Definitions

  • the invention is directed to a method for producing a chipboard from at least three layers.
  • a continuous production of chipboard has long been known ( DE-44 34 876-A1 ), taking, as an example, a lower layer in a thickness of 2-5 mm of fine chips with a spall diameter ⁇ 2 mm, a middle layer of chips with a spud diameter of about ⁇ 15 mm and an upper layer, which in turn is formed of fine chips with a spall diameter ⁇ 2 mm, which are exposed to high pressure and temperature to form the chipboard.
  • Lightweight panels which have a core of Balsastirnholz are also known per se. So by a display of the applicant at the Nuremberg Toy Fair in February 2000, as well as from the DE-31 00 094-A or the DE-20 11 865-B which show an end-skin middle layer with under- and over-laid plywood layers or cover layers. This also applies to the DE-36 25 534-A or the DE-39 27 538-A or from 1943 originating US-2 479 342 , However, there is a significant disadvantage in that first all layers, whether covering layer, middle layer or lower layer, manufactured separately and then connected to each other, eg glued, must be.
  • the object of the invention is to make the Balsastirnholztechnologie available for the production of particle board, such that an endless product is formed from a core of Balsastirnholz with underlay and on-laid fine layer in a single manufacturing process.
  • the middle layer is formed from coarse chips, also produce balsa wood chipboard by means of a feeder, the middle layer of Balsastirnholzbrettchen or Balsastirnholzplatten is formed.
  • the fact that the light chipboard is produced in a single work process, manufacturing speed, energy savings and easy control of product quality can be achieved.
  • the invention provides that wood chips or sawdust, wood shavings, grinding chips, grinding flour, abrasive fibers made of wood or other organic materials, such as straw, hemp or the like., Is used as a layer-forming fine granules.
  • glass fibers or fabrics can be used, it goes without saying that even mixtures the above materials can be used.
  • the invention provides in an embodiment that the applied Balsastirnholzbrettchen and / or plates are glued on one side or both sides (for gluing technology s GB-1 439 578 ).
  • At least one of the two outer sides of the endless chipboard produced in this way is provided with a further surface coating.
  • This surface coating may for example consist of a coating, but it can also be formed from other laminated films, veneer wood or the like.
  • a middle balsam wood layer 3 and a lower fine layer 4 wherein a fine layer is a mixture of fine chips with a chip diameter ⁇ 2 mm in connection with adhesive, which via a pressure / heater compacted and hardened, as described below.
  • FIG. 2 A simplified representation of a manufacturing plant for such lightweight chipboard shows Fig. 2 ,
  • fine chips 7 are applied from a reservoir, wherein the carrier tape 5 before, simultaneously or subsequently via a spraying device 8 with glue, glue or the like is acted upon.
  • Fig. 2 generally designated 9, applied, which is indicated by the double arrow 10.
  • the surface of the Balsastirnholzplatten 9 can be sprayed with a further adhesive supply 8a with adhesive. From a further reservoir 6a then trickle on the surface of Balsastirnholzplatten fine chips 7a.
  • the sandwich composite can then be applied from above via another endless belt 5a, as shown in FIG Fig. 2 is indicated, wherein the package of lower endless belt 5 of the lower layer of fine chips, the Balsastirnholzplatten and the upper layer of fine chips of a pressure / heating unit, generally designated 11, is fed, which compresses the entire composite and cures the fine chips with adhesive.
  • endless chipboard 1a produced in this way can be provided with a surface lamination 12, the endless chipboard 1a then being provided with a cutting device, in Fig. 2 indicated and designated 13, is divisible into its final plate length.
  • a multi-layer plate can be produced, for example with two successive and separated by a fine layer of chips Balsastirnholz Anlagenen.
  • a comparable in the load with conventional chipboard light chipboard to 2/3 lighter it is therefore easily used and economically producible for a variety of additional applications.
