Definitions

  • the invention relates to a method for edging wood-based panels, in which the following steps are carried out: Providing a wood-based panel having a lower density in the middle layer than further out, wherein the wood-based panel has a parallel to the middle layer extending top and bottom and at least one of the top Having on the underside running narrow side, wherein the narrow side has a width and a length, producing a cover edge, wherein the cover edge is formed of a wood material, rolling the cover edge to a roll goods, rolling the roll goods and sticking the cover edge on the narrow side of the wood material board below Use of an adhesive.
  • a corresponding method is from the EP 2 052 822 A1 known.
  • lightweight panels are to be understood with a light middle layer and an upper and lower cover plate of a wood material, often plastic strips are glued as cover edges with the narrow side of the wood-based panel.
  • the Bekanten of wood-based panels increases the one hand, the stability in the narrow side, on the other hand, but also has the advantage that the porous middle layer is not apparent by the coating, such as a film or a laminate to the outside when coating particleboard.
  • the middle layer in the region of the narrow side telegraphed through the coating.
  • the situation is similar with lightweight panels, which often have a layer of a honeycomb structure, for example a cardboard honeycomb structure, as the middle layer, since here too the middle layer after coating the narrow side with a thin foil or the like would be outwardly apparent.
  • a cover edge is also used as additional support in the edge area.
  • plastic as the material for the cover edges is very well suited for certain applications. But it can also be preferred for artistic and / or cost reasons, to dispense with plastic strips. It is known in particleboard to use a plate type with a higher middle layer density. At high center layer density, the edge region is more stable and cabled, especially after a separate grinding step, no longer so easily through a thin coating. The production of such chipboard is relatively expensive. Incidentally, only to increase the edge quality, the overall plate receives a relatively high weight, which also complicates the handling of the plate.
  • a lightweight panel For lightweight panels, it is also known to use in the region of the side edge of a bolt of wood material between the cover layers, which supports the slight center layer and also stabilizes the edge region.
  • a lightweight panel is for example from the DE 10 2006 027 281 A1 known.
  • bars can be provided only as a rod product.
  • such a bolt also increases the weight of a wood-based panel designed as a lightweight board.
  • the wood-based panel is either a panel that can be made entirely of wood particles provided with a binder and compressed. These include e.g. single- or multi-layered chipboard, oriented strand board (OSB) or fiberboard, in particular MDF boards (medium-density fiberboard), and combinations thereof, in particular boards, with an OSB middle layer and chipboard or MDF cover layers. Or it is in the wood-based panel to a plate that can only be made in layers of wood particles provided with a binder and pressed, wherein adjacent to or between the layers of compressed chips, another material, such as a honeycomb structure may be arranged.
  • An example of the latter wood-based panel is a lightweight board with cover plates made of a wood material and a honeycomb structure, in particular cardboard honeycomb structure. Even with a lightweight board, the cover plates can be single or multi-layer chip, OSB (oriented strand board) or fiberboard, in particular MDF boards (medium-density fiberboard), as well as a combination thereof.
  • the material of the Abdeckkante namely in thin chipboard, fine particle board or fiberboard, is a material which, unlike solid wood after manufacture due to its special nature, that is, the structure of wood particles provided with a binder, can be rolled up and as Rolled goods stored and can be provided for Bekanten the wood-based panels.
  • the materials mentioned can be rolled up immediately after their production, when the binder is not completely cured, which is not possible in solid wood and veneer wood at least not to the extent possible, at least not without the formation of cracks or fractures in the edge material.
  • the step of increasing the elasticity ensures that the rolled goods can also be unrolled and glued on again without the formation of cracks or breaks in the edge material.
  • Another advantage of thin chipboard, fine chipboard and fiberboard is finally the high quality surface texture, which is characterized in particular by a relatively low porosity or surface roughness, thereby avoiding a separate process step of grinding the narrow side after sticking the cover and before the eventual application of a coating becomes.
  • thin chipboard is chipboard having a maximum thickness (thickness) of 8 mm.
  • fine-particle boards are particle boards which have chips which are post-shredded after they have been dried and before they are glued. Such plates have a particularly smooth surface and fine structure.
  • fiberboards are wood-based panels made of wood fibers provided with a binder and compressed.
  • the cover edges can be rolled up particularly well immediately after passing through the press, when the elasticity is still relatively high, since the binder has not yet set completely.
  • the elasticity of the cover edge which is provided as roll goods, is increased prior to the adhesive bonding, as will be explained in more detail hereinafter by heating and / or or moistening the cover edge.
  • the binder softens.
  • the wood particles become more elastic. In this way, the cover can be brought back into a largely flat state before it is finally applied to the narrow side of the wood-based panel.
  • the wood material from which the covering edge is formed is produced in a continuous pressing process, wherein in the pressing process the wood material and the chip cake, which later forms the wood material, in particular passes through a calender press.
  • a calendering press is preferably constructed for the purposes according to the invention in such a way that the material to be pressed is guided between a comparatively large, heated press drum and an endless steel belt.
  • a calendering press is particularly suitable for the production of relatively thin cover edges. In principle, another press can be used to produce the cover edges. It is also conceivable that the process is performed clocked.
