (6), the scratchproof top layer (7) and a very thin layer of carrier material (1) with constant thickness. The total thickness of the fold part (11) is D.
  • the side edges of the recesses (16) can be rounded or angular. It can also be that the thickness of the remaining portion of carrier material is not constant over the entire width (B), depending on the desired shape to be achieved.
  • Fig. 25 The fold parts (11) are heated by means of a heat source (20).
  • This heat source can consist of lamps, air blowers, etc. In this way, the fold parts (11) become more supple and less brittle.
  • the decorative top layer in the fold part must have a temperature between 80° C and 250° C.
  • a support layer is formed by placing glue (36) in the recesses (cutouts) (16).
  • the fold parts (11) are also heated further (20).
  • This glue can be a hot-melt glue, a PUR glue or a polyolefin glue, depending on the desired properties of the baseboard.
  • the quantity of glue (36) which is injected into the recess (16) depends on the volume (V) resulting in the glue chamber (L) after the bending of the fold part (11).
  • Fig. 27 The fold parts (11) are bent to a certain radius (R). This produces a glue chamber (L) with a volume (V). Given that the fold part (11) is much more fragile, it is of great importance that the fold part (11) be completely supported by the adhesive (36) with which the glue chamber (L) is filled. It is important that the fold part (11) be continually heated during the folding, or else there is a danger that the fold part will cool down too much, so that it would break during the folding.
  • Figs. 28 a and 28 b We can further work the shaped profile until the desired shape is obtained. Still more profilings can also be provided on the back side in order to fasten the baseboards to the wall with a clip system.
