ABSTRACT:
In an apparatus for winding coils for a stator of an electric motor, a guide plate with a plurality of guide steps is disposed movably along a coil former member and is lowered more quickly than the coil former member so that one of the guide steps is located at the border between two adjacent steps of the coil former member. The leading wire can be smoothly led by each guide step without decreasing a winding speed when a winding operation is transferred from a step of the coil former member to an upper step thereof.
