Hagl for jakt i våtmarksområder, samt fremgangsmåte for fremstilling av slik hagl

摘要

In a method of producing a building element, which consists of glued-together layers of wood (15-17) and which is destined for the making of a laminated wooden floor, such as a parquet floor, at least two layers of wood (15-17) are placed one above the other with an intermediate layer of glue so as to form a base unit (14). The base unit (14) is compressed between two press plates (10, 11) extending in parallel with the layers of wood (15-17). During compression, an electromagnetic high-frequency alternating field is applied across the base unit (14) in order to harden the glue in the layer of glue. The electromagnetic high-frequency alternating field is applied across two electrode plates (12, 13) which extend perpendicular to the press plates (10, 11) and which, during the compression of the base unit (14), are placed on both sides of the base unit in the vicinity of two opposite side edges thereof.
