<p>PURPOSE:To obtain endlessly and continuously a melamine decorative sheet having an equal quality to that obtained with a batch method, by a method wherein a set of impregnated sheets of paper are inserted between steel belts of a continuously molding press machine having the steel belts and they are pressurized and molded with tension of the steel belt and pressure through a pressurizing part with a fluid. CONSTITUTION:Respective rolls of overlay impregnated paper 1 which is obtained by impregnating overlay paper with quick hardening melamine resin, pattern impregnated paper 2 which is obtained by impregnating pattern paper with the quick hardening melamine resin, core impregnated paper 3 which is obtained by impregnating core paper with quick hardening phenolic resin and packer impregnated paper 4 which is obtained by impregnating packer paper with quick hardening phenolic resin or quick hardening melamine resin are fitted to an impregnated paper reel off device A so that they can be laminated in order from the upper one and inserted into a continuous molding press machine B. The continuous molding press machine B is constituted of a heating drum 5, endless steel belts 6, 7 and a pressurizing part 8 and driving of the endless steel belt is performed with the heating drum. A set of the sheet of the impregnated paper inserted into the continuous press machine are placed between the mirror surface steel belt 6 contacting with a surface side and the steel belt 7 contacting with a rear side and the top and bottom endless steel belts receive heat through the heating drum.</p> |