  • the wood material from which the covering edge is formed after the step of pressing, for example after passing through the particular continuous pressing process, in the production movement direction in strips divided.
  • a cutting device preferably with a multi-blade circular saw or a laser cutting device.
  • the wood-based material from which the covering edge is formed has a width which corresponds to a multiple of the width of the later covering edge, in particular an integer multiple.
  • the cutting device for example the multi-blade circular saw or laser cutting device, then produces strips which form the cover edge or an intermediate product from which the cover edge is obtained by further fragmentation, that is to say the strips are produced by cutting in a width which is in particular at least that Width of the narrow side is equal to or greater.
  • the wood material from which the cover edge is formed first in relatively wide strips, for example in 2 to 10 strips, in particular 5 strips, a 300 to 500 mm wide, in particular 400 mm wide, are divided.
  • the kerf width when dividing is in particular at least 1.5 mm, preferably at least 2 mm.
  • the strips forming the intermediate product are then rolled together, in particular successively, onto a roll, for example with an inner diameter of 500 to 900 mm, in particular 700 mm.
  • This rolled product then has an outer diameter of in particular 1500 to 3000 mm, preferably up to 2500 mm.
  • these relatively wide strips are separated to the desired level of the final covering edge, for example, 9 strips each of 40 mm or 33 strips of 10 mm, to name just a few examples.
  • the kerf width here is also at least 1.5 mm, preferably at least 2 mm, during cutting.
  • the strips are then again rolled onto a roll, here for example with an inner diameter of 200 to 500 mm, in particular 300 mm. From this role, the individual strips are then removed.
  • the rolled product with the final strips then has, for example, an outer diameter of 1200 to 1500 mm and a width corresponding to the strip width or an integer multiple thereof. Such a role can be well handled by a person.
  • the cover edge is present after the pressing step, for example after passing through the particular continuous pressing process, and before sticking to the narrow side of the wood-based panel as an endless belt.
  • the covering edge is rolled up as mentioned, since rolls can be handled particularly well for a method for edging wood-based panels as described above. It is conceivable that the roll goods more than 100 running meters (running meters), preferably more than 250 running meters, more preferably more than 400 running meters, comprises covering material.
  • the cover edge is unrolled before the step of sticking to the narrow side of the wood-based panel as I said.
  • the covering edge is provided with a fleece, in particular cellulose fiber or textile fleece, or other fabric, for example glued, at least on one side.
  • a fleece in particular cellulose fiber or textile fleece, or other fabric, for example glued, at least on one side.
  • Such a layer absorbs stresses, in particular tensile stresses, and permits smaller roll diameters of the roll goods, which improves logistics. Also, the risk of breakage during processing, that is, when unrolling and sticking to the narrow side, reduced.
  • the cover edge has a thickness which ranges from 1 to 8 mm, preferably from 1.2 to 4 mm, more preferably from 2.2 to 3.2 mm, lies.
  • Covering edges with a thickness in the specified ranges have the advantage that, in particular in the case of the cover edge materials selected from the group consisting of thin chipboard, fine chipboard and fibreboard, on the one hand a sufficient strength is given, on the other hand, the required roll diameter of the roll goods will not be too great which improves handling.
  • a hot melt adhesive in particular ethylene vinyl acetate (EVA)
  • EVA ethylene vinyl acetate
  • EVA has proven to be particularly suitable for the cover edge materials used according to the invention with a wood-based panel connect, especially if it is the wood-based panel is a chipboard.
  • polyurethanes (PU) are suitable in the present case as an adhesive due to a particularly rapid crosslinking.
  • the cover edge is provided with an activatable layer during its production, in particular before rolling up, which may be, for example, the said adhesive, e.g. EVA or PU, can act.
  • the activatable layer is then activated in the step of adhering the cover edge to the narrow side of the wood-based panel, whereby the layer develops adhesive properties in particular itself or together with other layer causes or at least improves adhesive properties.
  • the covering edge is heated and / or moistened before the step of sticking and in particular after unrolling to increase the elasticity.
  • the moistening before, during or after heating done.
  • the cover edge is made elastic for a short time compared to the previous material state.
  • the elasticity then decreases after the covering edge has been glued to the narrow side, when the material temperature or the moisture decreases again.
  • the heating is preferably carried out by introducing steam, the so-called steaming.
  • the introduction of steam also increases the humidity at the same time.
  • the cover can also by means of high-energy radiation, in particular infrared, ultrasonic or Microwave radiation, to be heated.
  • the heating also has the advantage that an activatable layer which may optionally be present on the covering edge can be activated simultaneously, for example adhesively, made.
  • a profiling of the provided with the cover edge narrow side of the wood-based panel is performed by milling after sticking the cover on the narrow side of the wood-based panel and before applying the coating.
  • the milling, with which the material of the wood-based panel and the cover edge is brought into the desired shape and is removed with the supernatant material is clearly distinguished from a grinding, with which a particularly smooth surface is produced.
  • According to the invention is preferably dispensed with a grinding of the cover. The latter is possible only because the previously described material of the covering edge already has such a low surface porosity that even with thin coatings the surface structure of the covering edge is not telegraphed through the coating to the outside.
