Definitions

  • the invention relates to a process for the production of compacts from small vegetable parts mixed with binders, in particular small wooden parts, in accordance with the features listed in the preamble of the main claim.
  • the invention is based on the object of producing pressed bodies designed as support bars, profiles, beams or the like with increased bending strength or load capacity.
  • profiles for example in I-cross section, can be made from small wooden parts, the bending strength of which is at least equal to that of profiles of the same size from grown wood.
  • the basic idea of the invention is that the pressing pressure of those pressing dies which act in the main loading direction of the object to be produced is not allowed to act directly on the body to be pressed, but via board-shaped strips which, after suitable pretreatment with adhesive or similarly acting materials have the property, on the one hand, of transferring the pressure and, on the other hand, of being firmly connected to the mixture of small parts of a vegetable nature to be pressed.
  • the invention does not exclude that the board-shaped stiffeners used in accordance with the main claim can also be connected to the outer surfaces of the profile web according to the feature of FIG the bending stiffness.
  • the invention also goes so far as to provide the other or vice versa or both together instead of one planking.
  • the invention provides, in accordance with the feature of claim 4, to use two-layer or multilayer board-shaped strips for the planking. These can be lamellae or strips different in terms of their wall thickness, which can also consist of different materials.
  • the invention also relates to the product that can be produced by the method, which differs from the direct product to be expected from the method in that the connecting surface between the pressed, small-part profile body and the board-shaped strips is uneven, this unevenness towards Profile body can be arched protruding.
  • This uneven connection surface has the advantage that the board-shaped strips form a positive connection with the pressed profile body consisting of wooden parts, not only via the introduced binder, but also via the convex connection surface, compared to the pressed profile body.
  • the board-shaped strips thus not only increase the load-bearing or bending strength of the manufactured profile, but also the torsional rigidity.
  • the deformation tool is formed by the Prc-i3stempel 10, 11, 12, 13, which are movable along the guides 14 and enclose the cavity 9 between them.
  • the lateral press rams 12, 13 are in the retracted position.
  • the upper press ram 10 (cf. FIG. 3) is withdrawn so far that the filling material 21 (cf. FIG. 3) can be poured into the cavity 9.
  • the lower ram 11 is also in the retracted position.
  • a board-shaped strip 19 is placed on its surface, which corresponds to the length and width of the cavity 9 and can be moved with the press ram 11.
  • This board-shaped strip 19 can be made of different materials, e.g. B. consist of pressure-transferable material such as natural wood, fiber-reinforced plastic layer and the like ..
  • This strip 19 is also on the inside, i. H.
  • the filling material 21 is poured into the cavity 9, which preferably consists of small wooden parts mixed with binders.
  • the cavity 9 which preferably consists of small wooden parts mixed with binders.
  • other small plant parts such as. B. crocheted straw and the like to use. This dosage and the gluing of these small parts is to be considered as state of the art and therefore requires no explanation.
  • the individual board-shaped strips 19, 20 can consist of two or more layers 25, 26 which have previously been glued together. With such layers 25, 26 there will of course be a slight curvature of the connecting surface 23.
  • board-shaped strips 22 covering the side surface of the web 3 can also be used, which consequently are firmly connected by the side press punches 12, 13 during the pressing process according to FIG are brought with the small parts forming the web 3. It is left to the person skilled in the art to design the edge areas of the lateral press rams 12, 13 so that the board-shaped strips 22 are, as it were, embedded in the web 3 and from there the transition to the belt 2 takes place continuously.

Claims (6)

1. Procédé de fabrication d'objets par compression, constitués de particules végétales, notamment de particules de bois, mélangées à des liants, qui consiste à remplir de particules une empreinte formée de plusieurs fouloirs de compression et appliquer successivement par les fouloirs de compression et tout en chauffant une pression dans des directions différentes à la masse, de remplissage, caractérisé en ce qu'il consiste, pour fabriquer des barres porteuses, des profilés, des poutres, ou des objets analogues par compression, à introduire dans l'empreinte au moins une bande en forme de planche et, de préférence, deux bandes opposées en forme de planche, en matériau apte à transmettre la pression, par exemple en bois naturel, en couches de matière plastique renforcées par des fibres ou en matériaux analogues qui sont munies d'une colle et/ou d'un revêtement en résine de matière plastique et qui délimitent entre elles les particules, puis à appliquer d'abord, par les fouloirs de compression, associées à la région de la membrure et par l'intermédiaire des bandes en forme de pianche, une pression aux particules, puis à mettre les fouloirs de compression associés aux surfaces latérales l'un en face de l'autre en position de compression, et enfin à effectuer une post-compression des régions des membrures de l'objet par compression, tout en maintenant la pression appliquée sur les surfaces latérales avant de durcir, par action de la chaleur et en maintenant la pression, l'objet moulé par compression.
2. Procédé suivant la revendication 1, caractérisé en ce qu'il consiste à appliquer. d'abord une bande en forme de planche, sur le fouloir de compression formant la surface du fond de l'empreinte, puis à remplir l'empreinte des particules et enfin, à appliquer sur le remplissage la deuxième bande en forme de planche.
3. Procédé suivant la revendication 1 ou 2, caractérisé en ce que les surfaces extérieures de l'âme du profilé sont également bardées de bandes en forme de planche.
4. Procédé suivant la revendication 1 ou l'une des revendications suivantes, caractérisé en ce qu'il consiste à utiliser, pour le bardage, des bandes en forme de planches à deux couches ou à plusieurs couches.
5. Poutre résistant à la flexion, préparée par le procédé selon la revendication 1 ou 2, caractérisée en ce que la surface de liaison entre les profilés comprimés et constitués de particules et les bandes en forme de planche, n'est pas plane.
6. Poutre suivant la revendication 5, caractérisée en ce que la surface de liaison est incurvée en étant convexe en direction du profilé.
