Definitions

  • the present invention relates to a method in which, with the aid of several units, an end product can be produced that is rather complicated and in which a method using gluing has been utilized.
  • the object of the present invention is to provide a rational method for utilizing pure timber and thus achieve considerable savings in the manufacture of wooden products.
  • the starting materials are the following types of timber: spruce, pine, birch, beech, oak, larch and timber with equivalent properties.
  • a slim trunk with a top diameter of between 80 and 140 mm is selected. This trunk is placed in a water bath so that it acquires a moisture content between 20 and 40 %.
  • the water suitably has a temperature somewhere between 15° and 25°.
  • each part contains a core part having at least 8 annual rings. This method makes it unnecessary to remove the bark.
  • the desired end product is obtained when the individual timber units of desired dampness have been joined together to form different bodies.
  • These wooden sleepers are manufactured in exactly the same way as described above, namely tree trunks are placed in a water bath in order to acquire a certain degree of dampness, and are then processed to bars of substantially rectangular shape, provided with polyurethane glue or the like and joined together so that they form sleepers, after which the sleepers are subjected to pressure.
  • sleepers it is obvious that not every unit in the sleeper need be as long as the sleeper itself. The latter may consist of several parts arranged one after the other and very inexpensive sleepers can be produced in this way.
  • the unit it is extremely advantageous when producing a unit in accordance with the present method, for the unit to consist of heartwood and to have at least eight annual rings.

Abstract

L'invention concerne l'assemblage de différents éléments en bois par collage par voie humide. Le procédé de l'invention consiste à placer des troncs d'épicéa, de pin, de bouleau, de chêne et de mélèze, ayant généralement un diamètre supérieur d'environ 80 à 400 mm, dans un bain d'eau, de sorte que la teneur en humidité voulue soit atteinte, après quoi ils sont sciés en différents morceaux et assemblés à l'aide de colle, sous pression.
