Abstract
A nozzle turning apparatus includes a nozzle unit that has a nozzle for sending out a wire from a tip end thereof and a nozzle holder for holding the nozzle, the nozzle unit rotatably supporting the nozzle holder, and a nozzle-holder drive member integrally provided with the nozzle unit and moved in the nozzle unit to rotate the nozzle holder. The nozzle-holder drive member is driven to turn the nozzle from a winding state to a wire processing state after a winding operation is finished. Particularly, according to the present invention, the nozzle turning apparatus includes inner unit-drive means integrally provided with the nozzle unit in the nozzle unit, for moving the nozzle-holder drive member, and outer unit-drive means independently provided from the nozzle unit outside the nozzle unit, for driving the inner unit-drive means so as to move the nozzle-holder drive member.
