Definitions

  • the invention relates to marked wood fiber insulating materials, in particular plates and mats.
  • Holchie insulating materials are produced in continuous processes from the essential raw materials wood fibers and a thermosetting or thermoplastic binder. At the end of the process, the wood fiber insulation materials are cut into palletized sizes or rolled up into a container.
  • the wood fiber insulation materials are produced in mat or plate form whose large surfaces have, for example, different properties.
  • one side can have a flame protection, while the other side has a moisture protection.
  • the density may continuously decrease from one large area side to the other large area side to allow for special applications.
  • the processor Since the wood fiber insulating materials are processed on site, that is at the construction site, the processor must have a Editing aid to be given, which ensures the correct processing. For the identification of the manufacturer, the dimensions, the special properties but also as a processing aid for the cutting on site to produce little waste, it is therefore necessary to mark one or both sides of the finished wood fiber insulation to avoid processing errors.
  • the fiber mat For the marking of mineral fiber products, it is from the DE 296 03 918 U1 It is known to provide the fiber mat with a grid-like carrier material fixed on at least one main surface of the fiber mat, as well as an identification strip arranged between the carrier material and the fiber mat, which has a label on its side facing the carrier material for identification.
  • US 2005/0223668 A1 relates to a fibrous insulation assembly comprising an insulating sheet, a sheet of kraft paper and an asphalt-containing sheet.
  • the plate has markings that are mechanically inserted.
  • WO 92/13150 A1 relates to a process for the production of mineral fiber boards, which can be used as a plaster base.
  • the mineral fiber boards can be marked by means of a marking device.
  • the marking is carried out for example by heating by means of a flame, hot air or infrared radiation which leads to a local discoloration of the organic binder.
  • WO 02/20911 A1 describes a mineral wool product with markings on the surface. These markings are produced inter alia by pressing in suitable shapes or by using embossing elements. The introduction of the markings can be done before or during compression and curing in an oven.
  • the invention is based on the object to provide marked wood fiber insulation, wherein the marking is carried out during the production of wood fiber insulation without an additional effort.
  • the starting materials namely wood fibers and binder mixed
  • the starting materials namely wood fibers and binder mixed
  • the binders can be added as binder fibers or glue. It does not matter if the glue is added as a powder or in liquid form. Due to the heat, the raw materials are connected and form the wood fiber insulation sheets. If special properties, such as moisture protection or flame retardancy, are desired, these additives can be added even when the wood is defibered. Thus, the resulting mat is homogeneously impregnated over the cross section.
  • the special means for example for the flame retardant before entering the hardening furnace or heating-cooling furnace, hereinafter referred to as furnace, applied. Due to the high temperatures in the oven, the added products discolor the added products. The discoloration depends on the temperature prevailing in the oven. The inclination for discoloration on exposure to heat used according to the invention for the desired identification of the product to be produced.
  • the passage of the wood fiber binder mixture with additives through the hardening furnace takes place between two conveyor belts.
  • the wood fiber binder mixture is flowed through from above and / or below by hot air.
  • thermosetting binders cure.
  • Thermoplastic binders are cooled after heating to obtain the desired bond.
  • the result is the desired wood fiber insulation.
  • a more or less pronounced discoloration of the wood fiber insulation material occurs. If a special air guidance is now provided by the design of the conveyor belts or by internals in the oven, different degrees of discoloration occur on the surface (s) of the finished product.
  • the embodiment provides to close the existing of a wire mesh conveyor belts in the longitudinal direction and / or transverse direction at one or more points over a certain area.
  • the same effect is achieved when built-in fittings are provided over its length in the oven, which reduce the heat supply to one or more locations on a certain width to wood fiber binder mixture, such as channels or selectively strengthen, for example by additional energy sources.
  • This type of marking is preferably suitable for a line marking of wood fiber insulation.
  • the different heat effect can also be achieved by imposed on the surface of the wood fiber binder mixture templates or stamp.
  • the templates or stamp are provided according to the desired markings with openings. This type of marking is particularly suitable for wood fiber insulation panels.
  • the templates or stamp are arranged in the oven so that each section for a wood fiber insulation board has the necessary markings after assembly to the desired plate size.
  • stencils or stamps are used which have the desired markings in a raised form on the side facing the wood-fiber binder mixture.
  • the wood fiber insulation material is slightly more compacted at the points of the elevations on the template or the stamp, since the stencils or the stamp press into the wood-fiber-binder mixture.
  • the marking can be recognized as embossing on the insulating material.
  • FIG. 1 shows a plan view of a wood fiber insulation board 1, which is obtained by packaging from the exiting the oven belt in a known manner.
  • a marking 2 is achieved as a color change in the longitudinal direction.
  • FIG. 2 a section of a wood fiber insulation mat 3 is shown, which has not only a line-shaped marking 2 in the longitudinal direction, but in addition also a 90 ° rotated with respect to the longitudinal direction marker 4.
  • marks 4 can be provided in an angle rotated by 90 °, but also any other angle in place or in addition to the 90 ° rotation of the mark 4. Since it is the markers 2, 4 only to small areas of the total surface Holzmaschinedämmstoffe is, there is no reduction in quality.
  • FIG. 3 shows a marking of a wood fiber insulation board 2, obtained by a template.
  • a template for marking a company identification 5 and a product marking 6 was omitted.
  • the template which is here designed by milling corresponding to the desired marking on the wood fiber-binder mixture before passing through the oven, the marks 5, 6 are obtained by color differences on the surface of the finished product.
  • the mark is obtained on a wood fiber insulation board 2 by a template with a raised surface.
  • the raised parts of the template or of the stamp have pressed into the surface of the wood fiber insulating material and give the desired markings 5, 6.
  • the variants can be combined installation of heat reducers or heat amplifiers over a certain surface of the exiting wood fiber binder mixture with the particular design of the conveyor belt and / or the stencils or stamps in any way to achieve optimum labeling.
