<p>PURPOSE:To obtain a laminated board, in which there is no residual bubble and which has a smooth surface, by covering the upper and lower sections of long-sized sheet-shaped base materials, which are decompressed and deaerated and superposed, with films or metallic foils coated with a solventless cured resin liquid. CONSTITUTION:A plurality of long-sized sheet-shaped metals 1 are superposed while being passed in a decompression partitioning chamber 7. The upper and lower sections of the sheet-shaped base materials 1 are covered with films or metallic films 4 coated with a solventless thermo-setting resin liquid immediately after the base materials 1 are discharged from the decompression partitioning chamber 7, and the sheet-shaped base materials 1 are impregnated with the resin liquid.</p> |
