摘要： The invention refers to an apparatus and a process for scattering material onto an endlessly rotation forming belt to provide a mat. Furthermore the invention refers to a plant for producing boards with such an apparatus and a stage of extension to enhance such apparatuses or plants.
Such an apparatus for scattering material onto an endlessly rotating forming belt to provide a mat or at least one layer of a mat to be pressed into a board has an opening (14) for receiving the material (6) and a mechanical scattering device (2) for the received material (6), which is arranged over the forming belt (1). Furthermore side walls (3) along the working direction (10) of the forming belt (1) are arranged which are movable crosswise to the forming belt to define the width (w) of the mat (5) between the side walls (3). The invention for the apparatus is characterized in that on the other side of the side walls (3) hence the defined width (w) guiding means and/or a conveyor is arranged adjacent to the side walls (3) which are suitable as a removing device for the excess of material (15) outside of the defined width (w) and above the forming belt (1).-

摘要： A method for manufacturing of a wood topped covering panel (200) with a bevelled edge (250) from a workpiece (200') comprising a substrate (240') and a wooden top layer (230'), the method comprising the steps of: providing a workpiece (200') comprising a front side, a back side and a plurality of side edges, the workpiece (200') further comprising a substrate (240') and a wooden top layer (230') with a thickness, wherein the front side comprises the wooden top layer (230'); providing a pressure apparatus comprising: a press (330) and a press plate (310) provided with a work surface (310A) configured to engage the workpiece (200') and at least one extended press-height (311) protruding from the work surface (310A) by a height greater than the thickness of the wooden top layer (230') and comprising an oblique surface (312) adapted to emboss a surface, the oblique surface (312) provided at an angle relative to the work surface (310A) of between 10 and 30 degrees; heating the press (330) to between 40 and 100 degrees Celsius; positioning the workpiece (200') onto the press plate (310) such that the front side faces the press plate (310) and the back side faces the press (330); moving the press (330) towards the press plate (310) such that the press-height (311) embosses the wooden top layer (230') and the substrate (240') of the workpiece (200') for between 1 second and 5 minutes to form an extended groove (231') in the wooden top layer (230') and the substrate (240'); transferring the workpiece (200') from the pressure apparatus to a milling machine; and removing material from a side edge (210') adjacent the extended groove (231') to form a wood topped covering panel (200) with a finished side edge comprising a bevel (250), wherein the substrate (240) is not exposed at the bevel (250).

摘要： L'objet de l'invention est un procédé d'intégration d'au moins un élément électronique, notamment un dispositif de rechargement R, dans un plateau de table (10), obtenu par moulage, caractérisé en ce qu'il comprend les étapes suivantes :
- Préparation d'un moule (16) doté en paroi inférieure d'au moins un piston mobile (18) en translation au profil d'un logement (26) ménagé dans ledit plateau, ledit piston faisant saillie de ladite paroi inférieure dudit moule (16),
- Dépose d'une quantité de matériau pulvérulent et/ou fibreux associé à un liant dans le moule (16) ainsi préparé,
- Pressage à froid avec une presse à froid PF de l'ensemble de la surface dudit matériau pulvérulent disposé dans le moule (16), ladite presse à froid PF comprenant au moins un contre-poinçon (22), disposé au droit du piston mobile (18), l'épaisseur Ep1 initiale étant réduite à l'épaisseur Ep2,
- Retrait de la presse à froid PF,
- Mise en place de l'élément électronique dans le logement (26) et mise en place d'un matériau de comblement du logement (26),
- Premier pressage à chaud avec une presse à chaud PC, de façon à assurer la cohésion du liant et de façon à obtenir un plateau de table (10) plan en partie supérieure,
- Retrait de la presse à chaud PC ,
- Obtention d'un plateau de table (10) avec un élément électronique intégré.-
