<p>PURPOSE:To reduce defects such as dents or mixing of foreign matters in a product, by a method wherein thermosetting resin solution is applied intermittently and continuously to a fiber base which is long-sized and has fixed width excepting for both side end parts, a noncoated part having a fixed width is made, a plurality of sheets of prepreg obtained by cutting the bast at the every noncoated part are piled up or metallic foils are piled up and they are heated, pressurized and molded. CONSTITUTION:Resin is applied to a long-sized base between a pickup roll 3 rotating by immersing into a resin tank 2 and a backup roll 4 rotating by coming into contact with the pickup roll 3 and cut off by a cutting machine 7 by passing through guide rolls 5, 6. When upward lifting of the backup roll 4 is performed intermittently, a noncoated part of the resin is generated by a fixed length in the meantime. Doctor blades are fixed on both end parts of the pickup roll so that the resin is not applied to both end parts of the base. The resin coated base possesses noncoated parts on its end parts on all sides at a width ratio of 0.5-20%. Obtained sheets of prepreg from an obtained resin impregnated base having fixed dimensions are piled up, hated, pressurized and molded or further copper foils are piled up, heated and pressurized, through which a laminated plate or a copper clad laminated plate is manufactured.</p> |
