<p>Continuous process for manufacturing, in a cold press (11), plastic laminates with copper laminae and intermediate layers of prepreg, by multicomposition bands (78, 98, 118) with copper laminae (62, 63, 82, 83, 102, 103) and bands (73-75, 93-95, 113-115) of prepreg continuously fed in from reels (60, 61, 70-72) which, placed one upon another, pass through the press (11), endothermic heating being provided by circulating electric current in the fractions of copper laminae (62, 63, 82, 83, 102, 103) which remain pressed in the press (11) during cyclic closing stages.</p> |
