Abstract: A wire winding apparatus can reduce the burden of momentum on the side of the nozzle cooperated with the spindle shaft in winding operation, thereby enabling an effective winding operation. The winding apparatus comprises a carrier carrying at least one bobbin to be wound with wire, a nozzle for supplying the wire to be wound around the bobbin, a spindle shaft for rotating the bobbin, a working table disposed opposite to the nozzle and spindle shaft so as to introduce the carrier into between the nozzle and spindle shaft, wherein the spindle shaft is retractable relative to the bobbin carried on the carrier fed onto the working table so as to allow the bobbin to move between the carrier and nozzle.

Abstract: A coated lead wire can be solidly connected to a terminal of a coil bobbin by placing the terminal entwined with the coated lead wire into between electrodes having heating portions, and supplying electric current to the electrodes to heat the terminal entwined with the coated lead wire along with solder to melt the solder and burn off a coating layer of the coated lead wire while exerting pressure against to the terminal entwined with the coated lead wire, and directing a blow of inert gas toward the terminal entwined with the coated lead wire between the electrodes. The coating layer carbonized as the result of being burned out by heating up the electrodes can be blown out without being mixed into the molten solder, consequently to add strength to the connection between the lead wire and the terminal, to thereby form a reliable and firm connection between the lead wire and the terminal with ease.

Abstract: Disclosed is an automatic wire replacing system for use in an automatic wire coiling apparatus including spindle having bobbins, at least one group of nozzle members, and a moving/controlling mechanism. The system comprises chucking means equipped on the moving/controlling mechanism so as to chuck a nozzle bar, a nozzle carrier so disposed as to travel in a manner that it can move toward and away from the chucking means, a plurality of clipping bases so disposed that two or more of them are arranged in parallel on each side of a travelling path for the nozzle carrier, and an extending retracting means for extending a corresponding one of the clipping bases onto the nozzle carrier and retracting it from the nozzle carrier.
