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.
