AUTOMATISCHE WIDERSTANDSWICKLUNGS-WICKELVORRICHTUNG

摘要

An automatic resistor coil winding apparatus comprises a core holding portion for holding both axial end portions of a cylindrical core of a resistor, in such a manner that the core is rotatable in the direction of the peripheral surface thereof, a resistor wire supply portion having a resistor wire supply nozzle for supplying a resistor wire, a welding electrode portion for welding the resistor wire to the leading end and the trailing end of the core, and a slide base carrying the resistor wire supply portion and the welding electrode portion. The resistor wire supply portion has a resistor wire fixing mechanism and a resistor wire supply nozzle advancing/retracting mechanism, and the resistor wire supply nozzle is disposed on the slide base so as to be located at the same position as the welding electrode portion. The resistor wire supply portion has a resistor wire supply nozzle rotating portion for rotating said resistor wire supply nozzle through a predetermined angle in either direction along the axis of the core held by the core holding portion thereby changing the direction of supply of the resistance wire.
