ABSTRACT:
In the fabrication of wood material panels, processed wood particles are coated with a binder free of a hardener and then are spread in a fleece on a support surface. The fleece is then compacted and pressed to form the panel. Before the compacting step, microcapsules are introduced into the fleece. The microcapsules have enclosing walls that do not react with the binder and contain a hardener in the gaseous phase or in the binary phase with a gaseous carrier agent. When the fleece is compacted, the capsule walls are destroyed and the hardener is released into the fleece. The microcapsules containing the hardener are produced in a device located adjacent to the inlet end of the press so that there is only a short distance between the device and a mixing station where the microcapsules and the bonded processed wood particles are mixed. The mixing station is located just ahead of or at the spreading station where the mixed wood particles and microcapsules are formed into the fleece. The spreading station is located immediately adjacent the inlet to the press.
