Date Aug. 18, 1994In the process for making plastic laminates a stack of prepreg bodies is provided with electrically insulated rigid flattening sheets between each pair of adjacent prepreg bodies. Two continuous metal bands are passed in a serpentine manner back and forth through the stack from one side to the other, while being spaced from each other, so that each metal band contacts only one side surface of each prepreg body and the bends formed in each of the two metal bands are distributed on opposite sides of the stack. After the stack is formed with the metal bands passing through it, an electric current is passed through both metal bands from one end of each band to its opposite end to heat the two metal bands and thus the prepreg bodies and pressure is applied to the stack. After heating and pressing the stack, the two metal bands are cut through at the bends to form the plastic laminates. |
