PURPOSE:To facilitate a coil tap forming operation, by employing a rotary plate having in its central part of a tap lead-out hole and a multiplicity of pins, and arranging such that a twist pin can emerge and withdraw out of and from this lead-out hole. CONSTITUTION:A rotary plate 8 is rotated for indexing and is provided with a multiplicity of pins 51, 52 upstanding on two concentric circles at predetermined pitches, respectively. An electromagnetic wire 41 is wound on a specific one of these pins to form a unit coil. The rotary plate 8 is rotated to form unit coils successively. In this case, a tap lead-out hole 8-1 is formed in the central part of the rotary plate 8. A twist pin 13 is adapted to be able to emerge and withdraw from the hole 8-1, and a coil tap 16 is led out from the hole 8-1. Thus, the tap forming operation is facilitated, and it is made possible to greatly reduce the time required for the coil winding operation. |
