Process for producing plastic laminates with metal laminae, especially for printing circuits

Abstract From the Canadian patent

Process for the production of plastic laminates with copper laminae on their external faces especially for print-, ed circuits, said laminae being obtained from a continuous band (30) passing from one face to another by bends (32), made in one direction and the opposite one alternatively of the various packages placed one above the other which, band (30) being connected at its two ends (36 37) to a gen-, erator (72) of electricity acts as a set of electric resistances generating the necessary heat for producing when ade-, quate pressure is exerted on the packages by a cold press (60), close association among the various component parts and so forming plastic laminates.
