发明名称 Composite panels and methods of making composite panels
摘要 A composite panel, with a core member; a cover plate glued to the upper side of the core member, and also a cover plate glued to the lower side; and with an edge strip secured to the rim of the core member. The composite panel substantially avoids dimensional tolerance problems which can arise at the edge strip, and high demands made during technical use, and by designers, can be met by the panel. The edge strip includes two corner strips which extend centrally from the edge strip and which have a width which is precisely, i.e. with negligible tolerance, predetermined. The edge strip also has a central strip. The core member comprises peripheral ledges which extend centrally from the upper and lower sides with precisely predetermined thickness, and an intermediate component arranged between the ledges. The thickness of the peripheral ledges is adapted to the width of the corner strips of the edge strip.
