Laminates, esp. industrial laminates, are made by covering both sides of a prepreg (1) with metal foil, esp. copper foil. Press plates (3) are covered top and/or bottom (2o,2u) with sections of copper foil cut from an upper and lower continuous foil line. A stack of prepregs (1) and covered press plates (3) is then assembled in a press. When assembling the stack, every second press plate is turned over through 180 deg and the top (3b) and bottom (3a) plates are covered only on the lower (2u) and upper (2o) sides respectively. In this way each prepreg is covered on both sides by foil from only the upper or only from the lower foil line.
