Abstract: A continuous method for producing a lightweight sandwich panel comprises providing a scattered layer of glue-coated woodchips; pressing this layer and bonding the wood chips under pressure and temperature conditions such that a high vapor pressure is built up in the center between the cover layers; relieving the pressure by moving the pressing surfaces away from one another, whereby the chipboard tears open in the center due to the built-up vapor pressure and divides into two cover layers of equal thickness; moving the cover layers apart; introducing a foam system that can be foamed and cured to form a hard foam between the cover layers; bringing the cover layers together to the nominal thickness of the lightweight sandwich panel to be produced and holding the pressure until the intermediate layer has finished reacting; and finishing the lightweight sandwich panel.
