Abstract: A coil winding apparatus includes: a core rod feeding unit configured to feed a string-shaped core rod from a core rod nozzle; a core rod drawing unit configured to draw out the core rod; a wire rod feeding unit configured to feed a wire rod towards the core rod; a rotator capable of rotating about the core rod nozzle; the guide member provided on the rotator, the guide member being configured to clamp, with the core rod, the wire rod that has been fed from the wire rod feeding unit; and a rotating unit configured to rotate the rotator to rotate the guide member together with the rotator so as to revolve the wire rod around the core rod in a vicinity of the core rod nozzle.

Abstract: A wire stranding apparatus, comprising: a core wire moving mechanism configured to move a core wire in an axial direction; a spool configured to feed a wound wire by rotation; a revolving mechanism configured to revolve the spool about the core wire; a rotation driving mechanism configured to feed the wire by rotating the spool, the wire fed from the spool being spirally wound on an outer periphery of the core wire moving in the axial direction by revolution of the spool; and a control device including a wire speed obtaining unit configured to obtain a speed of the wire to be wound on the core wire and a rotation driving mechanism control unit configured to control the rotation driving mechanism such that the speed of the wire obtained by the wire speed obtaining unit has a predetermined value.

Abstract: A coil winding apparatus includes: a cylindrical core rod nozzle configured to allow insertion of a narrowed core rod; a wire rod feeding unit configured to feeding a wire rod to the core rod nozzle; a wire rod holding tool configured to hold the wire rod fed from the wire rod feeding unit; a core rod winding unit configured to wind the wire rod drawn from the wire rod feeding unit by rotating the wire rod holding tool around the core rod nozzle; a core rod drawing unit configured to draw the core rod from the core rod nozzle; and a coil drawing unit configured to draw a wound wire formed by winding the wire rod on an outer periphery of the core rod nozzle from the core rod nozzle.
