摘要: A godet for heating an advancing synthetic filament yarn is provided, the godet comprising a plurality of stationary primary windings and, with respect thereto, a magnetically conductive, rotatably supported godet jacket. The godet jacket is coupled with the primary windings via a defined radial clearance extending between same and the side walls of the primary winding carrier for generating induced currents. The carriers are constructed such that their transformer sheets radially overlie each other in the region of their channel bottom, thereby shielding the magnetic flux outward, in particular toward the coil support.
