摘要： A method for manufacturing a laminate includes steps of forming a laminated combination of synthetic resin sheet material with a metal foil laminated each other, thermoforming under a pressure the laminated combination while supplying an electric current to the metal foil, and, after termination of the current supply, cooling thus obtained laminate while further applying a pressure, whereby the laminated combination can be uniformly heated into its core part to allow the laminate of uniform quality to be obtained, while shortening manufacturing lead time and minimizing surface roughness.

摘要： A method and apparatus for manufacturing laminates are arranged for forming a laminate block by sequentially folding back continuous metal sheets 3 and 4 drawn through outlets 16 out of rolls 5 and 6 of the sheets wound on reels 1 and 2, with synthetic resin sheet members 9 and interlayers 10 alternately interposed between the metal sheets, into multiple stages, and pressing the thus stacked laminate block while electrically heating the continuous metal sheets 3 and 4 in the laminate block, wherein the stacking is performed while keeping the continuous metal sheets 3 and 4 in tension between the outlets 16 of the reels 1 and 2 and each end edge of the laminate block 12.
