ABSTRACT:
A device for coating wire with a pulverized insulating material wherein wire is coated with the insulator in an electrostatic coating machine which establishes a potential difference between the wire and the insulation and thereby causes the insulation to adhere to the wire electrostatically, without the use of solvents. After such coating, the coated wire is sintered and hardened in a sintering and hardening oven in order to form a lacquered wire with a uniform insulation thickness. Insulation thickness can be maintained at a desired value by the control device for adjusting the length of wire being exposed to the insulator in pulverized form within the electrostatic coating machine. The supply of insulator used in pulverized form is continuously fed from a reservoir into the electrostatic coating machine so as to prevent smaller and lighter particles from being first attracted to the wire, and thereby depleting such particles excessively while leaving only larger and heavier particles available for coating. The final thickness of the insulation is constantly measured by a thickness sensor and kept within a predetermined tolerance by varying the rate of feed of insulator supply to the coating machine by a valve connected to the sensor, directly as a function of insulation thickness.
