Abstract
Abstract APPARATUS FOR AND A METHOD OF PRODUCING INDEFINITE LENGTHS OF FLEXIBLE FLAT CIRCUITRY, SUCH AS FLEXIBLE FLAT CABLE HAVING ONE OR MORE ELECTRICAL CONDUCTORS FORMING CIRCUIT PATHS BETWEEN TWO INSULATORY LAYERS WITH OPENINGS IN PREDETERMINED LOCATIONS OF ONE INSULATORY LAYER FOR ATTACHMENT OF TERMINALS, ETC. A SHEET OF INSULATORY MATERIAL HAVING FLAT ELECTRICAL CONDUCTORS ON ONE OF ITS SURFACES IS PASSED THROUGH ONE COATING STATION AT WHICH A LAYER OF INSULATORY MATERIAL IS APPLIED TO SELECTED LENGTHS OF THE CIRCUITRY. THE SHEET IS ALSO PASSED THROUGH ANOTHER COATING STATION AT WHICH INSULATORY MATERIAL IS APPLIED TO OTHER LENGTHS OF THE CIRCUITRY AT WHICH INSULATION IS DESIRED, LEAVING UNCOATED SELECTED LOCATIONS OF THE CONDUCTOR TO PROVIDE OPENINGS FOR ATTACHMENT OF CONNECTORS AND OTHER TERMINATING AND INTERCONNECTING DEVICES.
