Abstract
This method is for winding an inner coil of a transformer, the transformer including a ferrite core with an inner groove for receiving the winding, the ferrite core being provided with a radial inlet groove for feeding in and feeding out of the winding wire. The wire is fed through a winding mandrel with a transverse longitudinal bore. The ferrite core is pushed onto the winding mandrel and moved rotatably and axially, thereby forming the inner coil in the inner grove of the ferrite core.
