Abstract

A transformer winding device, a method and a transformer are disclosed. The transformer winding winding device includes a rotary device configured to extend along an axis of rotation and configured to receive a transformer winding to be wound, at least one device configured to provide a plurality of insulation strips, and a comb-like guide device. The comb-like device is configured to deflect the plurality of insulation strips into at least one common winding plane and fed parallel to one another, at an angle to an axis of rotation, to the transformer winding to be wound. The comb-like guide device can include at least a first guide device element for a first group of insulation strips and a second guide device element for a second group of insulation strips, wherein the first and second guide device elements are offset with respect to one another in terms of axial length.
