PURPOSE:To prevent the warpage and twist of a metal foil clad laminated sheet at the time of continuous production by a method wherein a plurality of resing impregnated base materials and metal foils are integrated under heating without applying pressure and subsequently pressed for a definite time to be re-cured before cut into a predetermined dimension. CONSTITUTION:A long strip material impregnated with a resin and an outermost metal foil are integrated by a laminating roll 5 to form a laminate which is, in turn, sent into a curing oven. The curing oven 4 can perform the curing of the laminate under a non-pressure or pressure state. After the laminate sent into the curing oven 4 is heated and cured under non-pressure, the laminate is pressed for a definite time or pressed or heated for a definite time and subsequently re-cured at high temp. to be cut into a specific dimension. Otherwise, after the pressure and heat are applied to the laminate for a definite time, the laminate may be cut without being re-cured. |
