Abstract
Thin resistance wires are deposited in curved form on a thermoplastic film for the manufacture of a car glazing which can be electrically heated. The thermoplastic film is kept by vacuum on the surface of a cylindrical drum having a perforated cylindrical wall. The drum is rotated and the wire deposited and fixed on the film with the aid of a wire deposition apparatus. The wire deposition apparatus is mounted on a carriage able to move parallel to the longitudinal axis of the drum. The carriage is driven by means of a moving screw rotated by a drive motor. The drive motor is controlled by a processor via a regulating amplifier controlled by the processor in accordance with a time-travel program established in accordance with the desired curved shape of the wires.
