Abstract:
1. An installation for production of plastic laminates including multi-layer laminates, comprising: a cold press with a fixed lower plate and an upper mobile plate; a metal band placed on an upper surface of the lower plate to support and draw inside the press the components of the plastic laminates consisting of bands of pre-preg and strips of copper, said metal band being unwound by electric motor-driven means from a reel placed at entry to the press and rewound onto a reel placed at an exit from the press; a pair of electrodes situated respectively at an entrance to and at the exit from the press, wherein said pair of electrodes are connected to the electric circuit of a generator of electric current of adequate power, said band maintaining continuous contact with said pair of electrodes, wherein when said components of the plastic laminates have been drawn inside the press, thereby causing closure of both the press and the electric circuit, a fraction of said metal band between the two electrodes acts as an electric resistance generating heat required for pressing.
