A toroidal coil winding machine for winding a wire in a coil on a work such as a toroidal core of a magnetic head comprises, as the principal components, a rotary table for fixedly holding a work thereon, capable of being turned intermittently through an angle of 180 DEG at a time, a pair of mobable arms disposed on the diametrically opposite sides of the rotary table, respectively, provided with mechanical hands for gripping a wire, respectively, and capable of being moved between the respective front positions and the back positions, a clamping device for holding one free end of the wire, mounted on the rotary table, a loop holding device for holding loops of the wire wound on the work while the rotary table is stopped, mounted on the rotary table, a wire reel for feeding the wire, a wire holder disposed near the wire reel for temporarily holding the wire drawn out from the wire reel, and a cutter disposed near the wire holder for cutting the wire in a predetermined length. The movable arms are advanced to the front positions, respectively to transfer the other free end of the wire from one to the other or from the other to the one of the mechanical hands. After the other free end of the wire has been passed through an opening formed in the work and has been gripped by one or the other of the mechanical hands, the rotary table is turned through an angle of 180 DEG to wind the wire on the work.
