<p>The method involves forming a middle layer (17) between two surface layers on an endless form band (19), during the production of a pressed material mat. The middle layer is formed from chips and/or cuttings (11) and dosed filler materials (10). A material stream of chips and/or cuttings, falling from a filler material reservoir (2), is conveyed above a spreading head (20) or directly into the head. The chips and/or cuttings and the filler materials are uniformly mixed in the head. The mixture is delivered from the head under the production of a predetermined uniform sealing profile. An independent claim is also included for an apparatus for spreading a pressed material mat in succession during the production of light material boards.</p> |
