Definitions

  • the present invention relates to a procedure as defined in the preamble of claim 1.
  • master sheets e.g. 8 x 16 ft. or 9 x 20 ft.
  • master sheets e.g. 8 x 16 ft. or 9 x 20 ft.
  • Such a method requires relatively expensive investments on equipment.
  • it involves high operating costs.
  • the method is too complicated and expensive especially in cases where only certain standard sizes are needed as end product ⁇ e.g. 4 x 8 ft. or 5 x 9 ft.) .
  • master sheets e.g. 8 x 16 ft. or 10 x 18 ft.
  • master sheets e.g. 8 x 16 ft. or 10 x 18 ft.
  • a drawback with this method is inflexibility especially in cases where two or more sheet sizes, especially sheet lengths, are to be obtained as end product.
  • the purpose of the present invention is to avoid the drawbacks of prior art and to achieve a simple and substantially more flexible procedure for producing cut- to-size sheets on a press line.
  • the procedure of the invention has numerous significant advantages. It allows flexible production of several sheet sizes, because a desired length can be selected for each component raw board.
  • Fig. 1 presents an apparatus applying a procedure according to the invention
  • Fig. 2 presents a diagram representing the procedure of the invention.
  • a mixture of wood material and binding agent is pressed in a press 1 to produce a raw board 2, which is conveyed on a carrier 11, such as a roller track, in the direction indicated by the arrow.
  • the raw board 2 is divided into at least two component raw boards 3, 4, preferably by sawing 5.
  • the raw board is divided into two component raw boards.
  • the component raw boards 3, 4 may differ from each other in respect of width.
  • the blade of the long saw 5 is preferably adjustable in the lateral direction, permitting the widths of the component raw boards to be quickly changed.
  • the long saw 5 may have several blades, depending on the number of component raw boards. Alternatively, it is possible to use several successive long saws.
  • the component raw boards 3, 4 are cut into sheets 3' , 4' of a given size, preferably separately.
  • a separate cutting device 6, 7, preferably a saw is provided for each component raw board.
  • the saw 6, 7 used for the crosscutting may be a so-called crosscut saw for moving material, known in itself, such as e.g. the Sunds Defibrator FCC (Flying Cross-Cutting Saw) .
  • FCC Fluor Cross-Cutting Saw
  • at least adjacent component raw boards 3, 4 can be brought to different levels at least in the cutting area. This can be implemented e.g. by raising or lowering the height position of at least one of the supports 12, 13 carrying adjacent component raw boards 3, 4 at least partially in relation to the support 12, 13 carrying the adjoining component raw board.
  • the cutting apparatus 6, 7 is typically equipped with a circular saw, which may be of a type sawing from above or a type sawing from below with respect to the level of the component raw board 3, 4.
  • the sheets 3', 4' of desired size produced by crosscutting the component raw boards 3, 4 are moved on e.g. by means of conveyors 14, 15 to a further treatment stage, such as a stacking stage.

Abstract

Cette invention se rapporte à un procédé pour produire des feuilles de matériau à base de bois coupées en grandeur donnée, procédé dans lequel on produit une planche grossière continue (2) en pressant un mat de matériau sous une presse à fonctionnement en continu (1). Dans ce procédé, la planche grossière (2) est divisée dans le sens de la longueur en au moins deux planches grossières constitutives (3, 4) de largeur désirée, puis chaque planche grossière constitutive (3, 4) est découpée en feuilles (3', 4') de longueur désirée.
