Abstract
In a winding apparatus (1) of a stator (multi polar armature) winding a bundle of plural wire rods (5) on a circular core in which teeth (winding core) (9) are arranged circularly, an index mechanism (11) rotating the circular core (8) around its central axis, a core turning mechanism (30) turning the index mechanism (11), a nozzle (3) reeling out a plurality of wire rods (5), and a nozzle travel mechanism (15) traveling the nozzle in the three dimensional directions are provided. The index mechanism (11) and the nozzle travel mechanism (15) travel the nozzle (3) around each tooth (9) to wind the wire rods around each tooth (9), as well as the core turning mechanism (30) turns the index mechanism (11) and also the circular core (8) to eliminate the twist produced in the wire rods (5) wound around tooth (9).
